CHAPTER 1
Getting to Know Your Switch
1.1 Introduction
This chapter introduces the main features and applications of the Switch.
The Switch is a layer-2 standalone Ethernet switch with additional layer-2, layer3, and layer-4 features suitable for metro ethernets. The Switch has eight 10/100
Mbps Ethernet ports and two mini-GBIC slots. It also has two GbE dual personality
interfaces with each interface comprising one mini-GBIC slot and one 10/100/
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.
See Chapter 22 on page 165 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.
MES-2110 User’s Guide
19
Chapter 1 Getting to Know Your 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
20
MES-2110 User’s Guide
Chapter 1 Getting to Know Your Switch
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
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 11 on page 83.
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 recabling.
MES-2110 User’s Guide
21
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
1.1.5 Metro Ethernet
The Switch is ideal for connecting users to an Ethernet network that spans a
metropolitan area.
In the following example, the Switch is one of many switches that connect users in
the metropolitan area to the Internet. The metro ethernet is based on a star (or
hub-and-spoke) topology, though other topologies, such as ring or mesh, are also
22
MES-2110 User’s Guide
Chapter 1 Getting to Know Your Switch
possible. The Switch is connected to the backbone and the metropolitan servers
over an optical network that provides higher bandwidth than copper.
Figure 5 Metro Ethernet
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 37.
• 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.
• SNMP. The Switch can be monitored by an SNMP manager. See Section 20.3 on
page 146.
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.
MES-2110 User’s Guide
23
Chapter 1 Getting to Know Your Switch
• 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 Switch. You
could simply restore your last configuration.

CHAPTER 2
Hardware Installation and
Connection
2.1 Installation Scenarios
This chapter shows you how to install and connect the Switch.
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 important for
enclosed rack installations.
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.
4 Remove the adhesive backing from the rubber feet.
MES-2110 User’s Guide
25
Chapter 2 Hardware Installation and Connection
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 6 Attaching Rubber Feet
Note: Do NOT block the ventilation holes. Leave space between devices when
stacking.
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 rack-mounting 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.
26
MES-2110 User’s Guide
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 topheavy. Take all necessary precautions to anchor the rack securely before
installing the unit.
2.3.2 Attaching the Mounting Brackets to the Switch

LABEL DESCRIPTION
Two Dual
Personality
Interfaces
Console Port The console port is for local configuration of the Switch.
Each interface has one 1000 Base-T copper RJ-45 port and one mini-GBIC
slot, with one port active at a time.
• 10/100/1000 Mbps RJ-45 GbE Ports:
•Mini-GBIC Slots:
3.1.1 Console Port
For local management, you can use a computer with terminal emulation software
configured to the following parameters:
• VT100
Connect these Gigabit Ethernet ports to high-bandwidth backbone
network Ethernet switches.
Use mini-GBIC transceivers in these slots for fiber-optic or copper
connections to backbone Ethernet switches.
• Terminal emulation
• 9600 bps
• No parity, 8 data bits, 1 stop bit
• No flow control
Connect the male 9-pin end of the console cable to the console port of the Switch.
Connect the female end to a serial port (COM1, COM2 or other COM port) of your
computer.
3.1.2 Gigabit Ethernet Ports
The Switch has 1000Base-T auto-negotiating, auto-crossover Ethernet ports. In
10/100/1000 Mbps Fast Ethernet, the speed can be 10 Mbps, 100 Mbps or 1000
Mbps and the duplex mode can be half duplex or full duplex.
An auto-negotiating port can detect and adjust to the optimum Ethernet speed
(10/100/1000 Mbps) and duplex mode (full duplex or half duplex) of the
connected device.
An auto-crossover (auto-MDI/MDI-X) port automatically works with a straightthrough or crossover Ethernet cable.
30
Two of the 1000Base-T Ethernet ports are paired with a mini-GBIC slot to create a
dual personality interface. The Switch uses up to one connection for each miniGBIC and 1000Base-T Ethernet pair. The mini-GBIC slots have priority over the
Gigabit ports. This means that if a mini-GBIC slot and the corresponding GbE port
are connected at the same time, the GbE port will be disabled.
