INTRODUCTION

AOpen 10/100Mbps SOHO Hubs give users a simple,
cost effective and reliable solution that upgrades network
performance. With 10/100Mbps plug-and-play dual
speed ports equipped in its compact size, it is possible to
achieve the coexistence of 10Mbps and 100Mbps
devices in a single network now and step to 100Mbps
network in the future. Network expansion is made easy
with the uplink port, used for connecting to another
10/100Mbps hub, located on the front panel. Each port
supports NWAY function.

With its compact size, lightweight and sleek design, the
AOpen SOHO Hub can easily be placed on a desktop
and installed. Furthermore, it provides
Power/Collision/100M and Link/Activity LED indicators for
simplified management.

Features

Key features are:

• 5/8-port 10/100Mbps SOHO Hub

• Compatible with the IEEE 802.3 10BASE-T

Ethernet and IEEE 802.3u 100BASE-TX Fast
Ethernet industry standards.

• With built-in switch function, it automatically
transfers packets between 10Mbps and 100Mbps

3

connections.

• LED indicators for power, 10Mbps collision,
100Mbps collision, 10M Link/Activity, 100M
Link/Activity and expansion port full-duplex status.

• Bridge Uplink port for easy expansion, which
supports uplink distance up to 100 meters.

• External AC power adapter.

HARDWARE DESCRIPTION

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 Hub.

• LED Indicator Panel

Refer to the LED Indicator section for detailed

information about each of the hub’ s LED
indicators.

Rear Panel

AOH-605 5-port SOHO 10/100Mbps Fast Ethernet Hub

AOH-608 8-port SOHO 10/100Mbps Fast Ethernet Hub

• DC Power Jack: Power is supplied through an
external AC power adapter. Check the technical
specification section for information about the AC
power input voltage.

• MDI-X Jacks: Use these jacks to connect
stations to the hub. These are MDI-X (Medium­Dependent 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

6

using the MDI-II jack (described below).

• Uplink Jack(s) (MDI-II): Use this jack to connect
stations to the hub. This is MDI-II (Medium­dependent Interface, straight-wired) jack, which
means you can connect the hub to a device with a
MDI-X port using an ordinary straight-through
cable.

LED Indicators

AOH-605 5-port SOHO 10/100Mbps Fast Ethernet Hub

AOH-608 8-port SOHO 10/100Mbps Fast Ethernet Hub

• Power Indicator (PWR)

When this indicator lights green, the hub is receiving

power, otherwise. it is off.

• Expansion switch port full duplex status (EXP-
FDX)

7

When this indicator lights green, the expansion switch

port active on full-duplex mode.

• 100M Collision (COL 100M)

This indicator indicates there is data collisions on the

respective 100Mbps Fast Ethernet segments of the
hub. Whenever a collision is detected, this COL 100M
indicator will briefly blink amber.

• 10M Collision (COL 10M)

This indicator indicates data collisions on the

respective 10Mbps Ethernet segments of the hub.
Whenever a collision is detected, this COL 10M
indicator will briefly blink amber.

Note. Since collisions occur frequently on a network

with many nods, the LED flashes more rapidly as the
number of users or network traffic increases.

• 10M Link/Activity (Link/Act. 10M)

When this indicator lights green, the port is connected

to a 10Mbps Ethernet card or hub. When the LED is
blinking green, it indicates the data is
receiving/sending from the network and is processed
by the hub. If the LED does not light on, It means the
cable link is not established or the port is connected to
a 100Mbps Ethernet card or hub.

• 100M Link/Activity (Link/Act. 100M)

When this indicator lights green, the port is connected
to a 100Mbps Ethernet card or hub. When the LED is
blinking green, it indicates the data is

8

receiving/sending from the network and is processed
by the hub. If the LED does not light on, It means the
cable link is not established or the port is connected to
a 10Mbps Ethernet card or hub.

MAKING CONNECTIONS

This chapter discusses how to connect end nodes, and
uplink two hubs together.

Connecting to computers

After the hub is properly installed, it can support up to
five/eight computers.

1. Insert one end of the UTP (Unshielded Twisted Pair)
Category 5 cable into the RJ-45 connector that is
numbered from 1 to 8 of AOH-608 (or 1 to 5 of AOH-

605). Please orient the cable correctly and push it
into the connector until you hear a click.

2. Please make sure that the maximum length of the
cable from your computer to the hub does not exceed
100 meters.

3. After connecting to the hub, please check if the Link
LEDs on the adapter card and the hub (Link/Act) are
lit up.

10

Connecting to Hub or Switch

The hubs are only connected by uplink port

1. Plug on end of the UTP Category 5 Cable connector
into the Uplink port of the first hub.

2. Plug the other end into the ordinary port of the
second hub.

Note. Crossover cable is not necessary in establishing
uplink connection through uplink port.

It is important to know that the uplink port of AOpen
SOHO Hub with a SWITCH port. You can use this uplink
port connect two hubs together with maximum distance
up to 100 meters. It also support bridge function, which
provides scalable network expansion (unlimited
expandability!!)

APPENDIX A:RJ-45 PIN SPECIFICATION

When connecting your AOpen SOHO 10/100M NWay
Hub to another switch, a bridge or a hub, a modified
crossover cable is necessary. Please review these
products for matching cable pin assignment.
