2.Cisco 12012 Gigabit Switch Router Switch Fabric Cards Replacement Instructions
Product Numbers: GSR12-CSC=, GSR12-SFC=
Document Order Number: DOC-784343=
This document covers the installation and replacement of clock and scheduler cards and switch fabric cards 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).

3.Product Overview

The Cisco 12012 has two card cages; the upper card cage and the lower card cage. (Refer to .) The upper card cage has 12 user-configurable slots available for line cards and a route processor (RP). 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 RP are not slot dependent; you can install the line cards and the RP in any of the first 12 available slots.

5.Safety Guidelines

Before you begin this installation, 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 supports your Cisco 12012 before installing, configuring, or maintaining the router.
6.Safety with Equipment

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
.

•Always disconnect all power cords and interface cables before moving the system.

•Keep tools and components away from walk areas.

•Do not work alone if potentially hazardous conditions exist.

•Do not perform any action that creates a potential hazard to people or makes the equipment unsafe.

•Carefully examine your work area for possible hazards such as moist floors, ungrounded power extension cables, and missing safety grounds.

7.Safety with Electricity

The line cards, route processor (RP), 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:

•Before beginning any procedures requiring access to the interior of the Cisco 12012, locate the emergency power-off switch for the room in which you are working.

•Look carefully for possible hazards in your work area, such as moist floors, ungrounded power extension cables, and missing safety grounds.

•If an electrical accident occurs, proceed as follows:

•Use caution; do not become a victim yourself. Disconnect power to the system.

•If possible, send another person to get medical aid. Otherwise, assess the condition of the victim and then call for help.

•Determine if the person needs rescue breathing or external cardiac compressions; then take appropriate action.

•Disconnect all power and external cables before installing or removing a router.

•Never assume that power has been disconnected from a circuit; always check.

•Do not perform any action that creates a potential hazard to people or makes the equipment unsafe.

•Never install equipment that appears damaged.

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:

•Never install telephone wiring during a lightning storm.

•Never install telephone jacks in wet locations unless the jack is specifically designed for wet locations.

•Never touch uninsulated telephone wires or terminals unless the telephone line has been disconnected at the network interface.

•Use caution when installing or modifying telephone lines.
8.Removing a Card From the Lower Card Cage

Perform the following steps to remove a card from the lower card cage:

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
If necessary, power down the Cisco 12012 by turning the DC-input power supply power switch to OFF (or STANDBY on an AC-input power supply) on each power supply.

Step 3
To gain access to the lower card cage, loosen the two captive screws on the front of the air filter tray and pivot the tray down, away from the lower card cage. (Refer to .)
