You can optionally configure your switch for N+N redundancy, in which N power supplies
can be removed or fail and the remaining N power supplies continue to supply power for
the switch without interruption. A common application for N+N redundancy is to have a
dual power feed for AC power supplies.
How many power supplies you require for N+N redundancy can depend on which Junos
OS Release your switch is running:
