CHAPTER 1
Getting to Know Your Switch
This chapter introduces the main features and applications of the switch.
1.1 Introduction
The ES-1552 is an Ethernet switch with 48 10/100Mbps ports, two RJ-45 Gigabit ports for
stacking and two mini-GBIC slots for fiber connections.
With its built-in web configurator, managing and configuring the switch is easy.
See Appendix A on page 149 for a full list of software features available on the switch.
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 and servers directly to the switch’s port or connect other switches to the
switch.
In this example, all computers can 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
In this example application the switch connects 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/mini-GBIC port on the switch.
Moreover, the switch eases supervision and maintenance by allowing network managers to
centralize multiple servers at a single location.
Figure 2 Bridging Application
1.1.3 High Performance Switching Example
The switch is ideal for connecting two networks that need high bandwidth. In the following
example, use trunking to connect these two networks.
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.

1.1.4 IEEE 802.1Q VLAN Application Examples
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 63.
1.1.4.1 Tag-based VLAN Example
Ports in the same VLAN group share the same frame broadcast domain 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.
Shared resources such as a server can be used by all ports in the same VLAN as the server. In
the following figure only ports that need access to the server need to be part of VLAN 1. Ports
can belong to other VLAN groups too.
