7.4.4 Connect PACE-Net Ethernet
The PT2002-A1 provides 2 Ethernet sockets at the PT2001-A1 mother board.
Always connect port A (ETH A) with an Ethernet switch.
A redundant Ethernet connection can also be established by connecting socket
port B (ETH B) with an Ethernet switch. It can be the same switch or, for higher
redundancy, another Ethernet switch in the system. If the connection on port A
fails, the PT2002-A1 uses automatically port B for the communication.
