c.Replace the remaining processor with a known functional processor. If the problem is resolved after you restart the server, a fault exists with one or more of the original processors. Install each processor and its associated PPM (if applicable) one by one, restarting each time, to find the faulty processor or processors. Be sure the processor configurations at each step are compatible with the server requirements.

System open circuits and short circuits

Action:

CAUTION: Do not operate the server for long periods with the access panel open or removed. Operating the server in this manner results in improper airflow and improper cooling that can lead to thermal damage.

1.Check the server LEDs to see if any statuses indicate the source of the problem. For LED information, refer to the server documentation.

2.Remove all power sources to the server.

3.Be sure no loose connections (on page 15) exist in the area.

4.Be sure each component in the area is working. Refer to the section for each component in this guide.

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 15) 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.

External device problems

Video problems

Screen is blank for more than 60 seconds after you power up the server

Action:

1.Be sure the monitor power cord is plugged into a working grounded (earthed) AC outlet.

2.Power up the monitor and be sure the monitor light is on, indicating that the monitor is receiving power.

3.Be sure the monitor is cabled to the intended server or KVM connection.

4.Be sure no loose connections (on page 15) exist.

•For rack-mounted servers, check the cables to the KVM switch and be sure the switch is correctly set for the server. You may need to connect the monitor directly to the server to be sure the KVM switch has not failed.

•For tower model servers, check the cable connection from the monitor to the server, and then from the server to the power outlet.

5.Press any key, or type the password, and wait a few moments for the screen to activate to be sure the energy saver feature is not in effect.

6.Be sure the video driver is current. Refer to the third-party video adapter documentation for driver requirements.
