Industrially Hardened 10/100 Mbps 3 Port Intelligent
Ethernet Switch With Integrated Contact Closure Server
CNFE3FX1TX2C/M Series
PORT
GUARDIAN
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 oneto-one, one-to-many, many-to-one and stand-alone use through JSON frames for integration into third party systems.
The internal/self-contained 9 to 36 VDC or 24 VAC power supply features redundant power inputs, for the highest
possible reliability. The simple to install, CNFE3FX1TX2C/M Series is DIN-rail or panel-mountable, and is ideal
for mission-critic al applications where very high levels of reliability and network availabili ty are of the utmost
importance.
FEATURES
› Full duplex transmission of 10/100 Mbps Ethernet:
(2) 10/10 0BA SE-T X po r t s and
(1) 100BASE-FX SFP port
› Extended ambient operating temperature range of -40º to +75º C,
for use in virtually any environment. Optional conformal coating
available for humidity with condensation or airborne particulate
matter environments
› Uses customer-installed ComNet SFPs for compatibility with a
wide range of optical fibers, optical connec tor types, and optical
transmission distances of up to 120 km
› Integrated contact closure server supports wet/dry inputs and user
selectable normally open or normally closed form A relay outputs.
› SNMP v1/v2c support allow for monitoring and control of device and
contact closure status.
› Redundant power inputs for extremely high levels of reliability and
availability
› No fans or forced-air cooling required; cooling via natural
convection eliminates unreliable and troublesome fans/moving
parts for improved reliability
› Indicating LEDs confirm operating status of the switch, link and
contacts for ease in troubleshooting
› Summary fault alarm provides a local or remote indication via dry
contact closure in the event of loss of optical link or operating power
› Rugged 19-gauge galvanized & powder-coated steel enclosure
may be DIN-rail or panel-mounted
› Made in the USA
› Lifetime Warranty
