Syntax Conventions
• The ES-3124, ES-3124PWR, ES-3124-4F, and ES-3124F may be referred to as the
“Switch”, the “device”, the “system” or the “product” in this User’s Guide. Distinction is
made where necessary.
• Product labels, screen names, field labels and field choices are all in bold font.
• A key stroke is denoted by square brackets and uppercase text, for example, [ENTER]
means the “enter” or “return” key on your keyboard.
• “Enter” means for you to type one or more characters and then press the [ENTER] key.
“Select” or “choose” means for you to use one of the predefined choices.
• A right angle bracket ( > ) within a screen name denotes a mouse click. For example,
Maintenance > Log > Log Setting means you first click Maintenance in the navigation
panel, then the Log sub menu and finally the Log Setting tab to get to that screen.
• Units of measurement may denote the “metric” value or the “scientific” value. For
example, “k” for kilo may denote “1000” or “1024”, “M” for mega may denote “1000000”
or “1048576” and so on.
• “e.g.,” is a shorthand for “for instance”, and “i.e.,” means “that is” or “in other words”.

CHAPTER 1
Introducing the Switch
This User’s Guide covers the following models: ES-3124, ES-3124-4F, ES-3124-PWR and
ES-3124F. The following table lists features that are specific to individual models.

See Chapter 38 on page 283 for a complete list of features that are common to all of the
models.
This chapter introduces the main applications and features of the Switch. It also introduces the
ways you can manage the Switch.
1.1 Overview
This section shows a few examples of using the Switch in various network environments.
1.1.1 Backbone Application
The Switch is an ideal solution for small networks where rapid growth can be expected in the
near future. The Switch can be used standalone for a group of heavy-traffic users. You can
connect computers directly to the Switch’s port or connect other switches to the Switch.
In this example, all computers share high-speed applications on the server. To expand the
network, simply add more networking devices such as switches, routers, computers, print
servers, etc.

1.1.2 Bridging Example
The Switch can connect different company departments (RD and Sales) to the corporate
backbone. It can alleviate bandwidth contention and eliminate server and network bottlenecks.
All users that need high bandwidth can connect to high-speed department servers via the
Switch. You can provide a super-fast uplink connection by using a Gigabit Ethernet/miniGBIC port on the Switch. Moreover, the Switch eases supervision and maintenance by
allowing network managers to centralize multiple servers at a single location.

1.1.3 High-performance Switched Example
The Switch is ideal for connecting two networks that need high bandwidth. Switching to
higher-speed LANs such as ATM (Asynchronous Transmission Mode) is not feasible for most
people due to the expense of replacing all existing Ethernet cables and adapter cards,
restructuring your network, and complex maintenance. The Switch can provide the same
bandwidth as ATM at much lower cost while still being able to use existing adapters and
switches. Moreover, the current LAN structure can be retained as all ports can freely
communicate with each other.
In the following example, two Switches use trunking to connect two networks.

Chapter 1 Introducing the Switch
1.1.4 IEEE 802.1Q VLAN Application Examples
This section shows a workgroup and a shared server example using 802.1Q tagged VLANs.
A 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) unless such traffic first goes through a router.
For more information on VLANs, refer to Chapter 8 on page 79.
1.1.4.1 Tag-based VLAN Example
Ports in the same VLAN group share the same frame-broadcast domain and thus increase
network performance through reduced broadcast traffic. VLAN groups can be modified at any
time by adding, moving or changing ports without any re-cabling.

1.1.4.2 VLAN Shared Server Example
Shared resources such as a server can be used by all ports in the same VLAN as the server, as
shown in the following example. In this example, only ports that need access to the server
need belong to VLAN 1. Ports can belong to other VLAN groups too.
Figure 5 Shared Server Using VLAN Example
1.2 Ways to Manage the Switch
Use any of the following methods to manage the Switch.
• Web Configurator. This is recommended for everyday management of the Switch using a
(supported) web browser. See Chapter 4 on page 47.
• Command Line Interface. Line commands offer an alternative to the Web Configurator
and may be necessary to configure advanced features. See the CLI Reference Guide.
• FTP. Use File Transfer Protocol for firmware upgrades and configuration backup/restore.
See Section 29.8 on page 237.

ES-3124 Series User’s Guide
• SNMP. The device can be monitored and/or managed by an SNMP manager. See Section
30.3 on page 240.
1.3 Good Habits for Managing the Switch
Do the following things regularly to make the Switch more secure and to manage the Switch
more effectively.
• Change the password. Use a password that’s not easy to guess and that consists of
different types of characters, such as numbers and letters.
• Write down the password and put it in a safe place.
• Back up the configuration (and make sure you know how to restore it). Restoring an
earlier working configuration may be useful if the device becomes unstable or even
crashes. If you forget your password, you will have to reset the Switch to its factory
default settings. If you backed up an earlier configuration file, you would not have to
totally re-configure the Switch. You could simply restore your last configuration.
