Removing an Add-in Board
▲

!
CAUTION
Expansion slot covers must be installed on all vacant slots
to maintain the electromagnetic emissions characteristics of
the system and to ensure proper cooling of the system
components.
See Figures 4-10, 4-11, and 4-12.
1. Observe the warnings and cautions on page 3, “Safety Guidelines.”
2. Remove the side cover (page 80).
3. Disconnect any cables attached to the board you are removing.
4. Remove and save the add-in board retaining bracket screw.
5. Holding the board by its top edge or upper corners, carefully rock it
back and forth until the edge connector pulls free. Make sure that you
do not scrape the board against other components.
6. Store the board in an antistatic protective wrapper.
7. Install an expansion slot cover (Figure 4-10) over the vacant slot. The
tapered foot of the cover must fit into the mating slot in the bottom of
the expansion slot frame.
8. Insert the screw you removed earlier, and push the rounded notch up
against the screw. Tighten the screw firmly (6.0 inch-pounds) to
prevent the bracket from interfering with an adjacent one.
9. Replace the side cover (page 81).
10. If you removed an ISA add-in board, run the SCU to configure the
system. For information about running this utility, see Chapter 3,
“Configuring The System.”
