Troubleshooting Checklist
To troubleshoot an installation problem, do the following:
•
First, ensure the NetServer is configured properly.
Most NetServer problems are the result of incorrect BIOS and SCSI configurations.
•
If it is a network-related error, determine if the NetServer has enough memory and hard disk
drive capacity.
Consult your network operating system manual and its requirements.
•
Verify all cables and boards are securely plugged into the appropriate connectors or slots.
•
Remove all options added since the NetServer was received and then add one option, and only
one option, at a time.
NOTE If the NetServer has a large amount of memory installed, it may take 30 seconds for
the first screen to display.
If it is a hardware error, follow these steps:
1. Log users off the LAN and power down the NetServer.
2. Remove the NetServer's cover.
WARNING Before removing the cover, always unplug telephone cables and disconnect the
power cord. Unplug telephone cables to avoid exposure to shock hazard from
telephone ringing voltages. Disconnect the power cord to avoid exposure to high
energy levels that may cause burns when parts are
short-circuited by metal objects such as tools or jewelry.
3. Simplify the HP NetServer configuration to the minimum required:
A monitor, one flexible disk drive, one CD-ROM drive, one hard disk drive, keyboard, mouse,
and NIC. Remove all third-party options, and reinstall one at a time, checking the NetServer
after each installation.
4. Boot the NetServer.
◊
If the NetServer does not function, consult the troubleshooting steps in the section
"Hardware Problems."
◊
If you get an error message, see the section "Error Messages" below.
5. If the NetServer still will not boot, clear the CMOS memory and reboot. See "Clearing the
CMOS Configuration".
If the NetServer Does Not Power On
Follow these steps if the power/activity light does not light green after you press the power-on button:
1. Remove the AC power cord, wait 15 seconds, reconnect the power cord, and try again.
2. Verify all cables and power cords are firmly plugged into the respective receptacles.
