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.

contents. The carton should contain the following items:
♦One dual-speed stackable hub
♦One AC power cord, suitable for your area’s electrical power
connections
♦One daisy-chain cable
♦Four rubber feet to be used for shock cushioning
♦Screws and two mounting brackets
♦This User’s Guide

Identifying External Components
This section identifies all the major external components of the
hub. Both the front and rear panels are shown, followed by a de-
scription of each panel feature. The indicator panel is described in
detail in the next chapter.
Front Panel
♦LED Indicator Panel
Refer to the next chapter, Understanding Indicators, for de-
tailed information about each of the hub’s LED indicators.
♦Twisted-Pair Ports
Use any of these ports to connect stations to the hub. The
ports are MDI-X ports, which means you can use ordinary
straight-through twisted-pair cable to connect the hub to PCs,
workstations, or servers through these ports. If you need to
connect to another device with MDI-X ports such as another
hub or an Ethernet switch, you should use a crossover cable, or

Unpacking and Setup 9
connect using the Uplink port (described below). For more in-
formation about crossover connection, see the Crossover Cables
section.
♦Uplink Ports
The Uplink port is an MDI port, which means you can connect
the hub (or hub stack) to another device with MDI-X ports us-
ing an ordinary straight-through cable, making a crossover
cable unnecessary.
In 32-port model, port 16 and the Uplink-1port, port 32 and
the Uplink-2 is really the same port, except that their pinouts
are different. Do not use both Port 16 and the Uplink-1
port, Port 32 and the Uplink-2 port at the same time.
In 24-port model, port 12 and the Uplink-1port, port 24 and
the Uplink-2 is really the same port, except that their pinouts
are different. Do not use both Port 12 and the Uplink-1
port, Port 24 and the Uplink-2 port at the same time.
In 16-port model, port 16 and the Uplink port, is really the
same port, except that their pinouts are different. Do not use
both Port 16 and the Uplink port at the same time.

Rear Panel
♦Module Slots
Used to install module options for 100BASE-FX connection.
♦Daisy-Chain IN Port
When cascading a set of stackable dual-speed hubs, this port
should be connected to the Daisy-Chain OUT port of the previ-
ous hub in the stack (usually placed immediately above it). A
cascade of four hubs can be created in this way. The first and
last hubs in the stack use only one of the daisy-chain ports,
while the others use both.
♦Daisy-Chain OUT Port
Works in conjunction with the Daisy-Chain IN Port (see
above). Connect this port to the Daisy-Chain IN Port of the
next hub in the stack (usually placed immediately below it), us-
ing the enclosed daisy-chain cable.
♦AC Power Connector
For the power cord.

Installing the Hub
Installation
The site where you install the hub stack may greatly affect its per-
formance. When installing, consider the following pointers:
♦Install the hub stack in a fairly cool and dry place. See Ap-
pendix B, Specifications, for the acceptable temperature and
humidity operating ranges.
♦Install the hub stack in a site free from strong electromag-
netic field generators (such as motors), vibration, dust, and
direct exposure to sunlight.
♦Leave at least 10cm of space at the front and rear of the hub
for ventilation.
♦Install the hub on a sturdy, level surface that can support
its weight, or in an EIA standard-size equipment rack. For
information on rack installation, see the next section, Rack
Mounting.
When installing the hub stack on a level surface, attach the rub-
ber feet to the bottom of each device. The rubber feet cushion the
hub and protect the hub case from scratching.
Rack Mounting
The hub can be mounted in an EIA standard-size, 19-inch rack,
which can be placed in a wiring closet with other equipment. At-
tach the mounting brackets at the hub’s front panel (one on each
side), and secure them with the provided screws.

Hub State Indicators
♦Power Indicator
This indicator lights green when the hub is receiving power;
otherwise, it is off.
♦Switch Activity
This indicator green when the switch circuit active and the in-
dicator blinking green when transfers signals between 10-Mbps
and 100-Mbps network segments.
♦10M Activity, 100M Activity
These indicators indicate data packet on the respective 10Mbps
Ethernet or 100Mbps Fast Ethernet segments will blink green.
♦10M Collision, 100M Collision
These indicators indicate data collisions on the respective
10Mbps Ethernet or 100Mbps Fast Ethernet segments of the
hub. (If several hubs are stacked or linked together, all of
them should detect and indicate the same collision, since colli-
sions span the entire network segment.) Whenever a collision
is detected, the respective COL indicator will briefly blink am-
ber.
100BASE-FX Module Indicators
The FX Link/Rx, indicate a good link to a module installed.

Understanding Indicators

Port State Indicators
There have provide state indicators for each of the twisted-pair
ports on the hub. Each port’s LED status indicators report the
port is working on 10Base-T mode or 100Base-TX mode, and indi-
cator for link or receive status.
The following describes each indicator and the meaning of each
condition:
♦10M Link/Rx
This indicator green when the port is connected to a 10Mbps
Ethernet station , If the station to which the hub is connected
is powered off, or if there is a problem with the link, the LED
will remain off. And the indicator blinking green when the data
will be received to all other connected ports.
♦100M Link/Rx
This indicator green when the port is connected to a 100Mbps
Fast Ethernet station , If the station to which the hub is con-
nected is powered off, or if there is a problem with the link, the
LED will remain off. And the indicator blinking green when
the data will be received to all other connected ports.
