6-3 System Fans
Three 8-cm hot-swap fans provide the cooling for the SuperServer 5025M-UR. It
is very important that the chassis top cover is properly installed and making a good
seal 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.
Replacing System Fans
1. Removing a fan
Remove the chassis cover. Press the tabs on the sides of the fan to unlock and
remove the fan and its housing. The fan's power connections will automatically
detach. System power does not need to be shut down since the fans are hot-plug-
gable.
2. Installing a new fan
Replace the failed fan with an identical 8-cm, 12 volt fan (available from Supermicro,
p/n FAN-0094L). Position the new fan into the space vacated by the failed fan previ-
ously removed. A "click" can be heard when the fan is fully installed in place and
the power connections are made. If the system power is on, the hot-plug feature
will cause the fan to start immediately upon being connected to its header on the
motherboard.
