10. Remove or set disk drive termination jumpers to the disabled position
(if needed). Refer to your system documentation furnished with your
disk drives to determine if your termination jumpers need to be
adjusted.
11. Set the SCSI ID on the disk drives; ID 7 is reserved for the controller.
☛
Note
Each drive must have a unique ID chosen from
0 through 6 or 8 through 15. Be careful not to
duplicate a drive address on the same channel.
Remember: ID 7 is reserved for the controller;
therefore, it cannot be used as a disk drive ID.
ID’s from 0 through 6 are usually for Narrow,
8-bit devices. However, the full range of SCSI ID
addresses, 0 through 6 and 8 through 15 can be
used for Wide, 16-bit devices.
See your device documentation for instructions on
how to set your particular disk drive’s SCSI address.
