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.

Terminator resistor packs
Model ST12400W family drives have I/O line terminator
resistors 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 resistors must remain enabled. If you are
installing multiple hard disc drives, disable the termina-
tion resistors from all the drives but the one connected
to the end of the SCSI I/O cable.
