Hi,<br><br>Gigaset products like C470IP are using 6.5V/600mA power supply and a power jack I would qualify as a 5,5-2,5mm one.<br>I can see 5V or 7.5V PoE here and there.<br><br>1. Is there a norm attaching power jacks electric and mechanical specifications in telecom or networking devices ?<br>
>From <a href="http://en.wikipedia.org/wiki/Power_jack">http://en.wikipedia.org/wiki/Power_jack</a>, I can read "Most of the other coaxial DC power connectors have no specified voltage association", I would say no.<br>
<br>2. Which PoE injector would best fit with these ?<br>The 5V one or the 7.5V one ?<br><br>Regards<br>
