6-3 System Fans
Four 80-mm chassis cooling fans (located in the center of the chassis) provide
cooling airfl ow. The chassis is fi tted with an air shroud to concentrate the fl ow of
cooling air over the areas of highest generated heat. The fans should all be con-
nected 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 and the power supply fan run continu-
ously. The four chassis cooling fans (not the power supply fan) are hot-swappable
and can be replaced without powering down the system.
Replacing System 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 (available from Supermicro). Install
and reassemble it in 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 properly
and 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.
