System Fan Failure
Fan speed is controlled by system temperature via a BIOS setting (Fan Speed
Control Modes). If a fan fails, the remaining fan 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).
Remove the top chassis cover while the system is still running to determine which of
the fans has failed. Then power down the system before replacing a fan. Removing
the power cord(s) is also recommended as a safety precaution.
Replacing System Fans
1.
After determining which fan has failed, turn off the system power.
2.
Unplug the fan wiring from the serverboard and remove the failed fan.
3.
Press the fan release tab to lift the failed fan from the chassis and pull it
completely from the chassis.
4.
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.
5.
Power up the system and check that the fan is working properly before re-
placing the chassis cover.
