You can 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 to the
switch without interruption.
Table 46 on page 168 lists the N+N power calculation for 24-port EX4300 switches that
use 350 W, 715 W, and 1100 W power supplies.
