Chapter 3 Router Hardware Description
Gigabit Ethernet Ports
The router features two Gigabit Ethernet (GE) ports that can be used to enable WAN connectivity to a
primary substation or a control center. The ports are shown in
GE ports are labelled on the router and referred to in software.

The GE ports automatically detect the type of any connected cable (fiber or copper) and then switch to
the corresponding mode (fiber or copper). When both cables types are connected to the router, the first
cable that establishes a link is enabled.
