Router Hardware Description
Hardware Features
Specifications
Gigabit Ethernet (GE) Ports
The router features two Gigabit Ethernet (GE) ports for a WAN connection to a primary substation or control center. The
ports are labeled as follows:

ETH 2/1

ETH 2/2
Note: Interfaces ETH 2/1 and ETH 2/2 are also used by the SFP ports. For more information about how these ports are
used together, see the Combo Ports, page 26 .
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.
Specifications
Combo Ports
The two Gigabit Ethernet ports and the two SFP ports are labeled identically (ETH 2/1 and ETH 2/2) because the SFP
and GE interfaces share physical ports on the router. Only one instance of each interface (ETH 2/1 and ETH 2/2) can be
in use at any time.

GE ports: Copper GE connections

SFP modules: Fiber optic GE connections
These ports automatically detect the type of any connected cable (fiber or copper) and then switch to the corresponding
mode (fiber or copper).
Note: If connections are made to both interfaces of the same name (ETH 2/1 or ETH 2/2), the first connection that
establishes a link is the only connection enabled.
