Removing and Replacing the Fan Assembly
This section describes how to remove and replace fan assemblies for the Cisco 7600 series router. A
flat-blade or number 2 Phillips-head screwdriver is required to perform this procedure.
Note The Cisco 7609 router and Cisco 7609-S router use redundant fan assemblies. The fan assemblies are
installed one on top of the other.
Removing the Fan Assembly
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.
Perform these steps to remove the existing fan assembly:
Step 1 Locate the fan assembly. (See Figure 5-117 for the Cisco 7603 router, Figure 5-118 for the Cisco 7603-S
router, Figure 5-119 for the Cisco 7604 router, Figure 5-120 for the Cisco 7606 router, Figure 5-121
for the Cisco 7606-S router, Figure 5-122 for the Cisco 7613 router, and Figure 5-124 for the Cisco
7609 router and the Cisco 7609-S router.)
Note On the Cisco 7609 router, the fan assembly is located behind the cable management system. You
must first loosen the two captive installation screws located at the top of the cable management
system and fold the cable guide down to access the fan assembly (see Figure 5-123).
Step 2 Loosen the two captive installation screws by turning them counterclockwise.
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.
