3.6 Connect expansion modules
3.6.1 Connect additional devices with Ethernet
Multiple external devices such as an XFC, XRC, analyzer, or an additional RMC can connect to the RMC
Ethernet port.
IMPORTANT NOTE:
Each device that connects to an Ethernet port requires a valid IP address for
TCP/IP communications. If the devices do not each have a valid IP address, they cannot
communicate over the network. For additional information on Ethernet connec
tion scenarios see
section 10, Ethernet connectivity scenarios.
Figure 3-10 illustrates how Ethernet port 2 supports connecting to multiple RMCs.
