Apple Workgroup Server 8150/110 - Manual (Page 51)

2 Choose a number between 0 and 6 that doesn’t duplicate the ID of any other SCSI device
connected to your server on the same SCSI bus.
Your server has two SCSI buses. One is the internal bus and the other is the
external bus. On the internal bus, you can use SCSI ID numbers 1 through 6.
(SCSI ID 0 is reserved for the internal hard disk.) On the external bus, you can
use SCSI ID numbers 1, 4, 5, 6. (The DAT drive and the CD-ROM drive
reserve SCSI IDs 2 and 3, respectively, on the external bus, even though they
are inside the server.)
See “SCSI Bus Specifications” in the Technical Information booklet for more
details on SCSI ID numbers.
3 Locate the ID number switch on the back of your SCSI device.
4 Push the ID switch repeatedly until the number you want appears.
On some SCSI devices, the ID number switch is inside a small hole. Insert a
straightened paper clip to push the switch.
Connecting a SCSI device
To connect a SCSI device to your server:
1 Make sure that the server and SCSI device are turned off.
WARNING Do not connect or disconnect any device while the device or
your server is turned on. Doing so could damage the device, your server,
or both.
