EXPANSION LAN SWITCH
General Description
The expansion LAN switch provides an interface from the ACE3600 CPU (on the master RTU
frame) to up to seven expansion modules (on I/O expansion frames), or up to 13 expansion
modules when two switches are used. This enables the use of up to 110 I/O modules. The
expansion modules can be co-located with the switch (installed in the same 19” frame or
cabinet) or distributed in other locations.
The expansion LAN switch is installed in the main frame only, in either of the first two I/O
module slots.
