The following table shows examples of the maximum number of PoE ports that can be supported by the four 
Power over Ethernet capable Switch 3500 series models. One column shows the maximum number of PoE ports 
at full power (Class 0—5.4 watts) and the other column shows the maximum number of PoE ports at typical 
phone power (8 watts).
For environments needing more PoE power, the HP ProCurve 620 Redundant/External Power Supply can be 
used. It doubles the available PoE power from 398 W to 796 W for up to two Power over Ethernet capable 
Switch 3500 series. The HP ProCurve 620 RPS/EPS also provides redundant system power for up to two 3500 
series switches.
