N drives
Terminating the drive
“N” model drives are terminated with permanently mounted IC
active terminators. If you install one of these drives and it is not
on the end of the SCSI bus, disable the terminators by removing
the jumper “TE” from pins 15 and 16 of connector J2 (see Fig-
ure 8). If you install the drive on the end of the SCSI bus, enable
termination by installing a jumper on pins 15 and 16 of connector
J2.
