2. Tilt the panel flush against the frame and secure the panel to the chassis with two #10 Phillips screws.

8.1.2 Vented Front Panels

---

Caution - Do not remove the vented front panels by twisting off. Such action may break the panel or fasteners. Always support the panels during removal and replacement.

The three vented front panels all remove in the same manner. They are retained by chassis-mounted ball studs that mate with catches on the panel backside.

To remove the panels:

1. Grasp the panel under the vent on one side and pull out far enough to just disengage the ball studs.

   See Figure 8-2.

2. Repeat this procedure on the other side of the vent to disengage and remove the panel. Set the panel aside.

To replace a panel:

1. Place the panel against the chassis with ball studs aligned with the catches on the panel.

   Tap or press both sides of the panel into place.

8.2.7 Stabilizer Bar

---

Warning - Always extend the stabilizer bar before pulling the disk drive trays out for servicing.

---

The cabinet has six levelling pads. Four pads on the cabinet frame are lowered to touch the floor and prevent the cabinet from rocking. Two levelling pads are part of the stabilizer bar and should not touch the floor.

1. Extend the stabilizer bar fully from the bottom of the cabinet.

   See Figure 8-8.

2. 1 2. Screw the two stabilizer bar levelling pads down until they are /8- to 1/4-inch (3 to 6 mm) above the floor.

   Ensure both pads are at equal heights. This clearance allows the stabilizer bar to slide in and out easily, yet catch the cabinet if it should begin to tilt.
