3 High/Low SCSI IDs

the cage will be the lower IDs or the higher
IDs.

tables below for settings.
Note: Setting this switch may cause time-out
problems with your NOS due to delayed
start of devices with high SCSI ID numbers.
On Assigns high SCSI IDs to the cage.
Off Assigns low SCSI IDs to the cage.
4 SCSI ID Zero
Determines SCSI ID of middle shelf in cage
(see tables below for settings).

sequence (ID 2 or ID 5).
5 Remote Start
