Drive configuration
Each disc drive has option select header connectors on
the sides and front where jumper plugs are installed to
select the way that the drive is to be configured or to
select its ID on the I/O bus.
SCSI I/O drives
On SCSI I/O model "N/ND" drives either J6 (on the front
of the drive) or J5 (on the side behind the SCSI I/O
connector) may be used to set the drive ID. To avoid
possible incorrect ID setting, do not use both J5 and J6
for ID selection. The following figures show where
these headers are located on the different drives cov-
ered by this manual. There are notes following where
explanations are given about the purpose of each
jumper and specify the standard factory (called "de-
fault") settings of these jumpers (i.e., settings used for
most common single drive application). Changes to
these settings should be made only if it is known that the
system requires a different configuration.
SCSI model "NC" drives do not have J5 for ID selection.
The ID signals come in the 80 pin I/O connector, so
drive ID selection can be made over the interface from
the host. J6 can be used but probably is not to be used.
