Chapter 5: Chassis Setup and Maintenance
Three heavy duty fans provide cooling for the chassis. These fans circulate air
through the chassis as a means of lowering the chassis internal temperature.

Replacing a System Fan
1. If necessary, open the chassis while the power is running to determine which
fan has failed. (Never run the server for an extended period of time with the
chassis open.)
2. Power down the system and unplug the power cord from the rear of the
power supply.
3. Remove the failed fan's power cord from the serverboard.
4. Press the fan release tab to lift the failed fan from the chassis and pull it
completely from the chassis.
5. 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.
6. Plug the power cords into the rear of the power supply, power up the system
and check that the fan is working properly before replacing the chassis cover.
