6-3 System Fans
Three 9-cm chassis cooling fans (located in the center of the chassis) provide
cooling airfl ow while three 8-cm exhaust fans expel 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 all chassis fans, exhaust fans and the power supply fans
run continuously. If the system LED indicates a fan failure, you should determine
which fan has failed and replace it. The system fans are hot-swappable and can
be replaced without powering down the system.
Replacing System Fans
Removing a Fan
First locate the failed fan by removing the top/left chassis cover (see Chapter 1.
2 for details). Locate the fan that has stopped working.
Depress the locking tabs on the failed chassis fan. On an exhaust fan, push 2.
down on the colored tab then pull the unit straight out. 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) 1.
Install it in the same position and orientation as the one you removed. A 2.
"click" can be heard when the fan is fully installed.
Check that the fan is working then replace the top/left side chassis panel. 3.
Removing/Installing the Air Shroud
Note: Under most circumstances you won't need to remove the air shroud to perform
service on the system and it should remain in place when the system is running
Depress the tabs at the front and rear of the shroud to unlock it. 1.
Lift it up and out of the chassis (see Figure 6-4). To reinstall, simply position 2.
the air shroud in its proper place and push it in until you hear it click.
