Getting to Know Your Switch

This chapter introduces the main features and applications of the Switch.

1.1 Introduction

The Switch is a layer-2 standalone Ethernet switch. There are three models of the Switch.

Table 1 Switch models and features

MODEL	DISTINGUISHING FEATURES
ES3500-24	24 10/100 Ethernet ports
	4 dual-personality interfaces - 10/100/1000 Mbps Ethernet or 1000 Mbps
	Fiber.
ES3500-24HP	24 10/100 Ethernet ports: only these can supply PoE.
	4 dual personality interfaces: 10/100/1000 Mbps Ethernet or 100/1000
	Mbps Fiber.
ES3500-8PD	8 10/100 Ethernet ports.
	2 dual personality interfaces: 10/100/1000 Mbps Ethernet or 100/1000
	Mbps Fiber.
	Only port 9 can receive power from a PoE switch
	All 10 ports support Green Ethernet to reduce switch port power
	consumption.

Dual-personality interfaces comprise one RJ-45 port and one mini-GBIC slot, with either a port or a 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.

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.

ES3500 Series 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

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.

20

ES3500 Series User’s Guide

Chapter 1 Getting to Know Your Switch

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 9 on page 99.

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.

ES3500 Series 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 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 1038 IP 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 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.

•FTP. Use FTP for firmware upgrades and configuration backup/restore. See Section 38.8 on page 289.

•SNMP. The Switch can be monitored by an SNMP manager. See Section 39.3 on page 292.

22

ES3500 Series User’s Guide

Chapter 1 Getting to Know Your Switch

•Cluster Management. Cluster Management allows you to manage multiple switches through one switch, called the cluster manager. See Chapter 42 on page 321.

1.3Good 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.

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. The following table shows how each model can be mounted.

Table 2 Installation Scenarios

MODEL	MOUNTING TYPE
ES3500-24	19” rack-mounted
ES3500-24HP	19” rack-mounted
ES3500-8PD	Desktop (rack-mountable)

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

1Make sure the Switch is clean and dry.

2Set 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.

3Make sure there is enough clearance around the Switch to allow air circulation and the attachment of cables and the power cord.

2.3Mounting 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.

Chapter 2 Hardware Installation and Connection

2.3.1Rack-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.

2.3.1.1Precautions

•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.

2.3.2Attaching the Mounting Brackets to the Switch

1Position 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.

Chapter 3 Hardware Overview

3.1.1 Console Port

For local management, you can use a computer with terminal emulation software configured to the 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.

3.1.2 Ethernet Ports

The Switch has 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 several dual-personality interfaces, (see Figure 9 on page 28 and Figure 13 on page 29), each of which consists of an RJ-45 Ethernet port and SFP slot pair. The Switch activates one connection of each RJ-45 and SFP slot pair. The SFP slots have priority over the RJ-45 ports. This means that if an RJ-45 port and the corresponding SFP slot are connected at the same time, the RJ45 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

•Duplex: Auto

•Flow control: Off

•Link Aggregation: Disabled
