Chapter 5 SCSI Backplane and Drives: Hot-swapping and Configuring
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.
