Replacing the LH 3000r Covers

CAUTION
Do NOT operate the NetServer for more than thirty minutes
with any cover (including power supplies and disk drives)
removed. Otherwise, damage to system components may
result due to improper cooling airflow.
The two large covers (Covers 1 and 3) with handles are interchangeable. To
replace them:
1. Insert the two metal tabs, at the end opposite the handle, into the two
openings at the top and bottom corners of the chassis. Hold the cover in
place, but do not slide the tabs in completely yet.
2. Align the four, widely-spaced, metal tabs on the cover's long, top edge
against the leftmost edge of the four widely-spaced openings on the top of
the chassis.
3. Hold the top of the cover in this position with one hand, while pressing the
bottom edge of the cover with the other hand until the cover is completely
flush against the chassis.
4. Gently slide the cover until the shorter edge (no handle end) snaps into
place.
5. Tighten the thumbscrew at the front of the top cover.
6. Check that the four closely-spaced metal tabs are in their four openings at
the rear of the HP NetServer. The cover is secure when all edges are flush
against the chassis and you cannot easily shift it.
Repeat for the other side cover.
7. For the top cover (2), insert the four metal tabs, at the end opposite the
handle, under the flange at the rear of the chassis.
8. Press the top cover back to the rear of the chassis, then slide it to the left to
engage the five tabs on the left side of the cover. The cover can then be
moved backward allowing the thumbscrew to be tightened.
9. Replace the bezel by placing the two tabs at the bottom of the bezel into
the corresponding slots on the chassis and snapping the bezel into position
at the top of the chassis.
