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



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) while the front door is open.



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.



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, although Cisco recommends that the front door remain 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. 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 user documentation for the related equipment. The front door of the ONS 15454 allows access to the shelf assembly, fan-tray assembly, and cable-management area. The backplanes provide access to alarm contacts, external interface contacts, power terminals, and BNC/SMB connectors.


Warning The ONS 15454 relies on the protective devices in the building installation to protect against short circuit, overcurrent, and grounding faults. Ensure that the protective devices are properly rated to protect the system, and that they comply with national and local codes.



Warning Incorporate a readily-accessible, two-poled disconnect device in the fixed wiring.


You can mount the ONS 15454 in a 19- or 23-inch rack. The shelf assembly weighs approximately 55 pounds with no cards installed. The shelf assembly includes a front door for added security, a fan tray module for cooling, and extensive cable-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. Electrical cards (DS-1, DS-3, DS3XM-6, and EC-1) require electrical interface assemblies (EIAs) to provide the cable connection points for the shelf assembly. In most cases, EIAs are ordered with the ONS 15454 and come pre-installed on the backplane. See the "Electrical Interface Assemblies" section for more information about the EIAs.

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


Note In this chapter, the terms "ONS 15454" and "shelf assembly" are used interchangeably. In the installation context, these terms have the same meaning. Otherwise, shelf assembly refers to the physical steel enclosure that holds cards and connects power, and ONS 15454 refers to the entire system, both hardware and software.


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

United States: National Fire Protection Association (NFPA) 70; United States National Electrical Code

Canada: Canadian Electrical Code, Part I, CSA C22.1

Other countries: If local and national electrical codes, are not available, refer to IEC 364, Part 1 through Part 7.


Warning Dispose of this product according to all national laws and regulations.


1.2 Rack Installation


Warning To prevent the equipment from overheating, do not operate it in an area that exceeds the maximum recommended ambient temperature of 131°F (55°C) unless configured for inversion temperature (I-temp). All I-temp rated components are -40°C to +65°C. To prevent airflow restriction, allow at least 3 inches (7.6 cm) of clearance around the ventilation openings.


The ONS 15454 is mounted in a 19- or 23-inch equipment rack. The shelf assembly projects five 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. 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 (47 by 48.3 by 30.5 cm). You can install up to four ONS 15454s in a seven-foot equipment rack. The ONS 15454 must have 1 inch of airspace below the installed shelf assembly to allow air flow to the fan intake. If a second ONS 15454 is installed underneath the shelf assembly, the air ramp on top of the lower shelf assembly provides the air spacing needed and should not be modified in any way. Figure 1-1 shows the dimensions of the ONS 15454.


Note The 10 Gbps compatible shelf assembly (15454-SA-ANSI) and fan-tray assembly (15454-FTA3 or 15454-FTA3-T) are required with the ONS 15454 XC-10G, OC-192, G1000-4, and OC-48 any slot (AS) cards.



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



Warning The ONS 15454 must have 1 inch of airspace below the installed shelf assembly 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.


Figure 1-1 Cisco ONS 15454 dimensions

1.2.1 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.

1.2.2 Mounting a Single Node

Mounting the ONS 15454 in a rack requires a minimum of 18.5 inches of vertical rack space and one additional 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 Mounting an ONS 15454 in a rack

Two people should install the shelf assembly; however, one person can install it using the temporary set screws included. The shelf assembly should be empty for easier lifting. The front door can also be removed to lighten the shelf assembly.


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


1.2.3 Mounting Multiple Nodes

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 and a fuse and alarm panel from an adjacent rack.

If you are using the external (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 external (bottom) brackets, you can install four shelf assemblies in a rack. The advantage to using the bottom brackets is that you can replace the filter without removing the fan tray.

1.2.3.1 ONS 15454 Bay Assembly

The Cisco ONS 15454 Bay Assembly simplifies ordering and installing the ONS 15454 because it 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 cable-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 1-3.

Figure 1-3 A Four-shelf ONS 15454 Bay Assembly

1.3 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.

The ONS 15454 features a locked door to the front compartment. A pinned hex key that unlocks the front door ships with the ONS 15454. A button on the right side of the shelf assembly releases the door. The front door ( Figure 1-4) provides access to the shelf assembly, cable-management tray, fan-tray assembly, and LCD screen.

Figure 1-4 The ONS 15454 front door

You can remove the front door of the ONS 15454 to provide unrestricted access to the front of the shelf assembly ( Figure 1-5). An erasable label ( Figure 1-6) is pasted on the inside of the front door. You can use the label to record slot assignments, port assignments, card types, node ID, rack ID, and serial number for the ONS 15454.

Figure 1-5 Removing the ONS 15454 front door

Figure 1-6 The front-door erasable label


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).


Figure 1-7 The laser warning on the front-door label

1.4 Backplane Covers

If a backplane does not have an EIA panel installed, it should have two sheet metal backplane covers (one on each side of the backplane) ( Figure 1-8). (See the "Electrical Interface Assemblies" section for information on EIAs.) Each cover is held in place with nine 6-32 x 3/8 inch Phillips screws.

Figure 1-8 Backplane covers

1.4.1 Lower Backplane Cover

The lower section of the ONS 15454 backplane is covered by a clear plastic protector, which is held in place by five 6-32 x 1/2 inch screws. Remove the lower backplane cover to access the alarm interface panel (AIP), alarm pin fields, frame ground, and power terminals ( Figure 1-9).

Figure 1-9 Removing the lower backplane cover

1.4.2 Rear Cover

The ONS 15454 has an optional clear plastic rear cover. This clear plastic cover provides additional protection for the cables and connectors on the backplane ( Figure 1-10). The rear cover screw locations are shown in Figure 1-11. You can also install the optional spacers if more space is needed between the cables and rear cover ( Figure 1-12).

Figure 1-10 Clear rear cover

Figure 1-11 Backplane attachment for cover

Figure 1-12 Installing the plastic rear cover with spacers

1.4.3 Alarm Interface Panel

The AIP is located above the alarm pin fields on the lower section of the backplane. The AIP provides surge protection for the ONS 15454. 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 address (MAC address).


Note The 5-amp AIP (73-7665-XX) is required when installing the new fan-tray assembly (15454-FTA3), which comes preinstalled on the shelf assembly (15454-SA-ANSI).



Note The MAC address identifies the nodes that support circuits. It allows CTC to determine circuit sources, destinations, and spans. The Timing Communication and Control+ (TCC+) cards in the ONS 15454 also reads the MAC address to store the node database.



Note A blown fuse on the AIP board can cause the LCD display to go blank.


1.4.4 Alarm Interface Panel Replacement

If the alarm interface panel (AIP) fails, a MAC Fail alarm displays on the CTC Alarms menu and/or the LCD display on the fan tray will go blank. To perform an in-service replacement of the AIP, you must contact Cisco Technical Assistance Center (TAC) at 877-323-7368.

You can replace the AIP on an in-service system without affecting traffic (except Ethernet traffic). The circuit repair feature allows you to repair circuits affected by MAC address changes on a single node at a time. Circuit repair will work when all nodes are running the same software version. Each individual AIP upgrade requires an individual circuit repair; if AIPs are replaced on two nodes, the circuit repair must be performed twice.


Caution Do not use a 2A AIP with a 5A fan-tray assembly; doing so will cause a blown fuse on the AIP.


Note Ensure that all nodes in the affected network are running the same software version before replacing the AIP and repairing circuits. If you need to upgrade nodes to the same software version, no hardware should be changed or circuit repair performed until after the software upgrade is complete.



Note Replace an AIP in a maintenance window. Resetting the active TCC+ can cause a service disruption of less then 50 ms to OC-n or DS-n traffic. Resetting the active TCC+ will cause a service disruption of 3-5 minutes on all E Series Ethernet traffic due to Spanning Tree Reconvergence.


1.5 Electrical Interface Assemblies

Optional EIA backplane covers are typically pre-installed when ordered with the ONS 15454. EIAs must be ordered when using DS-1, DS-3, DS3XM-6, or EC-1 cards. This section describes each EIA.

A minimum amount of assembly may be required when EIAs are ordered separately from the ONS 15454. Four different EIA backplane covers are available for the ONS 15454: BNC, High-Density BNC, SMB, and AMP Champ. This section describes each EIA in detail. If the shelf was not shipped with the correct EIA interface, you must order and install the correct EIA.

EIAs are attached to the shelf assembly backplane to provide electrical interface cable connections. EIAs are available with SMB and BNC connectors for DS-3 or EC-1 cards. EIAs are available with AMP Champ connectors for DS-1 cards. You must use SMB EIAs for DS-1 twisted-pair cable installation. 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).

EIAs have two sides. As you face the rear of the ONS 15454 shelf assembly, the right-hand side is the A side and the left-hand side is the B side. You can install EIAs on one or both sides of the ONS 15454 backplane in any combination. For example, you can use an AMP Champ EIA on side A and a BNC EIA on side B. The top of the EIA connector columns are labelled with the corresponding slot number, and EIA connector pairs are marked Tx and Rx to correspond to transmit and receive cables. EIAs come pre-installed on the ONS 15454 when ordered with the node.

If you are installing EIAs after the shelf assembly is installed, plug the EIA into the backplane. The EIA has six electrical connectors that plug into six corresponding backplane connectors. The EIA backplane must replace the standard sheet metal cover to provide access to 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 board using standoffs on the EIA board.

When using the RG-179 coaxial cable on an EIA, the maximum distance available (122 feet) is less than the maximum distance available with standard RG-59 (735A) cable (306 feet). The maximum distance when using the RG-59 (734A) cable is 450 feet. The shorter maximum distance available with the RG179 is due to a higher attenuation rate for the thinner cable. Attenuation rates are calculated using a DS-3 signal:

For RG-179, the attenuation rate is 59 dB/kft @ 22 MHz.

For RG-59 (735A) the attenuation rate is 23 dB/kft @ 22 MHz.

1.5.1 BNC EIA

The ONS 15454 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 shelf assembly, the ONS 15454 hosts up to 48 circuits. The BNC connectors on the EIA supports Trompeter UCBJ224 (75 Ohm) 4 leg connectors (King or ITT are also compatible). Right-angle mating connectors for the connecting cable are AMP 413588-2 (75 Ohm) connectors. If preferred, you can also use a straight connector of the same type. 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. You can use BNC EIAs for DS-3 (including the DS3XM-6) or EC-1 cards.

Figure 1-13 shows the ONS 15454 with pre-installed BNC EIAs.

To install coaxial cable with BNC connectors, refer to the Cisco ONS 15454 Procedure Guide.

Figure 1-13 A BNC backplane for use in 1:1 protection schemes

1.5.1.1 BNC Connectors

The EIA side marked "A" has 24 pairs of BNC connectors. The first 12 pairs of BNC connectors correspond to Ports 1-12 for a 12-port card and map to Slot 2 on the shelf assembly. The BNC connector pairs are marked "Tx" and "Rx" to indicate transmit and receive cables for each port. You can install an additional card in Slot 1 as a protect card for the card in Slot 2. The second 12 BNC connector pairs correspond to Ports 1-12 for a 12-port card and map to Slot 4 on the shelf assembly. You can install an additional card in Slot 3 as a protect card for the card in Slot 4. Slots 5 and 6 do not support DS-3 cards when BNC connectors are used.

The EIA side marked "B" provides an additional 24 pairs of BNC connectors. The first 12 BNC connector pairs correspond to Ports 1-12 for a 12-port card and map to Slot 14 on the shelf assembly. The BNC connector pairs are marked "Tx" and "Rx" to indicate transmit and receive cables for each port. You can install an additional card in Slot 15 as a protect card for the card in Slot 14. The second 12 BNC connector pairs correspond to Ports 1-12 for a 12-port card and map to Slot 16 on the shelf assembly. You can install an additional card in Slot 17 as a protect card for the card in Slot 16. Slots 12 and 13 do not support DS-3 cards when BNC connectors are used.

When BNC connectors are used with a DS3N-12 card in Slot 3 or 15, the 1:N card protection extends only to the two slots adjacent to the 1:N card due to BNC wiring constraints.

1.5.1.2 BNC Insertion and Removal Tool

Due to the large number of BNC connectors on the High-Density BNC EIA, you might require a special tool for inserting and removing BNC EIAs ( Figure 1-14). This tool also helps with ONS 15454 patch panel connections.

1.5.2 High-Density BNC EIA

The ONS 15454 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. The High-Density BNC EIA supports Trompeter UCBJ224 (75 Ohm) 4 leg connectors (King or ITT are also compatible). Use straight connectors on RG-59/U cable to connect to the High-Density BNC EIA. Cisco recommends these cables for connection to a patch panel; they are designed for long runs. You can use High-Density BNC EIAs for DS-3 (including the DS3XM-6) or EC-1 cards. Figure 1-15 shows the ONS 15454 with pre-installed High-Density BNC EIAs.

To install coaxial cable with High-Density BNC connectors, refer to the Cisco ONS 15454 Procedure Guide.

Figure 1-15 A High-Density BNC backplane for use in 1:N protection schemes

The EIA side marked "A" hosts 48 pairs of BNC connectors. Each column of connector pairs is numbered and corresponds to the slot of the same number. The first column (12 pairs) of BNC connectors corresponds to Slot 1 on the shelf assembly, the second column to Slot 2, the third column to Slot 4, and the fourth column to Slot 5. The rows of connectors correspond to Ports 1-12 of a 12-port card.

The EIA side marked "B" provides an additional 48 pairs of BNC connectors. The first column (12 pairs) of BNC connectors corresponds to Slot 13 on the shelf assembly, the second column to Slot 14, the third column to Slot 16, and the fourth column to Slot 17. The rows of connectors correspond to Ports 1-12 of a 12-port card. The BNC connector pairs are marked "Tx" and "Rx" to indicate transmit and receive cables for each port. The High-Density BNC EIA supports both 1:1 and 1:N protection across all slots.

1.5.3 SMB EIA

The ONS 15454 SMB EIA supports AMP 415484-1 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. Range does not affect loopback testing.

You can use SMB EIAs with DS-1, DS-3 (including the DS3XM-6), and EC-1 cards. If you use DS-1 cards, use the DS-1 electrical interface adapter to terminate the twisted pair DS-1 cable from the backplane (see the "Electrical Interface Adapters" section). SMB EIAs support 14 ports per slot when used with a DS-1 card, 12 ports per slot when used with a DS-3 or EC-1 card, and 6 ports per slot when used with a DS3XM-6 card.

Figure 1-16 shows the ONS 15454 with pre-installed SMB EIAs and the sheet metal cover and screw locations for the EIA. The SMB backplane cover is similar to the BNC cover. The SMB connectors on the EIA are AMP 415504-3 (75 Ohm) 4 leg connectors.

To install SMB connectors, refer to the Cisco ONS 15454 Procedure Guide.

Figure 1-16 An SMB EIA backplane

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).

The EIA side marked "A" hosts 84 SMB connectors in six columns of 14 connectors. The "A" side columns are numbered 1-6 and correspond to Slots 1-6 on the shelf assembly. The EIA side marked "B" hosts an additional 84 SMB connectors in six columns of 14 connectors. The "B" side columns are numbered 12-17 and correspond to Slots 12-17 on the shelf assembly. The connector rows are numbered 1-14 and correspond to the 14 ports on a DS-1 card.

For DS-3 or EC-1, the EIA supports 72 transmit and 72 receive connectors, for a total of 144 SMB connectors (72 circuits). If you use a DS-3 or EC-1 card, only Ports 1-12 are active. If you use a DS3XM-6 card, only Ports 1 - 6 are active. The SMB connector pairs are marked "Tx" and "Rx" to identify transmit and receive cables for each port. If you use SMB connectors, you can install DS-1, DS-3, or EC-1 cards in any multispeed slot.

1.5.4 AMP Champ EIA

The ONS 15454 AMP Champ EIA supports 64-pin (32 pair) AMP Champ connectors for each slot on both sides of the shelf assembly where the EIA is installed. Cisco AMP Champ connectors are female AMP # 552246-1 with AMP # 552562-2 bail locks. Each AMP Champ connector supports 14 DS-1 ports. You can use AMP Champ EIAs with DS-1 cards only. Figure 1-17 shows the ONS 15454 with pre-installed AMP Champ EIAs and the corresponding sheet metal cover and screw locations for the EIA.

To install 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 cable diameter .475in.-.540in.) or #2-552496-1 (for cable diameter .540in.-.605in.) 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 and one transmit 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. Table 1-2 shows the pin assignments for the AMP Champ connectors on the ONS 15454 AMP Champ EIA.

Figure 1-17 An AMP EIA Champ backplane

The EIA side marked "A" hosts six AMP Champ connectors. The connectors are numbered 1-6 for the corresponding slots on the shelf assembly. Each AMP Champ connector on the backplane supports 14 DS-1 ports for a DS1-14 card, and each connector features 28 live pairs—one transmit pair and one receive pair—for each DS-1 port.

The EIA side marked "B" hosts six AMP Champ connectors. The connectors are labeled 12-17 for the corresponding slots on the shelf assembly. Each AMP Champ connector on the backplane supports 14 DS-1 ports for a DS1-14 card, and each connector features 28 live pairs—one transmit pair and one receive pair—for each DS-1 port.


Note EIAs are hot-swappable. You do not need to disconnect power to install or remove EIAs.



Caution Always use an electrostatic discharge (ESD) 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.

1.5.5 EIA Replacement

The replacement procedure is the same for all the EIA types. However, installing the AMP Champ EIA requires the additional step of attaching the fastening plate to the bottom of the connector row. Before you attach a new EIA, you must remove the backplane cover or EIA already attached to the ONS 15454.

1.6 Coaxial Cable


Caution Always use the supplied ESD 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 an EIA installed on the ONS 15454 backplane. All DS-3 cables connected to the ONS 15454 DS-3 card must terminate with coaxial cables using the desired connector type to connect to the specified EIA.

The electromagnetic compatibility (EMC) performance of the system depends on good-quality DS-3 coaxial cables, such as Shuner Type G 03233 D, or the equivalent.

1.7 DS-1 Cable

DS-1s support AMP Champ connector cabling and twisted-pair wire-wrap cabling. Twisted-pair wire-wrap cables require SMB EIAs.

1.7.1 Twisted Pair Wire-Wrap Cables

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 ESD 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 EIA on each side of the backplane where DS-1 cables will terminate. You must install special DS-1 electrical interface adapters, commonly referred to as a balun, on every transmit and receive connector for each DS-1 termination.

1.7.2 Electrical Interface Adapters


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


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 1-18 shows the DS-1 electrical interface adapter.

Figure 1-18 DS-1 electrical interface adapter (balun)

Each DS-1 electrical interface adapter 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.


Caution Always use the supplied ESD 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.

1.8 Cable Routing and Management

The ONS 15454 cable management facilities include the following:

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

Plastic horseshoe-shaped fiber guides at each side opening of the cable-routing channel that ensure the proper bend radius is maintained in the fibers


Note You can remove the fiber guide if necessary to create a larger opening (if you need to route CAT-5 Ethernet cables out the side, for example). To remove the fiber guide, take out the three screws that anchor it to the side of the shelf assembly.


A fold-down door that provides access to the cable-management tray

Cable tie-wrap facilities on EIAs that secure cables to the cover panel

Reversible jumper routing fins that enable you to route cables out either side by positioning the fins as desired

Jumper slack storage reels (2) on each side panel that reduce the amount of slack in cables that are connected to other devices


Note To remove the jumper slack storage reels, take out the screw in the center of each reel.


Figure 1-19 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.

Figure 1-19 Managing cables on the front panel

1.8.1 Coaxial Cable Management

Coaxial cables connect to EIAs on the ONS 15454 backplane using cable connectors. EIAs feature cable-management eyelets for tie wrapping or lacing cables to the cover panel.

1.8.2 DS-1 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 (baluns).

1.8.3 AMP Champ Cable Management

EIAs have cable management eyelets to tiewrap or lace cables to the cover panel. Tie wrap 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 is available on each side of the shelf assembly.

1.9 Alarm Expansion Panel

The ONS 15454 alarm expansion panel (AEP) can be used with the AIC-I card to provide an additional 48 dry alarm contacts for the ONS 15454 system, 32 of which are inputs and 16 outputs. The AEP is a printed circuit board assembly that is installed on the backplane. Figure 1-20 shows the AEP board and Figure 1-21 shows a block diagram of the unit.

The AIC-I without an AEP already contains direct alarm contacts. These direct AIC-I alarm contacts are routed through the backplane to wire-wrap pins accessible from the back of the shelf. If you install an AEP, you cannot use the alarm contacts on the wire-wrap pins. For further information about the AIC-I, see the "AIC-I Card" section on page 2-25.

Figure 1-20 AEP printed circuit board assembly

Figure 1-21 AEP block diagram

Each AEP alarm input port has provisionable label and severity, optocoupler isolation, one common 32VDC output for all alarm inputs, and a maximum of 2 mA per input. Each optometal oxide semiconductor MOS alarm output can operate by definable alarm condition, maximum allowed open circuit voltage of 60 VDC, and maximum current of 100 mA. See the "External Alarms and Controls" section on page 2-26 for further information.

1.9.1 Wire-Wrap and Pin Connections

Figure 1-22 shows the wire wrapping connections on the backplane and Table 1-4 shows the wire-wrap pins and corresponding signals on the AIC-I and AEP.

Compliance
ONS15454 cards, when installed in a system, comply with these standards:

Safety: IEC 60950, EN 60950, UL 60950, CSA C22.2 No. 60950, TS 001, AS/NZS 3260

1.10 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 or removed before installing the fan-tray assembly. 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 air filter.

The front of the fan-tray assembly has an LCD screen that provides slot and port-level information for all ONS 15454 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. Refer to the Cisco ONS 15454 Troubleshooting Guide for information about cleaning and maintaining the fan-tray air filter.


Note The 15454-SA-ANSI shelf assembly and 15454-FTA3 fan-tray assembly are required with the ONS 15454 XC10G, OC-192, and OC-48 any slot (AS) cards.



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


Caution The 15454-FTA3 fan-tray assembly can only be installed in ONS 15454 Release 3.1 and later shelf assemblies (15454-SA-ANSI, P/N: 800-19857). It includes a pin that does not allow it to be installed in ONS 15454 shelf assemblies released before ONS 15454 Release 3.1 (15454-SA-NEBS3E, 15454-SA-NEBS3, and 15454-SA-R1, P/N: 800-07149). Equipment damage can result from attempting to install the 15454-FTA3 in a non-compatible shelf assembly.


Note The 15454-FTA3 is not I-temp. To obtain an I-temp fan tray, install the 15454-FTA-T fan-tray assembly in an ONS 15454 Release 3.1 shelf assembly (15454-SA-ANSI). However, do not install the ONS 15454 Release 3.1 or later XC10G, OC-192, and OC-48 any slot (AS) cards in the shelf assembly with the 15454-FTA2 fan-tray assembly.


1.10.1 Fan Speed

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, refer to the Cisco ONS 15454 Troubleshooting Guide. The red Fan Fail LED clears after you install a working fan tray.

Fan speed is controlled by 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.


Note Asterisks (*) next to fan tray names mean the power specification shown below is based on a calculation because an actual measurement was not available at the time of publication.

1.11 Air Filter

The ONS 15454 contains an air filter; NEBS 3E and later versions of the ONS 15454 use a reusable air filter that is installed either beneath the fan-tray assembly or in the optional external filter brackets. Earlier versions of the ONS 15454 use a disposable air filter that is installed beneath the fan-tray assembly only.


Warning Do not reach into a vacant slot or chassis while you install or remove a module or a fan. Exposed circuitry could constitute an energy hazard.


1.11.1 Reusable Air Filter

The reusable filter is made of a gray, open-cell, polyurethane foam that is specially coated to provide fire and fungi resistance. NEBS 3E and later versions of the ONS 15454 use a reusable air filter. Spare filters should be kept in stock.

1.11.2 Disposable Air Filter

The disposable filter is made of spun white polyester that is flame retardant. NEBS 3E and earlier versions of the ONS 15454 use a disposable air filter. This disposable filter is not designed to be cleaned. You can order air filter replacements from Cisco (Cisco P/N: 47-01-00001) or from Universal Air Filter Company, model PE-5:

Universal Air Filter Company (www.uaf.com)

Sauget, IL 62206

1.12 Power and Ground Description

Ground the equipment according to Telcordia standards or local practices.

Cisco recommends the following wiring conventions, but customer conventions prevail:

Red wire for battery connections (-48V DC)

Black wire for battery return connections (0V DC)

The ONS 15454 has redundant -48V DC #8 power terminals on the shelf assembly backplane. The terminals are labeled BAT1, RET1, BAT2, and RET2 and are located on the lower section of the backplane behind a clear plastic cover.

To install redundant power feeds, use four power cables and one ground cable. For a single power feed, only two power cables (#10 AWG, copper conductor, 194°F [90°C]) and one ground cable (#6 AWG) are required. Use a conductor with low impedance to ensure circuit overcurrent protection. However, the conductor must have the capability to safely conduct any faulty current that might be imposed.


Note If you are installing power on a Release 3.0 ONS 15454 shelf assembly (15454-SA-NEBS3E, 15454-SA-NEBS3, and 15454-SA-R1, P/N: 800-07149), the #12 to #14 AWG power cable and #14 AWG ground cable are required.


The existing ground post is a #10-32 bolt. The nut provided for a field connection is also a #10, with an integral lock washer. The lug must be a dual-hole type and rated to accept the #6 AWG cable. Two posts are provided on the Cisco ONS 15454 to accommodate the dual-hole lug. Figure 1-25 shows the location of the ground posts.

Figure 1-25 Ground posts on the ONS 15454 backplane

For information about attaching ferrites to power cabling, refer to the "Ferrites" section.

1.13 Alarm, Timing, LAN, and Craft Pin Connections


Caution Always use the supplied ESD 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 has a backplane pin field located at the bottom of the backplane. The backplane pin field provides 0.045 square inch wire-wrap pins for enabling external alarms, timing input and output, and craft interface terminals. This section describes the backplane pin field and the pin assignments for the field. Figure 1-26 shows the wire-wrap pins on the backplane 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 1-26 shows pinouts for the ONS 15454.

Figure 1-26 ONS 15454 backplane pinouts


Note The X.25, Modem, and TBOS pin fields are not active.


1.13.1 Alarm Contact Connections

The alarm pin field supports up to 17 alarm contacts, including four audible alarms, four visual alarms, one alarm cutoff (ACO), and four user-definable alarm input and output contacts.

Audible alarm contacts are in the LOCAL ALARM AUD pin field and visual contacts are in the LOCAL ALARM VIS pin field. Both of these alarms are in the LOCAL ALARMS category. User-definable contacts are in the ENVIR ALARM IN (external alarm) and ENVIR ALARM OUT (external control) pin fields. These alarms are in the ENVIR ALARMS category; you must have the AIC card installed to use the ENVIR ALARMS. 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 shelf assembly backplane. Visual and audible alarm contacts are classified as Critical, Major, Minor, and Remote. Figure 1-26 shows 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.

1.13.2 Timing Connections

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. Table 1-8 lists the pin assignments for the BITS timing pin fields.

1.13.3 LAN Connections

Use the LAN pins on the ONS 15454 backplane to connect the ONS 15454 to a workstation or Ethernet LAN, or to a LAN modem for remote access to the node. You can also use the LAN port on the TCC+ faceplate to connect a workstation or to connect the ONS 15454 to the network. Table 1-9 shows the LAN pin assignments.

Before you can connect an ONS 15454 to other ONS 15454s or to a LAN, you must change the default IP address that is shipped with each ONS 15454 (192.1.0.2).

* 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.

1.14.2 Card Replacement

To replace an ONS 15454 card with another card of the same type, you do not need to make any changes to the database; remove the old card and replace it with a new card. To replace a card with a card of a different type, physically remove the card and replace it with the new card, then delete the original card from CTC.


Caution Removing any active card from the ONS 15454 can result in traffic interruption. Use caution when replacing cards and verify that only inactive or standby cards are being replaced. If the active card needs to be replaced, switch it to standby prior to removing the card from the node.


Note An improper removal (IMPROPRMVL) alarm is raised whenever a card pull is performed, unless the card is deleted in CTC first. The alarm will clear after the card replacement is complete.



Note In a UPSR, pulling the active XC/XCVT/XC10G without a lockout will cause UPSR circuits to switch.



Warning Do not reach into a vacant slot or chassis while you install or remove a module or a fan. Exposed circuitry could constitute an energy hazard.


1.15 Ferrites

Place third-party ferrites on certain cables to dampen electromagnetic interference (EMI) from the ONS 15454. Ferrites must be added to meet the requirements of GR 1089. Refer to the ferrite manufacturer documentation for proper use and installation of the ferrites. Ferrite placements on the ONS 15454 can include power cables, AMP Champ connectors, baluns, BNC/SMB connectors, and the wire-wrap pin field.
