Insert the Ethernet cable into the sockets of the X1 and X2 interfaces.
The X1 and X2 interfaces for RJ45 plug-in connectors are equivalent.
note!
To ensure electromagnetic compatibility (EMC)
▶
Only use shielded Ethernet cables.
▶
Connect the Ethernet cables of all devices to the top hat rail to
ground the cable shielding.
