TCP/IP based connections to each device (from a PCCU instance for each). The host connects to any
available Ethernet port on any of the XIOs (physical connection not shown).

9.4.3 Remote access by host
Network communication is necessary for remote management of the device over a TCP/IP network
(customer private network). Hosts can have remote access to the XIO when both the host and the XIO are
configured with valid IP parameters to connect to the customer network.
In 4-port switch mode, the XIO requires only a single valid IP address which the host can use to establish
connection over the network.
Host connects to XIO on field network switch (star topology)
XIO connects to the network in star topology. Figure 9-7 shows the network connection for the XIO on a
field switch (3) in a star topology implementation. This connection requires that a network switch is
available in the field and that there are enough ports available for additional equipment or XIOs.
IMPORTANT NOTE: When the XIO is in 4-port switch mode, you can use any of the
Ethernet ports (A1, A2, B1 or B2) to connect to the network switch. You can move the
connection to any of the ports without the need to reconfigure the IP address of the XIO.
Keep consistency in selecting the ports for network connection when installing multiple
XIOs, for example use A1 port.
