provides power for powered devices (PDs) by using the Ethernet PoE electrical interface board.
l When an AC power supply is inserted into slots PWR1 to PWR4, it provides power for the entire device.
l The S7706 has PoE chassis and non-PoE chassis, which are identified by the nameplates and silkscreens
