When two switches are connected to the RPS 600 RPS/EPS ports, the PoE power available to each switch is a maximum of 184 W. If all of your PDs consume on average less than 7.6 W each (allowing for any line loss) then all 24 ports will receive redundant power should a switch’s internal PoE power supply fail.

Redundant power as long as the total power required remains below 184 W.
