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

Introduction

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.

Unpacking and Setup

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

MDI-II (Medium-dependent Interface, straight-wired)
