SerDes ports. This system has two working modes, the Standalone mode and the PCIe Endpoint mode. The motherboard, inside the T2080RDB-PC, is a PCIe form factor card and it is installed in a custom 1U chassis. The system will be in standalone mode by default and you can remove the PCIe from its chassis for PCIe Endpoint mode operation.

2.7 Ethernet controllers The T2080 supports two Ethernet Controllers (EC), which can connect to Ethernet PHYs using MII or RGMII protocols. On the T2080RDB-PC, the EC1 and EC2 ports only operates in RGMII mode. Both ports connect to Realtek RTL8211 PHYs.
However, EMI2 is only used with XFI based PHYs, which uses 1.2 V pull-up. EMI1 is used with all other non-XFI based PHYs, including the onboard RGMII PHYs.
