1 Setting up the Intel®
Express 530T Switch
Overview
This guide provides information on configuring and managing the Intel®
Express 530T 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 such as link aggregation and Virtual LANs (VLANs)
•Chapter 3 - How to use Intel Device View
•Chapter 4 - How to use Web Device Manager
•Chapter 5 - Overview of Local Management
Management
Through the switch’s built-in management you can configure the device
and monitor network health. Thereare several methods for managing this
switch; you can use one method or any combination.
•SNMP management applications such as Intel®Device View,
LANDesk®Network Manager, or HP 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; Local Management is a menu-driven interface.
•Other SNMP-compliant applications can manage 530T switches
if you compile the switch’s MIB files into that application.

Media Requirements
Incorrect cabling is often the cause of network performance problems.
Read the next two pages to make sure your cabling is correct.
10Base-T
The 10Base-T Ethernet specification allows you to use CAT 3, CAT 4,
or CAT 5 UTP cabling. The limit is 100 meters between anytwo devices.
100Base-TX
The 100Base-TX Fast Ethernet specification requires that you use CAT
5 UTP cabling to operate at 100Mbps. If you use lower grade cabling
(CAT 3 or CAT 4) you may get a connection, but also experience data
loss or slow performance. You’re limited to 100 meters between any two
devices.
1000Base-T
The 1000Base-T Gigabit specification requires that you use CAT 5 UTP
cabling to operate at 1000Mbps. If you use alower 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 -LX Gigabit Modules provide a high-
speed connection to another device up to 5 km away. 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.
Selecting the right cable
NOTE
100 meters = 328 feet
200 meters = 656 feet
500 meters = 1640 feet
2 km = 2000 meters = 6560 feet

Straight-through vs. Crossover
Cable
Switch ports are wired MDI-X, so 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. Here are the pin
arrangements for the switch’s Ethernet port and the typical RJ-45
connector.

Stacking
The530T switch canbestacked with upto three 535Tswitches.Stacking
allows for a single point of management for all switches.
About a stack
•There can be only one 530T switch in a stack.
•The 530T switch requires the installation of a Stack Matrix Module
to stack it with a 535T. (Only one Stack Matrix Module is needed for
the entire stack.)
•The 530T can be stacked only with 535T switches.
•You can stack up to three 535T switches with a 530T.
•In a stack, the 530T is the control switch and the 535Ts are the
member switches.
•The member switches are all managed through the control switch’s
management interface.
•There is only one IP address for the entire stack of switches (the
control switch’s IP address).
•There can be only one instance of Spanning Tree, regardless of the
number of switches in the stack.
•Ports from any switch can be members of any VLAN.
•For link aggregation, the anchor ports are 1, 7, 15 for both the
control and member switches. You can also link aggregate the
module ports on the control switch (530T).
•You can only link aggregate ports on the same switch.

Assemble a stack
To stack a 530T with 535Ts, you need to purchase a Stack Matrix
Module.
1Insert the Stack Matrix Module into the slot in the back of the 530T,
labeled Matrix Module, and tighten the screws.
2Run a cable from the slot in the back of the 535T, labeled Stack
Interface Module, to the control switch’s Stack Matrix Module,
where it reads “Switch 1.”This connection makes this 535T switch
Member 2 in the stack.
3Repeat step 2 until you have added all member switches (535Ts) to
the stack. You can add a total of three member switches.
4Power on the control switch.
Which switch is which in a stack
In a stack of switches, the 530T is the control switch and the 535Ts are
member switches.
The switch that you connect to the port labeled Switch 1 in the 530T’s
Stack Matrix Module is referred to in the Web Device Manager and
Local Management as Member 2. The switch connected to the port
labeled Switch 2, is Member 3. And the switch connected to the port

NOTE
When setting up a stack, stack
the 535T switches in the order in
which they are connected to the
Matrix Module.
The 535T connected to the
Switch 1 port of the Matrix
Module would be the switch
directly under the control switch,
the 535T connected to the Switch
2 port would be underneath that,
etc.
This makes it easier to determine
which switch is which when
managing them.

What is a Switch?
A switch segments traffic, providing each port its own collision domain.
This is different than a hub where all ports belong to the same collision
domain.
Segments and hubs
Hubs combine multiple wires so all attached devices behave as though
they are on the same wire. Since thedevices 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.
The disadvantage is all devices must share the total available bandwidth.
The more devices that are attached to the hub results in less bandwidth
for each user. Also, network performance suffers since all devices
receive traffic and collisions from other users because the hub
retransmits data across all ports.
Switches
Switches send traffic only to specific ports, rather than transmit 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.
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 looks in 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 530T
Sample Configurations
The following examples illustrate how the 530T switch can be used in a
network.
The example below shows how a stack of 530/535 switches connects
with a stack of 550/510 switches (they cannot be in the same stack). This
example also demonstrates the 530T’s gigabit uplink by connecting it to
a 470F switch.

Flow Control
During times of heavy network activity, the switch’s port buffers can
receive too much traffic and fill up faster than the switch can send the
information. In cases like this, the switch tells the transmitting device to
wait so the information in the buffer can be sent. This traffic control
mechanism is called flow control.
The method of flow control depends on whether the port is set to full- or
half-duplex. If a port is operating 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 Express 530T switch.
Spanning Tree Protocol
Spanning Tree helps to prevent any 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 theconnection with the lowestcost and blocks
the second connection from working.
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 which can take
over in the event the primary link fails.
The 530T supports one instance of Spanning Tree per switch (or per
stack of switches).
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, traffic is sent over the
backup path automatically.

Cost: 100
Path: 2
