    Hello Extreme Community,

    I am trying to find out how much power the:
    -ISW 4GBP,2GBT,2-SFP
    -ISW 8GBP,4-SFP
    (part no.16803 and 16804)
    Switches require to run without any PoE devices and what is the max power consumption total with all PoE+ ports outputting 30watts.

    Will the ISW 4GBP,2GBT,2-SFP be able to output 30w PoE+ on all 4 ports with a 240w PSU ?

    Hi Jake,

    The PoE budget according to the ISW data sheet is -
    • POE Budget 16801 and 16803 – 120 watts
    • POE Budget 16802 and 16804 – 240 watts

    And without PD loading, the consumption is 15 W.

    Thanks Sushruth,

    I have checked the data sheet. I am not clear what PD Loading means. I was hoping to find a total power usage of the switch when it is turned on running with all ports connected without PoE... is that what 'without PD loading' means ? (the switch only takes 15w to operate with all ports linked up and running at 1gbps ?)

    bump to get clarification on what 'PD loading' means in the Data Sheet.

    Hi Jake,

    Yes, you are right. Without PD loading, it is 15W. With full PD loading, it will be 15+240W = 255W.
