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 inc hes) free space on both sides and behind the switch. Do not allow t he intake or outle t 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 tha t th e 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 IEC297 (or

similar); if th e minimum out side mea surements of the rack are 600 x 600mm (23.5 x 23.5inches), you must allow 190mm (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 (wit h side sup port rai ls). The ki t contains two mounting brackets and four screws (for attaching the brackets to the sides of the switch).

Tools required for positioning in a rack

In addition to the mounting kit, you need the following items to mount the switch in a rack:

• Standard 19-inch rack with side support rails.

• 3 mm screwdriver.

C H A P T E R 1 Intel Express 520T Switch

Installing a Module

Introduction You can increase the connecti vity options of your switch by installing

a module. Warning Modules are not designed to be installed in, or removed

from, the switch while it is in operation. You must power off the switch before attempting to install or remove a module.

Static-free working area The m odule’s printed circu it board is an Electrostatic Sensitive De-

vice and should be handled only in a static-free working area; otherwise, the printed circuit board may fail or be degraded.

Avoiding damage to the circuit board

If you remove the plate covering the slot on the front of the switch, for example, to install or remove a module, follow this procedure to avoid damage to your printed circuit board:

Warning Do not remove the plate unless the switch is discon-

nected from the main power supply.

1 Disconnect the switch from the main power supply. 2 Ground the switch before you handle the printed circuit board. 3 Connect yourself to a non-painted/non-isolated part of the

grounded switch (for example the back panel) using a wrist strap wi th 1MΩ resistance to ensure that you carry the same electrostatic charge as the enclosure.

4 Remove the plate covering the slot.

Installing a module To install a module:

1 If the switch is already operational, disconn ect it from th e main

power supply.

2 Follow the instructions in “Avoiding damage to the circuit

board” above.

3 Unscrew the screws of the plate covering the slot on the front of

the switch. Save these screws and plate.

4 Insert the module into the slot (following the instructions in the

module’s User Guide). Place your thumbs just beneath the screws on the front panel of the modul e and push in th e module. Secure it using the retaining screws.

C H A P T E R 1 Intel Express 520T Switch

Removing the module

To remove a module:

1 If the switch is already operational, disconnect it from the main

power supply.

2 Follow the instructions in “Avoiding damage to the circuit

board” above.

3 Unscrew the screws securing the module. 4 Pull the module gently to disengage the connectors fully from

the socket on the motherboard. Slide the module out completely.

5 Cover the empty module port with the plate and secure using

the screws.

Connecting Other Devices

Introduction Incorrect cabling is often the cause of network configuration prob-

lems

Use shielded cables Shielded cables normally comp ly with EMC and FCC emission lim-

its. Only use unshielded cables when it is explicitly specified in the in-

stallation manual of the device in question.

Cables for the LAN Ports Ports on the switch are wired MDI-X, so use the following cable:

If you connect the switch to a... Then use a...

C H A P T E R 1 Intel Express 520T Switch

RJ-45 connector pin assignments

Connecting a de vice to the RJ-45 ports

The RJ-45 ports on the front of the switch have the following pin assignments:

Pin number Function

1RX+ 2RX3TX+ 6TX-

To connect a workstation compatible with IEEE 802 .3 (Ethernet Version 1.0 and 2.0) or a fast access device (such as a server) to the

switch’s RJ-45 ports using UTP cable (Category 5):

1 Make sure that the device has a 100Mbps (100Base-FX or 10/

100Base-TX) network interface card installed. If not, use your network interface card’s documentation to

install and configure it c orrectly.

2 If your workstation is fitted with an RJ-45 interface then there i s

no problem. However, it is possible t o at ta ch t o ot her con nect or types using an appropriate adapter. For example, use a UTP/ 10Base-FL adapter for fiber connections

3 Connect one end of the UTP cable to an RJ-45 port on the

switch. According to IEEE 802.3, the cable le ngth must not exceed 100

meters (approximately 325 feet).

4 Connect the other end to the 100Base-TX connection on the

device.

Connecting the management PC

To manage the switch from a PC connected directly to the switch, the PC must not use frame tagging. To manage the switch from a PC with IEEE 802.1Q tagged frames, management must be through a device which untags the frames.

Cable fo r the C on sol e Port If you connect a PC (via th e Console Port), then use a null- modem ca-

ble.

C H A P T E R 1 Intel Express 520T Switch

Connecting the Power

Introduction After connecting the d evi ces to the switch, con nect th e power cabl e.

There are certain practical and safety considerations to be made before powering the switch on.

The Po w er Cable

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

in your countr y. If thi s is no t the case , conta ct your dealer immed iately and ask for the correct power cable.

Power cable wiring color code

The wires in the power cable provided are color coded:

Color Connection

Green and yellow Ground Blue Neutral Brown Live

Important for U K 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 an d the rack is con nected to a branch supply or a power supply socket with a ground connection.

To avoid overloadi ng the circui t and damagi ng the wiring of the power supply, the power supply to the rack must be adequ ate to c over the extra power consumed by the switch.

C H A P T E R 1 Intel Express 520T Switch

Power up

Powering up the switch Fo llow these steps to powe r up the switch:

1 Push the female end of the power cable into the main socket (i n

the rear panel); plug the other end into the power supply outlet.

2 Make 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 the re i s a fau lt within the switch and you must contact your dealer.

3 Verify 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:

Stage STATUS LED... Then the switch...

1 Is red Is starting up 2 Turns to steady green Has started successfully

If the Status LED remains red, then the switch has no t started successfully. Try to re start it; if the switch doe s not start, cont act your dealer.

Look at the other front panel LEDs during start-up and check that they are operating correctly.

Port LED s tates The LEDs reflect the state of each port:

LED Indicates

No lights Port enabled, no link. Green, blinking

randomly

Port enabled, RX/TX traffic, link pulse active.

Green, solid Port enabled, link pulse active.

C H A P T E R 1 Intel Express 520T Switch

Green and Orange both blinking r andomly

Collision detected (with half duplex).

Port enabled, link pulse active. Orange, solid Port disabled by management. Green and Orange both

solid

Port dis abled by a hardware fault, or no

hardware connected.

Once the switch has started successfully, installation is complete and the switch is using its default setti ng (al s o known as default confi guration):

• 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 t he swit ch’s address table (the MAC Add re ss Agi ng 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 confi guration is adequa te for simple wor kgroup environ-

ments to operate in basic switching mode. Although the switch continues to operate without problems, we rec-

ommend that you change cert ain parameters t o suit your own requ irements.

C H A P T E R 1 Intel Express 520T Switch

Follow the instructions in Chapter 2 to change the configuration while the switch is opera ting.

Other LEDs on the front panel

Introduction There are three other LEDs and one button on the front panel that

show how the switch is operating:

• Status LED

• Temperature LED

• Redundant Power Supply (RPS) LED

• Port Status button

LED colors and their meanings

The LEDs give information about the state of the switch:

Using Intel Device View

Concept Intel Device View configures all the parameters on your switch, or

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 Device View

The Intel Device View window

Basic menu bar commands

Many commands are available from within Intel Device View. These are best accessed using mouse actions. However, Windows users c an also access most of them through the menu bar.

There are three sections:

• 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

Before a switch or stack is contacted, the following commands are available through the menu bar. The toolbar buttons are for users using Intel Device View in Windows.

File menu This contains one command, Exit which enabl es you to exi t 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 permanent configurati on, yo u are asked i f you want to save th e new conf iguration 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 T r ee discover s

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.

C H A P T E R 2 Intel Device View

• A list of IP addresses — contains the last eight switches success-

fully contacted from Intel Device View. These can be used to manage the switch.

View menu — for Windows users only

The View menu allows you to customize the Intel Device View display to your own preferences: the Toolbar and Status Bar can be switched on and off.

Monitoring menu This menu gives access to set t he Default Preferences for Intel Device

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 swi tc h to an existing stack and then synchronize 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 tracing cables, as the ports on the Stack Interface Modules become the same color as the corresponding Matrix Module port.

• A color coding chart for Intel Device View to show the states of

switch’s LEDs

The diagram above, shows two switches. On th e l eft, we see the two switches connected and the por t s ar e grou ped i n t wo VLANs: A and B. On the right, we have enabled ST P; ST P blocks t he pat h bet ween X and Z (to avoid looping) and, theref ore, dest roys t he VLAN setup (because VLAN B needs these ports to receive messages).

Why change these from their defaults?

The switch is deli vered with Spanning Tr ee default values set to those recommended by the IEEE 8 02.1d 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 netw ork.

Advanced

In this chapter In this chapter you will le arn how to use Advanced Configura tion ef-

Configuration

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 su bnettin g scheme wit hin your network. Each VLAN is an isolated group and the switch only forwards traffic between members of the same group. Communication between groups can be implemented using routers.

Note This switch is able to forward tagged frame s from devices

supporting IEEE 802.1p/Q. These frames are only forwarded 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.

Purpose You can use VLANs to:

VLANs (Virtual LANs)

• Create up to 128 separate user groups

• Limit broadcast and multicast traffic

• Increase security by limiting communication between groups

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 swi tch or stack uses “Policy-based VLANs”. This means that the

devices attached to t he swit ch/s t ack can be grouped by any combi nation 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 VLAN s, a st ric t 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.

C H A P T E R 4 Advanced Configuration

Stand-alone For single switches: there is no exchange of

information with VLANs on other swi tches; each switch is its own domain (STDALONE).

For switches in a stack: there is an ex change 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 communicate with all the others in this dom ai n.

protocols and don’t want these stations to be learned using IP rules, you should:

1 Select VLAN Setup. 2 Click Advanced. 3 Click IP Traffic to specify which ports support IP learning.

Warning when using pruning

4 Click OK.

IGMP pruning

It is important to be aware of problems that may arise when using IGMP pruning and IP Multicast addresses.

Warning When using the IGMP pruning, IP multicast packets not

based on IGMP are discarded.

IGMP pruning can only be used in VLANs that have an IP link. Enabling IGMP pruning stops Layer 2 forwar di ng o f IP mul t ica st p ackets in all other VLANs without IP links.

Only enable IGMP pruning (on this device) when it is connected between the device receiving the packe ts and an IP multicast routing device. Or, disable IGMP pr uning (on t his device) when it is conn ected between the device t ransmi t ting t he pack ets an d a n IP mu lti cast rou ting device.
