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.
