    I have a 5400r with qty. 4 

    Power Supply Status:

    PS# Model Serial State AC/DC + V Wattage
    ---- --------- ------------ ----------------- -------------- ---------
    1 J9828A IN81G4D0YX Powered AC 120V/240V 700
    2 J9828A IN81G4D0Z7 Powered AC 120V/240V 700

    I don't think there are any commands that dictate behavior, they are always in a redundant mode. Look forward to an expert weighing in though.

    Hello,

     

    You should get an option to set the redundancy to full or N+1.

    n+1: One of the highest power supplies will be held
    inreserve. In the event of a simple power supply
    failure,no powered devices will be shut down.
    full: Half of the available power supplies will be held
    inreserve.

     

    Full will provide better redundancy as if even both active power supplies goes down ,other 2 can take over

     

    To select the configuration:

    #power-over-ethernet redundancy [full | N+1]
