Optional Fan
System Fan Failure
Fan speed is controlled by system temperature via a BIOS setting. 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 cords is also recommended as a safety precaution.
Replacing System Fans
1. After determining which fan has failed, turn off the power to the system.
2. Unplug the fan cable from the serverboard and remove the failed fan from the
chassis.
3. Replace the failed fan with an identical 4-cm, 12 volt fan (available from
Supermicro: p/n FAN-0086L4).
4. Push 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
direction as the arrows on the other fans.
