the cooling air through the system and expels the hot air.

Fan Failure
Under normal operation, the two chassis fans, the exhaust fan and the
primary power supply fan run continuously.

can disable the alarm with the reset button on the back of the power sup-
ply.
The system can operate with only one power supply fan, but you
should replace the power supply as soon as possible.
cooling fans are hot-swappable - you can replace them without powering
down the system (the exhaust fan is not hot-swappable).
Replacing System Fans
1.
Identifying the failed fan:
Inspect the back of the chassis to see if the 12-cm exhaust fan has
failed. You must power down the system to replace this fan. To replace
a failed chassis cooling fan, you must first remove the top/left chassis
cover.
Remove the two screws from the back lip of the top/left cover.
Push in the release tab on the cover and push the cover toward the rear
of the chassis until it stops (after moving about ½ inch). Then lift the
cover up and off the chassis and see which fan has failed.
2.
Removing a hot-plug fan housing:
Depress the locking tab on a chassis cooling fan and pull the unit straight
out by the handle. The fan wiring for these two fans has been designed
to detach automatically. The 12-cm exhaust fan is also in a housing that
can be removed from the chassis (not hot-swappable - see Figure 6-3).
3.
Installing a new system fan:
Replace the failed fan with an identical one (available from Supermicro).
After the new fan has been installed, reassemble the fan housing and
plug the housing back into its slot. You should hear it click into place
when fully inserted. Check that the fan is working properly. Finish by
replacing the top/left side chassis panel.
