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

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.

Removing Add-In Cards

1 Disconnect any external and internal cables attached to the card.

2 Loosen 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

1 Insert the new card into the slot and push straight down. Make sure the card is properly seated.

2 Attach the screw to secure the card you have replaced.

3 Connect any internal cables to the card.
