5.7 Connecting communication
• Before connecting communication, check that the HW module has the correct
communication interfaces.
The communication module is located in slot A2.
See the technical manual for the communication
interfaces.
Check the allowed minimum bending radius from the
optical cable manufacturer.
5.7.1 Connecting protection communication
Port X6/LD of the communication module is used for protection communication
connection. As the optional SFP transceiver is not attached to the port at the time
of delivery, it needs to be installed to port X6/LD if protection communication is
used.
1. Remove the dust cap from port X6/LD to expose the SFP socket.
