To avoid damaging EMI strips, do not
slide the cover back much more than
the 1-inch implied here.
You do not need to remove the
internal board support panels, if you
do not need to access the boards.
Installing the Top Cover
1. Before replacing the top cover, make sure no tools or
loose parts have been left inside the system chassis.
2. Make sure all option boards are firmly seated in
their respective slots and that all interior cables are
properly connected.
3. Ensure that both side panels are installed see
Installing a Side Panel later in this chapter.
4. Lower the cover straight down and over the top of
the chassis with the front edge about 1 inch back
from the edge of the front bezel (front cover). The
sides of the cover should be outside the chassis
metal.
