22 Elite 9 Installation Guide, Rev. B
To terminate ST410800N and ST410800W drives, en-
able the permanently mounted IC terminators by install-
ing a jumper on J4A pins 19 and 20 as shown in Figure 4.
If you install one of these models and it is not on the end
of the SCSI bus, remove internal termination from the
drive by removing the Enable Drive Terminator jumper
(see Figure 4). This disables the permanently mounted
IC terminators.
Note. This jumper applies only to N- and W-type models.
