6-3 System Fans
System cooling is provided by four 8-cm hot swappable midplane fans as well as
two 4-cm counter-rotating fans on each of the server node.
It is very important that the chassis cover is properly installed and making a good
seal for the cooling air to circulate properly through the chassis and cool the
components.
System Fan Failure
Fan speed is controlled by system temperature via IPMI. If a fan fails, the remaining
fans will ramp up to full speed and the overheat/fan fail LED on the control panel
(of the same side as the failed fan) will turn on.
The fans may also be visually inspected for failure. 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.
Replacing Midplane Fans
Replace a failed midplane fan with an identical 4-cm, 12-volt counter-rotating fan
(p/n FAN-0164L4, available from Supermicro). See Figures 6-2 and 6-3.
Replacing Fans
1. Shutdown the system and remove the AC power cord.
2. Open the system cover
3. Remove the failed fan assembly from the midplane and replace its fan with
an identical replacement.
4. Replace the fan assembly back into the chassis midplane.
5. Reconnect the AC power cord and power up the system.
6. Inspect the replaced fan to verify it is working.
7. Replace the cover back on the system.
