Hardware description
The ComNet CNFE3FX1TX2C/M series is an industrially hardened three-port intelligent switch
with light management functionality and an integrated contact closure server. The 100BASE-FX
port supports conventional CAT-5e/CAT-6 copper or optical transmission media by selection of
the appropriate ComNet SFP module. A summary fault alarm provides indication via a form c relay
in the event of loss of optical link or operating power. The 10/100BASE-TX ports support both
auto-negotiation and automatic MDI/MDI-X crossover for full and half-duplex operation; manual
MDI/MDI-X switching is not required. The integrated contact closure server is available with 4 or 8
channels and supports individual user selectable wet or dry inputs. Form A relay outputs feature
individual user selection of normally open or normally closed operation via the built-in web GUI.
The contact server supports 4 modes of operation including one-to-one, one-to-many, many-to-
one and stand-alone.
Distances depend on which SFP (Small Form Pluggable) module is used. The two RJ45 Ethernet
connectors auto-negotiate or the configuration may be forced. The optical interface is fixed at
100Mbs.
