3.2.3. USB C :

This connection serves 2 purposes

  1. GIGE / USB Bridge (Port 8 of the 88Q6113)

  2. Data Connection for VSPY 3 and configuration using neoVI Explorer

3.2.4. Ports 9/10: 10GBASE-T Ports:

The RAD Epsilon uses a standard RJ-45 connector for 10GBASE-T ports.

10GBASE-T Ports

RJ45

The standard RJ-45 jacks on RAD Epsilon have a pair of integrated LEDs that provide information about the RAD-Epsilon’s conventional 10 Gigabit Ethernet connections.
