Information for Canadian Users

The Industry Canada label identifies certified equipment. This certification means that the
equipment meets certain telecommunications network protective operation and safety
requirements. The Industry Canada does not guarantee that the equipment will operate to
a user's satisfaction.

Before installing this equipment, users should ensure that it is permissible to be connected
to the facilities of the local telecommunications company. The equipment must also be
installed using an acceptable method of connection. In some cases, the company's inside
wiring associated with a single line individual service may be extended by means of a
certified connector assembly. The customer should be aware that compliance with the
above conditions may not prevent degradation of service in some situations.

Repairs to certified equipment should be made by an authorized Canadian maintenance
facility designated by the supplier. Any repairs or alterations made by the user to this
equipment, or equipment malfunctions, may give the telecommunications company cause
to request the user to disconnect the equipment.

For their own protection, users should ensure that the electrical ground connections of the
power utility, telephone lines, and internal metallic water pipe system, if present, are
connected together. This precaution may be particularly important in rural areas.

Caution

Users should not attempt to make such connections themselves, but should contact the
appropriate electrical inspection authority, or electrician, as appropriate.

Note

This digital apparatus does not exceed the Class A limits for radio noise emissions from
digital apparatus set out in the radio interference regulations of Industry.

Preface

Congratulations on your purchase of the ES-2008 Ethernet Switch.

About The ES-2008 Series Switches

The ES-2008 switch allows you to easily configure and manage your network via a web
browser. Just click your mouse instead of typing cryptic command strings. Moreover, the
ES-2008 can also be managed via SNMP.

There are four ES-2008 Ethernet switch models.

MODEL DESCRIPTION

ES-2008 Eight port 10/100M Ethernet switch.

ES-2008-SC Eight port 10/100M Ethernet switch with multi-mode fiber port.

ES-2008-SC30 Eight port 10/100M Ethernet switch with single-mode fiber port.

ES-2008-GTP Eight port 10/100M Ethernet switch with one gigabit port.

About this User’s Guide

This manual is designed to guide you through the configuration of your ES switch for its
various applications. All ES models are discussed together in this guide.

Unless specified, images of the ES-2008-SC are used throughout this document. Images
that directly relate to the other two models are used when referring to the key differences
between the models.

Chapter 1

Getting to Know Your ES-2008

The ES-2008 is a multi-port switch that can be used to build high-performance switched
workgroup networks. This switch uses a store-and-forward switching scheme, in which
incoming data frames are first stored in buffer memory and checked for errors before
being forwarded; thus offering minimum delay for high-speed networking. It is the ideal
switch for small-to-medium sized enterprise workgroups, departments or backbone
computing environments.

The embedded web configurator makes managing and configuring the ES-2008 easy,
enabling system management as well as individual port control and monitoring.

In addition, the ES-2008 can be managed via Telnet, the console port, or SNMP.

1.3 Management Methods

The switch supports the following management methods:

• Local console management

• Telnet management

• Web configurator

• SNMP network management

1.3.1 Console and Telnet Management

Managing the switch through the console port requires a direct connection between the
computer and the switch using an RS-232 console cable. You can also telnet into the
switch from any computer on your network (provided you know the IP address of the
switch).

1.3.2 Web Configurator

The switch comes with an embedded HTML web configurator. It offers advanced
management features and allows you to manage the switch from anywhere on the network
through Microsoft Internet Explorer (version 5.0 or later).

1.4 Applications

The switch is ideally suited as a workgroup switch or a bridge for large network
segmentation.

For ES-2008 models that come with a fiber port, you can also use the fiber port to connect
to other network switches. The distance between two switches via fiber cable can be up to
2 Km (multi-mode) or 30 Km (single-mode).

1.4.1 Standalone Workgroup

The switch can be used as a standalone switch to which computers, servers and printer
servers are directly connected to form a small workgroup.

Figure 1-1 Standalone Workgroup Example

1.4.2 Bridging Application

For enterprise networks where large data broadcasts are constantly processed, this switch
is an ideal solution for department users to connect to the corporate backbone.

In the next illustration, two Ethernet switches with attached computers, print server and
local server, are all connected to the switch. All devices in this network can communicate
with each other through the switch and also access the server.

1.4.3 VLAN Application

VLAN (Virtual Local Area Network) allows a physical network to be partitioned into
multiple logical networks. Stations on a logical network belong to one group. A station
can belong to more than one group. With VLAN, a station cannot directly talk to or hear
from stations that are not in the same group(s); the traffic must first go through a router.

As well as security, VLANs also increase network performance by limiting broadcasts to
a smaller and more manageable logical broadcast domain. In traditional switched
environments, all broadcast packets go to each and every individual port. With VLAN,
broadcasts are confined to the members of the VLAN. Note that VLANs are
unidirectional - they only govern outgoing traffic.

Port-based VLANs are VLANs where the packet forwarding decision is based on the
destination MAC address and its associated port.

Hardware Description and

Installation

This chapter describes the switch hardware and installation

2.1 Hardware Installation

The switch is suitable for an office environment where it can be placed on a desktop.

Step 1. Make sure the switch is clean and dry.
Step 2. Attach the supply rubber feet to the bottom of the switch.
Step 3. Set the switch on a smooth and sturdy flat space strong enough to support the

weight of the switch and the connected cables. Make sure there is a power
outlet nearby.

Step 4. Make sure there is enough clearance around the switch to allow air circulation

and the attachment of cables and the power cord.

Do not block the ventilation holes. Leave space between switches

when stacking.

2.2 Hardware Connections

2.2.1 Front Panel

The front panel of the switch consists of eight auto-sensing, auto-negotiating 10/100Base­TX Ethernet RJ-45 ports and/or one 100Base-FX fiber or gigabit port.

The LEDs are also located on the front panel of the switch.

2.2.2 The Ethernet Connections

Auto-Sensing 10/100Base-TX RJ-45 Ports (Auto MDI/MDIX)

The ES-2008 has eight auto-negotiating, auto-sensing 10/100Base-TX Ethernet RJ-45
ports. All these ports support auto-sensing, a built-in function that automatically
recognizes the type (straight/crossover) of the attached cable. This feature effectively
removes all wiring troubles caused by a cable type mismatch. Although a crossover cable
is usually required to cascade a switch to another switch, auto MDI/MDI-X lets you use a
normal straight cable to do the task.

Auto-Negotiating 10/100Base-TX RJ-45 Ports

The auto-negotiation feature allows the switch to detect the speed of incoming
transmission and adjust appropriately without manual intervention. It allows data transfers
of either 10 Mbps or 100 Mbps in either half-duplex or full-duplex mode depending on
your Ethernet network.
