Figure 16. Terminating the drive.
Terminating the drive
To terminate the ST15150W drive, enable the perma-
nently mounted IC active terminators by installing an
Enable Drive Terminator jumper on J4 pins 11 and 12 as
shown in Figure 16. If you install one of these models
and it is not on the end of the SCSI bus, remove the
jumper to disable the permanently mounted IC termina-
tors and thereby remove internal termination from the
drive.
The ST15150WD drive does not have internal termina-
tors or any way of adding internal termination. You must
provide external active termination (ANSI SCSI-2 Alter-
native 2) to the drive when termination is required.
