System Fans
One 10-cm blower fan provides all the cooling needed for the Super-
Server 6011H. The chassis includes air seals under the blower fan and
at the chassis cross section, which separates the drive bay area from
the motherboard area of the chassis to promote better airflow. It is very
important that the air seal is properly installed and making a good seal in
order for the cooling air to circulate properly through the chassis. See
Figure 6-3.
System Fan Failure
The blower fan runs at 3800 RPM. If the fan fails, the ambient air
temperature in the chassis will rise and activate the overheat LED on the
control panel. You will need to power down the system to replace the
blower fan.
Replacing System Cooling Fans
1.
Removing the blower fan:
After turning off the power to the system, first remove the chassis cover
and unplug the fan cable from the motherboard. Lift the blower fan from
the mounting posts and pull it completely out from the motherboard. See
Figure 6-3.
2.
Installing a new blower fan:
Replace the failed fan with an identical 10-cm, 12 volt fan (available from
Supermicro). Position the new fan at its proper place in the chassis, by
fitting the fan onto the fan mounting posts in the chassis. After the new
fan has been installed, plug the fan cable back into the same chassis fan
header on the motherboard from which you removed it. Make sure the air
seal under the fan is properly installed and is creating a good seal.
Power up the system and check that the fan is working properly and that
the LED on the control panel has turned off. Finish by replacing the top
panel of the chassis.
