CNGE8MS

8-PORT MANAGED GIGABIT SWITCH

v2.0 Sept 2012

The ComNet™ CNGE8MS is an 8-port Managed Ethernet Switch designed to
reliably operate in harsh, environmentally challenging applications. It features
four (4) 1000BASE-TX and four (4) gigabit combo ports. The four combo ports are
10/100/1000Mbps configurable for either Cat5-e copper, or multimode or single­mode optical fiber by the use of optional ComNet SFPs for connector type and
distance. Exclusive to ComNet is C-Ring, a feature that protects the network from
interruptions or temporary malfunctions with fast recovery technology. Legacy ring
allows the switch to be used in an existing ring of ComNet X-Ring enabled switches.
Redundant DC inputs are included for uninterrupted operation in the event of a power
supply failure. The electrical ports support the 10/100/1000Mbps Ethernet IEEE802.3
protocol, and auto-negotiating and auto-MDi/MDiX features are provided. These
network-managed layer 2 switches are optically and electrically compatible with any
IEEE802.3 compliant Ethernet device. The CNGE8MS is DIN-rail or wall-mountable.

Overview

Introduction

The CNGE8MS is a powerful managed industrial Ethernet switch containing many unique features.
These switches can work under a wide temperature range, dirty environmental and humidity
conditions.

WEB-based, TELNET, Console port or other third-party SNMP software can manage the
CNGE8MS as well. The switch can be managed by a useful utility called eConsole, a powerful
network management software. With its user-friendly and powerful interface, multiple switches
can be easily configured at the same time, and switches’ statuses monitored.

Software Features

» Supports Ring Coupling, Dual Homing over C-Ring technology

» Supports SNMPv1/v2c/v3 & RMON & Port base/802.1Q VLAN Network Management

» Event notification by Email, SNMP trap and Relay Output

» Web-based, Telnet, Console, CLI configuration

» Enable/disable ports, MAC based port security

» Port based network access control (802.1x)

» VLAN (802.1q) to segregate and secure network traffic

Mounting the CNGE8MS on a Wall

Step 1: Remove Din-Rail kit.

Step 2: Use the included screws to attach the wall mount panel as shown in the diagram below.

The screw specifications are shown in the following two pictures. In order to prevent switches from
being damaged, the screws should not be larger than the size that used in CNGE8MS switch.

This section details configuration through the Web browser.

About Web-based Management

An embedded HTML web site resides in the flash memory on the CPU board. It contains
advanced management features and allows you to manage the switch from anywhere on the
network through a standard web browser such as Microsoft Internet Explorer.

The Web-Based Management function supports Internet Explorer 5.0 or later. It is based on Java
Applets with an aim to reduce network bandwidth consumption, enhance access speed and
present an easy viewing screen.

Note: By default, IE5.0 or later version does not allow Java Applets to open sockets. You need to

explicitly modify the browser setting in order to enable Java Applets to use network ports.

Preparing for Web Management
