I only see one explanation to my problem...<br><br>GXP2000 phones only implement PoE mode A of the IEEE 802.3af protocol, and the power injector does only PoE mode B of the IEEE 802.3af protocol. The switch does mode A.<br>
The problem is that I can't prove this! can't find documentation with this kind of detail. If someone does, please tell.<br><br>Regards,<br>Ricardo Carvalho.<br><br><br>
