Quick Start
1. Install the Express 10/100 Stackable Hub in a rack or on a shelf or table,
plug it in, and turn the power on.
2. Connect either 100BASE-TX devices or 10BASE-T devices to the ports.
3. Check the LEDs for links. You’re done.
Next steps (Optional)
Continue to the next page if you want to connect multiple hubs.
Rack:Use the four small screws to attach
the brackets to the hub. Use the four large
screws (not shown) to attach the hub to
the rack.

(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.
Connecting hubs running at 100 Mbps
Use an Intel Cascade Cable to connect the hubs. You can connect a maximum of eight hubs. See
page 4 for more information.
Connecting hubs running at 10 Mbps
Use an Intel Cascade Cable to stack the hubs or daisy-chain the hubs with TPE cable. All hubs in a
stack share 10 Mbps of bandwidth and count as one repeater hop. Hubs connected with TPE cable
count as two repeater hops. See page 4 for more information.
or
Never connect hubs running at 100 Mbps
with TPE cable. Doing so violates the IEEE
802.3u Fast Ethernet standard for Class I
hubs.
Connect hubs with CAT 3, 4, or 5 TPE cable.
Limitdistanceto100meters.
Hubs 1 and 2 are in one collision domain and
share 100 Mbps of bandwidth.

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
(this violates the IEEE 802.3u Fast Ethernet specification for
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
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
TheacronymTPE(twisted-pair
Ethernet) refers to Category 3,
4, or 5 unshielded twisted-pair
(UTP) cabling or Category 5
shielded twisted-pair (STP)
cabling.

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).
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.

Intel Cascade Cable
(product code EE110CC)
NOTE
You must use an Intel Cascade
Cable to connect hubs running
at 100 Mbps. Do not daisy-

cabling.
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 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.

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.

Bridging with a server equipped with two 10/100
adapters (requires NOS that supports multi-
protocol 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 multi-
protocol routing.

The benefits of the switch
are its port density (eight
base ports expandable to
12), performance, and
manageability.
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.

7
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.

Configure
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.

100 Mbps
shared among
all hubs in
stack
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.
Ifyouintendtoinstallanoptional
Management Module in a
12-port hub, place the hub at
eye level. This makes it easier
toreadthemodule’sLCDpanel.

8
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 daisy-
chaining 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.
