Resetting the SCSI ID on the Second RRD40 Expansion Box
If you add two RRD40 expansion boxes to your system, you must reset the
switches on the second RRD40 to an open ID—one that is not currently
being used. In the following example, ID 0 is an open ID. You could select
ID 0 by setting switches 1, 2, and 3 down (Figure 4–4).
To determine available IDs on the SCSI-B bus on your InfoServer 100
system, enter TEST 50 at the console prompt
(>>>)
, then press
Return
.
Your system configuration appears on the screen. FFFFFF05 indicates an
open SCSI ID. Look for a display similar to the following:
SCSI-B
1C1C.0001
V1.3
FFFFFF05 05000001 05000001 05000001 05000001 05000001 FFFFFF03 FFFFFF05
