5.6 Control Plane Fabric/Gigabit Ethernet
The SBC347A supports a total of two 10GBASE-T Ethernet channels, which
collectively make up the Control Plane interface. The channels are called ETH0
and ETH1. The actual configuration of the Control Plane depends on the build
variant of the SBC347A (described below).
ETH0 and ETH1 are provided by the Intel X540 Controller. The interface supports
10/100/1000/10GBASE-T, auto-negotiation, automatic Musical Instrument Digital
Interface (MIDI) crossover and polarity.
NOTE
User may experience dropped Ethernet packets during cold start (below -25 °C) or during thermal
transition.
