6-3 System Fans
Two 8-cm PWM chassis cooling fans (located in the center of the chassis) provide
cooling airfl ow while one 9-cm exhaust fan expels hot air from the chassis.
The fans should all be connected to headers on the serverboard (see Chapter 5).
Each power supply module also has a cooling fan.
Fan Failure
Under normal operation, the chassis fans, the exhaust fan and the power supply fans
run continuously. The chassis fans are located in the two middle housings. They are
hot-swappable and can be replaced without powering down the system.
Replacing Chassis Cooling Fans
Removing a Fan
First locate the failed chassis fan by removing the top/left chassis cover (see
Chapter 2 for details). Locate the fan that has stopped working.
Depress the locking tab on the failed fan: on a chassis fan, push the tab on
the side of the housing inward, on the exhaust fan push down on the colored
tab.
With the tab depressed, pull the unit straight out (see Figure 6-3). The wiring
for these fans has been designed to detach automatically.
Installing a New Fan
Replace the failed fan with an identical one (available from Supermicro)
Install it in the same position and orientation as the one you removed; it
should click into place when fully inserted.
Check that the fan is working then replace the top/left side chassis panel.
