Installing the System Board

CAUTION: Only trained service technicians are authorized to remove the system cover and access any of the components inside the system. See your Product Information Guide for complete information about safety precautions, working inside the computer, and protecting against electrostatic discharge.

1Unpack the new system board.

2Install the system board.

a Hold the system board by its front edge and the memory module socket ejectors.

b Carefully lower the system board into the chassis with the DIMM-socket side of the board tilted down slightly to allow room for the board to clear the chassis wall slides. Ensure that the I/O connectors on the back edge of the board fit underneath the ledge on the inside of the chassis back panel.

When the board is properly positioned, the tabs on the chassis will fit through the corresponding slots in the system board.

c Slide the system board tray toward the back of the chassis until the retention pin snaps into place.
