Chapter 6: Advanced Chassis Setup
6-3
6-3 System Fans
Seven 4-cm heavy duty counter-rotating fans provide the cooling for the 8016B-
6F/8016B-TF. Each fan unit is actually made up of two fans joined back-to-back,
which rotate in opposite directions. This counter-rotating action generates excep-
tional air ow and works to dampen vibration levels. 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 fan 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. Then power down the system before replacing a fan. Removing the power
cord(s) is also recommended as a safety precaution.
Replacing System Fans
Removing a fan
After turning off the power to the system, rst remove the chassis cover and unplug
the fan cable from the serverboard. Unscrew the failed blower fan from the chassis
and pull it completely out from the serverboard.
Installing a new fan
Replace the failed fan with an identical 4-cm, 12 volt fan (available from Supermicro:
p/n FAN-0101L4). Push the new fan into the vacant space in the housing while mak-
ing 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.
