Planning and
Implementation for the 2600-
PWR Switches
■ When two switches are connected to the 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 7.5 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.
