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.
