Removing and Installing Switch Fabric Cards
Caution On routers with the bezel extender kit installed on the line card and RP card cage front covers, you must
remove the extended front cover from the lower line card and RP card cage before attempting to open
the air filter door. When the extended front cover is mounted on the chassis, the air filter door does not
have adequate free space to open completely.
Caution Be especially careful not to damage the honeycomb screen on the back of the air filter door and on the
inside of the switch fabric card cage. Damaging the honeycomb screen can restrict the air flow and cause
overheating in the router. It can also diminish EMI protection.
Step 3 Identify the card to be replaced in the switch fabric card cage. Grasp the two card ejector levers and
simultaneously pivot both ejector levers 90 degrees (70 degrees for newer switch fabric cards) away from
the front edge of the card carrier to unseat the card from the backplane connector (Figure 5).
Step 4 Touching only the metal card carrier, slide the card out of the slot and place it directly into an antistatic
sack or other ESD-preventive container.
If you plan to return the defective card to the factory, repackage it in the shipping container you received
with the replacement card.
