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.
You can mount the ONS 15454 in a 19- or 23-inch rack (482.6 or 584.2 mm). The shelf assembly weighs
approximately 55 pounds (24.94 kg) 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 and LC connectors on the card faceplate. Fiber-optic cables are routed into
the front of the destination cards. Electrical cards (DS-1, DS-3, DS3XM, 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 preinstalled on the backplane. See the Electrical Interface
Assemblies for more information about the EIAs.
ONS_15454_Reference_Manual_R8.5.x_--_Shelf_and_Backplane_Hardware
Overview 4

The ONS 15454 is powered using -48 VDC 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
•
Rack Installation
The ONS 15454 is mounted in a 19- or 23-in. (482.6- or 584.2-mm) equipment rack. The shelf assembly
projects five inches (127 mm) from the front of the rack. It mounts in both Electronic Industries Alliance
(EIA) standard and Telcordia-standard racks. The shelf assembly is a total of 17 inches (431.8 mm) wide
with no mounting ears attached. Ring runs are not provided by Cisco and might hinder side-by-side
installation of shelves where space is limited.
The ONS 15454 measures 18.25 inches (463.5 mm) high, 19 or 23 inches (482.6 or 584.2 mm) wide
(depending on which way the mounting ears are attached), 12.018 inches (305.2 mm) deep for standard door
and 13.810 inches (350.7 mm) for deep door. You can install up to four ONS 15454 shelves in a seven-foot
(2133.6 mm) equipment rack. The ONS 15454 must have one inch (25.4 mm) 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: A 10-Gbps-compatible shelf assembly (15454-SA-ANSI or 15454-SA-HD) and fan-tray assembly
(15454-FTA3, 15454-FTA3-T, or 15454-CC-FTA) are required if ONS 15454 XC10G and ONS 15454
XC-VXC-10G cards are installed in the shelf.

Rack Installation 5

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 nonconductive 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 (584.2 mm) rack, but you can reverse the
mounting bracket to fit the smaller 19-inch (482.6 mm) rack.
Mounting a Single Node
Mounting the ONS 15454 in a rack requires a minimum of 18.5 inches (469.9 mm) of vertical rack space and
one additional inch (25.4 mm) 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.
ONS_15454_Reference_Manual_R8.5.x_--_Shelf_and_Backplane_Hardware
Figure 1-1: Cisco ONS 15454 ANSI Dimensions 6

Figure 1-2: Mounting an ONS 15454 in a Rack
File:39392.jpg
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.
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.
Mounting Multiple Nodes
Most standard (Telcordia GR-63-CORE, 19-inch [482.6 mm] or 23-inch [584.2 mm]) seven-foot (2,133 mm)
racks can hold four ONS 15454 shelves and a fuse and alarm panel. However, unequal flange racks are
limited to three ONS 15454 shelves and a fuse and alarm panel or four ONS 15454 shelves 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 (2.133 m) 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.
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 preinstalled in a seven-foot (2.133 m) rack. The bay assembly is available in a
three- or four-shelf configuration. The three-shelf configuration includes three ONS 15454 shelf assemblies,
a prewired fuse and alarm panel, and two cable-management trays. The four-shelf configuration includes four
ONS 15454 shelf assemblies and a prewired fuse and alarm panel. You can order optional fiber channels
with either configuration. Installation procedures are included in the Unpacking and Installing the Cisco ONS
15454 Four-Shelf and Zero-Shelf Bay Assembly document that ships with the Bay Assembly,
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 on the ONS 15454 shelf or the network. You can use the LCD to
further isolate alarms. The front door (Figure 1-3) provides access to the shelf assembly, cable-management
tray, fan-tray assembly, and LCD screen.
Figure 1-3: The ONS 15454 Front Door
ONS_15454_Reference_Manual_R8.5.x_--_Shelf_and_Backplane_Hardware
Figure 1-2: Mounting an ONS 15454 in a Rack 7

The ONS 15454 ships with a standard door but can also accommodate a deep door and extended fiber clips
(15454-DOOR-KIT) to provide additional room for cabling (Figure 1-4).
Figure 1-4: Cisco ONS 15454 Deep Door
ONS_15454_Reference_Manual_R8.5.x_--_Shelf_and_Backplane_Hardware
Figure 1-3: The ONS 15454 Front Door 8

The ONS 15454 door locks with a pinned hex key that ships with the ONS 15454. A button on the right side
of the shelf assembly releases the door. You can remove the front door of the ONS 15454 to provide
unrestricted access to the front of the shelf assembly. Before you remove the front door, you have to remove
the ground strap of the front door (Figure 1-5).

Figure 1-6 shows how to remove the front door.
Figure 1-6: Removing the ONS 15454 Front Door
An erasable label is pasted on the inside of the front door (Figure 1-7). You can use the label to record slot
assignments, port assignments, card types, node ID, rack ID, and serial number for the ONS 15454.

Note: The front door label also includes the Class I and Class 1M laser warning (Figure 1-8).
Figure 1-8: Laser Warning on the Front-Door Label
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) as shown in Figure 1-9. Each cover is held in place with nine 6-32 x 3/8 inch
Phillips screws.
Note: See the Electrical Interface Assemblies for information on EIAs.
Figure 1-9: Backplane Covers
ONS_15454_Reference_Manual_R8.5.x_--_Shelf_and_Backplane_Hardware
Figure 1-7: Front-Door Erasable Label 11

Lower Backplane Cover
The lower section of the ONS 15454 backplane is covered by either a clear plastic protector
(15454-SA-ANSI) or a sheet metal cover (15454-SA-HD), 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 1-10).
Figure 1-10: Removing the Lower Backplane Cover
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 1-11 shows the rear cover screw locations.
Figure 1-11: Backplane Attachment for Cover
ONS_15454_Reference_Manual_R8.5.x_--_Shelf_and_Backplane_Hardware
Figure 1-9: Backplane Covers 12

You can also install the optional spacers if more space is needed between the cables and rear cover (Figure
1-12).
Figure 1-12: Installing the Plastic Rear Cover with Spacers
Alarm Interface Panel
The AIP is located above the alarm contacts 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 nonvolatile memory chip that stores the unique node address (MAC address).
ONS_15454_Reference_Manual_R8.5.x_--_Shelf_and_Backplane_Hardware
Figure 1-11: Backplane Attachment for Cover 13

Note: The MAC address identifies the nodes that support circuits. It allows Cisco Transport Controller
(CTC) to determine circuit sources, destinations, and spans. The TCC2/TCC2P cards in the ONS 15454 also
use the MAC address to store the node database.
The 5-A AIP (73-7665-XX) is required when installing fan-tray assembly 15454-FTA3 or 15454-CC-FTA,
which comes preinstalled on the shelf assembly (15454-SA-ANSI or 15454-SA-HD).
Note: A blown fuse on the AIP board can cause the LCD display to go blank.
Alarm Interface Panel Replacement
If the alarm interface panel (AIP) fails, a MAC Fail alarm appears on the CTC Alarms menu and/or the LCD
display on the fan-tray assembly goes blank. To perform an in-service replacement of the AIP, you must
contact Cisco Technical Assistance Center (TAC). For contact information, go to the TAC website at
http://www.cisco.com/tac.
You can replace the AIP on an in-service system without affecting traffic (except Ethernet traffic on nodes
running a software release earlier than Release 4.0). The circuit repair feature allows you to repair circuits
affected by MAC address changes on one node at a time. Circuit repair works 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 2-A AIP with a 5-A fan-tray assembly; doing so causes 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, do not change any
hardware or repair circuits until after the software upgrade is complete. Replace an AIP during a maintenance
window. Resetting the active TCC2/TCC2P card can cause a service disruption of less then 50 ms to optical
or electrical traffic. Resetting the active TCC2/TCC2P card causes a service disruption of three to five
minutes on all E-Series Ethernet traffic due to spanning tree reconvergence. Refer to the Cisco ONS 15454
Troubleshooting Guide for an AIP replacement procedure.
Electrical Interface Assemblies
Optional EIA backplane covers are typically preinstalled when ordered with the ONS 15454. EIAs must be
ordered when using DS-1, DS-3, DS3XM, or EC-1 cards. This section describes each EIA.
Six different EIA backplane covers are available for the ONS 15454: BNC, High-Density BNC, MiniBNC,
SMB, AMP Champ, UBIC-H (Universal Backplane Interface Connector-Horizontal), and UBIC-V
(Vertical). 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. UBIC-V EIAs
have SCSI connectors. They are available for use with any DS-1, DS-3, or EC-1 card, but are intended for
use with high-density electrical cards.
Note: The MiniBNC EIAs only support cables using the Trompetor connectors for termination.
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
ONS_15454_Reference_Manual_R8.5.x_--_Shelf_and_Backplane_Hardware
Alarm Interface Panel 14

forth). As you face the rear of the ONS 15454 shelf assembly, the right side is the A side and the left side is
the B side. The top of the EIA connector columns are labeled with the corresponding slot number, and EIA
connector pairs are marked transmit (Tx) and receive (Rx) to correspond to transmit and receive cables.
Note: For information about EIA types, protection schemes, and card slots, see Card Protection.
EIA Installation
Optional EIA backplane covers are typically preinstalled when ordered with the ONS 15454. A minimal
amount of assembly might be required when EIAs are ordered separately from the ONS 15454. 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 [37 meters]) is
less than the maximum distance available with standard RG-59 (734A) cable (306 feet [93 meters]). The
maximum distance when using the RG-59 (734A) cable is 450 feet (137 meters). 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 at 22 MHz.• For RG-59 (734A) the attenuation rate is 11.6 dB/kft at 22 MHz.•

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
ONS_15454_Reference_Manual_R8.5.x_--_Shelf_and_Backplane_Hardware
Table 1-2: EIA Configurations Compatible with the 15454-SA-ANSI and the 15454-SA-HD 17

designed for long runs. You can use BNC EIAs for DS-3 (including the DS3XM-6 and DS3XM-12) or EC-1
cards.
Figure 1-13 shows the ONS 15454 with preinstalled BNC EIAs.
To install coaxial cable with BNC connectors, refer to the "Install Shelf and Backplane Cable" chapter in the
Cisco ONS 15454 Procedure Guide.
Figure 1-13: BNC Backplane for Use in 1:1 Protection Schemes
BNC Connectors
The EIA side marked "A" has 24 pairs of BNC connectors. The first 12 pairs of BNC connectors correspond
to Ports 1 to 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 to 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 the standard BNC EIA
panel 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 to 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 to 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 the standard BNC EIA panel 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.

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.

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 and DS3XM-12) or EC-1 cards. Figure
1-15 shows the ONS 15454 with preinstalled high-density BNC EIAs.
To install coaxial cable with high-density BNC connectors, refer to the "Install Shelf and Backplane Cable"
in the Cisco ONS 15454 Procedure Guide.

BNC Insertion and Removal Tool 19

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 to 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 to 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 except Slots 6
and 12.
MiniBNC EIA
The ONS 15454 MiniBNC EIA supports a maximum of 192 transmit and receive DS-3 connections, 96 per
side (A and B) through 192 miniBNC connectors on each side. If you install BNC EIAs on both sides of the
unit, the ONS 15454 hosts up to 192 circuits. The MiniBNC EIAs are designed to support DS-3 and EC-1
signals.
The MiniBNC EIA supports the following cards:
DS3-12, DS3N-12• DS3i-N-12• DS3-12E, DS3N-12E• EC1-12• DS3XM-6• DS3XM-12• DS3/EC1-48•
