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.

Figure 1 Cisco 12012—Front View

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 .)

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.

Figure 2 Cisco 12012 Cable-Management System

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.

Safety Guidelines

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 supports your Cisco 12012 before installing, configuring, or maintaining the router.

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 card cage assembly.

Keep tools and assembly 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.

Safety with Electricity

The line cards, 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.

Preventing Electrostatic Discharge Damage

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:

Always use an ESD-preventive wrist strap or ankle strap and ensure that it makes good skin contact.

When removing or installing a horizontal cable-management tray or vertical cable-management bracket, connect the equipment end of a ground strap to one of the two ESD ground sockets located on the front sides of the upper card cage or to a bare metal surface on the frame.

If you plan to return a replaced part to the factory, immediately place it in a static shielding bag to avoid ESD damage to the part.

The wrist strap only protects the part from ESD voltages on the body; ESD voltages on clothing can still cause damage.


Caution   
You should periodically check the resistance value of the antistatic strap. The measurement should be between 1 and 10 megohms.

Tools and Parts Required

You need the following tools and parts to install or replace a horizontal cable-management tray or vertical cable-management bracket:

3/16-inch flat-blade screwdriver

ESD-preventive wrist strap

A cable-management kit (Product Number ACS-GSR12-CCBLM=) or a vertical cable-management kit (Product Number ACS-GSR-LCCBLM=)

Removing and Replacing the Cable-Management System

This section provides the procedures for removing and replacing a horizontal cable-management tray or a vertical cable-management bracket.

Removing a Horizontal Cable-Management Tray

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:

The slot number and type of line card.

The interface cable connections to the line card ports. You will need to reconnect the interface cables to the same line card ports.

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 .)

Step 4 Loosen the captive screws at the top and bottom of the vertical cable-management bracket. (Refer to .)

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.
