Pull the expansion card straight up from the socket then away from the inside of the chassis to release it from the chassis frame.
  • Page 69 If you are not installing a new expansion card, install an expansion slot cover to close the open slot. CAUTION: After removing an expansion card, you must replace it with a new card or expansion slot cover for proper cooling of internal components during operation. To install a new expansion card, hold the card just above the expansion socket on the system board then move the card toward the rear of the chassis so that the bracket on the card is aligned with the open slot on the rear of the chassis.
