If you cannot determine the problem by checking the specific area, perform each of the following actions. 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 17) exist in the rest of the server, particularly with the cables that connect to the system board. • Be sure no foreign material exists, such as screws, bits, or slot bracket blanks, that may be short circuiting components.
