Printer Problems; The Keyboard Does Not Work - HP ProLiant ML150 Operation Manual

Troubleshooting

Printer Problems

If the printer does not work, do the following:
1. Verify that the AC power cord is plugged into the power source and the printer.
2. Be sure the printer power switch is ON and the AC outlet is working.
3. If the printer is plugged into a multiple-outlet box, be sure the switch on the outlet box is
turned on and the circuit breaker (if applicable) is not tripped.
4. Be sure the printer is online and available for printing.
5. Verify the correct cables are being used and that the cables are connected properly. Be
sure the cable pins are not bent.
6. Try a known good cable.
7. If the printer's parallel date cable is plugged into the HP server after the server is on,
reboot the HP server.
8. Examine the printer for a paper jam.
9. Run the printer self-test. Refer to the printer's manual for instructions.
10. Be sure the correct port setting when configuring the printer.
11. Run the system BIOS Setup Utility (pressing the Delete key on POST when prompted) to
verify the I/O port status. Be sure it is not disabled.
12. Test another peripheral from the HP server's parallel port to ensure functionality.
If the printer still does not work, contact the HP Customer Support Center for further
assistance.

The Keyboard Does Not Work

NOTE: Use only an HP-Approved Keyboard as others may not work correctly.
If the keyboard does not work or a character is not displayed when a key is pressed:
1. Be sure that the keyboard is not locked, if the HP server has this feature.
2. Be sure that the keyboard cable connections at the rear of the HP server and at the back of
the keyboard are secure.
NOTE: Be sure the keyboard is plugged into the keyboard port and not into the mouse port in the back
of the server.
3. If the KVM switchbox is used with this HP server, remove the keyboard and plug the
keyboard directly into the keyboard port of the HP server.
