Host connects to XIO daisy-chained to RMC
Figure 10-8
shows the network connection for the XIO through an RMC-100 in a daisy-chain topology. This
connection requires that the RMC-100 Ethernet interfaces are configured in 1 Network mode. This mode
allows the RMC-100 to behave as a 2-port switch to switch traffic between the network and the XIO. This
scenario may be necessary when there are not additional ports available on a field network switch.
IMPORTANT NOTE: When the XIO is in 4-port switch mode, any of the Ethernet ports (A1,
A2, B1 or B2) are usable to connect to the RMC-100. Move the connection to any of the
ports without reconfiguration of the IP address of the XIO.
