Replacing Fan Modules
The four hot-swappable fan modules in the server are numbered as shown in Figure 3: Serviceable Component
Locations Inside the Main Chassis, on page 5. Each fan module contains two fans.
There is a fault LED on the top of each fan module. This LED lights green when the module is correctly seated
and is operating OK. The LED lights amber when the module has a fault or is not correctly seated.
Tip
You do not have to shut down or remove power from the server to replace fan modules because they are hot-
swappable. However, to maintain proper cooling, do not operate the server for more than one minute with
any fan module removed.
Caution
Step 1 Remove an existing fan module:
a) Slide the server out the front of the rack far enough so that you can remove the top cover. You might have to detach
cables from the rear panel to provide clearance.
If you cannot safely view and access the component, remove the server from the rack.
Caution
b) Remove the top cover from the server as described in Removing the Server Top Cover, on page 37.
c) Grasp and squeeze the fan module release latches on its top. Lift straight up to disengage its connector from the
motherboard.
Step 2 Install a new fan module:
a) Set the new fan module in place. The arrow printed on the top of the fan module should point toward the rear of the
server.
b) Press down gently on the fan module to fully engage it with the connector on the motherboard.
c) Replace the top cover to the server.
d) Replace the server in the rack.
