Troubleshooting
2. If a KVM switch box is used with this HP Server, remove the mouse and plug the mouse directly into the
mouse port on the HP Server..
3. Ensure that the mouse port does not have a resource conflict with another device. Use the system BIOS
Setup Utility (F2) to check.
4. Ensure that the correct mouse driver has been installed onto the boot drive. Refer to the mouse installation
manual or the operating system manual.
5. Replace the mouse with a known good mouse.
If the problem persists, the system board may need to be replaced. Contact the HP Customer Support Center for
further troubleshooting assistance before replacing any parts.
Floppy Disk Drive Problems
If the HP Server cannot boot from, write to, or format a flexible disk, do the following:
1. Try booting from a known good flexible disk.
2. If there is a bootable CD in the CD-ROM drive, remove it. By default, the CD-ROM drive is first in the boot
order, so if there is a CD-ROM disk in the drive, the HP Server will not boot to a bootable flexible disk.
3. Select the system BIOS Setup Utility (<F2> on POST when prompted) and verify the mass storage
configuration is correct.
4. Ensure the disk is not write-protected.
5. Ensure that the disk drive is trying to be accessed. Look for an activity light on the drive.
6. Try another flexible disk.
7. Boot to the HP Navigator CD and try creating a disk form the Diskette Library. This will eliminate the NOS
causing the problem since the Navigator is only using DOS.
Flexible Disk Drive Problems
1. Verify that the internal drive cables are securely attached and functional by inspecting the cables and
reseating the connections at both ends.
2. If the cables are securely attached and the drive still does not work, replace the cable with a known good
cable.
If the problem persists, call the HP Customer Support Center for further assistance before replacing any parts.
CD-ROM Drive Problems
The CD-ROM drawer will not open
If the CD-ROM drawer fails to open when you press the Eject Button or with software commands, do the
following:
1. Turn off all power to the HP Server tc4100.
NOTE
Make sure the mouse is plugged into the mouse port and not the keyboard port.
NOTE
If for some reason the system BIOS Setup Utility cannot be accessed, clear the CMOS.
See Clearing BIOS Configuration previously in this chapter.
