DC Power connection
Hawk 1LP family "W/WD" model drives receive DC
power through a 4 pin connector mounted on the PCB
in line with the SCSI I/O connector. See figure below.
Figure 1.
DC power connection, 68 pin SCSI I/O
connector
Hawk 1LP "WC" model drives receive power from the
host computer through the 80 pin combined SCSI I/O
and power connector. No separate DC power connec-
tor is provided on the drive (See Figure 2b).
SCSI address selection
On "W" and "WD" model drives, make sure that the
SCSI bus address jumper(s) are properly set for the
bus address assigned to the drive. See figures 3a and
3b showing the bus address select header and the
jumper configurations that select addresses 0 through
15. Typically the primary boot device is set to ID 0, and
the subsequent SCSI drives are jumpered in ascending
