Product Overview

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 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.

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.

Tools and Parts Required

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=)
