System Board
If you need to replace your workstation’s system board, you must swap the DIMMs and the
processor modules from the old system board to the new one. See the System Board Manual for
connector and socket locations.
To remove the system board:
WARNING
The system is always on when connected to AC power. Before performing this
task, disconnect the system’s power cord from its AC power outlet.
1.
Lay the chassis down on its right side.
2.
Note the locations where all cables are connected to the system board, and then disconnect all
cables from the system board.
3.
Note the locations of the expansion cards, remove them, and place the cards on an antistatic
surface. See the previous procedures in this chapter for more information.
4.
Remove the DIMMs and the processor modules and place them on an antistatic surface. See
the previous procedures in this chapter for more information.
5.
Remove the jackscrews on all external port connectors.
6.
Remove the screws and the plastic rivets on the processor retention modules, and remove the
retention modules from the chassis.
7.
Remove the 13 screws from the system board.
8.
Lift the system board out of the chassis and place it on an antistatic surface.
To install a new system board:
WARNING
The system is always on when connected to AC power. Before performing this
task, disconnect the system’s power cord from its AC power outlet.
1.
Place the new system board into the chassis and align all mounting holes.
2.
Install the jackscrews on all external port connectors.
3.
Loosely install the remaining screws on the system board, except those for the processor
retention modules. Do not tighten the screws yet.
4.
Mount the retention modules to the system board with the plastic rivets. The retention
modules are keyed to the processor slots to ensure correct orientation.
5.
Tighten all fasteners that secure the system board and retention modules to the chassis.
6.
Install the DIMMs and the processor modules to the system board.
7.
Install the expansion cards back into their original slots.
