PCI-e Expansion Cards
The 5039AD-I can accommodate up to seven PCI-e expansion cards. Install your graphics
card into a PCI-e expansion slot.
Installing an Expansion Card
Begin by removing power from the system as described in Section 3.1 and removing the
cover as described in Section 3.2.
1. Remove the shield for the PCI-e slot that you wish to populate. Verify that the card you
are installing is supported by the slot.
2. Seat the card firmly into the slot by pushing down with your thumbs evenly on both
sides of the card.
3. Use the thumb screw to secure the expansion card bracket to the rear of the chassis.
Motherboard Battery
The motherboard uses non-volatile memory to retain system information when system power
is removed. This memory is powered by a lithium battery residing on the motherboard.
Replacing the Battery
Begin by removing power from the system as described in Section 3.1 and removing the
cover as described in Section 3.2.
1. Push aside the small clamp that covers the edge of the battery. When the battery is
released, lift it out of the holder.
2. To insert a new battery, slide one edge under the lip of the holder with the positive (+)
side facing up. Then, push the other side down until the clamp snaps over it.
Warning: There is a danger of explosion if the onboard battery is installed upside down (which
reverses its polarities). This battery must be replaced only with the same or an equivalent
type recommended by the manufacturer (CR2032).
Note: Handle used batteries carefully. Do not damage the battery in any way. A damaged
battery may release hazardous materials into the environment. Do not discard a used battery
in the garbage or a public landfill. Comply with the regulations set up by your local hazardous
waste management agency to dispose of your used battery properly.
