installing add-in cards
At some point, you may want to add a PCI or AGP card to the computer to
accommodate a new component, such as a scanner, or to upgrade an existing
card.
WARNING: Do not overload the system by installing add-in cards
that draw excessive current. The system is designed to provide
2 amps (average) of +5 V power for each board/card in the
computer. The total +5 V current draw in a fully loaded system
(one with all add-in card slots filled) must not exceed the total
number of slots multiplied by 2 amps.
To add or replace an add-in card:
1
Turn off the computer and all peripherals.
2
Disconnect the modem/telephone cable.
3
Disconnect the power cord and all other attached cables (such as the
keyboard, mouse, and monitor).
4
Remove the side panel (see “removing the side panel” on page 131).
5
Gently lay the computer on its side.
6
To prepare an empty card slot for a new card, loosen the screw of the
expansion slot cover of the empty slot (
E
). Remove the expansion slot cover of
the empty slot.

WARNING: Be careful of the sharp edges on the expansion slot
cover.
