System4 Components

The system board

The system board is the heart of the computer, which 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.

Removing the system board

The system board is mounted on stand-off retention hooks on the right side of the chassis. The board is secured by two screws, one located on the back-right of the chassis, and one located inside the case.

Important All references to front, rear, left or right on the computer are based on the computer being in a normal, upright position, as viewed from the front.

To remove the system board:

1Turn off the system and disconnect the power cord, modem cord (if installed), and all external peripheral devices.

2Open the case by following the instructions on page 17. (See “Preventing static electricity” on page 15.)

3Place the chassis gently on its right side.
