Drive configuration
Each disc drive has one or more option select header
connectors on the back, side or 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. See
notes following Figure 3b.
Hawk 1LP family N/ND models (50 pin SCSI I/O)
On  Model N/ND drives either J6 (on the front of the
drive) or J5 (on the side behind the DC Power connec-
tor) 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 covered by
this manual. See notes following Figures 3a  and 3b
where explanations are given about the purpose of
each jumper and specify the standard factory (called
"default") 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.
