On the internal/external bus, you can use SCSI ID numbers 0, 4, 5, 6. The
secondary hard disk (in the top bay of the internal disk drive bracket), the
optional built-in DAT drive (or any other drive in your server’s auxiliary bay),
and the built-in CD-ROM drive reserve SCSI IDs 1, 2, and 3, respectively, on
the internal/external bus. If you do not have a secondary hard disk in the
internal disk drive bracket, you can also use SCSI ID 1 for this bus; if you do
not have a DAT or other drive in the auxiliary bay, you can use SCSI ID 2 on
this bus.
3 Locate the ID number switch on the back of your SCSI device.
4 Push the ID switch repeatedly until the number you want appears.
On some SCSI devices, the ID number switch is inside a small hole. Insert a
straightened paper clip to push the switch.
Follow the instructions in the next section to install an additional hard disk in
the internal disk drive bracket. To replace or install a drive in the server’s
auxiliary bay, see “Installing a Drive in the Auxiliary Bay.” To connect
external devices to your server, see “Connecting an External SCSI Device.”
