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. The chassis fans are hot-swappable and can be replaced without
powering down the system.
Replacing Chassis Fans
1. Identifying the failed fan
To locate and replace a failed chassis fan, begin by removing the top/left chassis
cover (see Chapter 2 for details on removing the cover). Locate the fan that has
stopped working.
2. Removing a hot-plug fan housing
Depress the locking tab on the failed fan: on a chassis fan, puch 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.
3. Installing a new system 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.
Removing the air shroud
Under most circumstances you will not need to remove the air shroud to perform
any service on the system. However, if you wish to temporarily remove it (the air
shroud sould always be in place when the system is operating), please follow this
procedure. Begin by depressing the tabs at the front and rear of the shroud to
unlock it, then 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.
