Before installing the SCSI hard disk drive,
you
need to check the
jumper settings on the drive. The jumpers determine the following
settings:
SCSI ID of the drive (J6)
n
Parity checking (J6)
n
Drive power-up (J6)
n
SCSI bus signals (J7)
n
Terminator power (J8).

J7
The jumper labeled J7 controls the type of bus signals used by the SCSI
adapter. Pins 3 and 4 must have a jumper installed and all other pins
must be off; this indicates that the SCSI interface is singled-ended. Do
not change this jumper setting.
Jumper J8 determines whether the hard disk drive or the SCSI interface
powers the terminators on the drive. The hard disk drive is shipped
with jumper J8 installed so that the hard disk drive automatically
provides power to the terminators. You should not remove this jumper.
