The Transition Networks stand alone AC or DC powered Power over Ethernet (PoE) converters are Power Sourcing Equipment (PSE) and are fully compatible with Powered Devices (PD) that comply with IEEE802.3af: 2003 Standard. The PoE converters also include PD signature sensing and power monitoring features per the IEEE802.3af standard.
The PoE converters can opperate in two modes: IEEE 802.3af mode or "legacy mode". In IEEE 802.3af mode the PoEs are fully compatible with devices which comply with the standard. The PoE converters are also capable of inserting power on either the spare pair or data pairs of the Media Dependant Interface (MDI).
"Legacy mode" allows the PoE to be configured for reverse polarity, 12VDC, 24VDC or 48VDC power insertion; in addition this allows connection to non-IEEE802.3af compatible devices.
Different voltages and modes are switch selectable on the PoE media converters.
