Fan Tray
The fan tray unit contains eight 12V fans which pull air from the front of the unit through a series of
air vents. A curved frame, housing the front panel display unit, attaches to the front of the fan tray
unit and is considered an integral part of the fan tray unit. This curved frame must not be removed
at any time.
NOTE: If the fan tray unit is removed for more than two minutes, the device might shut down.
Removing and Replacing the Fan Tray
To remove the fan tray:
1. Remove the bezel from the unit, as described in
Removing and Replacing the Bezel.
2. With a Phillips-head screwdriver, remove the two screws that attach the fan tray assembly to
the chassis, as shown in
Figure 4–5, step 2.
3. Grasp the front of the fan tray assembly, and pull the tray firmly but smoothly towards you to
disengage it from the PC connector inside the unit.
