Internal/External (INT/EXT) Jumper J8

When this jumper is in the “INT” position—jumper on pins 1 and 2 default setting—the backplane assumes it is operating in an “internal” peripheral bay in the chassis.

When this jumper is in the “EXT” position—jumper on pins 2 and 3—the backplane assumes it is operating in an “external” peripheral bay in a peripheral expansion chassis. This option is not available.

SCSI ID Configuration Options

The SCSI chip on the hot-docking backplane uses the SAF-TE protocol to communicate with the system board. This chip uses SCSI ID 6; therefore, other SCSI devices cannot use this address.
