Chapter 5 Removal and Replacement Procedures
Removing and Replacing the Fan Assembly
Step 3
Grasp the fan assembly with both hands and pull it outward; rock it gently if necessary to unseat the
power connector from the backplane.
Warning
When removing the fan tray, keep your hands and fingers away from the spinning fan blades. Let the
fan blades completely stop before you remove the fan tray.
Step 4
Pull the fan assembly clear of the chassis, and put it in a safe place.
Installing the Fan Assembly
Perform these steps to install the new fan assembly:
Step 1
Hold the fan assembly with the fans facing to the right and the FAN STATUS LED at the bottom (see
Figure 5-117
for the Cisco 7603 router,
Figure 5-118
for the Cisco 7603 router,
Figure 5-119
for the
Cisco 7604 router,
Figure 5-120
for Cisco 7606 router,
Figure 5-121
for Cisco 7606-S router, and
Figure 5-122
for the Cisco 7613 router.) For the Cisco 7609 router and the Cisco 7609-S router, hold the
fan assembly so that the handle is at the top of the assembly (see
Figure 5-124
).
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 chassis guides.
Step 3
Push the fan assembly into the chassis until the power connector seats in the backplane and the captive
installation screws make contact with the chassis.
Step 4
Tighten the captive installation screws.
Note
On the Cisco 7609 router and the Cisco 7609-S router, fold the cable guide up and tighten the
two captive installation screws at the top of the chassis (see
Figure 5-123
).
