Ethernet 10/100 (EMAC) Port
The main board contains a MICREL PHY device (KSZ8051) operating at 10/100 Mbps. The board sup-
ports MII and RMII interface modes.
The two independent PHY devices embedded on CM and MB boards are connected to independent RJ-
45 connectors with built-in magnetic and status LEDs.
Additionally, for monitoring and control purposes, LED functionality is carried on the RJ45 connectors to
indicate activity, link, and speed status information for the respective ports.
