With an HP 600 RPS/EPS Powering Two Switches

■ 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.
