Remote Unit ID Selection:
Pins 1-8 of this connector are provided
for remote unit SCSI ID selection through the computer system. Remote
ID selection requires that the unit ID switch located on the inside of the
receiving frame be set to “0” (onboard ID selection is set with a switch
located on the inside of the receiving frame as shown in Figure 4).
Remote Activity LED:
Pins 9 & 10 provide power to a remote LED
device activity indicator.
Enable Termination Power Connector (W2):
A jumper is installed
at the factory and enables termination power to/from the SCSI bus.
NOTE:
Do NOT remove this jumper!

Typical 2MM Drive ID Pin Confi guration
Figure 3 illustrates a typical SCSI ID select connection to a drive with
2mm ID select pins. The wires on the wire harness connect to the
positive pin (or signal pins) on the disk drive. In some cases, the drive
manufacturer will label the signal pins as Pin 1, 3, 5, 7, (instead of 0,
1, 2, 3 as shown in fi gure below). Also, in some cases, the even-num-
bered Pins 2, 4, 6 are used for Ground.
Attach the ID select cable to the drive using the 2mm connectors. Align
the “ID0” pin with the black wire. Attach the 1.25mm connector on the
other end of the ID select cable to the 1.25mm connector (J3B) provided
on the signal distribution board, located inside the carrier. Refer to the
manufacturer’s documentation to disable termination on the drive.
NOTES:
For SCSI Ultra320 operation, the Ultra320 DE100 requires Ultra320
drives, Ultra320 HBA, and Ultra320-compliant cabling (internal and external).
Ultra320 DE100 can support Ultra320 implementations with a maximum of fi fteen
(15) Ultra320 drives (Ultra320 repeater may be required).
Ultra320 DE100 receiving frames are indicated by their BLUE LED, while the
Ultra320 DE100 carriers are indicated by the Ultra320 logo.
