This document contains instructions for installing or replacing cable-management kit components in the Cisco 12012 Gigabit Switch Router (GSR). The Cisco 12012 is a member of the Cisco 12000 series of Internet routing products. The Cisco 12012 is aimed at scaling the Internet and enterprise backbones to speeds of OC-3/STM-1 (155 Mbps), OC-12/STM-4 (622 Mbps), and OC-48/STM-16 (2.4 Gbps). The Cisco 12012 is built around a high-speed switching fabric that is scalable from 5 to 60 Gbps, providing high-performance to support Internet Protocol (IP) -based local-area networks (LANs) and wide-area networks (WANs).
The sections in this document include the following:
The Cisco 12012 has two card cages; the upper card cage and the lower card cage. (Refer to Figure 1.) The upper card cage has 12 user-configurable slots available for line cards and a Gigabit Route Processor (GRP). One additional slot (rightmost slot) in the upper card cage is non-configurable; it is reserved for an alarm card. The line cards and the GRP are not slot dependent; you can install the line cards and the GRP in any of the first 12 available slots.
The lower card cage, located behind the air filter, has five horizontal slots for switch fabric cards.
Below the lower card cage is a power supply bay. Up to four AC-input power supplies or two DC-input power supplies can be installed in the bay.
A cable-management system manages the line card interface cables in the upper card cage, keeping them organized and free from sharp bends, which can degrade cable performance. The Cisco 12012 cable-management system consists of two components: a horizontal cable-management tray, which is attached to the frame directly above the upper card cage, and a vertical cable-management bracket, which is attached to each line card. (Refer to Figure 2.)
The horizontal cable-management tray keeps the interface cables organized by upper card cage slot and free of sharp bends as the cables enter the Cisco 12012 from either the left or right side and are routed to the individual line cards.
The vertical cable-management bracket attaches to each line card with two captive screws. Rubber clips on the vertical cable-management bracket hold the line card's interface cables in place, allowing installation and removal of adjacent line cards. A vertical cable-management bracket can be detached from the line card with the interface cables still in their clips, aligned to their respective line card ports. This speeds up a line card removal and replacement.
Before you begin the procedures in this document, review the safety guidelines in this section to avoid injuring yourself or damaging the equipment.
In addition, review the safety warnings listed in the document Regulatory Compliance and Safety Information for the Cisco 12012 Gigabit Switch Router (Document Number 78-4347-xx) that accompanied your Cisco 12012 before installing, configuring, or maintaining the router.
The following guidelines will help ensure your safety and protect the equipment. This list is not inclusive of all potentially hazardous situations, so be alert.
The line cards, Gigabit Route Processor (GRP), switch fabric cards, alarm card, blower modules, and redundant power supplies are designed to be removed and replaced while the system is operating without presenting an electrical hazard or damage to the system.
Follow these basic guidelines when working with any electrical equipment:
In addition, use the guidelines that follow when working with any equipment that is disconnected from a power source, but still connected to telephone or network wiring:
Electrostatic discharge damage, which can occur when electronic boards or components are handled improperly, can result in complete or intermittent failures.
Following are guidelines for preventing ESD damage:
 | Caution You should periodically check the resistance value of the antistatic strap. The measurement should be between 1 and 10 megohms. |
You need the following tools and parts to install or replace a horizontal cable-management tray or vertical cable-management bracket:
This section provides the procedures for removing and replacing a horizontal cable-management tray or a vertical cable-management bracket.
The horizontal cable-management tray is mounted above the upper card cage and spans the width of the frame. It is secured to the frame with four screws. Perform the following procedure to remove the horizontal cable-management tray:
Step 1 Attach an antistatic wrist strap to yourself and to one of the two ESD connection sockets located on the front edges of the upper card cage or to bare metal on the frame.
Step 2 Proceeding from left to right, identify each line card and write down the following information:
Step 3 Proceeding from left to right in the upper card cage, select a line card. Starting with the bottom port on the line card and working up (for cards with multiple ports only), disconnect the network interface cable from the line card ports. Do not remove the cables from the vertical cable-management bracket. (Refer to Figure 2.)
Step 4 Loosen the captive screws at the top and bottom of the vertical cable-management bracket. (Refer to Figure 2.)
Step 5 Remove the vertical cable-management bracket from the line card and remove the attached cables from the horizontal cable-management tray. Position the vertical cable-management bracket out of the way of the horizontal cable-management tray.
Repeat Step 3 through Step 5 for the rest of the vertical cable-management brackets on the line cards.
Step 6 Remove the four screws at the lower edge the horizontal cable-management tray. (Refer to Figure 3.)
Step 7 Pivot the bottom of the tray out, away from the frame, to disengage three horizontal cable-management tray tabs (at the top of the tray) from the slots in the frame.
Step 8 Remove the horizontal cable-management tray from the frame and set it aside.
Perform the following steps to install a replacement horizontal cable-management tray:
Step 1 Attach an antistatic wrist strap to yourself and to one of the two ESD connection sockets located on the front edges of the upper card cage or to bare metal on the frame.
Step 2 Remove the replacement horizontal cable-management tray from its shipping packaging.
Step 3 Angle the horizontal cable-management tray so that the top of the tray goes into the front of the frame first. Fit the three tabs at the top of the horizontal cable-management tray into the slots in the frame.
Step 4 Pivot the horizontal cable-management tray down so that the rest of the tray is in contact with the frame.
Step 5 Secure the horizontal cable-management tray in the frame with the four screws.
Step 6 Consulting your list of line cards and their interface cable connections, select the vertical cable-management bracket for the first line card (proceeding from left to right in the upper card cage).
Step 7 Carefully place the interface cables in the horizontal cable tray and route them down through the bottom of the horizontal cable-management tray directly over the line card attached to the vertical cable-management bracket.
