Selecting the SCSI ID Number
The SCSI ID is an address number (0-7 for 8-bit protocol and 0-15 for 16-bit protocol) that is
assigned to each SCSI device. Each device in the chain must have a unique SCSI ID number.
SCSI ID 7 is usually reserved for the host controller. If the computer system is already equipped
with internal or external SCSI storage devices, some ID numbers will already be reserved. For
instance, if the computer system came with an internal SCSI hard drive, it may be designated
as SCSI device 0 (refer to the computer system documentation for additional information).
Four (4) SCSI ID selection switches are located on the front panel of the DS351 enclosure
(Figures 3 & 13). These rotating switches can be adjusted with the provided alignment tool.
Carefully select the appropriate SCSI ID number(s) for the installed device(s). Note that some
switch settings may be invalid for your interface type. Selecting an invalid ID number, or
selecting the same number on different devices may cause unpredictable results and the
computer system may not recognize the installed device(s). If the computer system can not
recognize the boot disk, the computer system may fail to properly start-up.
