Chapter 6: Advanced Chassis Setup
6-5
6-3 System Fans
A 9-cm fan at the front of the chassis provides cool air intake while a 12-cm exhaust
fan at the rear of the chassis pulls the cool air through the system and expels the
hot air. Fan speed is controlled by a setting in BIOS (see page 7-15). The power
supply has two fans: a primary and a secondary (backup).
Fan Failure
Under normal operation, the chassis, the exhaust and the power supply fans all run
continuously. The system must be powered down before replacing either the 9-cm
chassis fan or the 12-cm exhaust fan.
Replacing System Fans
1. Identifying and accessing the failed fan
Inspect the back of the chassis to determine if the 12-cm exhaust fan has failed or
the lower front section of the chassis to check if the 9-cm fan has failed. Power
down the system and remove the left chassis cover by fi rst removing the two screws
from the back lip of the cover. Push the cover toward the rear of the chassis until
it stops (after moving about ½ inch). Then lift the cover out and away from the
chassis.
2. Removing the 12-cm fan
Unplug the fan wires from the header on the serverboard. The fan housing has two
long tabs that protrude through the back of the chassis. Push these two tabs inward
and lift the housing to remove it from its locked position, then lift the housing out of
the chassis (see Figure 6-4).
3. Removing the 9-cm fan
Unplug the fan wires from the header on the serverboard. The housing for the 9-cm
fan is attached to the chassis with a single screw. Remove this screw and lift the
housing out of the chassis (see Figure 6-5).
4. Installing a new system fan
Disassemble the housing and replace the failed fan with an identical one (avail-
able from Supermicro). After the new fan has been installed, reassemble the fan
housing and install it by reversing the removal procedure. Plug the fan wires back
into their header on the serverboard. Finish by replacing the chassis cover, then
restore power to the system. Verify that the replaced fan is working properly.
