Six heavy-duty fans provide cooling for the chassis. Four system fans are located in
the mid-section of the chassis with two exhaust fans in the rear. These fans circulate
air through the chassis as a means of lowering the chassis internal temperature.
The fans come pre-installed to the chassis. Each fan is hot-swappable and can be
replaced without removing any connections.

Replacing Mid-Chassis Fans
1. Determine which fan has failed. Because the fans are hot-swappable, the
chassis does not need to be powered-down.
2. Press the fan release tab and lift the failed fan from the chassis. Mid-chassis
fans must be pulled straight out of the chassis.
3. Place the new fan into the vacant space in the housing while making sure the
arrows on the top of the fan (indicating air direction) point in the same direc-
tion as the arrows on the other fans. As soon as the fan is connected, it will
begin working.
