Hawk 2  (Wide bus) Family Install Guide, Rev. C

Notes for Figure 3a, 3b and 3c:

[1] Notes explaining the functions of the various jumpers

on jumper header connectors J2, J1-auxiliary and J6
are given below in left to right order of jumper position.
The term "default" means as standard OEM units are
configured when shipped from factory. "Off" means no
jumper is installed; "On" means a jumper is installed. Off
or On underlined is factory default condition.

[2] The PCB on "WC" models does not have connector J1-

auxiliary, but has a single 80 pin combined SCSI I/O and
DC power connector instead of the 68 pin SCSI I/O and
4 pin DC power connectors. Included among the 80 pins
are the SCSI ID, Motor Start and Delayed Motor Start
select functions, and the synchronous spindle master
sync signal and the remote LED signals. Do not use J2
and J6 for these five functions if the host uses the ones
included in the 80 pin connector.

[3] Drive ID may be established by installing jumper plugs

in one of the patterns shown in Figures 3a, 3b and 3c,
or by plugging onto J6 or J1-auxiliary a cable that leads
to an external ID selection circuit. Both jumper plugs
and an external ID selection source should not be used.
See [4] for other functions of these two headers that are
time-shared with the drive ID function.
