PowerDsine announced a 4-channel Power over Ethernet Manager developed jointly with Motorola. The four-port IEEE 802.3af-compliant chip integrates power, analog and advanced digital logic functions into one device. Its use in low-port count Ethernet switches, Small Office Home Office (SOHO) routers and midspans allows next generation network devices to share power and data over the same cable. PowerDsine already offers a 12-port PoE solution. The two chips could be used in combination, enabling switch manufacturers to create autonomous self-maintained PoE designs from 4 to 48 ports, with detection, real-time protection and AC or DC disconnection. http://www.powerdsine.com/
