Chapter 5 Troubleshooting

Symptom:

• The mouse does not work or is intermittent

The HP Netserver automatically detects a mouse when one is installed. If the mouse or other input device is

not working, perform the following:

1. Review the Troubleshooting Checklist before you continue.

2. Check that the mouse cable is properly and securely connected to the server.

3. If a keyboard/monitor switchbox is used with this Netserver, plug the mouse directly into the

keyboard port of the Netserver. Verify the problem.

4. Ensure mouse's port does not have a resource conflict. Use the Setup Utility (press [F2]).

5. Ensure correct mouse driver has been installed onto the boot drive. Refer to the mouse

installation manual or the operating system manual.

6. Replace the mouse with a known-good unit.

7. If the problem persists, replace the system board.

8. Once a suspect part has been found, verify that it is the problem by reinstalling the part and

duplicating the error.

Flexible Disk Drive Problems

Symptoms:

• There are lost clusters

• There are read/write errors

• The Netserver will not start from a diskette

If you cannot boot from, write to, or format the flexible disk, do the following:

1. Review the Troubleshooting Checklist and read about Boot Device Priority before you

continue.

2. Try booting from a known good flexible disk.

3. Check to see if boot from CD-ROM is enabled and if there is a bootable CD in the CD-ROM

drive.

4. Select the Setup Utility (press [F2] during the boot process) and check that the Netserver's

mass storage configuration is correct. If for some reason you cannot run the Setup, you can

clear CMOS and reconfigure the server.

Try to reboot.

5. If you cannot format or write to a flexible disk:

◊

◊◊

◊ Ensure diskette is not write protected.

◊

◊◊

◊ Ensure disk drive is properly configured with the Setup Utility. Make sure that "Start from

Flexible Disk" option is disabled.

6. Verify all internal drive cables are securely attached and functional. Inspect the cables and

reseat the connectors at both ends.
