Expansion Cards/Graphics Cards (optional)
Location: Certain configurations of desktops may include expansion and/or graphics cards. These
can be found in the rear of the chassis, on the opposite side of the power supply for the Vision
Series configuration. The cards are electrically connected to the motherboard via PCIe slots, and
physically connected to the case.
Type and number of fastenings: One or two Phillips screws.
Tools required: Screwdriver with PH2 bit.
Procedure:
Step 1: Ensure the desktop is off, unplugged, and any potential energy is dissipated.
Step 2: Remove the top
panel from the chassis as indicated in the “Chassis Cover” section of this
manual.
Step 3: Remove the Phillips screws from the rear of the case that was holding the expansion card
in place.
Step 4: Disengage the retaining latch on the PCIe slot (see photo below). This is a critical step and
if not done may damage the slot.
Step 5: With firm, gentle force, pull the card, perpendicular to the motherboard, out of the
attaching PCIe socket. Be careful not to bend the card while still engaged in the PCIe slot.
Reinstallation
Step 6: Ensure the desktop is off, unplugged, and any potential energy is dissipated.
