Figure 7-4. Installing the Option Card in an Expansion Slot
Check the board's alignment to make sure it is straight and
level. If necessary, move the board slightly to align the hole in
the top of the mounting bracket over the screw hole in the
main system unit's rear panel flange. Install the hold down
screw that you removed earlier.
Reconnect any internal cables that were disconnected earlier. If
you have a problem making the cables reach their connectors,
you may have to move the board you just installed to another
slot. If any external equipment is used with the expansion
board, connect it to the board's rear panel connector(s),
following the instructions given with the product.
See the expansion card's manual for any switches or jumpers
to be set.
When the installation of the board is completed, close the
main system unit cabinet as described previously.
