Pcie Expansion Cards; Motherboard Battery - Supermicro SuperWorkstation SYS-531AD-I User Manual

3.7 PCIe Expansion Cards

The SYS-531AD-I can accommodate up to two PCIe 5.0 x16 slots (supporting x16 or x8/x8)
and two PCIe 3.0 x1 expansion cards. Install your graphics card into a PCIe expansion slot.
Note: Slots 4 and 7 share a x16 link. When both slots are populated, they will both
run at x8. If only slot 7 is populated, it will run at x16.
Installing an Expansion Card
Begin by removing power
cover as described in Section 3.2.
1. Remove the shield for the PCIe 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.

3.8 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
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.
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. Please comply with the regulations set up by your local
hazardous waste management agency to dispose of your used battery properly.
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).
