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 1M 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...
Workstation or server Straight-through cable 1:1 Device with MDI-X ports (for exam-
Crossover cable
ple another Intel switch or hub) Device with MDI ports S traight-throug h cable 1:1

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.
11
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.
12
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.
13
C H A P T E R 1 Intel Express 520T Switch
LED Indicates
Default se ttin gs afte r st art­up
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.
14
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:

20
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.
21
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.

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.

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
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 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.

Changing VLAN mode
To change the mode of operation of a VLAN:
1 Select VLAN Setup. 2 Click Advanced. The VLAN mode is shown.
3 Click the VLAN mode to see the full range of choices.
VLAN Mode Description
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.
4 Click the new mode and make sure the rest of the details are
correct.
5 Click OK.
Your switch may turn blue (for a few seconds) while the net­work stability return s; this is normal.

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.
