This equipment has been tested and found to comply with the lim-
its for a Class A digital device, pursuant to Part 15 of the FCC
Rules. These limits are designed to provide reasonable protection
against harmful interference when the equipment is operated in a
commercial environment. This equipment generates, uses, and
can radiate radio frequency energy and, if not installed and used
in accordance with this user’s guide, may cause harmful interfer-
ence to radio communications. Operation of this equipment in a
residential area is likely to cause harmful interference in which
case the user will be required to correct the interference at his
own expense.

Conventions
References in this manual to the 16/24/32 port dual-speed stack-
able Ethernet/Fast Ethernet Hubs are frequently written simply
as “hub” or “hubs” where the text applies to all models. Model
names are normally used only to differentiate between models
where necessary.
Unless differentiated by model name, all information applies to all
models.

1 INTRODUCTION
This chapter introduces the 16/24/32 port dual-speed stackable
Ethernet/Fast Ethernet Hubs, as well as giving some background
information about the technology of the hubs use.
Product Description
The dual-speed stackable Ethernet/Fast Ethernet hubs described
in this manual are designed to allow easy migration and integra-
tion between 10Mbps Ethernet and 100Mbps Fast Ethernet, while
providing manageability and flexibility in cable connections.
These hubs can operate with either IEEE 802.3 10BASE-Tcon-
nections (twisted-pair Ethernet operating at 10 megabits per
second), or IEEE 802.3u 100BASE-TX connections (twisted-pair
Fast Ethernet operating at 100 megabits per second). All of the
twisted-pair ports support NWay auto-negotiation, allowing the
hub to automatically detect the speed of a network connection.
This means you can connect all of your Ethernet and Fast
Ethernet hosts to any hub in the series, without any rewiring re-
quired when a host is upgraded from 10Mbps to 100Mbps.
The hubs in the series, available in 16-port, 24-port and 32-port
models, can be stacked with up to four hubs in a stack. A stack of
four 32-port hubs gives a total of 128 Ethernet or Fast Ethernet

ports. An 16/24/32 port dual-speed stackable Ethernet/Fast
Ethernet Hubs stack operates as a Class II Fast Ethernet re-
peater, allowing it to be linked to another Class II Fast Ethernet
stack in the same collision domain.
In the basic configuration, the 10Mbps and 100Mbps segments are
separate but it can be intercommunicate. Because each unit has
built-in switch, so it can be intercommunicate and stacking up to
four units.
Add-in module is also available, providing 100BASE-FX connec-
tion. The hubs in this series each have one slot for slide-in
module.
Product Features
The list below highlights the features and specifications of hubs in
the series.
♦Compatible with the IEEE 802.3 10BASE-TEthernet and
802.3u 100BASE-TX, 100BASE-FX Fast Ethernet industry
standards for interoperability with other Ethernet/Fast
Ethernet network devices.
♦Ethernet connections support Category 3 or better twisted-
pair cables.
♦Fast Ethernet connections support both shielded twisted
pair and Category 5 unshielded twisted-pair cables.
♦Fast Ethernet connections support a maximum distance of
100 meters from end-station to hub, and a total network di-
ameter of 205 meters.
♦16, 24 or 32 NWay RJ-45 ports for connecting stations to the
network.
Introduction

♦Built-in switch allows bridging between 10Mbps and
100Mbps segments.
♦LED indicators for Power, FX Link/Rx, 100M Activity, 10M
Activity, 10M Collision, 100M Collision, Switch Activity,
10M Link/Rx, and 100M Link/Rx.
♦Two proprietary daisy-chain ports for cascading up to four
hubs to form one logical hub.
♦Uplink port allows easy linking of two Fast Ethernet hub
stacks to further expand your network.
♦Standard-size (19”, 1U height), rack mountable
♦Optional slide-in module: 100BASE-FX (see Chapter 4 :
Making Connections).
♦The total bandwidth of each stack is up to 140Mbps that
includes one 100Mbps segment and four 10Mbps segments.
(If per stack has stacking four units)
