6-3 System Fans
Four 8-cm chassis cooling fans (located in the center of the chassis) pro-
vide cooling airflow while two 8-cm exhaust fans expel hot air from the
chassis. The chassis is also fitted with an air shroud to concentrate the
flow of cooling air over the areas of highest generated heat. The fans
should all be connected to headers on the serverboard (see Chapter 5).
The power supply module also has a cooling fan.
Fan Failure
Under normal operation, all four chassis fans, both exhaust fans and the
power supply fan run continuously. The four chassis fans and the two
exhaust fans are hot-swappable and can be replaced without powering
down the system.
Replacing Chassis Cooling 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).
2 . Removing a hot-plug fan housing
Depress the locking tab on a chassis cooling fan and pull the unit straight
out by the handle (see Figure 6-3). The fan wiring for these fans has been
designed to detach automatically.
3. Installing a new system fan
Replace the failed fan with an identical one (Supermicro p/n FAN-0072).
Install it in (and then reassemble) the fan housing, then plug the housing
back into its slot; 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.
