Replacing Fan Modules
Caution
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.
Step 1
Slide the server out the front of the rack far enough so that you can open the fan compartment cover on top of the chassis.
You might have to detach cables from the rear panel to provide clearance.
Caution
If you cannot safely view and access the component, remove the server from the rack.
Step 2
Open the hinged cover:
a) If the cover latch is locked, use a screwdriver to turn the lock 90-degrees counterclockwise to unlock it.
b) Lift on the end of the latch that has the green finger grip. The cover is pushed back as you lift the latch.
c) Open the hinged cover.
Step 3
Grasp and squeeze the fan module release latches on its top. Lift straight up to disengage its connector from the
motherboard.
Step 4
Set the new fan module in place.
The arrows printed on the top of the fan module must point toward the rear of the server.
Note
Step 5
Press down gently on the fan module to fully engage it with the connector on the motherboard.
Step 6
Close the hinged cover:
a) With the latch in the fully open position, close the hinged cover.
b) Press the cover latch down to the closed position. The cover is pushed forward.
c) If desired, lock the latch by using a screwdriver to turn the lock 90-degrees clockwise.
