Replacing the system board
The system board integrates the other elements of the system, such as the processor, memory, storage, networking, and communications.
To replace the system board:
1Turn off the system and disconnect the power cord and all external peripheral devices.
2Open the case. (See “Opening the case” on page 18 and “Preventing static electricity discharge” on page 17.)
3Remove all expansion cards from the system. (See “Replacing an expansion card” on page 46.)
4Remove the two screws that secure the riser card assembly to the chassis, then lift the riser card assembly out of the chassis.
5Disconnect all cables from the system board. Note the location and orientation of each cable before you remove it so you can replace it when you have installed the new system board.
