Removing the Fan Tray
To remove the fan tray:
Caution: Do not use the fan tray handle to carry the fan tray assembly. Use the
handle only to pull the tray out of the chassis.

Place a flathead screwdriver in the groove where the top bezel meets
the chassis on the top of the system, and lever the top bezel off the
front of the system.
2
With a flathead screwdriver, loosen the four captive screws located at
the corners of the fan tray.
Warning: Do not place your fingers near the fans when removing the fan tray. The
blades may still be moving.

Pull the fan tray halfway out of the shelf.
Warning: Slowly slide the fan tray out of the chassis. The tray has no stops to
prevent it from sliding all the way out.

Pull the tray out of the chassis.
Installing the Fan Tray
To install the fan tray:

guides of the fan tray compartment; push toward the back of the
chassis halfway, and stop.

Alternate between screws when tightening them to ensure that the
electrical connectors at the back of the tray fit tightly.
