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 use through JSON frames for integration into third party systems.

Features

Full 10/100 Mbps Bandwidth

Uses customer-installed ComNet SFPs for compatibility with a wide range of optical fibers, optical connector types, and optical transmission distances of up to 120 km

Extended ambient operating temperature range of -40˚ C to +75˚ C, for use in virtually any environment. Optional conformal coating for humidity with condensation or airborne particulate matter conditions

SNMP v1/v2c for network management

Redundant power inputs, for extremely high levels of reliability and availability

No fans or forced-air cooling; cooling via natural convection eliminates unreliable and troublesome fans/moving parts, with no periodic maintenance requirements.

Status indicating LEDs provide rapid indication of critical operating parameters.

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 and powder-coated steel enclosure.

Integrated contact closure server supports wet/dry inputs and user selectable normally open or normally closed form A relay outputs.
