(Optional) Connecting multiple hubs
Connecting hubs running at 100 Mbps to hubs running at 10 Mbps
Use an Intel Cascade Cable to connect the hubs. Hubs running at 100 Mbps can talk to each other,
and hubs running at 10 Mbps can talk to each other. However, hubs running at 100 Mbps can’t talk
to hubs running at 10 Mbps without bridging equipment. See pages 5-7 for more information.

Connection Guidelines
Connecting 100BASE-TX devices
• Use Category 5 twisted-pair Ethernet (CAT 5 TPE) cable.
• Always limit the distance between devices connected with TPE
cable to 100 meters (the IEEE specification requires this).
• Use a crossover cable to connect the hub to a switch. Use a
straight-through cable to connect the hub to a server or
workstation. See pages 12-13 for more information on cabling.
• Never connect two hubs operating at 100 Mbps with TPE cabling

Class I hubs). You must use an Intel Cascade Cable.
• Never connect a device to the hub at full-duplex. Only the
optional Ethernet Module or Fiber Module supports full-duplex.
Connecting 10BASE-T devices
• Use Category 3, 4, or 5 twisted-pair Ethernet (CAT 3, 4, or 5
TPE) cable.
• Use a crossover cable to connect a hub to another hub or a switch.
Use a straight-through cable to connect a hub to a server or
workstation. See pages 12-13 for more information on cabling.
• Follow the 5-4-3-2-1 general rule when daisy-chaining 10 Mbps
hubs. See page 9 for more information.
• Always limit the distance between devices connected with TPE
Power
cable to 100 meters (the IEEE specification requires this).
• Use an Intel Cascade Cable to connect hubs when:
- you want all hubs in the stack to count as a single repeater.
- you want to use a single Management Module to manage all
hubs in the stack.
• Never connect a device to the hub at full-duplex. Only the
optional Ethernet Module or Fiber Module supports full-duplex.

NOTE
You must use an Intel Cascade
Cable to connect hubs running
at 100 Mbps. Do not daisychain hubs with TPE crossover
cabling.
Intel Cascade Cable
(product code EE110CC)
NOTE
In a managed stack of hubs,
the optional Management Module can communicate with all
hubs, regardless of speed.
Example Configurations
Mixed 10 Mbps and 100 Mbps environment
A stack of Express 10/100 Stackable Hubs can contain hubs running
at both 10 and 100 Mbps. However, the hubs running at 10 Mbps and
the hubs running at 100 Mbps are on separate network segments.
These two segments can’t communicate with each other unless you
use another device to bridge them.
There are several ways to bridge the 10 Mbps and 100 Mbps
segments:
• Use the optional Intel Express Stackable Hub Ethernet Module
(product code EE110EM).
• Use a switch capable of both 10 Mbps and 100 Mbps operation,
such as the Intel Express 10/100 Fast Ethernet Switch (product
code ES101TX).
• Use a server with two 10/100 adapters installed.
• Use the Intel Express 10/100 Downlink (product code EC100DL).
• Use a router capable of both 10 Mbps and 100 Mbps operation
(not described here).
The Ethernet Module acts
as a switch port plugged
into a hub. It has the added
benefit of connecting to a
switch or server configured
at full-duplex.
This is the only time you can
connect an Express 10/100
Stackable Hub to a device
at full-duplex.
Bridging with the Intel Express Stackable Hub
Ethernet Module (sold separately)
The Ethernet Module plugs into the expansion slot of a 12-port hub
running at either 10 Mbps or 100 Mbps. Simply plug the module into
a hub running at one speed and connect to a hub running at the other
speed, and the Ethernet Module bridges the two collision domains.

If you plug the Ethernet Module
into a hub running at 100 Mbps,
connect it to a hub running at
10 Mbps with CAT 3, 4, or 5
TPE.
If you plug the Ethernet Module
into a hub running at 10 Mbps,
connect it to a hub running at
100 Mbps with CAT 5 TPE.

The benefits of the switch
are its port density (eight
base ports expandable to
12), performance, and
manageability.
Bridging with the Express 10/100 Fast Ethernet
Switch
A switch with individual ports capable of operating at 10 or 100 Mbps
can bridge 10 Mbps and 100 Mbps segments. No configuration of
your network operating system is needed.
Hubs 1 and 2 are in one
collision domain and share
100 Mbps of bandwidth.
Hubs 3 and 4 are in a
separate collision domain
from 1 and 2 and share 10
Mbps of bandwidth.
The server handles the
bridging and allows hubs
1 and 2 to talk to hubs
3 and 4.

Bridging with a server equipped with two 10/100
adapters (requires NOS that supports multiprotocol routing)
If you’re using a NOS that supports multi-protocol routing, such as
Novell NetWare* or Windows NT*, an inexpensive way to bridge the
10 Mbps and 100 Mbps segments is to install two 10/100 adapters
(one running at 10 Mbps and the other at 100 Mbps) in your server
and let the server bridge the segments.
Check with your NOS manufacturer to verify support for multiprotocol routing.

Here, the 2-port 10/100
Downlink bridges the two
100 Mbps hubs to the two
10 Mbps hubs.
The benefits of using the
Downlink are its low cost
and simplicity. Just plug the
hubs into the Downlink; it
takes care of the rest.
Bridging with the Express 10/100 Downlink
The Express 10/100 Downlink has two ports that operate at either 10
or 100 Mbps. Each port automatically senses the speed of the attached
device. All you need to do is set the speed of the hubs. No
configuration of your network operating system is needed.

100 Mbps-only environment
In the 100-Mbps only environment, you can only connect hubs using
an Intel Cascade Cable. You must also use CAT 5 TPE cabling to
connect devices (switches, workstations, servers, and so on). The
distance between a port and an attached device can’t exceed
100 meters.

Extending the 100 Mbps network topology
You can extend the network topology only by connecting hubs to a
switch, bridge, or router. You can’t extend the topology by daisychaining hubs together. In the example below, the network diameter is
extended to 400 meters by connecting the two hub stacks to an Intel
Express 10/100 Fast Ethernet Switch. Each stack is a separate
collision domain.

Extending the 10 Mbps network topology
To extend the 10BASE-T network topology, you can attach hubs to a
switch or daisy-chain the hubs using TPE cabling.
If you attach a stack of hubs to a switch, each stack gets its own
10 Mbps of bandwidth.
Attaching hubs to a switch
The illustration below shows two stacks of Express 10/100 Stackable
Hubs operating at 10 Mbps attached to Intel Express 10/100 Switch
ports also operating at 10 Mbps. Each TPE cable is extended to 100
meters, from workstation to hub and hub to switch. The total network
topology is extended to 400 meters.

Hub-to-hub TPE connections should not exceed 100 meters, and no
more than five hubs can be connected (a stack of hubs counts as one

Understanding LEDs
NOTE
If you don’t see the Green LED
light immediately, wait. Establishing a link to a device can
take up to six seconds.

Green Solid Port has a link.
Blinking Receive activity detected on port.
Off No link detected.
Amber Solid Port is disabled by management (not applicable
Steady blink and Status LED Hub speed and device speed don’t match.

Partitioned ports
A port is automatically disabled by the hub when a serious error
occurs, such as a series of more than 64 collisions on a single packet.
Once the hub sees a valid packet from the device or is able to transmit
a packet from the port, the hub automatically unpartitions the port.
Connected devices are usually not affected by a partitioned port
because the port is unpartitioned so quickly.
Usually a partitioned port signals an overloaded network or a
malfunctioning device on the network. Alleviate an overloaded
network by segmenting the network so that fewer devices share a
fixed amount of bandwidth. Do this by adding a switch.
NOTE
If you change the speed, the
hub keeps the setting until you
change it again, even if you
turn off the hub’s power.
Changes the hub
speed. The default
speed is 100 Mbps.
Unit LEDs
Unit LEDs indicate the status of a hub’s power supply, hub speed,
collision occurrences in a hub or stack of hubs, and whether a hub is

Cabling Requirements
Incorrect cabling is often the cause of network problems. Read the
next two pages if you’re unsure of your requirements.
100BASE-TX requirements
The 100BASE-TX Fast Ethernet specification requires you use
CAT 5 unshielded twisted-pair (UTP) or shielded twisted-pair (STP)
cabling to operate at 100 Mbps (UTP and STP are collectively
referred to as TPE). If you use lower grade cabling (CAT 3 or CAT 4
TPE), you may get a connection, but will soon experience data loss or
slow performance.
You’re limited to 100 meters between any two devices (the IEEE
specification requires this).
10BASE-T requirements
The 10BASE-T Ethernet specification allows you to use CAT 3,
CAT 4, or CAT 5 unshielded twisted-pair (UTP) or shielded twistedpair (STP) cabling to operate at 10 Mbps (UTP and STP are
collectively referred to as TPE).
12
You’re limited to 100 meters between any two devices (the IEEE
specification requires this).
100BASE-FX requirements
The optional Fiber Module (Intel product code EE110FX) lets you use
multimode fiber optic cable to connect to a switch, bridge, or router
up to 160 meters away at half-duplex. With a full-duplex connection,
you can connect up to 2 km away. Using the Fiber Module or the
Ethernet Module are the only cases in which you can establish a fullduplex link to the hub.
The module uses an SC fiber optic connector.

Straight-through vs. crossover cables
Ports on the hub are wired MDI-X (media dependent interface
crossover) so you can use a straight-through cable when connecting to
a workstation or server (network adapter cards are wired MDI). For
direct connection to another MDI-X port (hub and switch ports), you
must use a crossover cable.
SCHEMATICS FOR STRAIGHT & CROSSOVER TWISTED-PAIR
CABLE
Straight-Through Crossover
Hub Adapter Hub Hub/Switch
1 RX + 1 TX + 1 RX + 1 RX+
2 RX - 2 TX - 2 RX - 2 RX -
3 TX + 3 RX + 3 TX + 3 TX +
6 TX- 6 RX - 6 TX- 6 TX -
Determining which cable to use
NOTE
TPE crossover cables can be
used only to daisy-chain hubs
running at 10 Mbps.
You can’t use TPE crossover
cables to daisy-chain hubs running at 100 Mbps. You must
use an Intel Cascade Cable.
The following guidelines are based on the Express 10/100 Stackable
Hub, the Intel 10/100 Fast Ethernet Switch, the Intel EtherExpress™
family of network adapters (server or workstation), and the
NetportExpress™ family of print servers. These guidelines apply
to the majority of hubs and switches and all servers, workstations,
or print servers.
For this connection Use this cable
Hub to switch Crossover
Hub to hub (10 Mbps only) Crossover
Hub to server or workstation Straight-through
Hub to print server Straight-through
13
Troubleshooting
No link (green LED is off).
• Remove the cable and plug it in again. Wait up to six seconds for
a link.
• If you’re using the wrong type of cable, either straight-through or
crossover, the green LED above the port will not come on. Use
the other type of cable.
• Make sure the device you’ve connected to a port is a 10BASE-T
or 100BASE-TX device. The Express 10/100 Stackable Hub
doesn’t support 100BASE-T4 devices running at 100 Mbps.
However, it does support T4 devices running at 10 Mbps.
No link, amber LED above port is blinking slowly.
The hub speed setting doesn’t match the attached device’s speed
setting. To correct the problem, change either the hub or device speed
setting so they match. Remember, all hub ports operate at the same
speed. You can’t connect both 10BASE-T and 100BASE-TX devices
to the same hub.
Link, but amber LED above port is blinking erratically.
The port was partitioned (auto-disabled). This condition is usually
caused by a malfunctioning network adapter, bad cable, or an
overloaded network segment. See page 10 for more information.
14
Intermittent loss of link.
• If hubs are operating in a 100 Mbps environment, make sure you
use an Intel Cascade Cable to connect the hubs. You can use TPE
cabling only when connecting hubs running at 10 Mbps.
• Make sure the device connected to the hub port is configured for
half duplex operation. Hubs operate at half duplex only.
• A cable segment somewhere in your collision domain is too long.
Make sure none of your TPE cabling is longer than 100 meters.
• Make sure your stack of hubs contains no more than eight hubs.
• You may be using the wrong grade of cable. If you are, you will
experience intermittent performance and you may eventually lose
the connection between the port and the attached device. For more
information, see page 12.
Frequently Asked Questions
I have 10 Mbps and 100 Mbps hubs connected with an Intel
Cascade Cable. Can they talk to each other?
No. All hubs running at 100 Mbps are in one collision domain (or
segment) and all hubs running at 10 Mbps are in a separate collision
domain. See pages 5-7 for bridging options.
Then why would I connect hubs running at 10 Mbps to hubs
running at 100 Mbps?
For management purposes. By connecting hubs running at 10 and 100
Mbps in the same stack, you need only one Management Module to
manage the entire stack. This simplifies the network management
configuration.
Remember to connect the hubs with an Intel Cascade Cable, not TPE
cabling.
How do I get hubs running at 10 Mbps to talk to hubs running at
100 Mbps?
See pages 5-7 for bridging options.
Can I set the speed on individual ports?
No. All ports on a hub run either at 10 Mbps or 100 Mbps.
I need to connect the hub to a device that’s farther than 100
meters away. What do I do?
100 Mbps devices: Purchase an optional Fiber Module (Intel product
code EE110FX). This allows you to extend the distance between the
hub and device to a maximum of 160 meters at half-duplex or 2 km at
full-duplex. The module plugs into the 12-port hub running at either
10 or 100 Mbps. See page 12 for more information.
Also, you can purchase a switch or bridge. This allows you to extend
the distance between any two devices to 200 meters (100 meters from
the switch or bridge to the hub and another 100 meters from the hub
to the device).
10 Mbps devices: See the above 100 Mbps device options.
Additionally, you can daisy-chain hubs running at 10 Mbps with TPE
cable. See page 9 for more information.
15
Can I configure a full-duplex link between the hub and another
device?
Only to the optional Ethernet Module or Fiber Module. The external
ports on the modules are switched ports and are capable of full
duplex. The base ports of the hubs aren’t capable of full-duplex
operation.
Can I connect a 100BASE-T4 device to the hub?
If the device is capable of 10 or 100 Mbps operation, you can connect
it at 10 Mbps. You need to purchase a 100BASE-T4 hub to connect a
100BASE-T4 device at 100 Mbps.
Can I daisy-chain hubs together with TPE cabling?
Only hubs running at 10 Mbps. You must use an Intel Cascade Cable
to connect hubs running at 100 Mbps.
If I daisy-chain hubs running at 10 Mbps, can I use one network
management module to manage all connected hubs?
No. You can manage only multiple hubs connected with an Intel
Cascade Cable.
Can I stack Intel Express 10/100 Stackable Hubs with Intel
Express 100BASE-TX Stackable Hubs?
16
No. The hubs use a different Cascade Cable and connectors. However,
both are 100BASE-TX compliant and can easily exist in the same
network. To connect the hubs, use an optional Ethernet Module, Intel
Express 10/100 Fast Ethernet Switch, or Express 10/100 Downlink.
