7-26 Troubleshooting
The keyboard or mouse fails to operate:
Is the cable properly connected?
→ Make sure that the cable is connected to the correct connector on the rear of the
server.
Are the keyboard and mouse are compliant with NEC Express5800/ft series?
→ Operation of the server with unauthorized devices is not guaranteed.
Is BIOS configuration correct?
→ The keyboard and mouse may be disabled with the BIOS setup utility of the server.
Check the settings with the BIOS setup utility.
<Menu to check: [Advanced] → [Keyboard Features]>
Does the server have drivers installed?
→ Refer to the manual that comes with your OS to check that the keyboard and
mouse drivers are installed. (These drivers are installed along with the OS.) Some
OS's allow you to change the keyboard and mouse settings. Refer to manual that
comes with your OS to check that the keyboard and mouse settings are correct.
Are you using a PS2-USB conversion connector?
→ The PS2-USB conversion connector is not supported. Use the keyboard and
mouse that are specified by NEC.
Screen freezes, keyboard and mouse do not work:
→ If the amount of memory is large, it takes time to copy the memory in dual mode
and the system stops working during the copying. It is not system trouble.
Message "New Hardware Found" appears:
→ Such a message may appear at the system startup or when a PCI module is
replaced and incorporated into the system. This is due to the server's operating
specifications and does not pose any problem.
Fail to access (read or write) to the floppy disk:
Does the floppy disk drive contain a floppy disk?
→ Insert a floppy disk into the floppy disk drive until it clicks.
Is the floppy disk write-protected?
→ Place the write-protect switch on the floppy disk to the "Write-enabled" position.
Is the floppy disk formatted?
→ Use a formatted floppy disk or format the floppy disk in the floppy disk drive.
Refer to the manual that comes with the OS for formatting a floppy disk.
