CNGEMC4+2[POE][HO]/M

10/100/1000 MBPS INTELLIGENT

MEDIA CONVERTER WITH OPTIONAL POE+

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 media converter 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.
