ID Name
1 Host System with PCCU
2 TCP/IP network
In Figure 4-14, the XIO connects directly to the RMC. Access to the XIO for remote management is
through the RMC which performs the role of a switch.
IMPORTANT NOTE: The RMC must be configured as a 2-port switch to support this connection
scenario (Ethernet port 1 and 2 are configured in 1-Network mode). When the RMC is configured for
2-Network mode (E1 and E2 are configured as separate networks), it is not possible to manage the
XIO from the same network as the RMC. For additional information on different scenarios, see
