Troubleshooting Checklist
These instructions do not generally cover third-party components or devices. Refer to the documentation that
comes with the third-party device for diagnostic and troubleshooting information. When replacing the
processor or system board, make sure all previously installed components are removed from the original
processor or system board and are installed on the replacement board.
NOTE This information assumes that the customer is booting MS-DOS (note that
DiagTools is based on MS-DOS). If the customer is not using MS-DOS, reboot the
system with a DOS diskette.
When troubleshooting:
• First make sure that the system is configured properly. Most system problems are the result of
incorrect system and SCSI subsystem configurations.
• If it is a network-related error, determine if the user has enough memory and hard disk drive
capacity. Run the diagnostics for the network interface cards. Consult with the network
operating system manual.
• If it is a hardware error, follow the instructions to log users off the LAN and power down the
server. Boot the Power-on Self-Tests (POSTs). If you get an error, look up Error Messages
for further instructions. If the POSTs pass, you can run the HP DiagTools. Besides the POSTs
and HP NetServer DiagTools disk, the standard set of tools recommended for troubleshooting
are:
◊

◊ HP NetServer Assistant. HP NetServer Assistant (NSA) is a customizable software toolset
that helps monitor and manage servers over the network from an HP OpenView console.
The NSA software has a server part and a management console, or client, part.

◊ TopTools. HP TopTools provides a set of web-based management tools you can use to
maintain and control your HP NetServers running Microsoft Windows NT, Novell
NetWare/IntranetWare, or SCO UNIX.
• Always change one component—and only one component—at a time.
• Verify the error.
Check for any general problems:
1. Check that all cables and power cords are firmly plugged into the correct receptacles.
2. Check that all equipment connected to the HP NetServer is turned on.
3. Verify that power is available and is within specification.
4. Check that the HP NetServer is configured correctly in the Setup Utility by pressing [F2] during
the boot process or by booting the HP NetServer Navigator CD-ROM.
5. If the server still doesn't work, turn off the monitor, the server, and all external devices. Note the
location of all power cords and other cables before unplugging them. Then:
a. Remove the cover.
b. Check that all accessory boards are firmly seated in their slots.
