The ComNet CNGE2+2SMS[POE][HO] is a four port intelligent switch with light
management functionality. It provides two 10/100/1000Base-T(X) copper ports and
two 100/1000Base-FX SFP* ports. The CNGE2+2SMS[POE][HO] provides exclusive
functionality for easy field deployment including DIP switch based operation of
RSTP for creating redundant network topologies as well as preventing network
video flooding of multicast traffic when used in a linear or star topology. Ports 1
and 2 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 ports 1 and 2. This product is fully
compatible with the ComNet exclusive CopperLine® SFP modules for operation
over extended distance UTP or Coax cable.
