6-3 System Fans
Four 8-cm fans provide all the cooling needed for the SuperServer 6021H.
It is very important that the chassis top cover is properly installed and has
a good seal for the cooling air to circulate properly through the chassis.
See Figure 6-3.
System Fan Failure
The fans run at 3400 rpm. If a fan fails, the ambient air temperature in the
chassis will rise and activate the overheat LED on the control panel. Re-
place any failed fan immediately. The hot plug fans will start to function
upon connection to its fan header on the P3TDER motherboard.
Replacing System Cooling Fans
1. Removing a fan:
Remove the chassis cover. Press the tabs on the top side of the fan
housing and remove the fan and its housing. The system power need
not be shut down since the fans are all hot-pluggable on the P3TDE6
motherboard.
2. Installing a new fan:
Replace the failed fan with an identical 8-cm, 12 volt fan (available from
Supermicro). Position the new fan at its proper place in the chassis, by
fitting the fan with its housing onto the fan mounts in the chassis. A
"click" can be heard if the fan in its housing is properly installed. If the
system power is on, the hot-changeable fan feature enables the fan to
start immediately upon being connected to its header on the P3TDER
motherboard.
