Jumper 5

the i-Drive. This is normally unnecessary because terminator power is normally sup-
plied by the SCSI controller.

Configuring the SCSI address
Each of the maximum of 8 devices connected to the 8-Bit SCSI Bus must have a
unique SCSI address, also called SCSI ID. The SCSI address of the i-Drive is configured
with
Jumpers 1 to 3
on jumper block S1 as shown in the table:

To avoid conflicts with other SCSI devices, make sure that each device has its own
unique SCSI ID.

Note:
the SCSI controller itself is also a SCSI device and usually has the SCSI
ID 7. The internal hard disk usually has the SCSI ID 0.
