3-1 Troubleshooting Procedures
Use the following procedures to troubleshoot your system. If you have followed all
of the procedures below and still need assistance, refer to the ‘Technical Support
Procedures’ and/or ‘Returning Merchandise for Service’ section(s) in this chapter.
Always disconnect the AC power cord before adding, changing or installing any
hardware components.
Before Power On
1. Check that the onboard Power LED is lit (DP1 on the serverboard).
2. Make sure that the 8-pin processor power connector at JPW2 is connected to
your power supply.
3. Make sure that no short circuits exist between the serverboard and chassis.
4. Disconnect all ribbon/wire cables from the serverboard, including those for the
keyboard and mouse.
5. Remove all add-on cards.
6. Install a CPU and heatsink (making sure it is fully seated) and connect the chas-
sis speaker and the power LED to the serverboard. Check all jumper settings as
well.
7. Use the correct type of onboard CMOS battery as recommended by the manufac-
turer. To avoid possible explosion, do not install the CMOS battery upside down.
No Power
1. Make sure that no short circuits exist between the serverboard and the chas-
sis.
2. Verify that all jumpers are set to their default positions.
3. Check that the 115V/230V switch on the power supply is properly set.
4. Turn the power switch on and off to test the system.
5. The battery on your serverboard may be old. Check to verify that it still supplies
~3VDC. If it does not, replace it with a new one.
No Video
1. If the power is on but you have no video, remove all the add-on cards and
cables.
2. Use the speaker to determine if any beep codes exist. Refer to Appendix A for
details on beep codes.
