On the internal/external bus, you can use SCSI IDnumbers 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 SCSIID 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.
3Locate the ID number switch on the back of your SCSI device.
4Push the ID switch repeatedly until the number you want appears.
On some SCSI devices, the IDnumb er switch is inside a small hole. Insert a
straightened paper clip to push the switch.
Follow the i nstruct ions 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.”
