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).

Product Overview Product Overview 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 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.
PAGE 3
Product Overview Clock and Scheduler Card The Cisco 12012 requires that one clock and scheduler card be installed in the lower card cage. You can add one additional clock and scheduler card for redundancy and to increase the amount of data able to be transferred between line cards. The clock and scheduler card contains the following functionality: • System clock—Sent to all line cards, RP, and switch fabric cards.

Safety Guidelines Lower Card Cage Status LEDs There are no status LEDs on the clock and scheduler card or switch fabric card, and the lower card cage slots are hidden behind the air filter. Status for the lower card cage slots is displayed on five pairs of LEDs located on the alarm card (installed in the rightmost slot in the upper card cage).
PAGE 5
Safety Guidelines 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.
PAGE 6
Tools and Parts Required Preventing Electrostatic Discharge Damage Electrostatic discharge (ESD) damage, which can occur when electronic boards or components are handled improperly, can result in intermittent or complete 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.

Removing and Replacing a Card in the Lower Card Cage Removing and Replacing a Card in the Lower Card Cage The Cisco 12012 supports up to five cards in the lower card cage; two clock and scheduler cards and three switch fabric cards. The lower card cage is located directly behind the air filter tray and an air deflector. To access the lower card cage, you must first lower the air filter tray and raise and secure the air deflector.
PAGE 8
Removing and Replacing a Card in the Lower Card Cage 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 Figure 3.
PAGE 9
Removing and Replacing a Card in the Lower Card Cage Figure 4 To access the cards in the lower card cage, you must first move the air deflector up, out of the way. Pivot the air deflector up and secure it to the top of the lower card cage by turning the air deflector latch knob counterclockwise. (Refer to Figure 4.
PAGE 10
Removing and Replacing a Card in the Lower Card Cage On the card you intend to remove, grasp the card ejector levers and simultaneously pivot both ejector levers ninety degrees inward (away from the sides of the card cage) to unseat the card from the backplane connector. (Refer to Figure 5.
PAGE 11
Removing and Replacing a Card in the Lower Card Cage Note When you install a clock and scheduler card or a switch fabric card in the lower card cage make sure that you keep the card centered in the slot by applying even pressure to both sides of the card carrier as you slide it into the slot. Step 4 Pivot the two card ejector levers out ninety degrees away from the sides of the card carrier.
PAGE 12
Checking the Installation Checking the Installation Complete the following steps to verify that the new clock and scheduler card or switch fabric card is working properly: Step 1 Step 2 Check the following components to make sure that they are secure: • The cards in the lower card cage are fully seated in their slots and the card ejector levers are retracted and latched in the card carriers. • • The air deflector in the lower card cage is down, resting on its stops.
