摘要：An apparatus and method for enabling Cisco legacy power to support IEEE802.3af standard power. A network power system capable of delivering data terminalequipment power via a media dependent interface (MDI) includes power source

equipment according to a first power via MDI scheme such as Cisco legacy power and atleast one powered device according to a second power via MDI scheme such as IEEEstandard power. A power compatibility module is inserted between the power sourceequipment and the powered device to enable the power source equipment to appearaccording to the first power via MDI scheme and the powered device to appear accordingthe second power via MDI scheme. In one embodiment, the module includes switches, aDC/DC converter, an IEEE power source equipment circuit, and an isolator. The modulemay optionally include a user signaling device for communicating operating conditions ofthe module to a user.
