How is Legacy Equipment Protected?
For a terminal to receive power on the Ethernet line it must be designed as such. Special detection routines are performed on each port before power is injected, in order to confirm that the terminal is ready. If equipment is not “Power Enabled” the Power-Hub will not supply power to that port. Equipment that is to be powered over the Ethernet is designed to be compatible with a particular Power-Hub and recognizable by it. PowerDsine Power over Ethernet Application Notes can be downloaded from the PowerDsine Web site. The documents detail how the terminal recognition is performed, and how to build “Power Enabled” equipment. PowerDsine was a founding member of the standards committee. More details can be found at the site: http://grouper.ieee.org/groups/802/3/af/index.html. If a device is incompatible with a Power-mid-span, an external splitter can be installed. The splitter separates the DC voltage and the Ethernet data signal into two separate wires, terminating at a power port and a
