60 Replacing and Adding Internal Devices
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:
1 Turn off the system and disconnect the power cord and all external
peripheral devices.
2 Open the case. (See “Opening the case” on page 18 and “Preventing static
electricity discharge” on page 17.)
3 Remove all expansion cards from the system. (See “Replacing an
expansion card” on page 46.)
4 Remove the two screws that secure the riser card assembly to the chassis,
then lift the riser card assembly out of the chassis.
5 Disconnect 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.
