6-4 System Fans
Seven 4-cm heavy duty counter-rotating fans provide the cooling for the 8017R-
TF+/8017R-7FT+. Each fan unit is actually made up of two fans joined back-to-
back, which rotate in opposite directions. This counter-rotating action generates
exceptional airfl ow and works to dampen vibration levels. It is very important that
the chassis top cover is properly installed and making a good seal in order for the
cooling air to circulate properly through the chassis and cool the components. See
Figure 6-3.
System Fan Failure
Fan speed is controlled by system temperature via IPMI. 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).
1. Remove the top chassis cover while the system is still running to determine
which of the fans has failed. Then turn off the system and remove the AC
power cord from the system.
2. Unplug the fan cable from the serverboard.
3. Unscrew the failed blower fan from the chassis and pull it completely out from
the serverboard.
4. Replace the failed fan with an identical 4-cm, 12 volt fan (available from
Supermicro: p/n FAN-0101L4).
5. 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 direc-
tion as the arrows on the other fans.
6. Reposition the fan housing back over the two mounting posts in the chassis,
then reconnect the fan wires to the same chassis fan headers you removed
them from.
7. Power up the system and check that the fan is working properly and that the
LED on the control panel has turned off.
8. Finish by replacing the chassis cover.
