Installing and Removing a Fan Module

Installing and Removing a Fan Module

You can hot swap a fan module (N20-FAN5) without causing an electrical hazard or damage to the system.
However, you can only remove one fan module while the system is operating. Removing more than one fan
module could cause overheating.
Note
When a fan is removed, louvers inside the chassis prevent recirculation of air into the system or loss of
cooling. However, you should not leave the chassis for extended periods of time without all fan modules
in place.

Installing a Fan Module

Procedure
Step 1
Hold the fan module with the spring latch at the top of the module.
Step 2
Push the fan module into the chassis until it seats properly and the spring latch snaps into place.
Step 3
Listen for the fans if the chassis is powered on. You should immediately hear it operating. If you do not hear
it, ensure that the fan module is inserted completely in the chassis and the faceplate is flush with the outside
surface of the chassis.
Step 4
Verify that the LED behavior is as expected. See
