6: Basic Troubleshooting and Chassis Service
System Fan Failure
Fan speed is controlled by system temperature via a BIOS setting. If a fan fails, the remaining fans
will ramp up to full speed and the overheat/fan fail LED on the control panel will turn on. Replace
any failed fan at your earliest convenience with the same type and model (the system can continue
to run with a failed fan). You can remove the top chassis cover while the system is still running to
determine which of the fans has failed.
Replacing System Fans
This section describes how to remove and replace a system fan.
Removing a Fan
1. Slide the server from the rack (if applicable) and remove the chassis top cover.
2. System power does not need to be shut down since the fans are hot-pluggable. Note that the
server should never be run for an extended period of time with the cover removed.
3. Locate and unplug the fan’s power supply cable from the system backplane.
4. Pull the fan housing up and out of the system chassis, see Figure 6-2 on page 49.
5. Push the fan up from the bottom and out of the top of the housing.
Installing a New Fan
1. Install the replacement fan (8-cm, 12 volt fan) into the vacant space in the housing.
Important: Make sure the arrows on the top of the fan (indicating air direction) point in the
same direction as the arrows on the other fans.
2. Re-plug the new fan’s power cable into the backplane connector the old one used.
3. If the system power is on, the hot-plug feature will cause the fan to start immediately upon
being connected to its power source on the backplane.
4. Confirm that the fan is working properly before replacing the chassis cover.
5. Reinstall the chassis top cover and replace the server in the rack as applicable.
