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-swappable and can be replaced without powering down the system.
Accessing the Inside of the System
1. If rack mounted, fi rst release the screws that secure the unit to the rack.
2. Grasp the two handles on either side and pull the unit straight out until it
locks (you will hear a "click").
3. There are two screws that secure the cover to the chassis - remove these
fi rst.
4. Locate the latch on the top (side if tower) of the chassis - depress where it
says "push" then lift the latch to release the cover.
5. Lift the cover from the chassis to gain full access to the inside of the server.
Replacing Chassis Cooling Fans
1. First, remove the top/left chassis cover (see Chapter 2 for details on removing
the cover) to locate the fan that has stopped working.
2. Depress the locking tab on the failed fan: on a chassis fan, push 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. Replace the failed fan with an identical one. 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.
