This chapter provides procedures for installing the Cisco ONS 15454 SDH. Chapter topics include:

Warning Only trained and qualified personnel should be allowed to install, replace, or service this equipment.

Warning This equipment must be installed and maintained by service personnel as defined by AS/NZS 3260. Incorrectly connecting this equipment to a general-purpose outlet could be hazardous. The telecommunications lines must be disconnected 1) before unplugging the main power connector and/or 2) when the housing is open.

Warning The ONS 15454 SDH is intended for installation in restricted access areas. A restricted access area is one where service personnel gain access by using a special tool, lock, key, or other means of security. A restricted access area is controlled by the authority responsible for the location.

Note   The ONS15454 SDH is suitable for mounting on concrete or other non-combustible surfaces only.

1.1 Installation Overview

ONS 15454 SDH assemblies are typically connected to a fuse and alarm panel that provides centralized alarm connection points and distributed power for the ONS 15454 SDH. 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 SDH in an ETSI rack. This ETSI rack is not supplied by Cisco. The shelf assembly weighs approximately 23 kilograms (50,7 lbs) without cards installed. The shelf has two front doors for added security, a fan-tray assembly module for cooling, and extensive fiber-management space. The electrical facility connection assembly in the upper section of the shelf provides access to user-defined (external) alarms and controls and power terminals.

The ONS 15454 SDH front door allows access to the shelf assembly, fan-tray assembly, and cable-management area.

Caution   The ONS 15454 SDH relies upon the protective devices in the building installation to protect against short circuits, overcurrent, and grounding faults. Ensure that the protective devices have the proper rating to protect the system, and that they comply with national and local codes.

Warning A readily accessible two-poled disconnect device must be incorporated in the fixed wiring.

ONS 15454 SDH optical (STM-N) card faceplates have SC connectors. Fiber-optic cables are routed to the front of destination cards. Electrical cards (such as the E1-N-14, the E3-12, and the DS3i-N-12) require electrical facility connection assemblies (EFCAs) as cable-connection points for the shelf assembly. The ONS 15454 SDH is powered using -48V DC power. Positive, negative, and ground-power terminals are accessible on FMEC cards in the EFCAs. Table 1-1 lists the tasks required to install an ONS 15454 SDH.

Note   In this chapter, "node" and "shelf assembly" are used interchangeably. In the installation context, these terms have the same meaning. Otherwise, shelf assembly refers to the steel enclosure that holds cards and connects power, and node refers to the entire hardware and software system.

Install the ONS 15454 SDH in compliance with your local and national electrical codes:

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

1.2 Installation Equipment

You will need the following tools and equipment to install and test the ONS 15454 SDH.

1.2.1 Included Materials

These materials are required for installation and are supplied with the ONS 15454 SDH. The shipped quantity of each item is in parentheses.

Caution   Only use the power cable shipped with the ONS 15454 SDH.

1.2.2 User-Supplied Materials

The following materials and tools are required for installation but are not supplied with the ONS 15454 SDH.

1.2.2.1 Tools Needed

1.2.2.2 Test Equipment

1.3 Rack Installation

Caution   The chassis must be mounted on a rack that is permanently affixed to the building to maintain stability.

The ONS 15454 SDH is mounted in an ETSI equipment rack. The shelf assembly projects 40 mm from the front of the rack. The shelf assembly is 431.8 mm wide with no mounting brackets (ears) attached, and 535 mm wide with brackets attached. The shelf assembly measures 616.5 mm high and 280 mm deep. Ring runs are not provided by Cisco and can hinder side-by-side shelf installation where space is limited.

You can install up to three ONS 15454 SDHs in an ETSI rack. The ONS 15454 SDH must have 40 mm of airspace below an installed shelf assembly to allow air flow to the fan intake. If an ONS 15454 SDH is installed below a previously installed shelf assembly, the air ramp between the two provides sufficient air flow and should not be modified in any way. Figure 1-1 shows the dimensions of the ONS 15454 SDH.

A node should be mounted at the bottom of the rack if it is the only unit in the rack. When mounting a node in a partially filled rack, load the rack from the bottom to the top with the heaviest component at the bottom of the rack. If the rack is provided with stabilizing devices, install the stabilizers before mounting or servicing the unit in the rack.

Warning To prevent the system from overheating, do not operate it in an area that exceeds the maximum recommended ambient temperature of 45°C (113°F).

Warning To prevent bodily injury when mounting or servicing this unit in a rack, you must take special precautions to ensure that the system remains stable. The following guidelines are provided to ensure your safety

Warning Care must be given when connecting nodes to the supply circuit so that wiring is not overloaded.

1.3.1 Mount a Single Node

Mounting the ONS 15454 SDH in a rack requires a minimum of 616.5 mm of vertical rack space (plus 40 mm for air flow). To ensure the mounting is secure, use two to four M6 mounting screws for each side of the shelf assembly. Figure 1-2 shows the rack-mounting position for the ONS 15454 SDH. In a single node configuration, one air-ramp on the top and one air-ramp on the bottom of the node is recommended.

The shelf assembly is most easily installed by two people. However, you can install it alone by using temporary set screws. Reduce extra weight if possible by emptying the shelf assembly and removing the front door. (See the "Remove the Front Door" Procedure).

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

Step 2   Using the hex tool that was included with the assembly, install temporary set screws into the holes that will not be used to mount the shelf. Let the set screws protrude sufficiently to hold the mounting brackets.

Step 3   Lift the shelf assembly to the desired rack position and place it on the set screws.

Step 4   Align the screw holes on the mounting ears with the mounting holes in the rack.

Step 5   Install one mounting screw in each side of the assembly.

Step 6   When the shelf assembly is secured to the rack, install the remaining mounting screws.

---

Note    Use at least one set of the horizontal screw slots on the ONS 15454 SDH to prevent future slippage.

---

Step 7   Using the hex tool, remove the temporary set screws.

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

Step 2   Align the screw holes on the mounting ears with the mounting holes in the rack.

Step 3   Have one person hold the shelf assembly in place while the other person installs one mounting screw in each side of the assembly.

Step 4   When the shelf assembly is secured to the rack, install the remaining mounting screws if necessary.

---

Note    Use at least one set of the horizontal screw slots on the ONS 15454 SDH to prevent future slippage.

---

1.3.2 Mount the Air Ramp

The air ramp is needed if you install more than one shelf in the ETSI rack. Install the air ramp below the top shelf assembly. To ensure the mounting is secure, use one or two M6 mounting screws for each side of the shelf assembly. Figure 1-3 shows the rack-mounting position for the air ramp.

Note   Install the air ramp after you have connected and routed all cables for the ONS 15454 SDH.

Procedure: Mount the Air Ramp in a Rack

Step 2   Align the screw holes on the mounting ears with the mounting holes in the rack.

Step 3   Install one mounting screw in each side of the assembly.

Step 4   When the air ramp is secured to the rack, install the remaining mounting screws if necessary.

1.3.3 Mount Multiple Nodes

The standard ETSI racks can hold three ONS 15454 SDH, and two air ramps.

Procedure: Mount the Shelf Assembly in a Rack

Step 2   Mount the first air ramp above the first ONS 15454 SDH.

Step 3   Repeat the procedure with the second ONS 15454 SDH and the second air ramp.

Step 4   Install the third-party fuse and alarm panel in the top space.

Note   The ONS 15454 SDH must have 40 mm of airspace below the installed shelf assembly to allow air flow to the fan intake. If a second ONS 15454 SDH is installed above a shelf assembly, the air ramp between the shelves provides the space for air flow. However, if the ONS 15454 SDH is installed above third-party equipment, provide a minimum of 40 mm between the third-party unit and the bottom of the ONS 15454 SDH. The third-party equipment must not generate heat upward into the ONS 15454 SDH. The top of the third-party unit should be a non-combustible surface when an air ramp is not installed between the ONS 15454 SDH and the third-party unit.

1.3.3.1 Three-Node Configuration

A single ONS 15454 SDH node can accommodate up to 120 DS-3/E-3 or 140 E1 drops. If you need to drop more than the maximum allowed for a single node, you can link multiple nodes using a fiber-optic bus. However, you cannot merge multiple nodes into a single ONS 15454 SDH. You can use STM-4, STM-16, or STM-64 fiber spans to link the nodes as you would link any other network nodes. Nodes can be co-located in a facility to aggregate local traffic.

Figure 1-4 shows a three-shelf node setup. Each shelf assembly is identified as a separate node in Cisco Transport Controller (CTC), the ONS 15454 SDH software interface. Traffic must be mapped using CTC cross-connect options. In the figure, each node uses redundant fiber-optic cards. Node 1 uses redundant STM-N transport and STM-N bus cards for a total of four cards. Nodes 2 and 3 each use two redundant STM-N bus cards for a total of four cards, with eight free slots remaining. The three-node example presented here is one of many ways to set up a multiple-node configuration.

1.3.3.2 ONS 15454 SDH Bay Assembly

The Cisco ONS 15454 SDH Bay Assembly simplifies ordering and installing the ONS 15454 SDH because it allows you to order shelf assemblies pre-installed in an ETSI rack. The Bay Assembly is available in a three-shelf configuration. The three-shelf configuration includes three ONS 15454 SDH shelf assemblies, a slot for third-party fuse and alarm panel, two air ramps and two cable-management trays. A three-shelf ONS 15454 SDH bay assembly is shown in Figure 1-5.

1.4 Front Door Access

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 SDH. 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 "Alarm Monitoring and Management" for more information.

This section tells you how to access ONS 15454 SDH equipment in the front compartment. The ONS 15454 SDH features a locked door to the front compartment and a screw-in panel over the EFCA. A pinned Allen key that unlocks the front door ships with the ONS 15454 SDH. A button on the right side of the shelf assembly releases the door. The front door provides access to the shelf assembly, cable-management tray, fan-tray assembly, and LCD screen (Figure 1-8).

You can remove the front door of the ONS 15454 SDH to provide unrestricted access to the front of the shelf assembly. An erasable label is pasted on the inside of the front door (Figure 1-6). You can use the label to record slot assignments, port assignments, card types, node ID, rack ID, and serial number for the ONS 15454 SDH.

Note   When you are done installing/servicing the shelf assembly, the door must be reinstalled. The door serves as the electrical closure for the unit.

Note   The front door label also includes the Class-I and Class-1M laser warning shown in the laser warning on the front-door label (Figure 1-7).

Step 5   Attach the cover faceplate to the shelf using the screws on the top of the cover faceplate.

1.6 Fan-Tray Assembly Installation

The fan-tray assembly is located at the bottom of the ONS 15454 SDH front compartment. The fan-tray assembly is a removable drawer that holds fans and fan-control circuitry for the ONS 15454 SDH. You do not need to remove the front door when removing or installing the fan-tray assembly, but Cisco recommends removal.

Note   When you have finished installing/servicing the shelf assembly, reinstall the FMEC cover faceplate. The door provides security for the electrical connections.

After you install the fan-tray assembly, you should only need to access it if a fan failure occurs or you need to replace or clean the fan-tray air filter.

The front of the fan-tray assembly has an LCD screen that provides slot and port-level information for all ONS 15454 SDH card slots, including the number of critical, major, and minor alarms.

The fan-tray assembly features an air filter at the bottom of the tray that you can install and remove by hand. Remove and visually inspect this filter every 30 days and keep spare filters in stock. Consult the maintenance chapter of the Cisco ONS 15454 SDH Troubleshooting and Maintenance Guide for information about cleaning and maintaining the fan-tray air filter.

Caution   Do not operate an ONS 15454 SDH without a fan-tray air filter. A fan-tray air filter is mandatory.

Note   An error message appears on the TCC-I and in CTC when the fan-tray assembly is removed from the shelf

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 assembly illuminates when one or more fans fail. To replace the fan-tray assembly, see the "Install the Fan-Tray Assembly" Procedure. The red Fan Fail LED clears after you install a working fan-tray assembly.

Note   An error message appears on the TCC-I, fan-tray LED, and in CTC when one fan is deactivated or mechanically blocked.

Fan speed is controlled by TCC-I 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-I card fails, the fans automatically shift to high speed. The temperature measured by the TCC-I sensors is displayed on the LCD screen.

To install or replace the fan-tray assembly, it is not necessary to move the cable management facilities. You can remove the fan-tray assembly using the retractable handles.

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

Procedure: Install the Fan-Tray Assembly

1.8 EFCA

The ONS 15454 SDH has an electrical facility connection assembly (EFCA) located at the top of the shelf. The EFCA provides connection for installing external alarms, timing input and output, and craft interface terminals. This section describes the EFCA and the pin assignments for the field.

1.8.1 Alarm Installation

The MIC-A/P card provides connection for alarm contacts into and out of the node. The pin connectors, signal names, and functions are listed in Table 1-3.

1.8.2 Timing Installation

The MIC-C/T/P provides 1.0/2.3 miniature coax connectors that are used for timing input and output. The bottom connectors are for "1" timing, and the top connectors are for "2" timing. In each case, the left connector is the input and the right connector is the output. The input connectors for timing provide a 75-Ohm termination. System cables are available that can convert timing clocks from 75 Ohms to 100/120 Ohms. Table 1-4 shows MIC-C/T/P pin assignments.

A high-impedance option (> 3 k Ohm or greater) is possible through a jumper on the MIC-C/T/P card. You can change the top timing input to high impedance by removing the jumper on P3 on the MIC-C/T/P card. You can change the bottom timing input to high impedance by removing the jumper on P2 on the MIC-C/T/P card.

Note   Refer to ITU-T G.813 for rules about provisioning timing references

For more detailed information about timing, see 3.5 Setting Up ONS 15454 SDH Timing.

1.8.3 Modem Interface Installation

The modem connector of the MIC-C/T/P card on the ONS 15454 SDH EFCA is reserved for future use.

1.8.4 Craft Interface Installation

You can use the CRAFT connector of the MIC-C/T/P card on the ONS 15454 SDH EFCA to connect a workstation such as a VT100-type craft interface. Table 1-5 shows the pin assignments for the CRAFT connector.

1.8.5 LAN Installation

Use the LAN connection of the MIC-C/T/P card on the ONS 15454 SDH to connect the ONS 15454 SDH to a workstation, an Ethernet LAN, or a LAN modem for remote access to the node. For more information about the ONS 15454 SDH craft interface software (CTC) and how to connect to a LAN modem, see "Set up PC and Log into CTC". Table 1-6 shows the LAN pin assignments.

Before you can connect an ONS 15454 SDH to other ONS 15454 SDHs or to a LAN, you must change the default IP address that is shipped with each ONS 15454 SDH (192.168.0.2). See the "Change IP Address, Default Router, and Network Mask Using the LCD" Procedure.

.

*The Cisco ONS 15454 SDH is DCE.

1.9 Card Installation

This section describes how to install ONS 15454 SDH cards. Most card installation procedures are the same. The XC10G and TCC-I installation procedures are different from the main procedure, so they are combined in a separate procedure. The card installation order is important. Here is the proper sequence:

1. TCC-I cards

2. XC10G cards

3. Optical cards

4. Electrical cards

5. Ethernet cards

Note   All cards boot from the active TCC-I card, which houses the ONS 15454 SDH software. Therefore, you must install the TCC-I card to boot any other cards. See "Set up PC and Log into CTC" for information about the TCC-I card and software versions.

Note   Before installing cards, verify that the power is turned on.

ONS 15454 SDH cards have electrical plugs at the back that plug into electrical connectors on the shelf assembly backplane. When the card ejectors are fully closed, the cards plug into the assembly backplane. Figure 1-14 shows card installation.

Caution   Always use the supplied ESD wristband when working with an ONS 15454 SDH. Plug the wristband cable into the ESD jack located on the middle-right outside edge of the shelf assembly.

Warning During this procedure, wear grounding wrist straps to avoid ESD damage to the card. Do not directly touch the backplane with your hand or any metal tool, or you could shock yourself.

Warning Class-I (21 CFR 1040.10 and 1040.11) and Class-1M (IEC 60825-1 2001-01) laser products.

Warning Invisible laser radiation can be emitted from the end of the unterminated fiber cable or connector. Do not stare into the beam or view directly with optical instruments. Viewing the laser output with certain optical instruments (for example, eye loupes, magnifiers, and microscopes) within a distance of 100 mm can pose an eye hazard. Use of controls or adjustments or performance of procedures other than those specified can result in hazardous radiation exposure.

Caution   The laser of the OC-192 LR/STM64 LH 1550 is active when the card is booted and the safety key is in the on position (labeled 1). The port does not need to be in service for the laser to be active. The laser is off when the safety key is in the off position (labeled 0).

Caution   Hazardous voltage or energy may be present on the backplane when the system is operating. Use caution when servicing.

Procedure: Install ONS 15454 SDH Cards

Step 2   Slide the cards along the guide rails into the card slot.

Step 3   Close the ejectors.

1.9.1 Slot Requirements

The ONS 15454 SDH shelf assembly has 17 card slots that are numbered sequentially from left to right. Slots 1 - 4 and 14 - 17 are multispeed slots. They can host any ONS 15454 SDH traffic card except OC48 ELR/STM16 EH 100 GHz and OC192/STM64. Slots 5, 6, 12 and 13 are high-speed slots. They can host any ONS 15454 SDH card.

Slots 7 and 11 are dedicated to TCC-I cards. Slots 8 and 10 are dedicated to cross-connect (XC10G) cards.

Note   Slot 9 is intended for future use.

Slots 3 and 15 can host E1N-14 and DS3i-N-12 cards that are used in 1:N protection.

Note   Do not operate the ONS 15454 SDH with a single TCC-I card or a single XC10G card installed. Always operate the shelf assembly with one working and one protect card of the same type.

Shelf assembly slots have symbols indicating the type of cards that you can install in the slots. Each ONS 15454 SDH card has a corresponding symbol. The symbol on the card must match the symbol on the slot. Table 1-7 shows the slot and card symbol definitions.

Table 1-8 lists the number of ports, line rates, connector options, and connector locations for ONS 15454 SDH optical and electrical cards.

* 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.

Procedure: Install the TCC-I and XC10G Cards

Although the installation procedure is the same for both TCC-I and XC10G cards, you must install the TCC-I card and let it initialize before installing the XC10G cards. The TCC-I card houses the ONS 15454 SDH software. For a detailed explanation, see "Set up PC and Log into CTC."

Caution   Hazardous voltage or energy may be present on the backplane when the system is operating. Use caution when servicing.

Step 2   Slide the card along the guide rails into the correct slot (Slot 8 or 10 for the XC10G and Slot 7 or 11 for the TCC-I).

Step 3   Close the ejectors.

Step 4   Verify that power is applied to the shelf assembly.

Step 5   Verify the LED activity as described in Table 1-9.

---

Note    If the FAIL LED is illuminated continuously on the TCC-I card, see the tip below about the TCC-I automatic upload.

---

Step 6   Verify that the ACT/STBY LED is the correct color for the card (green for active, amber for standby). The fan-tray assembly LCD displays the node IP address, the ONS 15454 SDH temperature, and the time of day. The default time and date is 12:00 AM, January 1, 1970.

Tip When a newly installed TCC-I card and the active TCC-I card have different versions of the ONS 15454 SDH software, the new card automatically loads the software version that the active card is running. This is an automatic process that does not need to be initiated. However, the active TCC-I card will not boot up normally during this process. When the new card is first inserted, the red FAIL LED stays on for a short period. The FAIL LED then blinks normally and 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-I card. After the new card loads the software for approximately 30 minutes, it becomes the standby card and the amber LED is illuminated.

Procedure: Install Optical, Electrical, and Ethernet Cards

Although the installation procedure is the same for optical, electrical, and Ethernet cards, you must install the optical cards before installing the electrical cards.

Caution   Before installing an OC192 LR/STM64 LH 1550 card, make sure the safety key on the faceplate is in the off position (labeled 0). When the safety key is in the on position (labeled 1), the laser is activated.

Warning Invisible laser radiation can be emitted from the end of the unterminated fiber cable or connector. Do not stare into the beam or view directly with optical instruments. Viewing the laser output with certain optical instruments (for example, eye loupes, magnifiers, and microscopes) within a distance of 100 mm can pose an eye hazard. Use of controls or adjustments or performance of procedures other than those specified can result in hazardous radiation exposure.

Caution   Hazardous voltage or energy may be present on the backplane when the system is operating. Use caution when servicing.

Step 2   Slide the card along the guide rails into the correct slot.

Step 3   Close the ejectors.

Step 4   Verify that power is applied to the shelf assembly.

Step 5   Verify the LED activity, as described in Table 1-10.

Step 6   Verify that the ACT or ACT/STBY LED is on. The signal fail (SF) LED can persist until all card ports connect to their far-end counterparts and a signal is present.

Step 7   Use CTC to verify that the card appears in the correct slot on the CTC node view. See "Set up PC and Log into CTC" for CTC information and setup instructions.

Caution   An unused card slot should be filled with a blank faceplate (Cisco P/N 15454E-BLANK). The blank faceplate ensures proper air flow when operating the ONS 15454 SDH. An unused FMEC slot should be filled with a blank Faceplate (Cisco P/N 15454E-BLANK-FMEC). The blank faceplate ensures proper functionality without EMC disturbances.

1.9.2 Card Software Installation

After you install an ONS 15454 SDH card in a valid card slot, the card software automatically updates to the version that operates correctly with the system software installed on the TCC-I. When the TCC-I is writing to the active or standby TCC-I, its Active or Standby LED will blink. To prevent memory corruption, do not pull the TCC-I out during this time. You can use CTC inventory commands to configure the card software. See "Card Provisioning" for more information.

1.9.3 Gigabit Interface Converter

GBICs are hot-swappable input/output devices that plug into a Gigabit Ethernet card to link the port with the fiber-optic network. The type of GBIC determines the maximum distance that the Ethernet traffic will travel from the card to the next network device.

Cisco provides two GBIC models for the E1000-2-G card and three for the G1000-4 card. The E1000-2-G supports the 15454E-GBIC-SX= for short-reach applications and the 15454E-GBIC-LX= for long-reach applications. The short reach model connects to multimode fiber up to 550 m long. The long reach model requires single-mode fiber up to 10 km long. The G1000-4 card supports both the 15454E-GBIC-SX= and 15454E-GBIC-LX= and additionally the 15454E-GBIC-ZX= for extra long-reach applications on the 1550 nm wavelength for up to eighty kilometers. Because the GBICs are very similar in appearance, check the GBIC label carefully before installing it. For a description of GBICs and their capabilities, see "Ethernet Operation." A gigabit interface converter is shown in Figure 1-15.

Table 1-11 shows the available GBICs.

Procedure: Install Gigabit Interface Converters

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 Figure 1-16).

GBICs are hot-swappable and can be installed or removed when the card or shelf assembly is powered and running.

---

Note    GBICs are keyed to prevent incorrect installation.

---

Step 4   Slide the GBIC through the cover flap until you hear a click.

The click indicates the GBIC is locked into the slot.

---

Note    GBICs are Class-I laser products. These products have been tested and comply with Class-I limits.

---

Warning Invisible laser radiation may be emitted from disconnected fibers or connectors. Do not stare into beams or view directly with optical instruments.

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.

Install and route the cable. See the "Optical Cable Management" section for routing instructions.

Procedure: Remove a Gigabit Interface Converter

Step 2   Release the GBIC from the slot by simultaneously squeezing the two plastic tabs 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.

1.10 FMEC Card Installation

Caution   Always use the supplied ESD wristband when working with an ONS 15454 SDH. Plug the wristband cable into the ESD jack located on the middle-right outside edge of the shelf assembly.

ONS 15454 SDH cards have electrical plugs at the back that plug into electrical connectors on the shelf assembly backplane. When the screws are fully locked, the card plugs into the assembly backplane. Figure 1-17 shows card installation.

Procedure: Install ONS 15454 SDH FMEC cards

Caution   Hazardous voltage or energy may be present on the backplane when the system is operating. Use caution when servicing.

Step 2   Slide the card along the guide rails into the desired card slot.

Step 3   Push the card gently into the connector.

Step 4   Lock the screw.

1.10.1 Slot Requirements

The ONS 15454 SDH EFCA has 12 card slots numbered sequentially from left to right. Slots 18 - 22 and 25 - 29 provide electrical access for corresponding slots. They can host FMEC-E1, FMEC-E3/DS3, and FMEC-DS1/E1 cards. Assignment is as follows:

Slots 23 and 24 provide system power and system interface for alarms, timing, and LAN connections. They host MIC-A/P and MIC-C/T/P cards.

Shelf assembly slots have symbols indicating the type of cards that you can install in them. Each ONS 15454 SDH card has a corresponding symbol. The symbol on the card must match the symbol on the slot. Table 1-12 shows the slot-card symbol definitions.

Table 1-13 lists the number of ports, line rates, connector options, and connector locations for ONS 15454 SDH electrical cards.

1.10.2 Card Turn Up

The procedure for turning up ONS 15454 SDH FMEC cards is identical for each FMEC card.

Procedure: Verify Successful Turn Up of All Cards

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

Step 3   Verify that the card appears in the correct slot in the CTC node view.

Step 4   Verify that the card is white in the CTC node view.

Caution   An unused card slot should be filled with a blank faceplate (Cisco P/N 15454E-BLANK). The blank faceplate ensures proper air flow when operating the ONS 15454 SDH. An unused FMEC slot should be filled with a blank Faceplate (Cisco P/N 15454E-BLANK-FMEC). The blank faceplate ensures proper functionality without EMC disturbances.

1.11 Fiber-Optic Cable Installation

This section explains how to install optical fibers on OC-N/STM-M cards.

Caution   Always use the supplied ESD wristband when working with an ONS 15454 SDH. Plug the wristband cable into the ESD jack located on the middle-right outside edge of the shelf assembly.

ONS OC-N/STM-M cards feature SC connectors. To install fiber-optic cables in the ONS 15454 SDH, a fiber cable with the corresponding connector type must be connected to the transmit and receive ports on the ONS 15454 SDH cards. On ONS 15454 SDH 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 protect fibers be labeled at each end of the fiber span to avoid confusion. For information about fiber cable management, see the "Optical Cable Management" section.

Warning Class-I (21 CFR 1040.10 and 1040.11) and Class-1M (IEC 60825-1 2001-01) laser products.

Warning Invisible laser radiation can be emitted from the end of the unterminated fiber cable or connector. Do not stare into the beam or view directly with optical instruments. Viewing the laser output with certain optical instruments (for example, eye loupes, magnifiers, and microscopes) within a distance of 100 mm can pose an eye hazard. Use of controls or adjustments or performance of procedures other than those specified can result in hazardous radiation exposure.

Caution   The laser is active when the card is booted and the safety key is in the on position (labeled 1). The port does not have to be in service for the laser to be on. The laser is off when the safety key is off (labeled 0).

Note   Do not use fiber loopbacks with the OC192 LR/STM64 LH 1550 card unless you are using a 20 dB attenuator. Never connect a direct fiber loopback. Using fiber loopbacks causes irreparable damage to the OC192 LR/STM64 LH 1550 card.

Procedure: Install Fiber-Optic Cables on STM-N Cards

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

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 shelf assembly.

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

Procedure: Install the Fiber Boot

Cisco provides clear plastic fiber boots for the STM-1, STM-4, and STM-16 cards. The boots prevent hanging fibers from bending too sharply and degrading performance. The boots also prevent the front door from interfering with hanging fibers. Figure 1-19 shows the 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.

Note   The fiber boot does not support the OC-48 IR/STM-16 SH AS 1310, OC-48 LR/STM-16 LH AS 1550, or OC-192/STM-64 cards. The boots are not necessary for these cards because of the angled SC connectors on the cards.

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.

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

1.12 Cable Routing and Management

The ONS 15454 SDH cable management facilities include the following:

Figure 1-20 shows the cable management facilities that you can access through the fold-down front door, including the cable-routing channel and the jumper routing fins.

1.12.1 Optical Cable Management

Optical cables connect to the SC connectors on the faceplates of optical cards and GBICs. Route optical cables down through the fiber management clips on the optical card faceplate (shown in Figure 1-21) or, if the optical cables are connected to GBICs, route them down through the jumper routing fins. (Ethernet cards do not have fiber management clips.) Route optical cables 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.

Procedure: Route Fiber-Optic Cables in the Shelf Assembly

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

Step 3   GBICs do not have fiber clips. If you are routing optical cable from an E1000-2-G or G1000-4 card, skip to Step 5.

Step 4   Route the cables into the cable-management tray.

Step 5   Route the cables out either side of the cable-management tray and through the cutouts on each side of the shelf assembly. Use the reversible fiber guides to route cables out of the desired side.

Step 6   Close the fold-down front door when all cables in the front compartment are properly routed.

Figure 1-22 shows the fold-down front door of the shelf assembly opened to display the cable-routing channel.

1.12.2 Coaxial Cable Management

Coaxial cables connect to FMEC-E1, FMEC-E3/DS3, and MIC-C/T/P cards on the ONS 15454 SDH EFCA.

---

Note    When using the coaxial cable with 1.0/2.3 miniature coax connectors, remember that the maximum distance available depends on the loss of the cable. Generally thinner cable has a lower maximum distance available than standard cable. If for example, you only use the RG179 cable, the maximum available distance is 15 m (50 feet) versus 137 m (450 feet) available with the larger RG59 cable.

---

Step 2   Use short pigtails to terminate the shelf assembly.

Step 3   Use standard coaxial cable connected to the thinner cable for the remainder of the cable run. When using a 3 m (10 foot) section of the RG179, you can attach a maximum length of 133 m (437 feet) of RG59. When using a 9-m (30-foot) section of RG179, you can attach a maximum length of 95 m (311 feet) of RG59.

The shorter maximum distance for RG179 is due to a higher attenuation for the thinner cable. The attenuation for RG59 cable (based upon testing with Belden 923, the equivalent of 328A cable) is ~1.0 dB/30 m (~1.0 dB/100 feet) for the DS-3 data rate. The attenuation of RG179 is 6.3 db/30 m (6.3 db/100 feet). Use a cable loss figure of 5.0 dB for calculations. When using different types of coaxial cable, refer to the data sheets of these cables for loss calculation.

1.12.3 FMEC-DS1/E1 Cable Management

DB-37 cables connect to FMEC-DS1/E1 on the ONS 15454 SDH EFCA. Route the cables according to local site practice and through the side cutouts on either side of the ONS 15454 SDH. The rubber-coated edges of the side cutouts prevent the cables from chafing.

1.12.4 Alarm Cable Management

Alarm cables connect to the MIC-A/P card on the ONS 15454 SDH EFCA. Route the cables according to local site practice and through the side cutouts on either side of the ONS 15454 SDH. The rubber-coated edges of the side cutouts prevent the cables from chafing.

1.12.5 Timing Cable Management

Coaxial timing cables connect to the MIC-C/T/P card on the ONS 15454 SDH EFCA. Cable attenuation is allowed up to 6 dB @ 2 MHz. Route the cables according to local site practice and through the side cutouts on either side of the ONS 15454 SDH. The coated edges of the side cutouts prevent the cables from chafing.

1.12.6 Craft Cable Management

Craft cables connect to the MIC-C/T/P card on the ONS 15454 SDH EFCA. Route the cables according to local site practice and through the side cutouts on either side of the ONS 15454 SDH. The coated edges of the side cutouts prevent the cables from chafing.

1.12.7 LAN Cable Management

LAN cables connect to the MIC-C/T/P card on the ONS 15454 SDH EFCA. Route the cables according to local site practice and through the side cutouts on either side of the ONS 15454 SDH. The coated edges of the side cutouts prevent the cables from chafing.
