To remove the system board from the system board tray, perform the following
steps. (If you are replacing the system board, you may want to remove the
expansion cards, memory, processors, and processor guidesand install them
on the replacement system board.)
1. Remove the system board assembly.
2. Note the slot numbers of any expansion cards you are migrating to the
new system board so that you can install them in the same slots on the
new board.
3. Remove the system board components you are migrating to the new sys-
tem board.
4. Loosen the thumbscrew securing the system board to the tray (see
Figure 4-32).
5. Slide the system board to the left as shown in Figure 4-32 (toward the
inner expansion-card guide brackets) about a half inch to clear the chassis
hooks, and remove the board.
If you are replacing the system board, install any components you removed
from the old system board onto the replacement board. To retain the same
system configuration and appropriate resource sharing, install PCI expansion
cards in the same slots they were in on the old system board. Verify that the
jumper settings on the new system board are correct.
