SCSI Hard Disk Drive Configuration
You need an optional SCSI controller and internal SCSI cable to install a SCSI hard
disk drive or file device.
Set SCSI IDs as shown in the figure below. Set the terminating resistor (Enabled/
Disabled) for the last-connected device in the SCSI chain. Set "Disabled" for all the
middle devices. A terminating connector may be installed depending on the internal
SCSI cable. If the SCSI cable ends with a terminating resistor, set "Disabled" for all the
terminating resistors of connected devices. For the settings, refer to the manual which
is included in the NEC Express Builder’s Online documentation section.
A file device needs settings such as a SCSI transfer rate. For the transfer rate, see the
manual provided with the file device. Use the BIOS utility of the SCSI controller to
make the settings. For details, see the manual provided with the SCSI controller.
