CHAPTER 1
Getting to Know Your Switch
This chapter introduces the main features and applications of the Switch.
1.1 Introduction
Your Switch is a stand-alone, layer-3, Gigabit Ethernet (GbE) switch with two 12
Gigabit stacking ports as well as support for an optional 2-port 10 Gigabit uplink
module. By integrating router functions, the Switch performs wire-speed layer-3
routing in addition to layer-2 switching.
The Switch comes with 24 GbE dual personality interfaces. A dual personality
interface includes one Gigabit port and one slot for a mini-GBIC transceiver (SFP
module) with one port active at a time.
There are two XGS-4728F models. The XGS-4728F DC model requires DC power
supply input of -36 VDC to -72 VDC, 1.5 A Max no tolerance. The XGS-4728F AC
model requires 100 VAC to 240 VAC, 0.8 A power.
With its built-in web configurat or, 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.
See Chapter 49 on page 393 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
connect to high-speed department servers via the Switch. You can provide a

super-fast uplink connection by using the optional 10 Gigabit uplink module on the
Switch.

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 optional 10
Gigabit uplink modules 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 hig h er-capacity link. Trunking can be used if for
example, it is cheaper to use multiple lower-speed links than to under-utilize a
high-speed, but more costly, single-port link.

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 Switch. Use the optional 10
Gigabit uplink module to provide high speed access to a data server and the
Internet. The uplink module supports a fiber-optic connection which alleviates 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.

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 9 on page 95 .
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.

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 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 45 .
• 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 38.8 on page 329 .
• SNMP. The device can be monitored and/or managed by an SNMP manager. See
Section 39.3 on page 334.
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.
28
• 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.
XGS-4728F 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.
