Input/Output Ports
LAN1 Port with PoE
This Fast Ethernet port is recognized as first LAN interface in most OSs. It is fully compatible with IEEE802.3af Power over Ethernet standard and passive PoE (non-standard). The board accepts either 12 or 48 V DC input voltage according to the configuration. To use standard PoE power option on this interface, switch jumpers JP3 and JP4 to the 1-2 position. The PoE input can also be switched to 12V non-standard PoE powering (switching JP3 and JP4 to the 2-3 position). The RouterBOARD 51 power injector may be used to power the board with up to 100m (330 ft) long Ethernet cable.
See Connector Index for pinout of the standard cable required for PoE. All cables made to EIA/TIA 568A/B cable specifications will work correctly with PoE. Note that this port supports automatic cross/straight cable correction (Auto MDI/X), so you can use either straight or cross-over cable for connecting to other network devices.
