6-3 System Fans and Air Shroud
Six 8-cm heavy duty fans provide the cooling for the 2041M-32R+/2041M-T2R+.
The fans are paired back to back to provide redundancy and to generate excellent
airfl ow. 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.
See Figure 6-2.
System Fan Failure
Fan speed is controlled by system temperature via a BIOS setting. 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 while the system is still running to determine which
of the fans has failed. Removing and replacing fans may be performed while the
system is still running.
Replacing System Cooling Fans
1. Removing a fan
Remove the chassis cover. Press the tab on the top of the fan housing of the failed
fan and remove the entire housing unit. The system power need not be shut down
since the fans are all hot-pluggable.
2. Installing a new fan
Replace the failed fan with an identical 8-cm, 12 volt fan (available from Super
Micro: p/n FAN-0099L). Position the new fan at its proper place in the chassis by
fi tting 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 is already
powered on, the fan will activate immediately upon being connected to its header
on the serverboard.
