Removing Add-In Cards
1 Disconnect any external and internal cables 
attached to the card.
2 Remove the screw on the bracket of the card 
you are replacing.
3 Hold the metal bracket and the far top 
corner of the card. Carefully remove the 
card by pulling the card straight out of the 
expansion slot.
Replacing Add-In Cards

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.
