Location of System Board Assembly
WARNING Always disconnect the power cords before removing the covers, to avoid exposure
to high energy levels that may cause burns when parts are short-circuited by metal
objects such as tools or jewelry. Disconnect any telephone cables to avoid exposure
to shock hazard from telephone ringing voltages.
5. Unlatch the blue retaining latches to release the board.
