Overview
This guide provides information on configuring and managing the Intel®
Express 460T Standalone Switch and is organized into these chapters:
•Chapter 1 - Information on the switch hardware and optional modules
•Chapter 2 - Information on using the switch in a LAN and advanced
features like link aggregation and virtual LANs (VLANs)
•Chapter 3 - How to use Intel Device View
•Chapter 4 - How to use Web Device Manager
•Chapter 5 - How to use Local Management
Management
Through the switch’s built-in management you can configure the device and
monitor network health. There are several methods for managing this
switch; you can use one method or any combination.
•SNMP management applications like Intel Device View, LANDesk®
Network Manager, or Hewlett Packard OpenView* are tailored for Intel
products and show a graphical representation of the device (with the use
of the proper MIB).
•Onboard management allows control over the device without using an
SNMP application. The Web Device Manager provides a graphical
interface while Local Management is a menu-driven interface.
•Other SNMP-compliant applications can manage 460T switches if
you compile the switch’s MIB files into that application.

When you are using the 1000SX, 1000LX, or 1000T module, only the port 1
LED will blink and show activity because the module has only one port.
Configuring Modules
Generally, you do not need to make any changes to the optional modules
because they are designed to configure themselves automatically for the
attached device. However, you might need to configure the modules in order
to communicate with older devices. You can use the Local Management or
Web Device Manager to configure the 100FX, 1000SX, 1000LX, or 1000T
modules. See Chapter 4 for more information about the Web Device
Manager, and Chapter 5 for more information about Local Management.

CHAPTER 1 Intel Express 460T Standalone Switch Users Guide
Media Requirements
Incorrect cabling is often the cause of network performance problems. The
next two pages provide information about how to make sure your cabling is
correct.
100Base-TX
The 100Base-TX Fast Ethernet specification requires that you use CAT 5
UTP cabling to operate at 100 Mbps. If you use lower-grade cabling (CAT 3
or CAT 4), you may get a connection, but also experience data loss or slow
performance. The limit is 100 meters between any two devices.
10Base-T
The 10Base-T Ethernet specification lets you use CAT 3, CAT 4, or
CAT 5 UTP cabling. The limit is 100 meters between any two devices.
100Base-FX
The optional Fiber Module lets you connect to a switch at distances up to
400 meters (hubs up to 160 m) at half-duplex or 2 km at full-duplex. Use
62.5/125 µm multimode fiber optic cable with an SC-type fiber optic
connector.
1000Base-T
The 1000Base-T Gigabit specification requires that you use CAT 5 UTP
cabling to operate at 1000 Mbps. If you use a lower grade cabling you will
experience either no connection or extreme data loss. The maximum
distance between any two devices is 100 meters.
1000Base-SX/1000Base-LX
The optional 1000Base-SX and 1000Base-LX Gigabit Modules provide a
high-speed connection to another device at distances up to 5 km. The
maximum distance depends on the type of cable used. Refer to the following
table for a list of cable types and maximum distances. Use cables with an
SC-type fiber optic connector.
NOTE:
100 meters = 330 feet
200 meters = 660 feet
500 meters = 1,650 feet
2 km = 2000 meters = 6,600 feet
5 km = 5000 meters = 16,500 feet

9/125 µm singlemode 5,000 m
Testing a Cable
When using a 100Base-TX module, you can quickly check the cable’s link
integrity by plugging one end into port 1 and the other end into port 2. Make
sure the crossover (MDI/MDI-X) button is out. Check the Activity LEDs for
ports 1 and 2. If the LEDs are on, you have a functioning crossover cable.
If the LEDs are off, push the MDI/MDI-X button in. If the Activity LEDs
for ports 1 and 2 turn on, you have a functioning straight-through cable.
However, if the LEDs remain off, you probably have a bad cable.
If a cable passes these tests, but the network connection is slow, verify that
wires 1, 2 and 3, 6 on the cable are twisted pairs, as shown in the following
diagrams.

CHAPTER 1 Intel Express 460T Standalone Switch Users Guide
Straight-through vs. Crossover Cables
Switch ports are wired for MDI-X. Use a straight-through cable to connect
to a workstation or server (network adapter cards are wired MDI). To
connect to another MDI-X port, use a crossover cable. Following are the pin
arrangements for the switch’s Ethernet port and the typical RJ-45 connector.

Overview
This section provides an overview for using the Express 460T standalone
switch within a network. The chapter covers the basic differences between a
switch and hub, basic switching features like flow control and Spanning
Tree, and a discussion of more advanced features such as link aggregation
and the types of VLANs available on the switch.
If you are already familiar with switching technology you can skip ahead to a
particular section within the chapter. The following list shows where you can

CHAPTER 2 Intel Express 460T Standalone Switch Users Guide
What is a Switch?
A switch segments traffic, providing each port its own collision domain. This
is different from a hub where all ports belong to the same collision domain.
Segments and Hubs
Hubs combine multiple wires so all attached devices behave like they are on
the same wire. Because the devices share the same segment, data sent by
one device is retransmitted to all devices on the same hub. This is equivalent
to having all devices connected in a bus topology as illustrated below.
Client A sends
signal to Client B
Client B
receives signal
Client A Client B
Signal sent to all ports
The disadvantage is all devices must share the total available bandwidth.
The more devices that are attached to the hub the less bandwidth for each
user. Also, network performance suffers because all devices receive traffic
and collisions from other users as the hub retransmits data across all ports.
Switches
Switches send traffic only to specific ports, rather than transmitting data
across all ports. This means that each device attached to the switch receives
fewer collisions and the entire bandwidth is available to the device.
Client A sends
signal to Client B
Client B
receives signal
The signal is not
sent to all ports
MAC Address Port
006011FB34DB 2
00A027D36FAA 8
The switch maintains a table that associates a device’s MAC address to a
port on the switch. When Client A communicates with Client B, the switch
checks the table to determine which port Client B is attached to and then
forwards the traffic to that port. If a device sends traffic to an address that is
not in the table (or sends broadcast or multicast traffic) the switch sends the
traffic out to all ports on the switch. When the switch receives a response it
updates the table with the new address.

Using the Intel Express 460T Standalone Switch CHAPTER 2
Using the 460T
Sample Configurations
The following examples illustrate how the 460T switch can be used in a
network.
Desktop PC Bandwidth
In this example, desktop PC users are connected directly to the 460T switch.
Power users are connected at 100 Mbps while regular users can be
connected at 10 Mbps. Aggregated links provide additional bandwidth to
the servers.

Small Office Backbone
In this example, the 460T switch serves as the backbone for a small network.
The switch can provide high-bandwidth support to the clients (servers and
power users) that require it while providing connections for 10 Mbps
devices. Use the optional modules available for the 460T to extend the reach
of the network beyond 100 meters (330 feet). For example, to connect
different buildings or remote campuses to an Intel®Express 550T Switch
located at a central office.
Two switches connected using 1000SX modules. The
maximum distance is 550m using multimode fiber.

CHAPTER 2 Intel Express 460T Standalone Switch Users Guide
Flow Control
When network traffic is heavy, the switch’s port buffers fill up faster than
the switch can send the information. In cases like this, the switch tells the
transmitting device to wait until the information in the buffer can be sent.
Thistraffic controlmechanismis calledflowcontrol.
The method of flow control depends on whether the port is set to full-duplex
or half-duplex. If a port operates at half-duplex, the switch sends a collision
(also called backpressure) which causes the transmitting device to wait. If
the port operates at full-duplex, the switch sends out an IEEE 802.3x PAUSE
frame. You can enable or disable flow control for each port on the 460T
switch.
Spanning Tree Protocol
Spanning Tree is a protocol that prevents loops within the network
topology. A loop can occur if there is more than one path for information to
travel between devices. The Spanning Tree Protocol works by determining
the “cost”of a connection. For example, if two devices are connected by two
links, Spanning Tree uses the connection with the lowest cost and blocks
the second connection.
Spanning Tree prevents loops by allowing only one active path between any
two network devices at a time. However, you can also use this behavior to
establish redundant links between devices that can take over if the primary
linkfails.

Switch A Switch C
Server BPC Client A
Switch B
In this example, Client A can communicate with Server B over two different
paths. The primary path is Path 1 because the cost of the connection
between switches A and C is lower than the cost between switches A, B and
C. If the primary path fails, then traffic is automatically sent over the backup
path.
Primary Path from Client A to Server B: Switch A –> Switch C
Backup Path from Client A to Server B:
Switch A –> Switch B –> Switch C
