top" style="font: inherit;">The cable gets tested with whatever is on the
cable.  
The EUT then is to meet the standard.
And if you also bundle the PoE supply with your EUT (not likely but possible)
then the AC mains to that device would also suffer the same test.
And when you include Safety considerations it gets more complicated.

And given the you have video and digital and your company, vicon-security, the
EUT may not actually be ITE, but would instead need to meet EN 50130-4

        Hello all,
        
        I have an EUT that has the following data inputs
        
        1) Video Data Coax Cables (BNC) INPUT
        
        2) IP CABLE INPUT  THAT COULD CONTAIN BOTH DIGITAL DATA AND POE OR
        SIMPLY DIGITAL DATA
        
        3) 24vac INPUT
        
        
        I can config the EUT TO accept one of two (2) setup options
        
        A) 24vac with separate IP Cable CONTAINING DATA ONLY
        
        2) POE (no 24vac connected) via the IP Cable that is also carrying
        digital .
        
        
        My setup is using an EFT Tester that goes out to a Capacitive Clamp TO
        COUPLE THE SPIKES ONTO THE DATA LINES
        
        Setup A is not the problem, it is a simple conventional setup where the
        data IP cable alone is receiving the 2kv spikes @ 5KHz rep rate alone. 
        Once that test is completed the power supply will then receive 2kv
        spikes @ 5KHz rep rate spikes on the Line, Neutral,Gnd (with various
        combinations.)
        ************************************************************************
        *******************************
        
        Setup B is my conundrum, if I am using ONLY POE as my supply to the EUT
        the data line is (as you know) bundled into the IP Cable along with the
        POE.
        
        If I use the POE along there are spikes going straight into the input of
        the supply of the EUT . 
        
        The question is given the standard .. is this a valid configuration to
        test the EUT ?
        (BTW the EUT is classified as ITE )
        
        Thanking you in advance for your input,
        
        Best Regards,
        Reg Henry
