4.7 System Fans
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
system as a means of lowering the system's 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 System Fans
Replacing Mid-Chassis Fans
1. Determine which fan has failed. Because the fans are hot-swappable, the system 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 direction as the arrows on
the other fans. As soon as the fan is connected, it will begin working.
