0 ABOUT THIS GUIDE
This guide discusses how to install and use your Ethernet/Fast
Ethernet dual-speed stackable hub.
Conventions
As used in this guide, the term hub, unless otherwise noted, refers
to the eight- or sixteen-port Ethernet/Fast Ethernet dual-speed
stackable hub with which this guide was packaged, or to another
hub in the same product family.
Overview of the User’s Guide
♦ Chapter 1, Introduction. Provides information on Fast
Ethernet networks and introduces your hub’s features.
♦ Chapter 2, Unpacking and Setup. Helps you get started in
setting up the hub.
♦ Chapter 3, Understanding Indicators. Describes all LED
indicators on the hub’s front panel. Understanding these
indicators is essential to effectively using the hub.

1 INTRODUCTION
This chapter introduces your hub and gives some background
information about the technology the hub uses.
Product Description
Your Ethernet/Fast Ethernet dual-speed stackable hub is designed
to allow easy integration and migration between 10-Mbps
Ethernet and 100-Mbps Fast Ethernet.
The hub can operate with both IEEE 802.3 10BASE-T connections
(twisted-pair Ethernet operating at 10 megabits per second) and
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 your hub (or to a stack of hubs in the same product
family) without any rewiring required when a host is upgraded
from 10 Mbps to 100 Mbps.
Hubs in this family can be purchased with or without a built-in
switching circuit to allow communication between network end
nodes operating at different speeds. If your hub has a SW Enable
indicator on its front panel, it has such a switching circuit. On a

hub that does not have such a switching circuit, only end nodes
operating at the same speed (10 or 100 Mbps) can communicate
with each other (unless the hub is stacked with a hub that does
have such a switching circuit—see below).
Your hub has eight or sixteen twisted-pair ports and can be
stacked together with other hubs in the same product family to a
maximum of five hubs in a stack. A stack of five sixteen-port hubs
gives a total of eighty Ethernet or Fast Ethernet ports. (Stacking
is also referred to as daisy-chaining).
As long as a stack contains at least one hub with a built-in
switching circuit, 10-Mbps Ethernet nodes will be able to
communicate with 100-Mbps Fast Ethernet nodes and vice versa,
regardless of which hub in the stack any node is attached to. Note
that if two or more hubs in a stack have switching circuits built in,
only one hub’s switching circuit will be enabled; any other
switching circuits in the stack will automatically be disabled, and
only one hub’s SW Enable indicator will shine. This is to allow
intercommunication without the danger of a signal loop forming.
Because it conforms to the standards for both Ethernet and Class
II Fast Ethernet repeaters, your hub (or a stack of hubs in the
same product family) can also be “uplinked” together with a
similarly conformant hub or hub stack to expand the network still
further. The uplink connection will carry both 10- and 100-Mbps
network signals.
