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 one-to­one, one-to-many, many-to-one and stand-alone.

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 and LLDP (Link Layer Discovery Protocol) 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
