Ethernet Topology

Learn about the Ethernet connections between the ETX-1620x rack I/O panel, PXIe controller, rack control unit (RCU), MOXA switch, and other components.

Figure 25. Ethernet Block Diagram


Note Ethernet ports in the MOXA switch that are not depicted in the block diagram are unused.
Note When Ethernet connections go through the MOXA switch, the connection speed is limited to 10/100BaseTX.

The following table describes the IP addresses the system expects for its internal devices. Using different IP addresses may cause issues with Maintenance Software and composite instrument drivers. Unless otherwise specified, the expected subnet mask is 255.255.0.0.
