0 ABOUT THIS GUIDE
This guide discusses how to install and use your DHD-801/
DHD-1601, the 8/16-port 10/100Mbps Dual speed Hub.
Conventions
As used in this guide, the term hub, unless otherwise
noted, refers to the DHD-801 or DHD-1601, the dual speed
hub.

Introduction

1 INTRODUCTION
This chapter introduces your hub and gives some
background information about the technology of the hub
uses.
Product Description
DHD-801/1601 is designed to allow easy integration and
migration between 10Mbps Ethernet and 100Mbps Fast
Ethernet.
The hub can operate with both IEEE 802.3 10BASE-T
connections and IEEE 802.3u 100BASE-TX connections.
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
without any rewiring required when a host is upgraded
from 10 Mbps to 100 Mbps.
This Hub with built-in switch function allows
communication between network end nodes operating at
different speeds.
Because it conforms to the standards for both Ethernet and
Fast Ethernet Class II repeaters, your hub can also be
“Uplinked”together with a similarly conformant hub to

expand the network still further. The uplink connection
will carry both 10Mbps and 100Mbps network signals.
Product Features
The list below highlights your hub’s features and
specifications:
♦Compatible with the IEEE 802.3 10BASE-T Ethernet
and 802.3u 100BASE-TX Fast Ethernet industry
standards for interoperability with other Ethernet
and 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 diameter of 205 meters.
♦Eight/Sixteen 10/100Mbps NWay ports per hub for
connecting stations to the network.
♦Hubs with built-in switch function automatically
transfer packets between 10Mbps Ethernet and
100Mbps Fast Ethernet connections, allowing
communication between end nodes operating at
different speeds.
♦LED indicators for power, 10-Mbps collision (DHD-
1601), 100-Mbps collision, connection speed per port,
and port status per port.
♦Uplink jack for easy linking of two hubs to further
expands the network.
♦External AC power adapter.

2 UNPACKING AND
SETUP
This chapter provides information on the unpacking and
initial installation of your hub.
Unpacking
Open the shipping cartons of your hub and carefully
unpacks the contents. The carton should contain the
following items:
♦One 10/100Mbps Dual speed Hub
♦One AC power adapter, suitable for your area’s
electrical power connections
♦Accessory pack
♦This User’s Guide
If any item is damaged or missing, report the problem
immediately to your network equipment dealer.
Identifying External Compo-
nents
This section identifies all the major external components of
the hub. Both the front and rear panels are shown,

followed by a description of each panel feature. The
indicator panel is described in detail in the next chapter.
Front Panel
The figure below shows the front panels of the hubs.
8/16-port 10/100Mbps Dual speed Hub
♦LED Indicator Panel
Refer to the next chapter, Understanding Indicators, for
detailed information about each of the hub’s LED
indicators.
♦Port (MDI-X) Jacks
Use these jacks to connect stations to the hub. These are
numbered jacks, or called MDI-X (Medium-Dependent
Interface, Cross-wired) jacks, which mean, you can use
ordinary straight-through twisted-pair cables to connect
user machines and servers to the hub through them. If
you need to connect another device with an MDI-X jack,
such as another hub or an Ethernet switch, you should
use a crossover cable, or make the connection using the
MDI-X jack (described below). For more information
about crossover connections.
♦Uplink Jack (MDI-II)
Use this jack to connect another hub to the hub. This is
