CNGE2+2SMS[POE][HO]
10/100/1000 MBPS INTELLIGENT REDUNDANT RING
GIGABIT SWITCH WITH OPTIONAL POE+
v1.4 August 24, 2015
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.

MECHANICAL INSTALLATION INSTRUCTIONS
INSTALLATION CONSIDERATIONS
This product is supplied as Standalone/Surface Mount modules.
Units should be installed in dry locations protected from extremes of
temperature and humidity.
CAUTION: Take care not to press on any of the LEDs.
WARNING: Unit is to be used with a Listed Class 2 power supply.
IMPORTANT SAFEGUARDS:
A) Elevated Operating Ambient - If installed in a closed or multi-unit rack
assembly, the operating ambient temperature of the rack environment may
be greater than room ambient. Therefore, consideration should be given to
installing the equipment in an environment compatible with the maximum
ambient temperature (Tma) specified by the manufacturer.
B) Reduced Air Flow - Installation of the equipment in a rack should be such
that the amount of air flow required for safe operation of the equipment is not
compromised.
