6.3 SCSI IDs
To check the IDs of SCSI devices connected to a TURBOchannel option
module, follow the same steps as for checking devices connected to the SCSI
connector on the system unit, except type cnfg 0 or cnfg 1 at the console
prompt, depending on the TURBOchannel slot to which your external drive is
connected.

6.3.3 Changing SCSI IDs

All SCSI storage devices have a set of small switches or a row of small pins
and jumpers that are used to set the SCSI ID. You change the ID by flipping
these switches or moving jumper blocks into different positions on the pins.
The switches on the various kinds of storage devices are all slightly different.
For instructions on identifying or changing the SCSI IDs on the RZ23L, RZ24,
and RZ25 hard disk drives, see Section 9.5.1. For information about other SCSI
devices, refer to the guide that came with the expansion box that contains the
device, and to the documentation that came with the device itself.

6.4 To Connect an Expansion Box to the System Unit

If you're connecting a TURBOchannel extender box (TCE) to the SCSI
connector, see the guide that comes with the TCE.
To connect other expansion boxes to the SCSI connector, follow these steps:
1. Turn off the system unit.
2. Find the system-unit-to-expansion-box cable, which has a small metal
connector on one end. Hold this connector so that its widest part is on top.
3. Pinch together the sides of the cable connector to open it. Push the cable
connector all the way into the SCSI connector on the system unit.
