connector. You must install a 16-bit terminator on the
corresponding OUT connector. For more information on
terminators, read
“SCSI Terminators” (next section).
Note
If you attach the command module to an 8-bit bus, it will confine the
command module’s performance to 8-bit limits.
SCSI Terminators
If you install the command module where one
or both controllers are the last devices on a SCSI bus, you must
terminate the bus. To do this, you must put a 16-bit, differential
terminator on each SCSI-OUT connector on the command module's
back panel. For details on installing the command module, refer to
the instructions in Chapter 1.
SCSI Host ID Pins
If the command module is installed on a SCSI bus, the controllers
must have unique SCSI host ID numbers, which are set through ID
pins on the back of the unit (
Figure 34 on page 59 ). The factory
default settings for the controllers are SCSI ID 5 (Controller A) and
SCSI ID 4 (Controller B).
