The electricity is carried on different pins in a cisco poe injector. Just because they both support the same standard doesn't mean they were implemented the same.

Although when I plugged these phone to a PoE capable Cisco Switch it worked without a problem! Knowing that all these three equipments implement IEEE 802.3af protocol, why doesn't it work with the Cisco power injector? Anyone also had this problem before? Thanks, Ricardo Carvalho.
