Remove the Motherboard
Note -
When replacing the motherboard, remove the SC PROM from the old motherboard and
install that component on the new motherboard. The SC PROM contains the system host ID and
MAC address. Transferring this component preserves system-specific information. The SP is
built into the motherboard, not on a separate card as on some earlier servers.
1. Prepare for servicing.
a. Attach an antistatic wrist strap.
b. Power off the server and unplug power cords from the power supplies.
See “Removing Power From the Server” on page 50 .
c. Remove the server from the rack.
See “Remove the Server From the Rack” on page 58 .
d. Remove the top cover.
See “Remove the Top Cover” on page 59 .
2. Remove the air baffle.
See “Remove the Air Baffle” on page 60 .
3. Remove all PCIe cards.
See “Remove a PCIe Card or Filler” on page 104 .
Always remove transceivers from a PCIe card before removing the card from the server.
Keep track of which slot each PCIe card was in so you can return them to their original
positions.
4. Remove the SC PROM from the motherboard.
