Positioning and Installing the Switch

 

 

 

 

Allow adequate ventilation

The switch contains two fans to air-cool the internal circuitry. The air

 

 

is drawn in from the left of the unit and expelled through the outlet

 

 

grills on the right side and the rear.

 

 

To ensure correct airflow, leave 100 mm (4 inches) free space on both

 

 

sides and behind the switch. Do not allow the intake or outlet grills to

 

 

become blocked.

 

On a desktop

To install the switch in a desktop environment:

 

 

1 Find the four rubber feet in the pack that contains the rack

 

 

mounting kit.

 

 

2 Remove the backing strip from each of the four feet.

 

 

3 Attach the four rubber feet to the underside of the switch (to

 

 

ensure that the switch stands firmly).

 

 

4 Place the switch on a stable, flat surface.

 

 

5 Ensure that the air intake (on the left) and fan outlets (on the

 

 

right side and rear) are not blocked.

 

 

Warning The switch’s lifetime and operational reliability can

 

 

be seriously degraded by inadequate cooling.

 

Rack requirements

Install the switch in a standard rack in accordance with IEC 297 (or

 

 

similar); if the minimum outside measurements of the rack are 600 x

 

 

600 mm (23.5 x 23.5 inches), you must allow 190 mm (7.5 inches) of

 

 

space at the rear.

 

Mounting kit

The switch is delivered with a kit to attach it to a standard 19-inch

 

 

equipment rack (with side support rails). The kit contains two mount-

 

 

ing brackets and four screws (for attaching the brackets to the sides

 

 

of the switch).

Connecting the Power

Introduction

After connecting the devices to the switch, connect the power cable.

 

There are certain practical and safety considerations to be made be-

 

fore powering the switch on.

 

 

The Power Cable

 

Ground warning

The switch is delivered with a power cable that fits the power sockets

 

in your country. If this is not the case, contact your dealer immediate-

 

ly and ask for the correct power cable.

Power cable wiring color

The wires in the power cable provided are color coded:

code

 

 

 

Color

Connection

 

 

 

 

Green and yellow

Ground

 

 

 

 

Blue

Neutral

 

 

 

 

Brown

Important for UK use

If the colors of the wires in the power cable provided do not corre-

 

spond with the markings that identify the terminals in your plug:

 

1 Make sure that the green and yellow wire is connected to the

 

terminal marked with the letter E, or with the ground symbol

 

, or is colored green and yellow.

 

2 Make sure that the blue wire is connected to the terminal

 

marked with the letter N or colored black.

 

3 Make sure that the brown wire is connected to the terminal

 

marked with the letter L or colored red.

Power supply to a rack

If the switch is installed in a rack, make sure the rack’s power supply

 

socket has a ground connection and the rack is connected to a branch

 

supply or a power supply socket with a ground connection.

To avoid overloading the circuit and damaging the wiring of the power supply, the power supply to the rack must be adequate to cover the extra power consumed by the switch.

12

C H A P T E R 1 Intel Express 510T Switch

Power up

Powering up the switch Follow these steps to power up the switch:

1Push the female end of the power cable into the main socket (in the rear panel); plug the other end into the power supply outlet.

2Make sure that the Power LED (on the front panel) is green.

If it isn’t green, make sure that the power outlet is working correctly (switched on). If the power outlet is on and the Power LED is not green, then there is a fault within the switch and you must contact your dealer.

3Verify that an LED is lit for each of the front panel ports where a powered on device is connected.

Start-up procedure

Immediately after power-up, the following should happen during

 

start-up:

If the Status LED remains red, then the switch has not started success-

 

fully. Try to restart it; if the switch does not start, contact your dealer.

 

Look at the other front panel LEDs during start-up and check that

 

they are operating correctly.

Default settings after start-

Once the switch has started successfully, installation is complete and

up

the switch is using its default setting (also known as default configu-

 

ration):

 

All ports are enabled.

 

All ports operate in auto-negotiation mode.

 

Spanning Tree is disabled on all ports.

 

Addresses that have been silent for more than 15 minutes are

 

purged from the switch’s address table (the MAC Address Aging

 

time).

 

No access restrictions to Local Management (Telnet).

 

No SNMP restrictions.

 

No permanent MAC address entries defined. A permanent entry

 

is a MAC address that is defined as being permitted only on a

 

certain port. This can be a useful security feature.

 

All ports are in the same VLAN (named <System>) and VLAN

 

mode (Stand-alone mode). VLANs allow you to create virtual

 

networks using specific switch ports, IP addresses, IP subnets

 

and MAC addresses.

 

Flow Control is enabled on all ports.

 

The connection with Local Management is timed-out after 10

 

minutes if there has been no input during this period.

After start-up

This default configuration is adequate for simple workgroup environ-

 

ments to operate in basic switching mode.

 

Although the switch continues to operate without problems, we rec-

 

ommend that you change certain parameters to suit your own require-

 

ments.

group of switches known from here on as a stack, (via SNMP) and

 

monitors their activities.

C H A P T E R 2 Intel Device View

Navigating through Intel

Many commands are available from within Intel Device View. These

 

Device View

are best accessed using mouse actions. However, Windows users can

 

 

also access most of them through the menu bar.

 

 

 

 

The Intel Device View

There are three sections:

 

window

Device Tree — displays the separate branches on your LAN,

 

 

 

 

including a branch showing all unconfigured devices.

 

 

Interactive picture of the switch, or stack — shows the port state

 

 

or the Explorer, which provides port and VLAN details for the

 

 

switch or stack.

 

 

Information section — provides details about diagnostics, traps,

 

 

errors and the system. Using this window, you can show activity

 

 

statistics for the switch (or the stack) and for individual ports.

 

 

Before a switch is contacted

Basic menu bar

Before a switch or stack is contacted, the following commands are

commands

available through the menu bar. The toolbar buttons are for users us-

 

ing Intel Device View in Windows.

File menu

This contains one command, Exit which enables you to exit the Intel

 

Device View. When a switch or stack is open and the configuration

 

has been changed and not saved to the Flash Memory as the perma-

 

nent configuration, you are asked if you want to save the new config-

 

uration before exiting.

 

Device menu

The Device menu contains the following switch commands:

 

Install — enables you to install a new device, which does not

 

have an IP address, in Intel Device View. Can also be accessed

 

by selecting

.

 

 

Manage — enables a switch or stack that has an IP address

 

already assigned to be managed or configured. Can also be

 

accessed by selecting

.

Discover — enables you to set up how the Device Tree discovers devices and users.

Note: do not leave the Subnet Mask blank or set to 0.0.0.0, as Intel Device View will continually broadcast device discovery messages to all networks and use bandwidth.

21

C H A P T E R 2 Intel Device View

A list of IP addresses — contains the last eight switches successfully contacted from Intel Device View. These can be used to manage the switch.

play to your own preferences: the Toolbar and Status Bar can be

 

switched on and off.

 

 

Monitoring menu

This menu gives access to set the Default Preferences for Intel Device

 

View, see “Setting the Preferences”, p. 24.

 

Tools menu

The Tools menu has the following commands:

 

 

Ping — sends ICMP echo packets to the switch. Can also be

 

 

accessed by selecting

.

 

 

A Report Manager — uploads reports, logs and the parameter

 

block from the switch. Can also be accessed by selecting

.

 

A Recovery Manager — regains control of your switch if you

 

have lost contact. This is described in “Recovery Manager”, p. 94.

A DNS-IP conversion tool converts DNS names to IP addresses.

These are described in detail, together with switch specific tools, in the Chapter “Managing the Switch”, p. 71.

Help menu

The Help menu has the following commands for the switch:

 

Help for Intel Device View. Can also be accessed by selecting the

 

 

Help icon

then clicking on the feature of interest

 

Help for switch specific topics.

After a Switch or Stack is Contacted

 

 

 

Commands

When Intel Device View contacts a switch, the basic commands are

 

 

supplemented with:

 

 

Local Management access — provides Telnet access to monitor-

 

 

ing functions embedded in the switch.

 

 

RMON facility — gathers information about the network traffic,

 

 

monitors traffic on subnets and enables you to define alarms on

 

 

the individual ports.

 

 

Stack Synchronization Manager (for stacks only) — enables you

 

 

to establish a stack from a group of switches connected via a

 

 

Matrix Module, or add a switch to an existing stack and then syn-

 

 

chronize their configurations.

 

 

Switch Position Organizer (for stacks only) — enables you to

 

 

move the switches displayed on screen around in the stack.

 

 

Color Code Matrix Ports (for stacks only) — colors the individ-

 

 

ual ports on the Matrix Module. This simplifies the task of trac-

 

 

ing cables, as the ports on the Stack Interface Modules become

 

 

the same color as the corresponding Matrix Module port.

Installing and Managing

 

Switches

Following installation of

After installing Intel Device View, you can add new switches, estab-

Intel Device View

lish or expand stacks of switches, and manage existing switches and

 

stacks.

Adding new switches

To add new switches (that have not been assigned an IP address) to

 

Intel Device View, select Device>Install. The Install Wizard

 

will start and guide you through the installation.

The Install Wizard

The Install Wizard requires that you enter a minimum amount of in-

 

formation to set up the switch for management by Intel Device View.

 

To select the correct new device, you need to know the device’s MAC

 

address. You can find this on a label on the rear panel of the device.

 

You must assign an IP address (and subnet mask) to the switch on

 

your Local Area Network (LAN).

Intel Device View uses this address for configuration and management purposes.

26

C H A P T E R 2 Intel Device View

Matrix Module connected When the Install wizard detects that a new switch is connected to a to a new switch Matrix Module, a message informs that you must decide how to man-

age the switch.

If you want to manage it separately, the installation is completed and the switch is displayed in the Intel Device View window. If you want to manage it as part of a stack, you have the opportunity to assign consecutive IP addresses in the next dialog.

The Synchronization Wizard completes the installation. The complete stack, including the new switch, then appears in the Intel Device View window. The Synchronization wizard is described in detail in “Stack Synchronization Manager”, p. 95.

Managing an existing

The diagram above, shows two switches. On the left, we see the two switches connected and the ports are grouped in two VLANs: A and B. On the right, we have enabled STP; STP blocks the path between X and Z (to avoid looping) and, therefore, destroys the VLAN setup (because VLAN B needs these ports to receive messages).

The switch is delivered with Spanning Tree default values set to those recommended by the IEEE 802.1d standard. These values are conservative worst-case estimates for LANs consisting of a large number of switches. Therefore, changing these default values may improve the performance of your network.

4 Configuration

In this chapter

In this chapter you will learn how to use Advanced Configuration ef-

 

fectively. This chapter covers the Virtual LAN (VLAN) features.

 

You can create logical network groups (VLANs) by segmenting the

 

switch; for example, according to the subnetting scheme within your

 

network. Each VLAN is an isolated group and the switch only for-

 

wards traffic between members of the same group. Communication

 

between groups can be implemented using routers.

 

Note This switch is able to forward tagged frames from devices

 

supporting IEEE 802.1p/Q. These frames are only for-

 

warded to ports that are in the same VLAN.

 

However, IP policies cannot be used for devices using tagged VLANs

 

and IP learning is not possible.

 

 

VLANs (Virtual LANs)

Purpose

You can use VLANs to:

 

Create up to 128 separate user groups

 

Limit broadcast and multicast traffic

 

Increase security by limiting communication between groups

65

C H A P T E R 4 Advanced Configuration

Allocate network resources (such as servers) to groups

For a more comprehensive explanation of the VLAN concept, refer to the online help.

Warning when using STP

It is important to be aware of problems that may arise when using

 

Spanning Tree and VLANs. The Spanning Tree can use alternative

 

paths (such as different ports) to get messages to their destination.

 

VLANs specify which ports can receive messages (see “Spanning

 

Tree”, p. 55).

 

Warning When using the Spanning Tree facility, use only one

 

VLAN. If you use two or more VLANs, unexpected

 

changes in your network topology may occur.

Policy-based VLANs

The switch or stack uses “Policy-based VLANs”. This means that the

 

devices attached to the switch/stack can be grouped by any combina-

 

tion of MAC address, IP address, IP net and port number; therefore,

 

devices can belong to one or more VLANs.

Policy hierarchy

To avoid conflicts between two VLANs, a strict priority of the poli-

 

cies is used:

 

1. MAC address

 

2. IP address and IP net

 

3. Port

 

Warning This means that a station learned by a MAC rule is not

 

learned by an IP or Port rule, and a station learned by an

 

IP rule is not learned by a Port rule. Only stations that

 

are not learned by MAC or IP rules are learned by a

 

Port rule.

 

Note IP policies can be used only when IP learning is enabled on

 

the respective ports.

Description

Stand-alone

For single switches: there is no exchange of

 

information with VLANs on other switches;

 

each switch is its own domain

 

(STDALONE).

 

 

 

For switches in a stack: there is an exchange

 

of information using VLANs between the

 

switches in the stack; these switches are in

 

their own domain (STDALONE).

 

 

Distributed

A domain is a collection of switches and

 

can contain up to 128 VLANs. If you select

 

distributed, each switch will be able to com-

 

municate with all the others in this domain.
