Quick Start
1. Turn off the power, then unscrew and remove the panel from an expansion slot on
the Express 10/100 Stackable Hub.
Expansion slots: Use either slot. They are
identical.
Turn off the power before installing.

get a link, try the other port.
The LEDs light for both ports, even
though you can use only one port at
a time. This is normal.

Overview
This guide covers the Intel Express Stackable Hub Ethernet Module (product code EE110EM) and the
Intel Express Stackable Hub Fiber Module (product code EE110FX). The Ethernet Module supports
both the 10BASE-T Ethernet and 100BASE-TX Fast Ethernet standards. The Fiber Module supports
the 100BASE-FX Fast Ethernet standard.
The modules can be used only with the 12-port version of the 10/100 Stackable Hub (product code
EE110TX12). You can install either module in a hub running at 10 or 100 Mbps.

Ethernet Module
The Ethernet Module acts as a switch port plugged into an Express
10/100 Stackable Hub. The Ethernet Module
• bridges Express 10/100 Stackable Hubs running at 10 Mbps to
• connects Express10/100 Stackable Hubs running at 100 Mbps
• connects an Express10/100 Stackable Hub to another device at
Bridging 10 and 100 Mbps hubs
To bridge hubs of different speeds, simply plug an Ethernet Module
into an expansion slot on a 12-port hub (see “Quick Start” on page 1),
then connect to a hub running at the other speed. The Ethernet Module
bridges the two collision domains.

This Ethernet Module is plugged into a hub running at 10 Mbps. The
module is then connected to a 100 Mbps hub using CAT 5 TPE cable
only.
Notes on bridging
1 You can insert the Ethernet Module into a hub running at 10 or
100 Mbps.
2 You don’t need to configure the speed or duplex mode.
3 Do not change the duplex mode to full-duplex.
4 If you’re using a straight-through TPE cable (standard cable), use
the MDI port on the Ethernet Module.
5
Connecting 100 Mbps hubs with TPE cable
Class I hubs, such as the Intel Express 10/100 Stackable Hub, cannot
be directly connected with TPE cable when running at 100 Mbps.
However, since the Ethernet Module acts as a switched port on a hub,
you can use it to connect to another 100 Mbps hub with TPE cable.
Each hub or hub stack is a separate collision domain.
NOTE
Using an Ethernet Module is
the only way you can connect
Express 10/100 Stackable
Hubs to each other with TPE
cable while operating at 100
Mbps.

Category 5 TPE (100 meters max.)
Because you’re connecting to a hub port, you cannot establish a fullduplex connection between the hubs.
You don’t need to configure the speed or duplex mode of the Ethernet
Module. Auto-negotiation will work for both settings.
Notes on connecting hubs running at 100 Mbps
1 Use only Intel Cascade Cable (product code EE110CC) to stack
hubs.
2 Never connect hubs operating at 100 Mbps with TPE cable unless
you use an Ethernet Module.
3 No configuration of the speed or duplex mode is needed.
4 Do not change the duplex mode to full-duplex.
