System Fans

Three 9-cm chassis cooling fans (located in the center of the chassis) provide cool-
ing airfl ow and three 8-cm exhaust fans expel the hot air from the chassis. 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 connected to headers on the
serverboard (see Chapter 5). The power supply module also has a cooling fan.
Fan Failure
Under normal operation, all three chassis fans and the power supply fan run continu-
ously. The chassis cooling fans and exhaust fans (not the power supply fans) 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
Inspect the fans to see which has stopped working, then depress the locking tab
on the failed 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.
