CHAPTER 1
Getting to Know Your Switch
This chapter introduces the main features and applications of the Switch.
1.1 Introduction
The Switch is a layer-2 standalone Ethernet switch. The Switch has two or four GbE dual personality
interfaces with each interface comprising one mini-GBIC slot and one 100/1000 Mbps RJ-45 port, with
either port or slot active at a time.
This User’s Guide covers the following models: MES3500-24S, MGS3520-28, MGS3520-28F and MGS3520-
50.
With its built-in web configurator, managing and configuring the Switch is easy. In addition, the Switch
can also be managed via Telnet, any terminal emulator program on the console port, or third-party
SNMP management.
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 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.

Figure 1 Backbone Application
1.1.2 Bridging Example
In this example, 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.
