Installation


This chapter provides procedures for installing the Cisco ONS 15454. Chapter topics include installation equipment, rack installation, equipment access, power and ground installation, backplane interface connections (alarms, timing, craft interface, etc.), card turn-up procedures, cable installation, cable management, and hardware specifications.


Note   The Cisco ONS 15454 assembly is intended for use with telecommunications equipment only.



Warning   The ONS 15454 is intended for installation in restricted access areas. A restricted access area is where access can only be gained by service personnel through the use of a special tool, lock, key, or other means of security. A restricted access area is controlled by the authority responsible for the location.



Warning   The ONS 15454 is suitable for mounting on concrete or other non-combustible surfaces only.



Warning   The ONS 15454 should be installed in the lower rack position or mounted above another ONS 15454 unit.



Warning   The ONS 15454 must have 1 inch of airspace below the installed unit to allow air flow to the fan intake. The air ramp (the angled piece of sheet metal on top of the shelf assembly) provides this spacing and should not be modified in any way.



Caution   Unused card slots should be filled with a blank faceplate (Cisco P/N 15454-BLANK). The blank faceplate ensures proper airflow when operating the ONS 15454 without the front door attached.


Note   The ONS 15454 is designed to comply with GR-1089-CORE Type 2 and Type 4. Install and operate the ONS 15454 only in environments that do not expose wiring or cabling to the outside plant. Acceptable applications include Central Office Environments (COEs), Electronic Equipment Enclosures (EEEs), Controlled Environment Vaults (CEVs), huts, and Customer Premise Environments (CPEs).


1.1 Installation Overview

When installed in an equipment rack, the ONS 15454 assembly is typically connected to a fuse and alarm panel to provide centralized alarm connection points and distributed power for the ONS 15454 system. Fuse and alarm panels are third-party equipment and are not described in this documentation. If you are unsure about the requirements or specifications for a fuse and alarm panel, consult the documentation for the related equipment.

You can mount the ONS 15454 in a 19- or 23-inch rack. The shelf assembly weighs approximately 55 pounds with no cards installed. An ONS 15454 is installed in a rack using reversible mounting brackets on each side of the shelf. The ONS 15454 features a front door for added security, a fan tray module for cooling, and extensive fiber management space.

ONS 15454 optical cards have SC connectors on the card faceplate. Fiber optic cables are routed into the front of the destination cards.

DS-1, DS-3, DS3XM-6, and EC-1 units require special Electrical Interface Assemblies (EIAs) to provide the coaxial connection points for the shelf. In most cases, EIAs are ordered with the ONS 15454 and come pre-installed on the assembly backplane. See the "Backplane Covers" section for more information about the EIAs. DS-1 units support wire wrap twisted pair connections or an AMP CHAMP EIA. DS-3, DS3XM-6, and EC-1 units support BNC or SMB EIAs on the assembly backplane.

The front door of the ONS 15454 shelf allows access to the shelf assembly, fan tray, and fiber management area. The back panel provides access to alarm contacts, external interface contacts, power terminals, and BNC/SMB connectors.

The ONS 15454 is powered using -48V DC power. Positive, negative, and ground power terminals are accessible on the backplane.


Warning   Read the installation instructions before you connect the system to its power source.

1.3 Installation in a Rack

The ONS 15454 is easily mounted in a 19- or 23-inch equipment rack. The shelf assembly projects 5 inches from the front of the rack. It mounts in both EIA-standard and Telcordia-standard racks. The shelf assembly is a total of 17 inches wide with no mounting ears attached. With the mounting ears attached, the shelf assembly is 19 inches wide. Ring runs are not provided by Cisco and may hinder side-by-side installation of shelves where space is limited.

The ONS 15454 measures 18.5 inches high, 19 or 23 inches wide (depending on which way the mounting ears are attached), and 12 inches deep (40.7 by 41.8 by 26.4 cm). You can install up to four ONS 15454 shelves in a seven-foot equipment rack. The ONS 15454 must have 1 inch of airspace below the installed unit to allow air flow to the fan intake. If a second ONS 15454 is installed underneath the unit, the air ramp on top of the bottom unit provides the air spacing needed and should not be modified in any way. Figure 1-1 shows the dimensions of the ONS 15454 shelf assembly.

Figure 1-1 Dimensions

1.3.1 Reversible Mounting Bracket


Caution   Use only the fastening hardware provided with the ONS 15454 to prevent loosening, deterioration, and electromechanical corrosion of the hardware and joined material.


Caution   When mounting the ONS 15454 in a frame with a non-conductive coating (such as paint, lacquer, or enamel) either use the thread-forming screws provided with the ONS 15454 shipping kit, or remove the coating from the threads to ensure electrical continuity.

The shelf assembly comes preset for installation in a 23-inch rack, but you can reverse the mounting bracket to fit the smaller, 19-inch rack. The following steps describe how to reverse the shelf assembly mounting bracket to fit a 19- inch rack.

Procedure: Reverse the Mounting Bracket


Step 1 Remove the screws that attach the mounting bracket to the side of the shelf assembly unit.

Step 2 Flip the detached mounting bracket upside down. Text imprinted on the mounting bracket will now also be upside down.

Step 3 Place the widest side of the mounting bracket flush against the shelf assembly.

The narrow side of the mounting bracket should be towards the front of the shelf assembly. Text imprinted on the mounting bracket should be visible and upside down.

Step 4 Align the mounting bracket screw holes against the shelf assembly screw holes.

Step 5 Insert the screws that were removed in Step 1 and tighten them.

Step 6 Repeat the procedure for the mounting bracket on the opposite side.


1.3.2 Mounting the ONS 15454 in a Rack

Mounting the ONS 15454 in a rack requires a minimum of 18.5 inches of vertical rack space (plus 1 inch for air flow). To ensure the mounting is secure, use two to four #12-24 mounting screws for each side of the shelf assembly. Figure 1-2 shows the rack mounting position for the ONS 15454.

Figure 1-2 Rack Mount

Two people should install the ONS 15454 shelf assembly; however, one person can install the shelf assembly using the temporary set screws. Two hex head set screws are included for use when one person is installing the shelf assembly. The shelf should be empty for easier lifting. The door can also be removed to lighten the shelf (see the "Remove the Front Door" section).


Note   If you are installing the fan tray air filter using the brackets provided, mount the brackets on the bottom of the shelf assembly before installing the ONS 15454 in a rack.


Procedure: Mount the Shelf Assembly in a Rack (One Person)


Step 1 Ensure that the shelf assembly is set for the desired rack size (either 19 or 23 inches).

Step 2 Install the set screws using the hex tool that shipped with the assembly.

Step 3 Place the shelf assembly on the set screws using the screw holes that will not be used to mount the shelf.

Step 4 Lift the shelf assembly to the desired rack position.

Step 5 Align the screw holes on the mounting ears with the mounting holes in the rack.

Step 6 Install one mounting screw in each side of the assembly.

At least one set of the ONS 15454's horizontal screw slots should be used to prevent future slippage.

Step 7 When the shelf is secured to the rack, install the remaining mounting screws.

Step 8 Remove the temporary set screws.


Procedure: Mount the Shelf Assembly in a Rack (Two People)


Step 1 Ensure that the shelf assembly is set for the desired rack size (either 19 or 23 inches).

Step 2 Lift the shelf assembly to the desired position in the rack.

Step 3 Align the screw holes on the mounting ears with the mounting holes in the rack.

Step 4 While one person holds the shelf in place, the other person can install one mounting screw in each side of the assembly.

At least one set of the ONS 15454's horizontal screw slots should be used to prevent future slippage.

Step 5 When the shelf is secured to the rack, install the remaining mounting screws.


1.3.3 Multiple Installations in a Rack

Most standard seven-foot racks can hold four ONS 15454s and a fuse and alarm panel. However, unequal flange racks are limited to three ONS 15454s and a fuse and alarm panel or four ONS 15454s when using a fuse and alarm panel from an adjacent rack.


Note   If you are using the bottom brackets to install the fan tray air filter, you can install three shelf assemblies in a standard seven-foot rack. If you are not using the bottom brackets, you can install four shelf assemblies in a rack.


Procedure: Mount Multiple ONS 15454s in a Rack


Step 1 Install the fuse and alarm panel in the top space.

Step 2 Mount the first ONS 15454 unit directly below the fuse and alarm panel.

Step 3 Repeat the procedure with the third and fourth ONS 15454s.


Note   The ONS 15454 must have one inch of airspace below the installed unit to allow air flow to the fan intake. If a second ONS 15454 is installed underneath a unit, the air ramp on top of the bottom unit provides the desired space. However, if the ONS 15454 is installed above third party equipment, you must provide a minimum spacing of one inch between the third party unit and the bottom of the ONS 15454. The third party equipment must not generate heat upward into the ONS 15454.



1.3.3.1 Four Shelf System Example

A common application is linking multiple shelves with a fiber optic bus to accommodate more access traffic than a single shelf can support. For example, if you need to drop more than 112 DS-1s or 96 DS-3s (the maximum that can be aggregated in a single node), you can link the shelves. However, you cannot merge multiple shelves into a single node. You can link shelves with OC-12 or OC-48 fiber spans as you would link any other two network nodes. They can be co-located in a facility to aggregate more local traffic.

Figure 1-3 shows a four shelf system. Each shelf is identified as a separate node in the CTC, and traffic must be mapped using CTC cross-connect options. In the figure, each node uses redundant fiber optic cards. Node 1 uses redundant OC-N transport and OC-N bus cards for a total of four cards, with eight free slots remaining. Nodes 2 and 3 each use two redundant OC-N bus cards for a total of four cards, with eight free slots remaining. Node 4 uses redundant OC-12 bus cards for a total of two cards, with ten free slots remaining. The four shelf system example presented here is one of many ways to set up a multiple-shelf system.

Figure 1-3 Four Shelf System

1.3.3.2 ONS 15454 Bay Assembly

The Cisco ONS 15454 Bay Assembly simplifies ordering and installing the ONS 15454. The ONS 15454 Bay Assembly allows you to order shelf assemblies pre-installed in a seven-foot rack. The Bay Assembly is available in a three- or four-shelf configuration. The three-shelf configuration includes three ONS 15454 shelf assemblies, a pre-wired fuse and alarm panel, and two fiber management trays. Optional fiber channels can be ordered. The four-shelf configuration includes four ONS 15454 shelf assemblies and a pre-wired fuse and alarm panel. Optional fiber channels can be ordered. A four shelf ONS 15454 Bay Assembly is shown in Figure 1-4.

Figure 1-4 Four Shelf ONS 15454 Bay Assembly

1.4 Equipment Access and Features

This section tells you how to access ONS 15454 equipment through the front door and backplane cover and describes the equipment features.


Note   The ONS 15454 has an ESD plug input and is shipped with an ESD wrist strap. The ESD plug input is located on the outside edge of the shelf on the right hand side. It is labeled "ESD" on the top and bottom. Always wear an ESD wrist strap and connect the strap to the ESD plug when working on the ONS 15454.



Note   The front door of the ONS 15454 is grounded to prevent the possibility of electrical shock.


1.4.1 Front Door

The ONS 15454 features a locked door to the front compartment and a screw-in panel over the backplane. A pinned Allen key that unlocks the front door ships with the ONS 15454. A button on the right side of the assembly releases the door. The front door ( Figure 1-5) provides access to the ONS 15454 shelf assembly, cable management tray, fan tray assembly, and LCD screen
( Figure 1-12).

Procedure: Open the Front Cabinet Compartment


Step 1 Open the front door lock.

The ONS 15454 comes with a pinned hex key for locking and unlocking the front door. Turn the key counterclockwise to unlock the door and clockwise to lock it.

Step 2 Press the door button to release the latch.

Step 3 Swing the door open.


Figure 1-5 Front Door

The Critical, Major, and Minor alarm LEDs visible through the front door indicate whether a Critical, Major, or Minor alarm is present anywhere on the ONS 15454. These LEDs must be visible so technicians can quickly determine if any alarms are present. You can use the LCD to further isolate alarms. See the "LCD Alarm Functions" section for more information.

You can remove the front door of the ONS 15454 to provide unrestricted access to the front assembly.

Procedure: Remove the Front Door


Step 1 Open the door.

Step 2 Lift the door from its hinges from the top left corner of the door ( Figure 1-6).


Figure 1-6 Door Hinge

An erasable label ( Figure 1-7) is pasted on the inside of the front door. You can use the label to record slot assignment, port assignments, card types, node ID, rack ID, and serial number for the ONS 15454.

Figure 1-7 Erasable Label on the Inside Door

1.4.2 Card Slots

The ONS 15454 shelf assembly has 17 card slots numbered sequentially from left to right. Slots 1-4 and 14-17 are "multispeed" slots. They can host any ONS 15454 card except the OC-48. Slots 5, 6, 12 and 13 are "high-speed" slots. They can host any ONS 15454 card including OC-48 cards. Slots 7 and 11 are dedicated to timing communications and control (TCC) cards. Slots 8 and 10 are dedicated to cross-connect (XC and XCVT) cards. Slot 9 is reserved for the optional Alarm Interface Controller (AIC) card. Slots 3 and 15 can also host DS1N-14 and DS3N-12 cards that are used in 1:N protection. Each shelf assembly slot has a symbol that indicates the type of cards that can be installed in the slot (see the "Slot Requirements" section for a list).


Caution   Do not operate the ONS 15454 with a single TCC/TCC+ card or a single XC/XCVT card installed. Always operate the shelf assembly with one working and one protect of each type of card.

1.4.3 Cable Management Facilities

The ONS 15454 cable management facilities include the following:

Cable management clips on optical card faceplates

A cable routing channel that runs the width of the shelf assembly

Fiber guides at each side opening of the cable routing channel

The plastic horseshoe-shaped fiber guides ensure that the proper bend radius is maintained in the fibers. You can remove the fiber guide if necessary to create a larger opening (if you need to route copper Ethernet cables out the side, for example). It is removed by taking out the three screws that anchor it to the side of the shelf assembly.

A fold-down door

Cable tie wrap facilities on EIAs

Reversible jumper routing fins

You can route cables out either side by positioning the fins as desired.

Jumper slack storage reels (2) on each side panel

These reels are used to reduce the amount of slack in cables that are connected to other devices. They are easily removed by taking out the screw in the center of each reel.

shows the cable management facilities in the shelf assembly that can be accessed through the fold-down front door of the shelf, including the cable routing channel and the jumper routing fins.

Figure 1-8 Front Panel Cable Management

See the "Cable Management" section for more detailed cable management information.

1.4.4 Fan Tray Assembly

The fan tray assembly is located at the bottom of the ONS 15454 front compartment. The fan tray is a removable drawer that holds fans and fan control circuitry for the ONS 15454. The front door can be left in place when removing or installing the fan tray but removal is recommended. After you install the fan tray, you should only need to access it if a fan failure occurs or you need to replace or clean the fan tray filter.


Note   Install the fan tray filter before installing the fan tray assembly if you are not using the bottom brackets to install the filter on the shelf assembly.


To install or replace the fan tray assembly, it is not necessary to move any of the cable management facilities. You can remove the fan tray assembly using the retractable handles and replace it by pushing until it plugs into the receptacle on the back panel.

The fan tray assembly features an air filter at the bottom of the tray that can be installed and removed by hand. Remove and visually inspect this filter every 30 days. When the filter is dirty, remove the filter and clean it by either vacuuming the filter or running water through it. Because the filter material is delicate, only a very low-power vacuum should be used. If you are cleaning with water, make sure the filter is completely dry before replacing it in the fan tray. Spare filters should be kept in stock.

The shelf assembly ships with a bottom bracket that can be used to install the filter. The bottom bracket consists of two grooved metal pieces that attach to the bottom of the shelf assembly using three screws each. When the fan tray air filter is installed using the bottom bracket, the filter can be installed and removed without first removing the fan tray assembly. The following two procedures describe both methods of filter installation.


Caution   Do not force the fan tray assembly into place when installing a fan tray. Forcing the fan tray assembly into place can damage the connectors on the fan tray and/or the connectors on the back panel of the shelf assembly.

Procedure: Install or Replace the Fan Tray Air Filter Without the Bottom Brackets


Step 1 Remove the fan tray assembly.

If you are replacing the filter, remove the old filter.

Step 2 Slide the filter into the shelf assembly.


Note   You must place the edge of the filter flush against the front of the fan tray assembly compartment when installing the fan tray on top of the filter. Failure to do so could result in damage to the filter, the fan tray, or both.


Although the filter will work if installed with either side facing up, Cisco recommends that you install it with the metal bracing facing up to preserve the surface of the filter.

If the bottom bracket is used to install the fan tray air filter, the fan tray does not need to be removed to access the filter. Attach the brackets to the bottom of the shelf assembly before performing rack installation.


Procedure: Install or Replace the Fan Tray Air Filter Using the Bottom Brackets


Step 1 With the fan tray assembly removed, place the ONS 15454 face down on a flat surface.

Step 2 Locate the three screw holes that run along the left and right sides of the bottom of the shelf assembly.

Step 3 Secure each bracket to the bottom of the shelf assembly using the screws provided.

Each bracket has a filter stopper and a flange on one end. Make sure to attach the brackets with the stoppers and flanges at the rear of the shelf assembly (the top, if the ONS 15454 is face-down during installation).

Figure 1-9 illustrates bottom bracket installation and Figure 1-10 illustrates fan tray filter replacement when bottom brackets are used to install the filter.



Note   If you are using the bottom brackets to install the fan tray air filter, you can install three shelf assemblies in a standard seven-foot rack. If you are not using the bottom brackets, you can install four shelf assemblies in a rack.


Figure 1-9 Bottom Bracket Installation

Figure 1-10 Fan Tray Filter Replacement

Procedure: Install the Fan Tray


Step 1 Remove the front door of the shelf assembly.

Step 2 Slide the fan tray into the shelf until the electrical plug at the rear of the tray plugs into the corresponding receptacle on the backplane.

Step 3 To verify that the tray has plugged into the backplane, check that the LCD on the front of the fan tray is activated.


Procedure: Remove the Fan Tray


Step 1 Remove the front door of the shelf assembly.

Step 2 Fold out the retractable handles at each outside edge of the fan tray.

Step 3 Slide the fan tray out of the shelf by gently pulling on the handles.

Figure 1-11 shows the location of the fan tray. The filter will function no matter which side faces up but Cisco recommends that you install the filter with the metal bracing facing up against the fan tray.


Figure 1-11 Fan Tray Assembly

Fan speed is controlled by Timing Communications and Control (TCC) card temperature sensors. The sensors measure the input air temperature at the fan tray assembly. Fan speed options are low, medium, and high. If the TCC card fails, the fans automatically shift to high speed. The temperature measured by the TCC sensors is displayed on the LCD screen.

If one or more fans fail on the fan tray assembly, replace the entire assembly. You cannot replace individual fans. The red Fan Fail LED on the front of the fan tray illuminates when one or more fans fail. For fan tray replacement instructions, see the "Install the Fan Tray" section. The red Fan Fail LED clears after you install a working fan tray.

1.4.5 LCD Screen

The ONS 15454 LCD screen provides port-level information for all ONS 15454 card slots.

You can set the IP address, subnet mask, and default router for the node by using the LCD screen. This allows you to accomplish these basic operations without a computer. For instructions about using the LCD screen to set these parameters, see the "Enter IP Address Using Front Panel LCD" section on page 8-10.

Press the Slot, Port, or Status buttons to display status information for each ONS 15454 slot and port. The LCD displays the number of Critical, Major, and Minor alarms on a slot or port basis.

Procedure: View Alarms Counts on a Specific Slot and Port


Step 1 Use the Slot button to toggle to the desired slot number.

Set the slot number to Slot 0 to see a summary of alarms for the node.

Step 2 Use the Port button to toggle to the port.

Step 3 Use the Status button to toggle through all active alarms and conditions.

Figure 1-12 shows the LCD panel.

Figure 1-12 LCD Panel

By default, the LCD screen displays the ONS 15454 network element IP address. The Cisco Transport Controller needs this address to access the ONS 15454.

The LCD panel alternately displays the node name and the current date. The IP address alternates with the current software version on the LCD; the time and temperature also display alternately.

The information displayed on the LCD is determined by the software version you are currently running.


Caution   If the ONS 15454 node connects to a LAN, change the default ONS 15454 IP address to an address that is compatible with the network. If you do not change the IP address, the network can be disrupted. For IP addressing procedures, see the "Setup a PC for Direct Connection" section on page 3-5.


1.4.6 LCD Alarm Functions


Note   The Critical, Major and Minor alarm LEDs on the fan tray front panel indicate whether a critical, major, or minor alarm is present anywhere on the ONS 15454 assembly. These LEDs are viewable through the front door so that you can quickly determine if any alarms are present on the assembly. These LEDs are independent of the Card, Port, and Status indicators on the LCD. You can view specific alarm messages in the Alarms menu in the CTC.


When you press the Slot, Port, or Status buttons, the LCD displays the selected slot and port and the number of Critical, Major, or Minor alarms.

See Chapter 2, "Card Reference," for descriptions of the port-level states supported by ONS 15454 cards.

1.4.7 Backplane Covers

To access the ONS 15454 backplane, remove the sheet metal on each side of the backplane
( Figure 1-13). Each sheet metal panel is held in place with nine 6-32 x 3/8 inch Phillips screws.

Figure 1-13 Backplane Sheet Metal Covers

Before installing EIA(s), you need to prepare the backplane by removing the backplane sheet metal covers to expose the EIA backplane mating connectors.

Procedure: Remove the Backplane Sheet Metal Covers


Step 1 To remove the lower backplane cover, loosen the five screws that secure it to the ONS 15454 and pull it away from the shelf assembly.

Step 2 Loosen the nine perimeter screws that hold the backplane sheet metal cover(s) in place.

Step 3 Lift the panel by the bottom to remove it from the shelf assembly.

Step 4 Store the panel for later use. Attach the backplane sheet metal cover(s) whenever EIA(s) are not installed.

Figure 1-13 shows the sheet metal covers on the ONS 15454 backplane.


1.4.7.1 EIA Backplane Cover (Optional)

EIAs are typically pre-installed on the ONS 15454 when ordered with the system. EIAs must be ordered when using DS-1, DS-3, DS3XM-6, or EC-1 cards. Four different EIAs are available for the ONS 15454: BNC, High-density BNC, SMB, and AMP CHAMP. This section describes each EIA in detail.

EIAs host a special card that provides coaxial cable connection points (SMB or BNC) for the DS-3 or EC-1 cards. EIAs also host twisted pair wire-wrap adapters for SMB connectors or, for the DS-1 card, AMP CHAMP connectors. EIAs also feature a special backplane cover with cutouts over the cable connectors. You can install EIAs on one or both sides of the ONS 15454 backplane in any combination (in other words, AMP Champ on Side A and BNC on Side B or High-density BNC on side A and SMB on side B, and so forth).

If you are installing EIAs after the ONS 15454 shelf assembly is installed, plug the EIA card into the backplane. The EIA has six electrical connectors that plug into six corresponding backplane connectors. The EIA must replace the standard sheet metal cover to provide access via the coaxial cable connectors. The EIA sheet metal covers use the same screw holes as the solid backplane panels, but they have 12 additional 6-32 x 1/2 inch Phillips screw holes so you can screw down the cover and the card using standoffs on the EIA card. For information about installing EIAs, see the "Install an EIA" section. To view a list of EIAs and their functions, see Table 10-1 on page 10-13.

1.4.7.2 BNC EIA

The ONS 15454 BNC EIA supports Trompeter UCBJ224 75 Ohm 4 leg connectors. You can use BNC EIAs for DS-3 (including the DS3XM-6) or EC-1 cards. Figure 1-14 shows the ONS 15454 with pre-installed BNC EIAs.

For instructions on installing coaxial cable with BNC connectors, see the "BNC Installation" section.

Figure 1-14 BNC Backplane

Step 1 Unscrew the five retaining screws that hold the Plexiglas cover in place.

Step 2 Grasp the Plexiglas cover at each side.

Step 3 Gently pull the cover away from the backplane (shown in Figure 1-18).


1.4.7.7 Alarm Interface Panel

The Alarm Interface Panel (AIP) is located above the alarm pin field on the lower section of the backplane (see the "Equipment Access and Features" section for information about how to access the AIP). The AIP provides surge protection for the ONS 15454 shelf assembly. It also provides an interface from the backplane to the fan tray assembly and LCD. The AIP plugs into the backplane using a 96 pin DIN connector and is held in place with two retaining screws. The panel has a non-volatile memory chip that stores the unique node (MAC) address.

The MAC address identifies the nodes that support circuits. It allows the CTC to determine circuit sources, destinations, and spans. The TCC cards in the ONS 15454 also read the MAC address to store the node database. You can change the default IP address in CTC. See the "Set Up Network Information" section on page 3-23 for instructions.

If the AIP fails, a MAC Fail alarm displays on the CTC Alarms menu. See the "Viewing ONS 15454 Alarms" section on page 3-18 for more information about alarms.

Step 8 Replace the screws that secure the panel to the backplane.

Step 9 Reset both TCCs, one at a time.


1.5 Power and Ground Installation

This section explains how to connect the ONS 15454 assembly to the power supply.


Warning   Shut off the power from the power source before beginning work.



Warning   Always use the supplied electrostatic discharge wristband when working with a powered ONS 15454. Plug the wristband cable into the ESD jack located on the lower-right outside edge of the shelf assembly.



Warning   Do not mix conductors of dissimilar metals in a terminal or splicing connector where physical contact occurs (such as copper and aluminum, or copper and copper-clad aluminum), unless the device is suited for the purpose and conditions of use.



Warning   Connect the ONS 15454 only to a DC power source that complies with the safety extra-low voltage (SELV) requirements in IEC 60950-based safety standards


Use the following wiring conventions:

Red wire for battery connections (-48V DC)

Black wire for battery return connections (0V DC)


Note   Use an external disconnect (minimum 15A fused) for service purposes. Install according to local site practice.


The ONS 15454 has redundant -48V DC #8 power terminals on the assembly backplane. The terminals are labeled BAT1, RET1, BAT2, and RET2 and are located on the lower section of the backplane behind a Plexiglas cover. See the "Equipment Access and Features" section for information about accessing the power terminals.

To install redundant power feeds, use four power cables and one ground cable. For a single power feed, only two power cables and one ground cable are required. Use #12 or #14 AWG cable. Use a conductor with low impedance to ensure circuit overcurrent protection. However, the conductor must have the capability to safely conduct any fault current that might be imposed.


Warning   When installing redundant power feeds, do not use aluminum conductors.



Warning   If you use redundant power leads to power the ONS 15454, disconnecting one lead will not remove power from the shelf.


Procedure: Install Redundant Power Feeds


Step 1 Measure and cut the cables as needed to reach the ONS 15454 from the fuse panel. Use 15A fuses for each power lead. Figure 1-19 shows the ONS 15454 power terminals.

Step 2 Dress the power and ground cables according to local site practice.


Warning   When installing the ONS 15454, the ground connection must always be made first and disconnected last.


Step 3 Remove or loosen the #8 power terminal screws on the ONS 15454. To avoid confusion, label the cables connected to the BAT1/RET1 power terminals as 1, and the cables connected to the BAT2/RET2 power terminals as 2.


Note   Use only listed compression type connectors when terminating the battery, battery return, and frame ground conductors.



Caution   Before you make any crimp connections, coat all bare conductors (battery, battery return, and frame ground) with an appropriate antioxidant compound. Bring all unplated connectors, braided strap, and bus bars to a bright finish, then coat with an antioxidant before you connect them. You do not need to prepare tinned, solder plated, or silver-plated connectors and other plated connection surfaces, but always keep them clean and free of contaminants.


Caution   When terminating power, return, and frame ground, do not use soldering lug, screwless (push-in) connectors, quick-connect, or other friction-fit connectors.

Step 4 Strip 1/2 inch of insulation from all power cables that you will use. If you are using lugs, crimp the lugs onto the ends of all power leads.


Note   When terminating battery and battery return connections as shown in , follow a torque specification of 10 in-lbs. When terminating a frame ground, use the kep-nut provided with the ONS 15454 and tighten it to a torque specification of 31 in-lbs. The kep-nut provides a frame ground connection that minimizes the possibility of loosening caused by rotation during installation and maintenance activity. This type of prevention is inherently provided by the terminal block for battery and battery return connections.


Step 5 Terminate the return 1 lead to the RET1 backplane terminal. Use oxidation prevention grease to keep connections non-corrosive.


Warning   Do not secure multiple connectors with the same bolt assembly.


Step 6 Terminate the negative 1 lead to the negative BAT1 backplane power terminal. Use oxidation prevention grease to keep connections non-corrosive.

Step 7 If you use redundant power leads, terminate the return 2 lead to the positive RET terminal on the ONS 15454. Terminate the negative 2 lead to the negative BAT2 terminal on the ONS 15454. Use oxidation-preventative grease to keep connections non-corrosive.

Step 8 Route the cables out using the plastic cable clamp below the power terminals.


Figure 1-19 Power Terminals


Warning   When installing the ONS 15454, the ground connection must always be made first and disconnected last.


You only ground one cable to ground the assembly. Terminate the other end of the rack ground cable to ground according to local site practice. The ONS 15454 backplane also has a ground terminal on the right side of the backplane. Connect a ground terminal for the frame ground (FGND) terminal according to local site practice.

If the system loses power or both TCC cards are reset, you must reset the ONS 15454 clock. After powering down, the date defaults to January 1, 1970, 00:04:15.


Warning   Do not apply power to the ONS 15454 until you complete all installation steps.


1.6 Alarm Pin Field Connections


Caution   Always use the supplied electrostatic discharge wristband when working with a powered ONS 15454. Plug the wristband cable into the ESD jack located on the lower-right outside edge of the shelf assembly.

The ONS 15454 backplane has an alarm pin field located at the bottom of the backplane. The alarm pin field provides 0.045 square inch wire-wrap pins for installing external alarms, timing input and output, and craft interface terminals. This section describes the alarm pin field and the pin assignments for the field. Figure 1-20 shows the wire-wrap pins on the alarm pin field. Beneath each wire-wrap pin is a frame ground pin. Frame ground pins are labeled FG1, FG2, FG3, etc. Install the ground shield of the cables connected to the backplane to the ground pin that corresponds to the pin field used. Figure 1-20 shows pinouts for the ONS 15454.

See the "Equipment Access and Features" section for information about how to access the alarm pin field.

Figure 1-20 Pinouts

1.6.1 Alarm Installation

The alarm pin field supports up to 17 alarm contacts: four audible alarms, four visual alarms, one Alarm Cutoff (ACO), and four user-definable alarm inputs and outputs. Audible alarm contacts are in the LOCAL ALARM AUD pin field. Visual contacts are in the LOCAL ALARM VIS pin field. Both of these types of alarms fall into the LOCAL ALARMS category. User-definable contacts are in the ENVIR ALARM IN and ENVIR ALARM OUT pin fields. These two types of alarms fall into the ENVIR ALARMS category; you must have the AIC card installed in order to use the ENVIR ALARMS. The MODEM and X.25 pin fields are not currently used. Alarm contacts are Normally Open (N/O), meaning that the system closes the alarm contacts when the corresponding alarm conditions are present. Each alarm contact consists of two wire-wrap pins on the assembly backplane. The alarm contacts are wired to the TCC card through the ONS 15454 backplane. Visual and Audible alarm contacts are classified as Critical, Major, Minor, and Remote. Refer to for alarm pin assignments.

Visual and audible alarms are typically wired to trigger an alarm light at a central alarm collection point when the corresponding contacts are closed. You can use the Alarm Cutoff pins to activate a remote ACO for audible alarms. You can also activate the ACO function by pressing the ACO button on the TCC card faceplate. The ACO function clears all audible alarm indications. After clearing the audible alarm indication, the alarm is still present and viewable in the Alarms tab in CTC.

To install alarm wires on the backplane, use #22 or #24 AWG alarm wires. Wrap the alarm wires on the appropriate wire-wrap pins according to local site practice. Each pin field has a frame ground pin beneath it.

1.6.2 Timing Installation

The ONS 15454 backplane supports two Building Integrated Timing Supply (BITS) clock pin fields. The first four BITS pins, rows 3 and 4, support output and input from the first external timing device. The last four BITS pins, rows 1 and 2, perform the identical functions for the second external timing device. lists the pin assignments for the BITS timing pin fields.

* When used as a protect card, the card does not have a physical external connection. The protect card connects to the working card(s) through the backplane and becomes active when the working card fails. The protect card then uses the physical connection of the failed card.

1.8.2 Card Turn-Up

The procedure for turning up ONS 15454 cards is nearly identical for each card. AIC card turn-up is slightly different from all other cards and is described in its own procedure, and the XC/XCVT and TCC/TCC+ turn up procedures are virtually identical and are described in one procedure. Turn up for all other cards is the same and is covered by one procedure.


Note   Because all other cards boot from the active TCC/TCC+ card, at least one TCC/TCC+ card must be installed in order to boot any other cards.


Procedure: Verify Successful Turn-Up of the AIC Card


Step 1 Install the card in the correct slot.

Step 2 Verify that power is applied to the shelf assembly.

Step 3 Verify that the red FAIL LED blinks for 30 to 45 seconds.

Step 4 Verify that after 30 to 45 seconds, all LEDs blink once and turn off.

Step 5 Verify that the ACT LED is on.

Step 6 Verify that the card appears in the correct slot on the CTC software screen.

Step 7 Verify that the card is white on the CTC software screen.


Procedure: Verify Successful Turn-Up of the TCC/TCC+ and XC/XCVT Cards


Step 1 Install the card in the correct slot (Slot 8 or 10 for the XC/XCVT and slot 7 or 11 for the TCC/TCC+).

Step 2 Verify that power is applied to the shelf assembly.

Step 3 Verify that the red FAIL LED blinks for 30 to 45 seconds.

If the FAIL LED is displayed continuously on the TCC/TCC+ card, see the note below concerning TCC/TCC+ uploading.

Step 4 Verify that after 30 to 45 seconds, all LEDs blink once and turn off.

Step 5 Verify that the ACT/STBY LED is the correct color for the card (green for active, yellow for standby).

On the TCC/TCC+ card, the LED may take several minutes to illuminate while the DCC processor boots.

Step 6 Verify that the card appears in white in the correct slot on the CTC software screen.


Note   This is not the procedure to use when upgrading from XC to XCVT cards. If you are performing an XC to XCVT upgrade, see the "Upgrade XC Cards to XCVT" section. If you are performing a TCC to TCC+ upgrade, see the "TCC Card to TCC+ Card Upgrade" section on page 10-11.




Tip When a TCC/TCC+ card installed in the shelf assembly has a different version of the ONS 15454 software installed than the version running on the active TCC/TCC+, it automatically loads the software version running on the active TCC/TCC+. You do not need to do anything in this situation. However, the loading TCC/TCC+ card will not boot up in the normal manner. When the card is first inserted, the red FAIL LED stays on for a short period. The FAIL LED then blinks as normal after which all LEDs go dark. The FAIL LED and the ACT/STBY LED flash alternately every 30 to 45 seconds as the new software loads onto the new TCC/TCC+ card. After loading the new software for approximately 30 minutes, the TCC/TCC+ card becomes the standby card and the amber LED is illuminated.



Warning   Follow all directions and warning labels when working with optical fibers. To prevent eye damage, never look directly into a fiber or connector.


Procedure: Verify Successful Turn-Up of All Other Cards


Step 1 Install the card in the correct slot.

Step 2 Verify that power is applied to the shelf assembly.

Step 3 Verify that the red FAIL LED blinks for 30 to 45 seconds.

Step 4 Verify that after 30 to 45 seconds, all LEDs blink once and turn off.

Step 5 Verify that the ACT LED is on. Note that the signal fail (SF) LED may persist until all card ports connect to their far end counterparts and signal is present.

Step 6 Verify that the card appears in the correct slot on the CTC software screen.

Step 7 Verify that the card is white on the CTC software screen.


1.8.3 Card Software Installation

After you install an ONS 15454 card in a valid card slot, the card's software automatically updates to the version that operates correctly with the system software installed on the TCC. To verify the current version of software installed on the XTC, click the Help menu and then click About CTC. See "" for more information.

1.8.4 Gigabit Interface Converter

GBICs are hot-swappable input/output devices that plug into a Gigabit Ethernet port to link the port with the fiber optic network. Cisco provides two GBIC models: one for short reach applications (part number 15454-GBIC-SX) and one for long-reach applications (15454-GBIC-LX). The short reach, or "SX" model, connects to multimode fiber and the long reach, or "LX" model, requires single- mode fiber. Because the GBICs are very similar in appearance, check the label on the GBIC carefully before installing it. A GBIC is shown in .

Figure 1-27 Gigabit Interface Converter

shows the available GBICs.

The 15454-GBIC-SX operates on ordinary multi-mode fiber optic link spans of up to 550 m in length.

15454-GBIC-LX

The 15454-GBIC-LX fully complies with the IEEE 802.3z 1000BaseLX standard. However, their higher optical quality allows them to reach 10km over single-mode fiber (SMF) versus the 5 km specified in the standard.

Procedure: Install Gigabit Interface Converters


Step 1 Remove the GBIC from its protective packaging.

Step 2 Check the part number to verify that the GBIC is the correct type for your network.

Step 3 Grip the sides of the GBIC with your thumb and forefinger and insert it into the slot on the front panel of the Gigabit Ethernet card (shown in ).

GBICs are hot-swappable and can therefore be installed/removed while the card/shelf assembly is powered and running.


Note   GBICs are keyed to prevent incorrect installation.


Figure 1-28 GBIC Installation

Step 4 Slide the GBIC through the flap that is covering the opening until you hear a click.

The click indicates the GBIC is locked into the slot.


Warning   GBICs are Class 1 laser products. These products have been tested and comply with
Class 1 limits.



Warning   Invisible laser radiation may be emitted from the aperture ports of the single-mode fiber optic modules when no cable is connected. Avoid exposure and do not stare into open apertures.


Step 5 When you are ready to attach the network interface fiber optic cable, remove the plug from the GBIC and save the plug for future use.


Procedure: Remove a Gigabit Interface Converter


Step 1 Disconnect the network fiber cable from the GBIC SC connector.

Step 2 Release the GBIC from the slot by simultaneously squeezing the two plastic tabs (one on each side of the GBIC).

Step 3 Slide the GBIC out of the Gigabit Ethernet module slot.

A flap closes over the GBIC slot to protect the connector on the Gigabit Ethernet card.



Warning   Ultimate disposal of this product should be handled according to all national laws and regulations.


1.9 Cable Installation

This section explains how to install fiber, coaxial, and DS-1 cables.

1.9.1 Fiber Cable Installation


Caution   Always use the supplied electrostatic discharge wristband when working with a powered ONS 15454. Plug the wristband cable into the ESD jack located on the lower-right outside edge of the shelf assembly.

ONS 15454 fiber optic cards feature SC connectors. To install fiber optic cables in the ONS 15454, a fiber cable with the corresponding connector type must be connected to the transmit and receive ports on the ONS 15454 cards. On ONS 15454 optical card ports, the top connector is Transmit and the bottom connector is Receive. Cisco recommends that the transmit and receive and the working and protection fibers be labeled at each end of the fiber span to avoid confusion with cables that are similar in appearance.


Warning   Follow all directions and warning labels when working with optical fibers. To prevent eye damage, never look directly into a fiber or connector.


Procedure: Install and Route Fiber Optic Cables in the ONS 15454


Step 1 Place the SC connector in front of the connection point on the card faceplate. Each card supports at least one transmit and one receive connector to create an optical carrier port. Figure 1-29 shows the cable location.

Figure 1-29 Fiber Cable Connection

Step 2 Align the keyed ridge of the cable connector with the receiving slot on the faceplate connection point.

Step 3 Gently push the cable connector into the faceplate connection point until the connector snaps into place.

Step 4 Route fiber cables through the cable retaining clips on the optical card faceplate into the cable management tray on the bottom of the assembly.

Step 5 From the cable management tray, route the fiber cables out the nearest side of the assembly through cutout holes.


See the "Cable Management Facilities" section for more information about cable management.


Note   Clean all fiber connectors thoroughly. Dust particles can degrade performance. Put caps on any fiber connectors that are not used.


Cisco provides clear plastic fiber boots for each optics card. The boots prevent hanging fibers from bending too sharply, which may degrade performance. The boots also prevent the front door from interfering with hanging fibers. Figure 1-30 shows the fiber boot attachment.

Figure 1-30 Fiber Boot Attachment

You can install the fiber boots on the fiber optic cables before or after the fibers are attached to the optic card.

Procedure: Install the Fiber Boot


Step 1 Position the open slot of the fiber boot underneath the fiber cable.

Step 2 Push the fiber cable down into the fiber boot.

Step 3 Twist the fiber boot to lock the fiber cable into the tail end of the fiber boot.

Step 4 Slide the fiber boot forward along the fiber cable until the fiber boot fits snugly onto the end of the SC cable connector.


1.9.2 Coaxial Cable Installation


Caution   Always use the supplied electrostatic discharge wristband when working with a powered ONS 15454. Plug the wristband cable into the ESD jack located on the lower-right outside edge of the shelf assembly.

When using ONS 15454 DS-3 electrical cables, the cables must terminate on a pre-installed EIA on the ONS 15454 backplane. EIAs are available with SMB and BNC type connectors. All DS-3 cables connected to the ONS 15454 DS-3 card must terminate with coaxial cables using the desired connector type in order to connect to the specified EIA. For information about physically installing an EIA in the field, see the "Backplane Covers" section.

1.9.2.1 BNC Installation

When EIAs are pre-installed on the backplane, a special backplane cover panel with cutouts over the coaxial cable connectors is provided. The BNC EIA supports 24 DS-3 circuits on each side of the ONS 15454 (24 transmit and 24 receive connectors). If you install BNC EIAs on both sides of the unit, the ONS 15454 hosts up to 48 circuits. The BNC connectors on the EIA are Trompeter UCBJ224 (75 Ohm) 4 leg connectors. Right angle mating connectors for the connecting cable are AMP 413588-2 (75 Ohm) connectors. A straight connector of the same type can also be used, if preferred. Use RG-59/U cable to connect to the ONS 15454 BNC EIA. These cables are recommended to connect to a patch panel and are designed for long runs of up to 450 feet.

Procedure: Install Coaxial Cable With BNC Connectors


Step 1 Place the BNC cable connector over the desired connection point on the backplane.

Figure 1-31 shows how to connect a coaxial cable to the BNC EIA using a right-angle BNC cable connector.

Step 2 Position the cable connector so that the slot in the connector is over the corresponding notch at the backplane connection point.

Step 3 Gently push the connector down until the notch backplane connector slides into the slot on the cable connector.

Step 4 Turn the cable connector until the notch clicks into place.

Step 5 Tie wrap the cables to the EIA according to local site practice.

Step 6 Route the cables to the nearest side of the shelf assembly through the side cutouts according to local site practice. The rubber coated edges of the side cutouts prevent the cables from chafing.


Figure 1-31 BNC Backplane Connection Using a Right Angle Connector


Note   Slots 1, 3, 15 and 17 are designated protection slots when BNC connectors are used. Slots 5, 6, 11, and 12 do not support DS3-12 cards when BNC connectors are used. A total of four DS3-12 cards may be used to carry traffic when BNC connectors are used.


Label all cables at each end of the connection to avoid confusion with cables that are similar in appearance.

1.9.2.2 High-Density BNC Installation

The High-density BNC EIA supports 48 DS-3 circuits on each side of the ONS 15454 (48 transmit and 48 receive connectors). If you install BNC EIAs on both sides of the unit, the ONS 15454 hosts up to 96 circuits. You must use straight connectors on RG-59/U cable to connect to the ONS 15454 High-density BNC EIA. Cisco recommends these cables for connection to a patch panel; they are designed for long runs of up to 450 feet.

Although not required, Cisco strongly recommends using the BNC insertion tool to connect cables to the EIA. See page 10- 15 for more information about the insertion tool.

Procedure: Install Coaxial Cable With High-density BNC Connectors


Step 1 Place the BNC cable connector over the desired connection point on the backplane.

Step 2 Using the insertions tool, position the cable connector so that the slot in the connector is over the corresponding notch at the backplane connection point.

Step 3 Gently push the connector down until the notch backplane connector slides into the slot on the cable connector.

Step 4 Turn the cable connector until the notch clicks into place.

Step 5 Tie wrap the cables to the EIA according to local site practice.

Step 6 Route the cables to the nearest side of the shelf assembly through the side cutouts according to local site practice.

The rubber coated edges of the side cutouts prevent the cables from chafing.


1.9.2.3 SMB Installation

The SMB backplane cover is similar to the BNC cover. The SMB EIA has 84 transmit and 84 receive connectors on each side of the ONS 15454 for a total of 168 SMB connectors (84 circuits). For DS-3 or EC-1, the EIA supports 72 transmit and 72 receive connectors, for a total of 144 SMB connectors (72 circuits.) The SMB connectors on the EIA are AMP 415504-3 (75 Ohm) 4 leg connectors. Right- angle mating connectors for the connecting cable are AMP 415484-2 (75 Ohm) connectors. Use RG-179/U cable to connect to the ONS 15454 EIA. Cisco recommends these cables for connection to a patch panel; they are not designed for long runs.

Procedure: Install SMB Type Connectors

Refer to Figure 1-32 when performing the following steps.


Step 1 Place the SMB cable connector over the desired connection point on the backplane.

Step 2 Gently push the connector until it clicks into place.

Step 3 Tie wrap the cables to the EIA according to local site practice.

Step 4 Route the cables to the nearest side of the shelf assembly into rack runs according to local site practice.


Figure 1-32 SMB Coaxial Cable Connections

Label the transmit, receive, working and protection cables at each end of the connection to avoid confusion with cables that are similar in appearance.

1.9.3 DS-1 Cable Installation

DS-1s support both twisted pair wire-wrap cabling and AMP CHAMP connector cabling. Install the proper backplane EIA on the ONS 15454 for each cabling option. This section provides information about the DS-1 EIA options.

1.9.3.1 Twisted Pair Wire Wrap Installation

Installing twisted-pair, wire-wrap DS-1 cables requires separate pairs of grounded twisted-pair cables for receive (in) and transmit (out). Prepare four cables, two for receive and two for transmit, for each DS-1 facility to be installed.


Caution   Always use the supplied electrostatic discharge wristband when working with a powered ONS 15454. Plug the wristband cable into the ESD jack located on the lower-right outside edge of the shelf assembly.

If you use DS-1 electrical twisted pair cables, equip the ONS 15454 with an SMB-based EIA on each side of the backplane where DS-1 cables will terminate. You must install special DS-1 electrical interface adapters on every transmit and receive connector for each DS-1 termination. See the "Install DS-1 Electrical Interface Adapters" section for information about installing SMB backplane covers.


Note   DS-1 electrical interface adapters project an additional 1.72 inches from the ONS 15454 backplane.


EIAs are special cards attached to the assembly backplane that provide cable connectors and a cover panel that features cutouts over the coaxial cable connectors. EIAs are available with SMB and BNC type connectors. You must use SMB EIAs for DS-1 twisted-pair cable installation.

If you install DS-1 cards in the ONS 15454, you must fit the corresponding transmit and receive SMB connectors on the EIA with a DS-1 electrical interface adapter. You can install the adapter on the SMB connector for the port. The adaptor has wire wrap posts for DS-1 transmit and receive cables. Figure 1-33 shows the DS-1 electrical interface adapter.

Figure 1-33 Electrical Interface Adapter

Each DS-1 electrical interface adapter, commonly referred to as a balun, has a female SMB connector on one end and a pair of .045 inch square wire wrap posts on the other end. The wire wrap posts are .200 inches apart.

Procedure: Install DS-1 Electrical Interface Adapters


Step 1 Attach the SMB connector on the adapter to the SMB connector for the port's transmit pair on the backplane.

Step 2 Attach the SMB connector on an adapter to the SMB connector for the port's receive pair on the backplane.

Step 3 Terminate the DS-1 transmit and receive cables for the port to the wire wrap posts on the adapter.

Make sure to install the electrical interface adapter with the wire wrap posts.

If you place DS1N-14 in Slots 3 and 15 to form 1:N protection groups, do not wire Slots 3 and 15 for DS-1 electrical interface adapters.

Figure 1-34 shows a ONS 15454 backplane with an SMB EIA with DS-1 electrical interface adapters attached on both sides of the shelf to create DS-1 twisted pair termination points.


Figure 1-34 Backplane With SMB EIA

All DS-1 cables connected to the ONS 15454 DS-1 ports must terminate with twisted-pair cables to connect to the DS-1 electrical interface adapter. The DS-1 electrical interface adapters project 1.72 inches beyond the SMB EIA.

Procedure: Install DS-1 Cables on the DS-1 Electrical Interface Adapters


Step 1 Using a wire-wrap tool, connect the receive cables to the receive adapter pins on the backplane connector for the desired port.

Step 2 Connect the transmit cables to the transmit adapter pins on the backplane connector for the desired port.

Step 3 Terminate the shield ground wire on the DS-1 cable to ground according to local site practice.

Step 4 If you place DS1N-14 cards in Slots 3 and 15 to form 1:N protection groups, do not wire Slots 3 and 15 for DS-1 electrical interface adapters.


1.9.3.2 AMP CHAMP Installation

To instal AMP CHAMP connector DS-1 cables you must use 64-pin bundled cable connectors with a 64-pin male AMP CHAMP connector. You need an AMP CHAMP connector #552276-1 for the receptacle side and #1-552496-1 for the right angle shell housing (or their functional equivalent). The corresponding 64-pin female AMP CHAMP connector on the AMP CHAMP EIA supports one receive (in) and one transmit (out) for each DS-1 port for the corresponding card slot.

Because each DS1-14 card supports 14 DS-1 ports, only 56 pins (28 pairs) of the 64-pin connector are used. Prepare one 56-wire cable for each DS-1 facility installed. shows the pin assignments for the AMP CHAMP connectors on the ONS 15454 AMP CHAMP EIA. See the "AMP CHAMP EIA" section for more information about the AMP CHAMP EIA.

Caution   Always use the supplied electrostatic discharge wristband when working with a powered ONS 15454. Plug the wristband cable into the ESD jack located on the lower-right outside edge of the shelf assembly.

When using DS-1 AMP CHAMP cables, you must equip the ONS 15454 with an AMP CHAMP connector EIA on each side of the backplane where DS-1 cables will terminate. Each AMP CHAMP connector on the EIA corresponds to a slot in the shelf assembly and is numbered accordingly. The AMP CHAMP connectors have screw-down tooling at each end of the connector. See the "AMP CHAMP EIA" section for information on AMP CHAMP backplane cover installation.

Procedure: Install DS-1 AMP CHAMP Cables on the AMP CHAMP EIA


Step 1 Prepare a 56-wire cable for each DS-1 card you will install in the shelf assembly. See for the ONS 15454 AMP CHAMP connector pin assignments.

Step 2 Connect the male AMP CHAMP connector on the cable to the female AMP CHAMP connector on the ONS 15454 backplane.

Step 3 Use the clips on the male AMP CHAMP connector to secure the connection.

The female connector has grooves on the outside edge for snapping the clips into place.


1.10 Cable Management

ONS 15454 cable management components include cable management clips on the optical card faceplates, a cable management tray in the front cabinet compartment, and cable tiewrap facilities on the EIAs.

1.10.1 Optical Cable Management

Optical cables connect to the SC connectors on the faceplate of the optical cards as described in the "Fiber Cable Installation" section. Route optical cables down through the fiber management clips on the optical card faceplate (shown in Figure 1-35).

Route optical cables from the fiber management clips into the cable management area of the shelf assembly, through a cutout in the nearest side of the assembly, and onto the side of the assembly. A hinged panel on the front of the shelf assembly folds down to provide access to the cable management tray. Figure 1-36 shows the fold-down panel and cable management tray.

Figure 1-35 Cable Routing

Procedure: Route Optical Cables in the Shelf Assembly


Step 1 Open the fold-down front door on the fiber management tray.

Step 2 Route the cable on the card faceplate through the fiber clip on the faceplate.

Step 3 Route the cables into the cable management tray.

Step 4 Route the cables out either side of the cable management tray through the cutouts on each side of the shelf assembly. Use the reversible fiber guides to route cables out the desired side.

Step 5 Close the fold-down front door when all cables in the front compartment are properly routed.


shows the fold-down front door of the shelf assembly open to display the cable routing channel.

Figure 1-36 Fold-down Front Door of the Shelf Assembly

1.10.2 Coaxial Cable Management

Coaxial cables connect to the BNC type or SMB type EIAs on the ONS 15454 backplane using cable connectors. The BNC type EIAs support up to 48 transmit and receive coaxial connectors on each side of the ONS 15454 backplane for a total of up to 96 connectors (48 circuits). The SMB type EIAs support up to 84 transmit and receive coaxial connectors on each side of the ONS 15454 for a total of up to 168 connectors (84 circuits).

When EIAs are used, the backplane cover uses cutouts over the cable connectors. Incoming cables terminated with the corresponding connector type (SMB or BNC) can be connected directly onto the backplane through the cover cutouts.

EIAs feature cable management eyelets for tie wrapping or lacing cables to the cover panel. Tiewrap or lace the coaxial cables according to local site practice and route the cables through the side cutouts on either side of the ONS 15454 assembly. The rubber coated edges of the side cutouts prevent the cables from chafing.

When using the RG179 cable with SMB connectors, remember that the maximum distance available with the RG179 cable is less than the maximum distance available with standard RG59 cable. If you only use the RG179, the maximum available distance is 100 feet versus the 450 feet available with the larger RG59 cable.

Use short lengths of "pigtail" RG179 to terminate the shelf, and use standard RG59 connected to the RG179 for the remainder of the cable run. When using a 10-foot section of the RG179, you can attach a maximum length of 437 feet of RG59. When using a 30-foot section of RG179, you can attach a maximum length of 311 feet of RG59.

The shorter maximum distance available with the RG179 is due to a higher attenuation rate for the thinner cable. The attenuation rate for RG59 cable (based on testing with Belden 923, the equivalent of 328A cable) is ~1.0 dB/100 feet at 22 Mhz (DS-3 data rate). The attenuation rate of RG179 is
6.3 db/100 feet. Use a figure of 5.0 for total cable loss when making calculations. Figure 1-37 shows one side of the ONS 15454 backplane with SMB EIAs and the coaxial cables properly routed.

Figure 1-37 Backplane Cable Routing

1.10.3 Twisted Pair Cable Management

Connect twisted pair/DS-1cables to SMB EIAs on the ONS 15454 backplane using cable connectors and DS-1 electrical interface adapters. The SMB type EIAs support up to 84 transmit and receive SMB connectors on each side of the ONS 15454 for a total of up to 168 connectors (84 circuits).

When using DS-1 twisted pair cables, the backplane cover features cutouts over the SMB cable connectors. You must install DS-1 electrical interface adapters on every transmit and receive connector for DS-1 ports. Incoming cables terminated can be connected directly onto the backplane using the wire wrap posts on the DS-1 electrical interface adapters.

SMB EIAs feature cable management eyelets for tie wrapping or lacing cables to the cover panel. Tie wrap or lace the twisted pair cables according to local site practice and route the cables into the side cutouts on either side of the ONS 15454 assembly.

1.10.4 AMP CHAMP Cable Management

AMP CHAMP cables connect to the EIAs on the ONS 15454 backplane using AMP CHAMP cable connectors. The AMP CHAMP EIAs support up to six AMP CHAMP connectors on each side of the ONS 15454 backplane for a total of up to 12 connectors.

EIAs have cable management eyelets to tiewrap or lace cables to the cover panel. Tiewrap or lace the AMP CHAMP cables according to local site practice and route the cables. If you configure the ONS 15454 for a 23-inch rack, two additional inches of cable management area are available on each side of the assembly. See the "AMP CHAMP EIA" section and the "AMP CHAMP Installation" section and the for more information.

1.10.5 Alarm Cable Management

Route alarm cables out the nearest side of the shelf assembly through the space provided. Tiewrap eyelets below the alarm pin field can be used to manage alarm cables. Cutouts are protected to prevent chaffing of the cables.

1.10.6 BIC Rear Cover Installation

The ONS 15454 has an optional backplane interface connector (BIC) rear cover. This clear plastic cover provides additional protection for the cables and connectors on the backplane ( ).

Figure 1-38 Clear BIC Rear Cover

Procedure: Install the BIC Rear Cover


Step 1 Locate the three screws that run vertically along the edges of the backplane.

Only one pair of screws lines up with the screw slots on the mounting brackets, making them easy to locate.

Step 2 Loosen the top and bottom screws on one edge of the backplane to provide room to slide the mounting brackets into place using the u-shaped screw slots on each end.

Step 3 Slide one of the mounting brackets into place and tighten the screws.

Step 4 Repeat Steps 2 and 3 for the second mounting bracket.

Step 5 Attach the cover by hanging it from the mounting screws on the back of the mounting brackets and pulling it down until it fits snugly into place.

Description
Check
Configure computer
 

Verify that the computer has a 486 or higher processor and 128 Megabytes or more of RAM. The operating system should be Windows 95/98, NT, or UNIX. The browser should either be Netscape Navigator 4.08 or higher or Microsoft Internet Explorer 4.0 or higher. Netscape Navigator can be installed from the Cisco ONS 15454 system software CD shipped with the system.

 

Verify that a straight-through CAT 4 or CAT 5 cable with RJ-45 connectors on each end is used to connect the computer to the LAN port on the TCC card.

 

Verify that the computer TCP/IP connection is installed on the computer. If the computer has never been connected to a network, see the Control Panel>Network>Configuration screen on Windows 95/98 to verify TCP/IP installation.

 
Install Cards
 

Install TCC/TCC+ and XC/XCVT cards. Slots 7 and 11 hold redundant TCC cards. Slots 8 and 10 hold redundant XC/XCVT cards.

Install one TCC and let it initialize before installing any additional cards. The red Fail LED on the TCC will flash for approximately 30 seconds and all remaining LEDs will blink once in sequence. The ACT/STBY LED will be green/amber when the card is initialized. The IP address for the node, the temperature of the ONS 15454, and the time of day will be displayed on the LCD. Default time of day is 12:00 AM, January 1, 1970

 

Verify that each card turns up successfully. For more information, see the "Card Turn-Up" section.

 

Ensure that transmit and receive fiber patchcords are correctly connected to the optic cards.

 

Verify that TCC/TCC+ cards and XC/XCVT cards are installed in the ONS 15454 in the correct slots. Do not operate the ONS 15454 with only one TCC/TCC+ or one XC/XCVT card installed. Always use redundant cards.

 
Connect computer
 

When connecting through a LAN, you must first obtain a valid IP address from your network administrator. After obtaining a valid IP address, connect directly to the ONS 15454 through either the LAN port on the TCC or the LAN pins on the rear of the shelf. In the CTC, go to the Provisioning>Network tabs and set the IP address, subnet mask, and default router address.

You can also use the buttons on LCD panel to set your IP address, subnet mask, and default router address.

 

Connect the computer LAN cable to the RJ-45 port marked "LAN" on the faceplate of a TCC card.

 

Get the IP address for the node from the LCD screen on the ONS 15454. Record the IP address for future reference.

 

Open the Internet browser to connect with the network element.

 

Enter the ONS 15454's IP address in the address field of the browser program. Press Return.

 
Log into the CTC
 

A log in screen appears. No password is required for the first log in. Network administrators should set up a new user name and a password for security. User names and passwords are case sensitive.

 

The CTC main screen appears. The screen graphically depicts the ONS 15454 shelf assembly.

 

Verify that the TCC and XC/XCVT card(s) are correctly installed. The cards appear in the graphic depiction of the shelf assembly as white when successfully installed. The card name and slot numbers where the cards are installed should be identical to the physical installation.

 
Set up security
 

To set up user security accounts, go to the Provisioning>Security screen. Superusers can add and modify other accounts.

 

Set up accounts for users as required for the local site.

 
Provision node
 

Go to the Provisioning>General screen. The Node Name, Contact, and Description are displayed. Set the node name.

 

In the Provisioning>General screen, set the time zone, date, and time options as desired.

 

Go to the Provisioning>Ring screen. Configure the Node ID to Ring Disabled, or to the desired ring number in a BLSR ring configuration.

 
Connect to the ONS 15454 over a Local Area Network (LAN)
 

Change the ONS 15454 IP address to a valid local LAN network IP address in the Provisioning>Network screen.

 

Select the subnet mask.

 

Enter a valid default router, if applicable.

 

Click Apply to reboot the TCC card and activate the new address.

 

Change TCP/IP settings on the PC connected to the ONS 15454 so that it is on the same subnet as the Gateway network element.

 

Verify that the Netmask field on the PC's TCP/IP settings match the ONS 15454's subnet mask.

 

Restart the PC, if necessary.

 

After restart, open the browser software and enter the new IP address assigned to the ONS 15454.

 

Select Provisioning>SonetDCC to view the DCCs over SONET links. DCCs are disabled by default. Select and enable desired DCCs.

 
Provision Timing References
 

Set timing references for the shelf assembly. Select Provisioning>Timing.

 

For an external BITS clock, set the Timing Mode to External Time.

 

For Synchronous Status Messaging (SSM), the SSM Message Set field displays clock specifications.

 

Set Quality of RES to the Quality of the timing reference being received, if applicable.

 

Set BITS 1 and BITS 2 to In Service. The Coding and Framing fields display clock specifications.

 

Check the Sync Messaging Enabled box if you are using SSM.

 

Set the AIS Threshold if AIS should be inserted on the BITS. (Not supported when SSM is enabled.)

 

Set NE Reference 1 and NE Reference 2 to BITS 1 and BITS 2, respectively.

 

Set BITS 1 Out and BITS 2 Out as desired to provide timing output using the timing output pins on the ONS 15454 backplane.

 

Install any service cards to be used in the ONS 15454. Slot restrictions may apply.

 

Verify that when a card is installed, the Fail LED blinks for over 30 seconds and then the remaining LEDs each flash once in sequence.

 

Verify that the green ACT LED turns on for active cards and the yellow STBY LED turns on for standby cards. The yellow SF LED may persist if far-end ports are not all connected.

 

Verify that all cards are installed in the correct slots and are white on the main CTC craft interface screen. This confirms that each card is installed successfully.

 

Go to the Alarms screen and verify that no equipment alarms are issued against the installed cards.

 

Connect all cables (near end and far end) for each installed service card port.

 
Provision Ports
 

Go to the service card's Provisioning screen for all connected ports and set the ports to In Service.

 

For ports that use concatenation, set concatenation as needed within the Circuit provisioning screen.

 

Check Enabled Sync Messages box to use SSM on each port, if applicable.

 

Ensure that all links are active to external network elements where cross-connects will be mapped.

 

Map cross-connects to the Circuits tab and create cross-connects as needed.

 
Verify Protection and Save the Database
 

Remove active cards to verify that standby cards become active.

 

Save the network element database. Record the location of the saved database file for future reference.
