| Description | The unit number associated with this unit.
The unit number can be manually assigned to stack members.
Note that the unit number assignment is based on
the following factors:
- if the unit number is requested here, but another unit
already uses that number, the unit changes its configured
unit number to the lowest unassigned unit number.
- if the unit number is 0, i.e. unassigned, then the unit sets
its configured unit number to the lowest unassigned unit number.
- if the unit number is configured and no other device uses
the unit number, then the unit starts using the configured
unit number.
- if a unit detects that the maximum number of units already
exist, the unit sets its unit number to 0, i.e. unassigned,
and stays in the Initialization state.
- The max number of stackable units allowed on this chassis
is found from the object chNumMaxStackableUnits. |
