3. Installing jumpers on the terminator power source jumper
block. To select the termination power source, install jumpers
for the appropriate case as follows:
•
To provide terminator power to the SCSI connector and the
drive terminator packs, install jumpers on pins 21 and 23 and
on pins 22 and 24 of J8. This is the default case.
•
To select the drive power connector as the termination
power source for the resistor packs, install a jumper on pins
23 and 24 of J8.
•
To select the SCSI connector as the termination power
source for the resistor packs, install a jumper on pins 21 and
23 of J8.
•
To provide terminator power to the SCSI connector from the
drive power connector only, install a jumper on pins 22 and
24 of J8.
Attaching cables
Figure 1 on page 4 shows connector and jumper block locations.
1. Turn off the system power and put on a grounded wrist
strap before proceeding.
2. Connecting a remote LED. (Optional) Connect a remote LED
to pins 9 and 10 of jumper block J8. Pin 9 is ground.
3. Attaching the power cable. Attach a system power cable to
the drive power connector J3.
4. Attaching the 50-pin SCSI interface cable. Attach one end
of the cable to the drive interface connector J1 and the other
end to the interface connector on the host system mother-
