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

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
