1. Enter the console mode.
The procedure for programming parameters for DSSI devices from console
mode requires that you issue commands to those devices at the console
prompt (>>>). You may enter these commands in either uppercase or
lowercase letters. Unless otherwise instructed, enter each command, then
press Return.
Enter console mode as follows:
a. Set the Break Enable/Disable switch on the system console module to
the enable position (up, position 1).
b. Set the Power switch for each unit (each system in a DSSI VAXcluster
configuration, and any expanders for expanded systems) to on (1).
Wait for the system to display the console prompt (
>>>
).
2. To display the DSSI devices on embedded DSSI buses, enter SHOW DSSI
at the console prompt. To display the DSSI devices on KFQSA-based DSSI
buses, enter SHOW UQSSP.
