The ComNet CNGEMC4+2[POE][HO]/M is a four port intelligent Media Converter. It provides four 10/100/1000Base-T(X) copper ports and two 100/1000Base-FX SFP ports. The CNGEMC4+2[POE][HO]/M provides exclusive functionality for easy field deployment including DIP switch based operation of RSFP (redundant SFP) for creating redundant fiber connections and MUX feature for port isolation preventing network video flooding of multicast traffic. Copper ports 1 through 4 can optionally supply up to thirty (30) watts of power per port based on the IEEE 802.3at standard. An optional High Output (HO) version is also available that can supply up to sixty (60) watts of PoE from copper ports 1 through 4. This product is fully compatible with the ComNet exclusive CopperLine® SFP modules for operation over extended distance UTP or Coax cable. The ComNet exclusive Port Guardian feature provides additional cybersecurity protection by enabling physical port lockout in the event that an existing cable is disconnected and prevents a potential network incursion using common spoofing techniques.

Features for CNGEMC4+2[POE][HO]/M Series

  • Electrical port supports Auto-Negotiation for 10 Mbps, 100 Mbps or 1000 Mbps, full duplex or half duplex data.
  • SFP Ports support 100 or 1000 Mbps full duplex data
  • SFP Ports compatible with CopperLine CL-SFP modules
  • IEEE802.3at Power over Ethernet (PoE+)
  • Several features can be enabled with no programming required: MUX; Port Multiplexing; RSFP; Redundant SFP Ports
  • Automatic MDI/MDI-X crossover
  • Designed to meet full compliance with the environmental requirements (ambient operating temperature, mechanical shock, vibration, humidity with condensation, high-line/low-line voltage conditions, and transient voltage protection) of NEMA TS-1/TS-2 and the Caltrans Specification for Traffic Signal Control Equipment.
  • The port count makes this unit ideal for those applications where rack density or shelf-space may be limited.
  • Voltage transient protection on all power and signal input/output lines provides protection from power surges and other voltage transient events.
  • Redundant AC/DC inputs for uninterrupted operation in the event of a loss of operating power or a power supply failure
  • Compact form-factor saves space in those installations where space may be at a premium.
  • Allows compatible surface mount ComNet products to be adapted to DIN rail installation
  • Port Guardian prevents network intrusion through intelligent physical port lockout
