2.6Reinstalling the Top Cover and Side Panel

If you removed the top cover and side panel as described in the two previous sections,

you probably noticed the panels are a snug fit. The snug fit helps the computer meet

FCC requirements.

Use the following instructions when reinstalling the side panel and top cover:

Side Panel

1.Install the side panel before you install the top cover. The side panel has twelve

small tabs and four screws that hold it in place. To remove the panel, you pushed

it toward the front of the computer, creating about a 1/2" gap between the front lip

of the side panel with the four screw holes and the threaded holes in the cabinet.

2.To reinstall the panel, hang the side panel in the forward position and press down

on the panel, making sure both the top and bottom tabs slide into position.

3.At this point the panel should be in position vertically, but with a 1/2" gap between

the front lip of the side panel with the four screw holes and the threaded holes in

the cabinet.

4.Using the palm of your hand, firmly strike the front edge of the side panel; this will

cause the side panel to slide back into its proper mounting position.

5.Reinstall the four screws.

Top Cover

1.When setting the top cover in position, make sure each tab is aligned with a

corresponding slot on the top of the cabinet. Press the top cover down into

position.

2.Make sure each of the tabs is fully inserted, with the top cover sitting flush on top

of the cabinet.

3.Like the side panel, there will be a gap of about a 1/2" between the front lip of the

top cover with the two screw holes and the threaded holes on the front of the

computer cabinet.

4.Each corner of the top cover has a notched tab designed to hold the cover in its

mounting position. Use the palm of your hand to push the top cover back into

position, which will close the gap between the front lip of the top cover and the

threaded holes in the cabinet.

5.Install the two screws that secure the top cover to the computer cabinet.
