This week i saw a POE situation that i don't know if is normal or is a bug.
I have many WS-12-250-DC switches working with a port with POE 48VH. Also i have some WS-12-250-DC working with two ports working at 48VH POE. All switches are working with 24 Volts DC.
This week i configured the same whit but now power is at 55 Volts DC.
Now in this switch i only can select one port at 48HV the other Port POE option are in blank (2-4) Rest of ports only can select 24 or 48 at 0.75
I don't understand why working at 24 volts i can use two ports at 48VH but working at 55 only cant use one port at 48VH
Thanks.
