6-3 System Fans
Three 8-cm chassis cooling fans (located in the center of the chassis) provide cool-
ing airfl ow while two 8-cm exhaust fans expel hot air from the chassis. The chassis
is also 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). Each power supply module also has a cooling fan.
Fan Failure
Under normal operation, all three chassis fans, both exhaust fans and the power
supply fans run continuously. The chassis fans and the exhaust fans are hot-swap-
pable and can be replaced without powering down the system.
Replacing Chassis Cooling Fans
First, remove the top/left chassis cover (see Chapter 2 for details on removing 1.
the cover) to locate the fan that has stopped working.
Depress the locking tab on the failed fan: on a chassis fan, push the tab on 2.
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.
Replace the failed fan with an identical one. Install it in the same position 3.
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 should 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. 1.
Lift the air shroud up and out of the chassis (see Figure 6-4). 2.
To reinstall, simply position the air shroud in its proper place and push it in 3.
until you hear it click.
