N+N Redundancy Conguraon of AC Power Supplies
You can congure your switch for N + N redundancy, in which N power supplies can be removed or fail
and the remaining N power supplies connue to supply power to the switch without interrupon.
Table 36 on page 100 lists the N + N power calculaon for 24-port EX4300 switches that use 350 W,
715 W, and 1100 W power supplies.
