156 Chapter 14—SCSI & External Disk Drives
D24—Owner’s Manual
Connecting Disk Drives
The D24’s SCSI port is a 50-pin, half-pitch SCSI
connector, which accepts 50-pin, half-pitch,
pin-type SCSI plugs.
For reliable operation, use only good-quality SCSI
cables.
The total length of the SCSI bus must not exceed six meters (20 feet). Note that this is
the total length of the bus from the D24 to the last device, not the length of the cables
between individual devices.
In the following example, an external SCSI disk drive is connected to the D24.
Assigning SCSI IDs
Each device on the SCSI bus must be assigned an exclusive identity number called a
SCSI ID. There are eight SCSI IDs in all, however, 7 is reserved for use by personal com-
puters, 6 is used internally by the D24, and 2 is the default setting of the internal MO
disk drive. This leaves SCSI IDs 0, 1, 3, 4, and 5 available for use with external disk
drives.
The following table lists SCSI ID availability.
O = Available X = Unavailable
If two or more devices on the SCSI bus are assigned the same SCSI ID, the system will
not function properly and may hang. If the D24 displays a SCSI ID error message, turn
off all connected devices, and recheck the SCSI ID settings.
For information on setting the SCSI ID on your external SCSI disk drives, refer to the
relevant owner’s manuals.
