1. Introduction
Driven by recent advances in desktop computing technology, today’s
network applications have grown speed, power and the ability to pro-
cess information. To meet the demands of these more powerful applica-
tions, the switch has been developed to alleviate congestion and im-
prove performance on your Ethernet network. The switch comes with
multiple ports, with each capable of transmitting or receiving informa-
tion simultaneously at full wire speed to control and allocate the net-
work bandwidth.
Figure 1-1 Switch Unit
The key features of this switch unit are:
•
Combining one fixed 10/100Mbps-based fast Ethernet switched
port, the switch provides a non-disruptive and smooth migration
path from Ethernet to a Fast Ethernet network.
•
With one expansion slot, the switch allows you to connect an
additional 10/100Mbps auto sensing port or an optional 100Base-
FX fiber optic port module to connect to a Fast Ethernet fiber optic
backbone.
•
Combining multiple speeds and multiple media support in the
same unit, the switch can meet your diversified application
requirements.

2. Installing the Switch
The switch is designed to operate in workgroup environments without a
complicated configuration procedure. It also features an auto-select 100-
240V, 50/60Hz power supply unit, which works in most countries around
the world.
Before connecting the supplied power cord into the switch, check to see
that the cord voltage and current rating conform to the standards of the
country of operation.
2.1 Packing List
The switch has the following components shipped with it:
•
•
•
•
•
One switch unit
One AC power cord
4 rubber feet for desktop mounting
19-inch ack mount kit
Installation guide
2.2 Mounting the Switch
The switch can be placed on a desktop as a stand-alone unit. When in-
stalling the switch on a desktop you need to attach the rubber feet at
each corner of the unit. The rubber feet are included in the product pack-
age. Allow enough ventilation space between the switch and the objects
around it.

Eight 10BASE-T switched ports (Port #1 to Port #8)
Each port consists of an RJ-45 connector and is used for connec-
tion to a 10BASE-T hub or node.
One 10/100BASE-TX switched port (Port #9)
The port consists of an RJ-45 connector and is used for connection
to a 10BASE-T or 100BASE-TX device (hub or node).
Crossover switches for Port #8 and Port #9
Each crossover switch is provided for configuring the pin assign-
ments of the associated RJ-45 connector.
One expansion port slot (Port #10)
The port slot can accommodate one optional port module. Two
types of port modules can be selected. One is a 10/100BASE-TX
port module and the other is a 100BASE-FX port module. Refer to
section 2.4 for how to install the module into the slot.

Diagnostic LED indicators
The indicators provide the operating status of the hub and the
network ports. The status includes power, partition, duplex,
activity, and collision.
Configuration switches
Two configuration switch groups are located on the rear of the switch
unit. The switches are used for configuring the operation settings for all
ports. The settings include mode, speed, and duplex.
2.4 Installing an Optional Port Module
Two types of port modules can be selected for the expansion port slot:
10/100BASE-TX port module
This module comes with one RJ-45 connector and one crossover switch
on the front. It can support either one 10BASE-T connection or one
100BASE-TX connection. For dual-speed support, the module features
the capability of speed auto-sensing.
Figure 2-5 10/100BASE-TX Port Module
100BASE-FX port module
This 100Mbps-based module complies with 100BASE-FX standard and
comes with two ST connectors. It can support one fiber cable segment
to a Fast Ethernet network.

Figure 2-6 100BASE-FX Port Module
Before installing any optional modules, first turn the power to the switch
off. To install a module into the expansion port slot, follow these steps:
1. Turn off the power switch.
2. Remove the cover of the slot.
Figure 2-7 Remove the Slot Cover
3. Align the connector and insert the module until it is fully seated.
Secure it to front panel.
Figure 2-8 Insert Module into the Slot

2.5 Setting the Configuration Switches
Open the configuration switch cover on the rear of the unit. There are
two switch groups as illustrated below:
Figure 2-9 Configuration Switches
The following table specifies the definition of each switch:
The M switch only functions for Port #9 and Port #10. Since Port #1 to
Port #8 are fixed 10BASE-T ports, the speed of these ports is fixed at
10Mbps. No speed selection is available. D1-D8 switches are used for
selecting the duplex mode for each 10BASE-T port respectively.
Port #9 and Port #10 can be configured as NWay auto-negotition ports if the M
switch is set to OFF position. This setting applies to both ports at the same time.
The auto-negotiation mode enables the port to negotiate a common op-
eration mode with the device connected at the remote end of the link
cable. The common operation mode is negotiated in the sequence as
follows:
9
When a operation mode is accepted by the remote device, the mode is used for
the data transfer between the port and the connected device. Full-duplex opera-
tion enables two devices to transfer data bi-directionally at the same time.
For connecting to a hub, refer to the following table for the switch setting:
Port

10BASE-T hub

Half duplex (D=Off)
Auto-negotiation mode
Port #1 - #8
Port #9, Port #10
Port #9, Port #10

For connecting to other device such as another switch or computer,
refer to the following table:
Port
Connecting to
Setting
Port #1 - #8
Port #1 - #8
Port #9, Port #10
Port #9, Port #10
Half-duplex device Half duplex (D=Off)
Full-duplex device Full duplex (D=On)
Non-NWay device Manual mode
NWay device
Auto-negotiation mode
Factory Default Settings
All switches are set to OFF position when the switch unit is shipped out
from factory. That means Port #1 to Port #8 are at half-duplex mode and
Port #9 and Port #10 are at auto-negotiation mode.
Important Note:
As long as any change on the settings of the switch groups is made, you
must turn the power to the switch unit off and turn it on again to make
the change take effect.

3. Making Network Connections
3.1 Network Switched Ports
There are ten ports on the switch for connection to ten LAN segments.
Each segment is an independent shared network in one collision-do-
main.
Figure 3-1 Network Ports
Port #1 to Port #8 are 10Mbps-based 10BASE-T switched ports and
dedicated for connecting to eight separate 10Mbps Ethernet segments
through individual 10BASE-T connections.
Port #9 is a 10/100Mbps-based dual-speed switched port. It can support
connection to either one 10Mbps Ethernet segment or one 100Mbps
100BASE-TX fast Ethernet segment. It features the capability of auto-
sensing the speed of the connected segment.
Port #10 is a configurable expansion port slot. The slot can be config-
ured with one optional port module. Once installed, the slot becomes a
network switched port and can be used for connecting to an additional
network segment. Two optional modules are:
•
•
10/100BASE-TX port module - dual speed 10/100BASE-TX
100BASE-FX port module - 100BASE-FX fiber optic

3.4 100BASE-FX Module
The 100BASE-FX port module supports a connection to a Fast Ethernet
network segment through a fiber optic connection. The module comes
with two ST connectors. One labeled Tx is used for transmission. The
other one labeled Rx is used for reception.
Figure 3-3 100BASE-FX Port Module
When connecting to a 100BASE-FX device using fiber cable, make sure
the Tx connector of the module is connected to the Rx connector of the
device and Rx connector is connected to the Tx connector of the device.
The required fiber optic cable for the connection is 1300nm 62.5/125
mm fiber cable. The maximum distance between the module and the
connected device depends on the device connected and the duplex mode
used for the connection as follows:
Device connected

Note:
The 100BASE-FX module does not support auto-negotiation function.
When the port is set at auto-negotiation mode, it will operate in half-
duplex mode automatically.

4. LED Indicators
4.1 LED Panel
The switch provides comprehensive LED indicators for diagnosing and
monitoring the operation of the unit as illustrated below:
Figure 4-1 LED Indicators
4.2 Interpretation
One Power LED indicates the status of the power supplied to the switch.
Each port has two LEDs to indicate the port status including cable link,
partition state, activity, collision, and duplex mode. Every port has iden-
tical interpretations for the LED display.
The LED can display two different colors. Different colors present dif-
ferent meanings as the table shown below:
Partition : the port is in partitioned state.
Activity : there are packets transmitted or received on the port.
Collision : there are collisions occurred on the port.
