Functionality
Ethernet channel supervision SCHLCCH represents X1/LAN, X2/LAN and X3/LAN
Ethernet channels.
An unused Ethernet port can be set "Off" with the setting
Configuration/
Communication/Ethernet/Rear port(s)/Port x Mode
. This setting closes the port from
software, disabling the Ethernet communication in that port. Closing an unused Ethernet
port enhances the cyber security of the relay.
