Replacing the system board
The system board integrates the other elements of the system, such as the processor, memory, storage, networking, and communications, and lets them operate in a coordinated and useful way.

To replace the system board:
1Turn off the system and disconnect the power cord, modem cord (if installed), and all external peripheral devices.
2Observe all safety and static electricity precautions. (See “Preventing static electricity discharge” on page 22.)
3Remove the bezel. (See “Removing the bezel” on page 25.)
4Remove the left side cover panel. (See “Removing the side cover panel” on page 26.)
5Place the chassis gently on its right side.
6Remove all expansion cards from the system. (See “Replacing an expansion card” on page 63.)
7Remove the back panel fan (see “Replacing the back panel and drive cage fans” on page 73.)
8Disconnect all cables from the system board, including the power cables from the power supply, noting their locations and orientations (you will reconnect these cables after you install the new system board).
