EM1
2-Port 10/100/1000 Base-T Ethernet NIC, Intel® 82580DB, PCIe I/F to processor
The EM1 module integrates the Intel® 82580 GbE Controller with supporting magnetics and circuitry to provide dual-port gigabit (10/100/1000Base-T) Ethernet network controller functions. NAI Single Board Computer (SBC) boards are typically designed with dual-port NICs. The EM1, with direct-connect PCIe interface, allows for seamless SBC/processor configuration providing access to additional Ethernet communication port functions.
The EM1 is typically integrated/configured directly on NAI SBCs or multifunction I/O boards that support external module PCIe communications interface ports. Direct SBC/processor control of the EM1 is provided through the PCIe interface via the standard/default OS operation/drivers.
