xx = chain position = 01 to 12, or BU. Where BUselects the
converter as the backup.
yy = chain length for xx = BU (i.e. Backup Converter) 01 to 12.
yy = P1 or P2, single or dual polarity
Example 1: The following command assigns the converter chain position "1".
>DEV/ICT_01'cr''lf']
Example 2:
The following command assigns the receiving converter as the backup
converter in a 1:8 system.
>DEV/ICT_BU_08'cr''lf']
It should be reiterated that only the converter physically located at the top of a redundant
rack should be assigned as the Backup unit. Likewise, assignment of chain positions in a
redundant rack should be made according to the physical allocation of each converter in
the rack (i.e. The top converter should be the Backup, the second converter should be
assigned chain position 1, the third converter position 2, etc.).

This command provides for automatic switching by the backup Converter if both units
are in the Redundancy Mode. This command is only accepted by the backup Converter.
If a chain converter is set in Manual Mode, the backup Converter will log the occurrence
and not act upon further information from the converter until put into Automatic Mode.
The default is off.
