Procedures
When the bus expander is mounted on top of the computer, its original top cover is placed on
the computer and the computer's top cover is placed on the bus expander. Keep this in mind if
top covers need replaced. Chapter 8 in the Service Handbook lists top cover part numbers with
their original unit.
NOTE
If the bus expander is connected to and mounted on top of the com-
puter, the top cover of the computer with the bus expander attached
can be removed as a single assembly.
If the computer and bus expander are not mounted together, remove the unit's top cover by
following these steps:
1. After the power supply access cover is removed, slide the top cover to the rear and lift up
on the top cover to remove it.
2. To install the top cover, reverse step 1.
