The single ended drive drive is shipped with 3 terminator
resistor packs installed. The resistor packs are located
under the drive as shown in figure 2.5. When installing
multiple drives on the SCSI channel, the packs must be
removed from all but the last drive in the chain. The drives
can be ordered from the factory with the packs removed.
When re-installing the packs, ensure that they are properly
keyed into their connectors (see figure 2-5).
Refer to figure 2-5 and table 2-2. The power source for
the terminator resistors can be reconfigured with the
appropriate shorting jumpers (0
=
open, 1
=
shorted).
SCSI Connector
An unshielded 50-pin SCSI connector is located on the
rear of drive electronics/controller PCA (see figures 2-3
and 2-5). The physical construction and pin assignments
for this connector conform to the SCSI specification for
single-ended drives. The connector pin assignments are
listed in table 2-1.
