CNGE2+2SMS[POE][HO]

10/100/1000 MBPS INTELLIGENT REDUNDANT RING
GIGABIT SWITCH WITH OPTIONAL POE+

v1.4 August 17, 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.

Overview

Introduction

The CNGE2+2SMS is a light managed, hardened Ethernet switch that contains many features.
The switch will work under a wide variety of temperature, dirty and humid conditions. It can be
managed through WEB, USB Console or other third-party SNMP software. With the easy to use
and intuitive web and CLI interfaces, the switch can be easily monitored by a utility called eVision,
which is part of the ComNet eConsole software suite.

eConsole is network management software that is very effective. With easy to use and intuitive
interface, you can easily monitor the status of the switches.
