PowerDsine PD64012
The PD64012 implements all real time functions according to IEEE 802.3af-2003, including: detection, classification, and port status monitoring; as well as system level activities such as: power management and MIB support, for system management. The PoE Manager is designed to detect and disable disconnected ports, using both DC and AC disconnect methods, as defined in IEEE 802.3af2003. The PD64012 has two possible working configurations: an Auto mode (stand-alone topology) for basic PoE functions and an Enhanced mode for extended functions.
