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. The chassis fans are hot-swappable and can be replaced without
powering down the system.

Replacing Chassis Fans

Removing a Fan
1. First locate the failed fan by removing the top/left chassis cover (see Chapter
2 for details). Locate the fan that has stopped working.
2. Depress the locking tabs on the failed chassis fan. On an exhaust fan, push
down on the colored tab then 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
1. Replace the failed fan with an identical one (available from Supermicro)
2. Install it in the same position and orientation as the one you removed. A
"click" can be heard when the fan is fully installed.
3. Check that the fan is working then replace the top/left side chassis panel.
Removing the Air Shroud
Note: Under most circumstances you won't need to remove the air shroud to perform
any service on the system. It should be in place whenever the system is running
1. Depress the tabs at the front and rear of the shroud to unlock it.
2. Lift it up and out of the chassis (see Figure 6-4). To reinstall, simply position
the air shroud in its proper place and push it in until you hear it click.
