Input/Output Ports
LAN1 Port with PoE
This Fast Ethernet port is recognized as the first LAN interface. It is compatible with passive (non-standard)
Power over Ethernet. The board accepts voltage input from 10 to 28 V DC. It is suggested to use the higher
voltage for power over long cables because of better efficiency (less power is lost in the cable itself and
power supply is more efficient).
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.
