Replacing Add-In Cards

seated.

n
Be careful of the
sharp edges on the
expansion slot cover.
n
Do not overload the
PC by installing
add-in cards that
draw excessive
current. The chassis is
designed to provide
2 amps (average) of
+5 V power for each
board or card in the
chassis. The total
+5 V current draw in
a fully loaded chassis
(one with all add-in
card slots filled) must
not exceed the total
number of slots
multiplied by 2 amps.
