Note

The chassis is designed to have all fan modules in place and operating at all times. Do not leave the fan module

bay empty for longer than is necessary to replace it with a new fan module.

Step 1

To remove a fan module, face the rear of the chassis, and hold the handle of the fan module.

Step 2

Press down on the spring latch at the top of the fan module.

Step 3

Pull the fan module out of the chassis.

Step 4

To install a new fan module, hold the fan module with the spring latch at the top of the module.

Step 5

Push the fan module into the chassis until it is properly seated and the spring latch snaps into place.

If the system is powered on, listen for the fans. You should immediately hear the fans operating. If you do not hear the

fans, make sure the fan module is inserted completely into the chassis and the faceplate is flush with the outside surface

of the chassis.

Step 6

Verify that the fan is operational by checking the fan module LED. It takes about a minute for the Fan LED to be updated.

See

Fan Modules, on page 28

for a description of the fan module LEDs.
