6-3 System Fans
Four 8-cm fans and an air shroud (which channels the air fl ow to the processors)
provide all the cooling needed for the SuperServer 6025B-T/6025B-8. 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 (see instructions in Chapter 2) while the system is
still running to determine which of the fans has failed.
The hot-plug fan will start to function upon connection to its fan header on the
serverboard.
Replacing System Fans
1. Removing a fan
Remove the chassis cover. Press the tabs on the top of the fan housing and move
the fan and its housing. System power does not need to 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 Supermicro,
p/n FAN-0070). 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 power is on, the hot-plug
feature will cause the fan to start immediately upon being connected to its header
on the serverboard.
