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 24 10/100 Mbps Ethernet ports.
It also has 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.
This section shows a few examples of using the Switch in various network environments.
CHAPTER 1
Getting to Know Your Switch
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

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.

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 91.
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.

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 33.
• 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
281.
• SNMP. The Switch can be monitored by an SNMP manager. See Section 38.3 on page 284.
• Cluster Management. Cluster Management allows you to manage multiple switches through one
switch, called the cluster manager. See Chapter 41 on page 310.
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 Switch. You
could simply restore your last configuration.

following parameters:
• VT100
• 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.
Chapter 3 Hardware Overview
Connect an appropriate power supply to this port.
3.1.2 Ethernet Ports
The Switch has 24 10/100 Mbps auto-negotiating, auto-crossover Ethernet ports. In 10/100 Mbps
Fast Ethernet, the speed can be 10 Mbps or 100 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 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 straight-through or crossover
Ethernet cable.
The Switch has four 1000Base-T Ethernet ports, which are paired with a mini-GBIC slot to create a
dual personality interface. The Switch uses up to one connection for each mini-GBIC and 1000BaseT Ethernet pair. The mini-GBIC slots have priority over the Gigabit ports. This means that if a miniGBIC slot and the corresponding GbE port are connected at the same time, the GbE port will be
disabled.
When auto-negotiation is turned on, a Ethernet port negotiates with the peer automatically to
determine the connection speed and duplex mode. If the peer Ethernet port does not support autonegotiation or turns off this feature, the Switch determines the connection speed by detecting the
signal on the cable and using half duplex mode. When the Switch’s auto-negotiation is turned off,
an Ethernet port uses the pre-configured speed and duplex mode when making a connection, thus
requiring you to make sure that the settings of the peer Ethernet port are the same in order to
connect.
3.1.2.1 Default Ethernet Negotiation Settings
The factory default negotiation settings for the Gigabit ports on the Switch are:
• Speed: Auto
ES3500-24 User’s Guide
27
Chapter 3 Hardware Overview
•Duplex: Auto
• Flow control: Off
• Link Aggregation: Disabled
3.1.2.2 Auto-crossover
All ports are auto-crossover, that is auto-MDIX ports (Media Dependent Interface Crossover), so
you may use either a straight-through Ethernet cable or crossover Ethernet cable for all Gigabit port
connections. Auto-crossover ports automatically sense whether they need to function as crossover
or straight ports, so crossover cables can connect both computers and switches/hubs.
3.1.3 Transceiver Slots
These are slots for mini-GBIC (Gigabit Interface Converter) transceivers or 1000 Mbps Small Formfactor Pluggable (SFP) transceivers. A transceiver is a single unit that houses a transmitter and a
receiver. The Switch does not come with transceivers. You must use transceivers that comply with
the SFP Transceiver MultiSource Agreement (MSA). See the SFF committee’s INF-8074i
specification Rev 1.0 for details.
You can change transceivers while the Switch is operating. You can use different transceivers to
connect to Ethernet switches with different types of fiber-optic or even copper cable connectors.
To avoid possible eye injury, do not look into an operating fiber-optic
module’s connectors.
• Type: SFP connection interface
• Connection speed: 1 Gigabit per second (Gbps)
3.1.3.1 Transceiver Installation
Use the following steps to install a mini-GBIC transceiver (SFP module).
1Insert the transceiver into the slot with the exposed section of PCB board facing down.
2Press the transceiver firmly until it clicks into place.
3The Switch automatically detects the installed transceiver. Check the LEDs to verify that it is
functioning properly.
4Close the transceiver’s latch (latch styles vary).
