3-8 Disassembly and Reassembly
Replacing the Top Cover
Replace the top cover as follows:
Note:
Replace both side covers before replacing the top
cover.
1.
Replace both side covers (see “Replacing the Side Covers”).
2.
Line up the top cover tabs with the cutaway on the top of the chassis. The
front edge of the cover should be about one-half inch behind the front of the
chassis. The rear edge of the cover should be held higher than the front edge.
See the following figure.
Aligning the Top Cover
A - Chassis Cutaway B - Top Cover Tabs (on underside of cover)
C - Top Cover
Note:
Although the figure shows the system without a
side cover, both side covers must be replaced before the top
cover can be replaced.
3.
Slide the cover forward to meet the front panel as you lower the rear edge.
The top cover should slide over the tops of the side covers.
Note:
The cover fits tightly. If the cover does not slide
all the way to the front panel, make sure that the tabs under
the top cover are aligned with the cutaway on the top of the
chassis and that the top cover is over the tops of the side
covers.
