I ordered 2 e410s and recived them today. The only problem is that I somehow managed to order the ones without a power supply. I see that the spec sheet says it takes a Standard 802.3af injector. Any idea what the part number is for the power supplies so I can try to order some. I don't have any 802.3af injectors. I have plenty of ePMP injectors but I don't think that is the right voltage.
