Troubleshooting Checklist

1. Verify the error. Be sure it is not an erroneous error message. Is the error repeatable? Is
the error message seen affecting the HP server's operation or performance?
2. Always change only one component at a time.
3. Always check the most recently added items added, both hardware and software. Remove
any third-party components.
4. Be sure the HP server BIOS is updated to the latest version posted to HP's external
website. Flashing/updating the system BIOS and clearing CMOS will resolve many
different issues.
5. Be sure the firmware for the hard drives are kept current. Download and run the Hard
Disk Drive Firmware Utility to verify if hard drive firmwares need to be updated. This
utility is available from HP's external website.
6. Be sure all firmware/BIOS revisions on any controllers are kept current.
7. Use only HP-provided drivers for any HP devices used in the HP server. This includes
using HP drivers for the initial installation of any NOS (Network Operating System) that
is supported on the specific HP server.
8. Check all cable and power connections, including those in the rack. If the HP server is
not powering on, unplug the AC power cords and wait 20 seconds then plug the AC
power cords in again and restart the HP server. Check for normal operation.
9. Verify that all cables and boards are securely plugged into their appropriate connectors
and slots.
If the problem still persists:
1. Simplify the HP server's configuration. The minimum required:
— Monitor
— Keyboard
— Mouse
— 1 hard drive (may need to disconnect for hardware troubleshooting)
— CD-ROM and Flexible disk drive (may need to disconnect for hardware
2. Reconnect the power cords and power on the HP server. If operational, power back down
and reinstall one component at a time and power on the HP server after the installation of
each component to try and determine which component is causing the problem.
If the problem persists, call the HP Customer Support Center for further troubleshooting
assistance.
