Hi,

How did you make that measurement?

If we assume the AX23's power consumption to be 6 Watts (based on general experience) and the voltage of the power adapter is 11.65 Volts, then according to a PoE calculator on the Internet the AX23 would only receive 8.78 Volts at the end of the 50 m Cat5e cable when using 2 wire pairs (most common).

I think with such a long cable you would require the special type of PoE injector adapters that transform the voltage up to a much higher level and then regulate it down again to the voltage required by the network device that is to be powered via PoE.

  @woozle Thanks for the great reply. I have measured the voltage at the end of the cable at 11.5 on the stock adapter and 11.9 on another but I suppose it drops to what you suggest when drawing current, a bit like a garden hose when the taps not fully open? I'm a steam fan, never understood electricity !

Thanks.

P.S. Ive ordered a 50m extension lead with 4 outlets, be able to make tea too :0)

That's probably the best solution. :-)

By the way, I am pretty sure these Lindy Passive PoE adapters would have limited the network connection to 100 Mbps.
