Product Overview

Figure 1 Cisco 12012—Front View

The lower card cage, located behind the air filter, has five keyed horizontal slots for cards containing

the switch fabric circuitry. The cards provide the physical pathway for data packet exchange between

the line cards in the upper card cage.

There are two types of cards installed in the lower card cage; the clock and scheduler card (CSC)

and the switch fabric card (SFC). Both types of cards are keyed to fit into specific slots in the lower

card cage. You can install the clock and scheduler card only in the top two slots and the switch fabric

card only in the lower three slots. The clock and scheduler card contains the system clock, switch

fabric scheduler circuitry, and the switch fabric. The switch fabric card contains only switch fabric

circuitry.

Below the lower card cage is a power supply bay. The Cisco 12012 can be configured for source AC

or source DC operation. A system configured for source AC operation must have a minimum of two

AC-input power supplies installed. You can install two additional AC-input power supplies for

redundancy and current sharing. Systems configured for source DC operation have one DC-input

power supply installed. You can install a second DC-input power supply for redundancy and current

sharing.

The Cisco 12012 has two blower modules; one located above the upper card cage and one located

below the power supply bay. They draw filtered cooling air in through both card cages and the power

supply bay to maintain acceptable operating temperatures for the internal components.

Safety Guidelines

Safety with Electricity

The line cards, RP, switch fabric cards, 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.

Tools and Parts Required

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 component, 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 component to the factory, immediately place it in a static shielding

bag to avoid ESD damage to the component.

•The wrist strap only protects the component 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 remove and replace the card cage assembly:

•ESD-preventive wrist strap

•1/4-inch flat-blade screwdriver

•3/16-inch flat-blade screwdriver

•10-mm nutdriver

•Antistatic mat

•The replacement card cage assembly (Product Number: GSR12-CARDCAGE=)

You must remove all cards and power supplies from the old card cage assembly and install them in

the replacement card cage assembly. The replacement card cage ships with a new air filter installed.
