6.With one person grasping each side of the DEU slide it out the front of the tower cabinet.

!WARNING

A minimum of two persons is required when performing this step.

7.Place the DEU on a flat clean surface.

8.Remove the fan assemblies (see Figure 4-74, A) from the DEU chassis. Squeeze the fan assembly latches (Figure 4-74, B) towards each other while lifting the assembly up and away from the DEU. Remove both fan assemblies and set them aside.

9.Remove the two screws securing the top cover to the rear of the DEU chassis. See Figure 4-74.

10.Slide the top cover towards the rear of the DEU chassis until its tab fasteners unlock (see Figure 4-74. Lift the top cover up and away from the chassis.
