TrustedReview posted a review on the D-Link DES-1316K - Power over Ethernet Switch

Along with most products available today the DES-1316K is an end-span device. It provides power over the same wire pairs as used for data delivery so end devices can be powered directly from the switch. Being fully 802.3af compliant, the switch contains automatic detection circuits that prevent it from sending power to non-compliant terminal devices, ensuring that only those devices that present an authenticated PoE signature will receive power.
