Chapter 6 Troubleshooting
Troubleshooting Sequence
To troubleshoot an installation problem, do the following:
• First make sure that the system is configured properly. Most system
problems are the result of incorrect system and SCSI subsystem
con^gurations.
• If it is a network-related error, determine if the HP NetServer has enough
memory and hard disk drive capacity. Consult your network operating
system manual.
• Verify that all cables and boards are securely plugged into their appropriate
connectors or slots.
• Remove all added options, and always change one thing, and only one
thing, at a time.
• Unplug the power cord, wait 20 seconds, plug the power cord in again, and
restart the system.
NOTE Ifthe HP NetServer has a large amount of memory installed, it
may take one minute for the first screen to display.
If you suspect a hardware error, follow these steps:
1. Log users off the LAN and power down the HP NetServer. Remove the
^ont bezel, top cover, and side cover.
2. Simplify the HP NetServer con^guration to the minimum required: a
monitor, one ^exible 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 system a^er each installation.
3. Replace all covers, and reconnect the power cord and other cables.
4. Restart the system. If the system does not function, refer to one of the
following sections, depending upon whether an error message is displayed:
0 "Error Message Is Displayed"
0 "No Error Message Displayed"
5. If the system still will not restart, clear the system con^guration memory
and restart the system, as described in "Clearing the System
Con^guration."
