Hawk 1LP (Wide) Installation Guide, Rev. B 23
Hawk 1LP family "WC" model 80 pin SCSI I/O drives
On Hawk 1LP family "WC" model drives there is no J1-
auxiliary connector. J6 can be used to set drive ID, but
the host probably does it over the 80 pin interface. J6
can also be used to drive LED indicators and the
synchronized spindle reference signal. The alternate
use of J6 is described in the notes following Figure 3c.
