Apple WS 9650 manual Scsi ID #, Device

BasicsUltra Wide SCSI - 29

factory, as well as the PCI SCSI card itself, have already reserved certain SCSI ID numbers on the Ultra Wide SCSI-3 bus. Other ID numbers are available for assignment to SCSI devices that are added later, as shown below.

SCSI ID #	Device
0	Factory-installed hard drive(terminated)
1	Second factory-installed hard drive (optional)
2 - 6	Available
7	SCSI PCI card (terminated)
8 - 15	Available

IMPORTANT: The factory-installed internal hard drive and the SCSI card are both terminated. Other SCSI devices that you install and connect to the Ultra Wide SCSI-3 bus must not be terminated. If you connect a terminated device to the internal SCSI interface, you may severely damage the logic board.
