Procedure
This procedure explains how to remove a standard card and a card that includes a booster cable. 
Before you can remove either type of card, however, you must first loosen the two captive screws 
that secure the PCI bracket to the enclosure and remove the bracket. 
Warning: When removing or installing a card, handle it only by the edges. Do not touch its 
connectors or any of the components on the card. Lift the card straight out from the connector 
to remove it, and insert it straight into the connector to install it. Do not rock the card from side 
to side and don’t force the card into the slot. Once the replacement card is installed, pull on it 
gently to check that it is properly connected.

Standard Card
Release the small locking clip at the front of the card’s logic board connector by pushing the 1. 
clip up toward the media shelf.
Holding the card by the top corners, pull up the card and remove it from its expansion slot.2.  
Replacement Note: Align the card’s connector with the expansion slot and press until the 
connector is inserted all the way into the slot. If you’re installing a 12-inch card, make sure the 
card engages the appropriate slot in the PCI card guide.
Don’t rock the card from side to side; instead, press the card straight into the slot. • 
Don’t force the card. If you meet a lot of resistance, pull the card out. Check the connector • 
and the slot for damage or obstructions, then try inserting the card again.
Pull the card gently to see if it is properly connected. If it resists and stays in place and its • 
gold connectors are barely visible, the card is connected.
