Hot Swapping the 120 mm Fans
The two 120 mm cooling fans are mounted on the top front of the chassis. These
fans can be replaced without shutting down power to the system. If it is a failed
fan, the amber LED will be illuminated on the front panel, and the amber LED on
the failed fan itself will be illuminated. The individual fan LEDs may be seen
through view-ports in the fan covers
Removing the 120 mm Fans
To remove the 120mm fan, complete the following procedure:
1. Slide the server out of the rack far enough to expose the fan-access door on
the top of the chassis.
2. Unscrew the thumbscrew on the front of the fan-access door and lift the
door open. If a fan has failed, the amber LED light is illuminated.
CAUTION Do not leave the door open for an extended time. Cooling of
the system could be reduced
3. Grasp the fan assembly through the finger holes and pull the assembly out.
