Replacing a System Fan
1. If necessary, open the top rear cover of the chassis while the system is running to locate
the position of the failed fan. Do not run the server for an extended time with the cover
off.
2. Power down as described in Section 3.1.
3. Remove the failed fan's power cable from the motherboard.
4. Lift the failed fan from the fan housing and out of the chassis.
5. Place the new fan into the vacant space in the fan 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 in the same fan housing.
6. Reconnect the fan wires to the same chassis fan headers as the previous fan.
7. Power up the system and check that the fan is working properly before replacing the
chassis cover.
