Chapter 3 Router Hardware Description
Hardware Features
Fast Ethernet (FE) Ports
The router features six Fast Ethernet (FE) ports that can be connected to local network devices, such as
IEDs, sensors, and reclosers. The ports are labeled as follows:
•
ETH 2/3
•
ETH 2/4
•
ETH 2/5
•
ETH 2/6
•
ETH 2/7
•
ETH 2/8
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
Small Form-Factor Pluggable (SFP) Ports
. For
more information about how these ports are used together, see
Combo Ports, page 3-15
.
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.
