INTRODUCTION

This chapter describes the features of this AOpen SOHO
Switch and some background information about
Ethernet/Fast Ethernet switching technology.

Fast Ethernet Technology

A number of high-speed LAN technologies have been
proposed to provide greater bandwidth and improve
client/server response times. Among them, 100BASE-T
(Fast Ethernet) provides a non-disruptive, smooth
evolution from the current 10BASE-T technology.
100Mbps Fast Ethernet is a new standard specified by
the IEEE 802.3 LAN committee. It is an extension of the
10Mbps Ethernet standard with the ability to transmit and
receive data at 100Mbps, while maintaining the
CSMA/CD Ethernet protocol. Since the 100Mbps Fast
Ethernet is compatible with all other 10Mbps Ethernet
environments, it provides a straightforward upgrade and
takes advantage of the existing investment in hardware,
software, and personnel training.

Switching Technology

Switching is a cost-effective way of increasing the total
network capacity available to users on a local area
network. A switch increases capacity and decreases
network loading by dividing a local area network into
different segments, which don’ t compete with each other
for network transmission capacity.

The switch acts as a high-speed selective bridge
between the individual segments. Without interfering
with any other segments, it automatically forwards traffic
that needs to go from one segment to another. By doing
this the total network capacity is multiplied, while still
maintaining the same network cabling and adapter cards.

For Fast Ethernet networks, a switch is an effective way
of eliminating problems of chaining hubs beyond the
“two-repeater limit.” A switch can be used to split parts of
the network into different collision domains, making it
possible to expand your Fast Ethernet network beyond
the 205-meter network diameter limit for 100BASE-TX
networks. Switches are also ideal for bridging between
the existing 10Mbps networks and the new 100Mbps
networks.

Today switches are an ideal solution to most kinds of
local area network congestion problems.

Features

AOpen SOHO Switch was designed for easy installation
and high performance in a SOHO environment where
traffic on the network and the number of users increases
continuously.

With its small, compact size was specifically designed for
small to middle workgroups. This AOpen SOHO Switch
can be installed where space is limited; moreover, they
provide immediate access to a rapidly growing network
through a wide range of user-reliable functions.

Key features are:

• Store and forward switching scheme capability.
As the result of complete frame checking and
error frame filtering, this scheme prevents error
packages from transmitting among segments.

• NWay Auto-negotiation for any port. This allows
for auto sensing of speed (10/100Mbps) thereby
providing you with automatic and flexible solutions
in your network connections.

• Flow control for any port. This minimizes dropped
packets by sending out collision signals when the
receiving buffer is full. Note that flow control is
only available in half-duplex mode.

• 1K MAC address entry table per device for AOW-605.
8K MAC address entry table per device for AOW-608.

• 1MB RAM buffer per device for AOW-605.
256KB RAM buffer per device for AOW-608.

• Compact desktop design great for SOHO
environment.

• External switching power supply for lower power
consumption and heat emission.

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.

Rear Panel

AOW-605 5-port SOHO 10/100Mbps Switch Hub

AOW-608 8-port SOHO 10/100Mbps Switch 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

using the MDI-X jack (described below). For more
information about crossover connections.

• 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, making a crossover cable unnecessary.

LED Indicators

• Power Indicator (PWR)

This indicator lights green when the hub is receiving

power, otherwise, it is off.

• Full-Duplex/Collision (Full-Duplex/Collision)

This LED indicator light green when a respective port

is in full duplex (FDX) mode. Otherwise, it is blinking
when collisions are occurring on the respective port.

• 100M Link/Activity,10M Link/Activity
(100M LINK/ACT(green), 10LINK/ACT(amber))

This indicator light green when the port is connected

to a 100Mbps Fast Ethernet station, if the indicator
blinking green will be transmitting or received data on
the 100Mbps network. Otherwise, if the indicator light
amber when the port is connected to a 10Mbps
Ethernet station, if the indicator blinking amber will be

10

transmuting or received data on the 10Mbps network.

• Loop Detect for AOW-608 (LOOP)

When this indicator lights amber, it means that there is

a loop detected, then the network needs to be re­configuration.

CONNECTING THE SWITCH

This chapter explains how to connect the Switch to your
Ethernet network. In each of the following figures, the 5­port 10/100M SOHO Switch(AOW-605) is shown.

PC to Switch

A PC can be connected to the Switch via a two-pair
Category 3, 4, 5 UTP/STP straight cable. The PC
(equipped with a RJ-45 10/100Mbps phone jack) should
be connected to any of the 5 ports (1x - 5x).

The LED indicators for PC connection depends on the
LAN card capabilities. If LED indicators are not light after
making a proper connection, check the PC LAN card, the
cable, and the condition and connection of this switch.

The following are possibilities of the LED indicators under
this connection,

1. The “100LINK/ACT,10LINK/ACT” LED indicator

lights green for hookup to 100Mbps speed or
lights amber for hookup to 10Mbps speed.

2. The “Full-Duplex/Collision” LED indicator

depends upon LAN card capabilities whether it’ s
full-duplex or half-duplex.

Hub to Switch

A hub (10 or 100BASE-TX) can be connected to the
SOHO Switch via a two-pair Category 3, 4, 5 UTP/STP

12

straight cable. The connection is accomplished from the
hub uplink (MDI-II) port to any of the Switch (MDI-X) ports:
1x - 5x for the Switch.

A. 10BASE-T Hub

For a 10BASE-T hub, the Switch LED indicators should
light up as the following:

• “Full-Duplex/Collision” indicator is OFF.

• “100LINK/ACT, 10LINK/ACT LED” indicator is

light amber.

B. 100BASE-TX Hub

For a 100BASE-TX hub, the Switch LED indicators
should light up as the following:

• “Full-Duplex/Collision” LED indicator is OFF.

• “100LINK/ACT,10LINK/ACT” LED indicator is light

green.

Hub without Uplink (MDI-II) port

If a hub is not equipped with an uplink (MDI-II) port,
connection can be made using either straight cable or
crossover cable.

A. Using straight cable

When using straight cable, the connection can be made
from the uplink (MDI-II) port of the Switch to any port of
the Hub.

13

B. Using crossover cable

When using crossover cable, the connection can be
made from any (MDI-X) ports of the Switch to any port of
the Hub.

Switch to switch (other devices)

This switch can be connected to another switch or other
devices (routers, bridges, etc.) via a two-pair Category 3,
4, 5 UTP/STP straight or crossover cable.

A. Using straight cable

When using straight cable, this is done from the uplink
(MDI-II) port of the Switch (Switch A) to any of the
10Mbps or 100Mbps (MDI-X) port of the other switch
(switch B) or other devices.

B. Using crossover cable

When using crossover cable, this is done from any (MDI­X) port of the Switch (Switch A) to any of the 10Mbps,
100Mbps (MDI-X) port of the other switch (switch B) or
other devices.

1. The “100LINK/ACT,10LINK/ACT” LED indicator

light green for hookup to 100Mbps speed or light
amber for hookup to 10Mbps speed.

2. The “Full-Duplex/Collision” LED indicator depends

upon LAN card capabilities whether it’ s full-duplex or
half-duplex

14

Port Speed & Duplex Mode

After plugging the selected cable to a specific port, the
system uses auto-negotiation to determine the
transmission mode for any new twisted-pair connection:

If the attached device does not support auto­negotiation or has auto-negotiation disabled, an auto-

sensing process is initiated to select the speed and set
the duplex mode to half-duplex.
