System Fans
Five 40-mm fans provide the cooling for the 6014P-T/6014P-TR. Each fan unit is
actually made up of two fans joined back-to-back, which rotate in opposite direc-
tions. This counter-rotating action generates exceptional airfl ow and works to
dampen vibration levels. These fans can adjust their speed according to the heat
level sensed in the system, which results in more effi cient and quieter fan operation.
Fan speed is controlled by a setting in BIOS (see page 7-16). Each fan in a set
has its own separate tachometer.
It is very important that the chassis top cover is properly installed for the airfl ow to
circulate properly through the chassis and cool the components.
System Fan Failure
If a fan fails, the remaining fans will ramp up to full speed and the overheat/fan
fail LED on the control panel will turn on. Replace any failed fan at your earliest
convenience with the same type and model (the system can continue to run with
a failed fan). Remove the top chassis cover (see instructions on p. 2-8) while the
system is still running to determine which of the fi ve fan units has failed. Then
power down the system before replacing a fan. Removing the power cord(s) is
also recommended as a safety precaution.
Replacing System Cooling Fans
1. Removing a fan
After turning off the power to the system, fi rst remove the chassis cover (refer to
page 6-7) and unplug all the fan cables from the motherboard. Grasp the rectan-
gular housing that holds all the fan units and lift it out of the chassis (see Figure
6-2). Push the failed fan out through the bottom of the fan housing.
2. Installing a new fan
Replace the failed fan with an identical 40-mm, 12 volt fan (available from
Supermicro: p/n FAN-0079). Push the new fan into the vacant space in the housing
while making sure the arrows on the top of the fan (indicating air direction) point
in the same direction as the arrows on the other fans. Reposition the fan housing
back over the two mounting posts in the chassis, then reconnect the fan wires to
the same chassis fan headers you removed them from. 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 chassis cover.
