System Cooling
Up to three fans provide cooling for the system (third fan is optional). The chassis top cover
must
be installed properly and form a tight seal so that the cooling air can circulate properly
through the chassis.
System Fan Failure
Fan speed is controlled by system temperature via IPMI. Replace any failed fan with the
same type and model.
Replacing Fans
Begin by removing power from the system as described in Section 3.1 and removing the
cover as described in Section 3.2.
1. Disconnect the fan power cable from the motherboard and remove the broken fan.
2. Replace the failed fan with an identical 4028mm 13K RPM 4-pin PWM fan (available
from Supermicro).
3. Position the new fan into the space vacated by the failed fan previously removed. An
audible click indicates that the fan is fully installed.
4. Reconnect the fan cables to the motherboard.
5. Reinstall the chassis cover and restore power to the server.
5. Replace the expansion card clip and screw it onto the chassis to hold the expansion
card in place.
6. Reinstall the chassis cover and restore power to the server.
