On "WC" model drives the SCSI ID can be and presum-
ably will be, set over the 80 pin interface by the host
computer. Unless directed to do so by the system
documentation, no jumpers should be installed for
address selection. On "WC" model drives, the host
system also has complete control over motor start
functions, so no Motor Start or Delayed Motor Start
Jumpers should be installed.
Hawk 1LP family "W" model drives have terminator
resistor packs that are permanently installed, but can
be enabled or disabled by jumper plug. See jumper in
Figure 3a. If you are installing a single drive, the
terminator resistor packs must remain enabled. If you
are installing multiple hard disc drives, disable the
termination resistor packs from all the drives but the
one connected to the end of the SCSI I/O cable.
