>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.).
