Maintenance and Upgrade
Note
The system supports operation with a single fan failure (N+1 fan redundancy), but do not run the system for
an extended amount of time without all fan modules installed. Keep removal and replacement time at three
minutes. Remove and replace one fan module at a time.
Step 1
To remove a fan module, face the rear of the chassis, and grasp the handle of the fan module.
Step 2
Squeeze the handle to disengage the latches on the left and right of the fan module.
Step 3
Pull the fan module out of the chassis.

Step 4
To replace a fan module, hold the fan module in front of the fan slot.
Step 5
Push the fan module into the chassis until it is properly seated and the latches snap 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. See
LEDs.
