Chapter 5: Chassis Setup and Maintenance
Five heavy duty fans provide cooling for the chassis. Three fans are located in the
front of the chassis with two 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.
5-8 System
Fans
To replace a system fan:
1. Open the chassis cover and determine which fan has failed. Because the fans
are hot swappable, the chassis does not have to be powered down.
2. Press the fan release tab and lift the failed fan from the chassis. Front fans
must be pulled straight up. Rear fans must be tilted forward and then pulled
out of the housing.
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.
