Chapter 7 Maintaining the Cisco Catalyst 5500 Multiswitch Router
Replacing Hardware Components
Note The fan assembly is designed to be removed and replaced while the system is operating without
presenting an electrical hazard or damage to the system.
Step 1 Locate the fan assembly to the left of the card cage (see Figure 7-13).
Step 2 Loosen the two captive installation screws by turning them counterclockwise.
Step 3 Grasp the fan assembly with both hands and pull it outward, joggling it if necessary to unseat it from the
backplane. Pull it clear of the chassis and place it in a safe location.
Installing the Fan Assembly
Perform the following steps to install the new fan assembly:
Step 1 Hold the fan assembly with the fans facing to the right.
Step 2 Place the fan assembly into the front chassis cavity so that it rests on the chassis, and then lift the fan
assembly up slightly, aligning the top and bottom guides.
Step 3 Push the fan assembly into the chassis until the captive installation screws meet the chassis.
Step 4 Tighten the captive installation screws by turning them clockwise.
