CHAPTER 1
Getting to Know Your Switch
This chapter introduces the main applications and features of the Switch. It also
introduces the ways you can manage the Switch.
1.1 Introduction
The GS2200-48 is a stand-alone layer 2 Gigabit Ethernet (GbE) switch. It comes
with 44 100/1000 Mbps Ethernet ports, 4 Dual Personality interfaces (each
consisting of one RJ-45 Gigabit port and one slot for a mini-GBIC tr ansc eiver (SFP
module) with one port active at a time) and two mini-GBIC transceivers for fiberoptic uplink connections.
This section shows a few examples of using the Switch in various network
environments.
See Chapter 41 on page 329 for a full list of software features available on the
Switch.
1.1.1 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
GS2200-48 User’s Guide
23
Chapter 1 Getting to Know Your Switch
connect to high-speed department servers via the Switch. You can provide a fast
uplink connection by using the Gigabit uplink ports on the Switch.
Figure 1 Bridging Application

Sales
1.1.2 High Performance Switching Example
The Switch is ideal for connecting two geographically dispersed networks that
need high bandwidth. In the following example, a company uses the Gigabit uplink
ports to connect the headquarters to a branch office network. Within the
headquarters network, a company can use trunking to group several physical
ports into one logical higher-capacity link. Trunking can be used with copper
cabling over relatively shorter distances than fiber-optic connections.

1.1.3 Gigabit Ethernet to the Desktop
The Switch is an ideal solution for small networks which demand high bandwidth
for a group of heavy traffic users. Y ou can conn ect computers an d servers directly
to the Switch’s port or connect other switches to the Swit ch. Use the Gigabit uplink
ports to provide high speed access to a data server and the Internet. The uplink
ports support a fiber-optic connection which alleviate the distance limitations of
copper cabling.
In this example, all computers can share high-speed applications on the server
and access the Internet. To expand the network, simply add more networking
devices such as switches, routers, computers, print servers and so on.

Internet
Chapter 1 Getting to Know Your Switch
1.1.4 IEEE 802.1Q VLAN Application Example
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 or more
groups. 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, thus
increasing network performance by reducing broadcast traffic. VLAN groups can
be modified at any time by adding, moving or changing ports without any recabling.
GS2200-48 User’s Guide
25
Chapter 1 Getting to Know Your Switch
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 on the Switch can belong to other VLAN groups too.
Figure 4 Shared Server Using VLAN Example
1.2 Ways to Manage the Switch
Use any of the following methods to manage the Switch.
• Web Co nfigurator. This is recommended for everyday management of the S witch
using a (supported) web browser. See Chapter 4 on page 41.
• 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 31.8 on page 275.
• SNMP. The device can be monitored and/or managed by an SNMP manager. See
Section 32.3 on page 280.
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.
26
• 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.
GS2200-48 User’s Guide
Chapter 1 Getting to Know Your Switch
• 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 y our password, you will hav e 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.

CHAPTER 2
Hardware Installation and
Connection
This chapter shows you how to install and connect the Switch.
2.1 Freestanding Installation
1 Make sure the Switch is clean and dry.
2 Set the Switch on a smooth, level surface strong enough to support the weight of
the Switch and the connected cables. Make sure there is a power outlet nearby.
3 Make sure there is enough clearance around the Switch to allow air circulation and
the attachment of cables and the power cord.
4 Remove the adhesive backing from the rubber feet.
5 Attach the rubber feet to each corner on the bottom of the Switch. These rubber
feet help protect the Switch from shock or vibration and ensure space between
devices when stacking.
Figure 5 Attaching Rubber Feet
Note: Do NOT block the ventilation holes. Leave space between devices when
stacking.
GS2200-48 User’s Guide
29
Chapter 2 Hardware Installation and Connection
Note: For proper ventilation, allow at least 4 inches (10 cm) of clearance at the front
and 3.4 inches (8 cm) at the back of the Switch. This is especially important for
enclosed rack installations.
2.2 Mounting the Switch on a Rack
This section lists the rack mounting requirements and precautions and describes
the installation steps.
2.2.1 Rack-mounted Installation Requirements
• Two mounting brackets.
• Eight M3 flat head screws and a #2 Philips screwdriver.
• Four M5 flat head screws and a #2 Philips screwdriver.
Failure to use the proper screws may damage the unit.
2.2.1.1 Precautions
• Make sure the rack will safely sup port the combined weight of all the equipment
it contains.
• Make sure the position of the Switch does not make the rack unstable or topheavy. Take all necessary precautions to anchor the rack securely before
installing the unit.
2.2.2 Attaching the Mounting Brackets to the Switch
1 Position a mounting bracket on one side of the Switch, lining up the four screw
holes on the bracket with the screw holes on the side of the Switch.
Figure 6 Attaching the Mounting Brackets

2 Using a #2 Philips screwdriver, install the M3 flat head screws through the
mounting bracket holes into the Switch.
