6-3 System Fans
Four 9-cm chassis fans, an air shroud and two 8-cm rear exhaust fans
provide all the cooling needed for the 6034H-X8R. It is very important that
the chassis top cover is properly installed in order for the cooling air to
circulate properly through the chassis and cool the components.
System Fan Failure
If a fan fails, the ambient air temperature in the chassis will rise and acti-
vate the overheat LED on the control panel. Replace any failed fan immedi-
ately. The hot plug fans will start to function upon connection to its fan
header on the X6DH8-XG2 serverboard.
Replacing System Fans
1. Removing a fan:
Remove the chassis cover and visually inspect the system to see which
fan has failed. Hold the failed fan on both sides and lift while pressing in
on the tab to remove the entire housing (see Figure 6-2). The fan wiring
will detach automatically. System power can remain on since the 9-cm
chassis cooling fans are hot-pluggable.
2. Installing a new fan:
Remove from the housing and replace the failed fan with an identical 9-
cm, 12 volt fan (available from Supermicro, p/n FAN-0064). Slide the
housing into the fan mounting rails and push until you hear a click. The
fan wiring will attach automatically. If the system power is on, you may
verify that the fan will starts immediately upon being connected to its
header on the serverboard.
Replacing Exhaust Fans
1. Removing a fan:
Visually inspect the back of the chassis to see which fan has failed.
Power down the system and follow the same removal procedure as
described for the chassis fans (above).
2. Installing a new fan:
Remove from the housing and replace the failed fan with an identical 8-
cm fan (available from Supermicro, p/n FAN-0062). Follow the same
installation procedure as described for the chassis fans (above). Re-
store power to the system and check that the fan is working.
