Figure 3-7. Replacing System Fans
Replacing Fans
Five counter-rotating fans circulate air through the chassis to lower the internal temperature.
These fans are designed to be easily changed, with no tools required and no need to remove
any other parts inside the chassis.
Replacing a System Fan
1. If necessary, open the chassis cover as described in section 3.2 while the power is
running to determine which fan requires changing. (Never run the server for an extended
period of time with the chassis open.)
2. Power down the system as described in section 3.1.
3. Remove the failed fan's cable from the connector on the motherboard.
4. Place the new fan into the housing. Make sure that the arrows on the sides of the fan
(indicating air direction) point in the same direction as the arrows on the other fans.
5. Plug the fans' cables into the connectors on the motherboard.
6. Plug the power cord into the rear of the power supply, power up the system, and check
that the fan is working properly. Then, power off the system before replacing the top
cover.
