Figure 3-2. Example of an HP 600 RPS/EPS Powering Two 2626_PWR Switches
■ When two switches are connected to the HP 600 RPS/EPS ports, the PoE
power available to each switch is a maximum of 204 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 is available as long as the total power required remains
below 204 W.
