This chapter introduces the main features and applications of the Switch.
1.1 Introduction
The Switch is a layer-2 standalone Ethernet switch. The MES3500-24 has 24 10/100 Mbps fast
Ethernet ports. The MES3500-24F has 24 100 Mbps fast Ethernet SFP slots. Both also have 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.
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.
CHAPTER 1
Getting to Know Your Switch
See Chapter 46 on page 333 for a full list of software features available on the Switch.
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
MES3500-24/24F User’s Guide 23
Chapter 1 Getting to Know Your Switch
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.
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.
Figure 3 High Performance Switched Workgroup Application

MES3500-24/24F User’s Guide
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 9 on page 97.
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.
Figure 4 Shared Server Using VLAN Example
Chapter 1 Getting to Know Your Switch
1.1.5 IPv6 Support
IPv6 (Internet Protocol version 6), is designed to enhance IP address size and features. The
increase in IPv6 address size to 128 bits (from the 32-bit IPv4 address) allows up to 3.4 x 10
addresses. At the time of writing, the Switch supports the following features.
• Static address assignment and stateless auto-configuration
• Neighbor Discovery Protocol (a protocol used to discover other IPv6 devices in a network)
• Remote Management using ping SNMP, telnet, HTTP and FTP services
• ICMPv6 to report errors encountered in packet processing and perform diagnostic functions, such
as "ping”
• IPv4/IPv6 dual stack; the Switch can run IPv4 and IPv6 at the same time
• DHCPv6 client and relay
• Multicast Listener Discovery (MLD) snooping and proxy
For more information on IPv6, refer to the CLI Reference Guide.

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 39 .
• Command Line Interface. Line commands offer an alternative to the web configurator and in
some cases are necessary to configure advanced features. See the CLI Reference Guide.
• FTP. Use FTP for firmware upgrades and configuration backup/restore. See Section 37.8 on page
287.
• SNMP. The Switch can be monitored by an SNMP manager. See Section 38.3 on page 290.
• Cluster Management. Cluster Management allows you to manage multiple switches through one
switch, called the cluster manager. See Chapter 41 on page 316.
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 Sw itch. Y ou
could simply restore your last configuration.

Hardware Installation and Connection
This chapter shows you how to install and connect the Switch.
2.1 Installation Scenarios
The Switch can be placed on a desktop or rack-mounted on a standard EIA rack. Use the rubber
feet in a desktop installation and the brackets in a rack-mounted installation.
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 imp o rtant for
enclosed rack installations.
CHAPTER 2
2.2 Desktop Installation Procedure
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.
2.3 Mounting the Switch on a Rack
The Switch can be mounted on an EIA standard size, 19-inch rack or in a wiring closet with other
equipment. Follow the steps below to mount your Switch on a standard EIA rack using a rackmounting kit.
2.3.1 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.
MES3500-24/24F User’s Guide 27
Chapter 2 Hardware Installation and Connection
2.3.1.1 Precautions
• Make sure the rack will safely support the combined weight of all the equipment it contains.
• Make sure the position of the Switch does not make the rack unstable or top-heavy. Take all
necessary precautions to anchor the rack securely before installing the unit.
2.3.2 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 br acket
with the screw holes on the side of the Switch.
Figure 5 Attaching the Mounting Brackets
2 Using a #2 Philips screwdriver, install the M3 flat head screws through the mounting bracket holes
into the Switch.
3 Repeat steps 1 and 2 to install the second mounting bracket on the other side of the Switch.
4 You may now mount the Switch on a rack. Proceed to the next section.
