5.2.1 ETH1 and ETH2 Ports
Depending on the interface board of your test set, the two PoE Ethernet ( P ower o ver E thernet) ports
ETH1 and ETH2 are either:
• 10/100Base-TX (twisted pair) Ethernet ports (at NET-1 (x) boards)
• or 10/100/1000Base-TX (twisted pair) Ethernet ports (at NET-2 board)
They support auto crossing (auto MDI/MDIX). This means you can use a standard cable or a
cross-over Ethernet patch cable.
Since CMC 850 can be controlled over a network, any distance between the controlling computer and
the test set is possible. This enables direct remote control of CMC 850 , e.g., for end-to-end testing.
The Ethernet ports also provide the basis for the processing of substation protocols according to the
IEC 61850 standard. They allow flexible configurations, e.g., for separation of data traffic from different
network segments or segregation of substation protocol data and test set control commands.
The yellow and green LEDs at each ETH port reflect the port’s operational status. Depending on your
NET-x interface board, their behavior slightly varies → chapter 7.4, "Technical Data of the
Communication Ports" on page 20.
