refer to the server documentation.
2. Remove all power sources to the server.
3. Be sure no loose connections (on page 22 ) exist in the area.

Restart the server after each action to see if the problem has been corrected.
• Reseat all I/O expansion boards.
• Be sure no loose connections (on page 22 ) exist in the rest of the server, particularly with the cables
that connect to the system board.
