The SELV interface LL out 7 - 12 is optional. Please refer to section 6.11,
"Option LLO-2 (Low Level Outputs)" on page 90.
5.2.1 Ethernet Ports ETH1 and ETH2
The two PoE ( P ower o ver E thernet) ports ETH1 and ETH2 are standard
10/100Base-TX (twisted pair) Ethernet ports. They support auto crossing
(auto MDI/MDIX). This means you can use a standard cable or a cross-over
Ethernet patch cable.
Since the CMC test set can be controlled over a network, any distance
between the controlling computer and the test set is possible. This enables
direct remote control of the CMC test set, 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.

Note: If your Ethernet ports ETH1 and ETH2 look different, i.e., ETH2 is
the connector version of Fast Ethernet over optical fiber, refer to chapter
