Figure 18-2 Expansion LAN Switch – Front Panel
The ACE3600 expansion LAN switch is configured to prioritize different Ethernet data frame
types. A special EMI protocol, used for communication between the expansion LAN switch
and the main CPU, quickly collects I/O information from the expansion frames to the main
CPU and adds the highest priority and special tags to these Ethernet frames. The switch
recognizes these frames and gives them the highest priority in the buffer queue, higher than the
frames of the standard protocols (MDLC, TCP/IP) used for communication in the ACE3600
system. For this reason, only the ACE3600 expansion LAN switch can be used in an I/O
expansion system.
When an expansion LAN switch is used on an I/O expansion LAN, only the main
CPU and the expansion frames (expansion modules) can be connected to the
expansion switch(es). Any attempt to connect other devices to the expansion
switch(es) may result in unpredictable communication delays between the main CPU
and the expansion frames and malfunction of the expanded RTU.

Communication Ports
The expansion LAN switch includes eight 100BaseT Ethernet communication ports.
