5.2.6 Ethernet 10/100 (EMAC) Port
The main board contains a MICREL PHY device (KSZ8051) handling Ethernet connectivity at 10/100 Mbps. The device
supports MII and RMII interface modes.
There are two independent PHY devices placed on CM and MB boards that connect to two separate RJ-45 connectors
and that contain built-in magnetics and status LEDs. The LEDs are driven by PHY devices to indicate activity, link and
speed status for the respective Ethernet ports.
