Preface
This manual describes the installation and usage of the
compact 8-port fast Ethernet switch with one fiber-optic
port. This combination of fiber and TX ports in a
compact box delivers the power of 100Mbps switching
along with the distance of fiber. The compact size is ideal
for using on the desk-top or mounting on the wall. The
fiber port accommodates SC type connector. RJ-45
connects auto-negotiating 10/100BASE-TX transmission.

Introduction
Benefits of Switching
Ethernet switching technology has dramatically boosted
the total bandwidth of a network. It puts configuration
flexibility and bandwidth adaptability into the local
workgroups where the majority of work is generated.
It further eliminates congestion problems inherent to the
CSMA/CD protocol and improves predictable response
time under heavy network loads. Expensive routing
equipment was used in the past to reduce the congestion
under heavy loads.
The new wave of object-oriented client and server
applications demands higher bandwidth and tighter
integration of client workstations with servers. The old
shared-access (hub/repeater) Ethernet technology
provides neither enough bandwidth nor predictable
response time for this new wave of workgroup
computing.
Fast Ethernet switching not only satisfies both technical
and business requirements, but also preserves the user’s
existing investment in the huge 10 Base-T Ethernet
installed Base.
This compatibility ensures a path for users to add,
change, and migrate to Fast Ethernet as demands emerge.
It also provides a low cost and flexible bandwidth
solution directly to local workgroups where the majority
of work is generated, reducing the need for expensive
network equipment.

8-port Ethernet Switch
This compact switch has seven RJ-45 ports and one fiber
port. Each of the RJ-45 port is capable of auto-negotiate
10/100Mbps and full or half-duplex mode. The multi-
mode fiber port is able to accommodate SC connector.
The switch combines fiber and TX ports in a compact
box, providing an inexpensive solution for
interconnecting between buildings in a campus, multi-
tenant location covering large areas or industrial
environment. The fiber port provides the long distance
capability and the space saving compact size makes it
ideal for wall mounting or desktop.
Store-and-forward, true non-blocking architecture and
auto-negotiation are features of this switch to optimize
performance and value of this switch. Installation and
operation involves simply plugging in cabling and
connecting power. This 8-port switch represents
affordable, reliable, and easy-to-use LAN solutions.

Uplink Port
An uplink port allows connection, through the TX ports,
to another regular (i.e. non-uplink) port of a switch or
hub. The labeled uplink port on the switch is located
adjacent to port 7TX. Port 7TX & uplink-port are
mutually exclusive. If port 7TX is in use, the uplink-port
will be automatically disabled and vise versa.
If connecting to an uplink port of a hub or another switch,
any of the regular ports can be used. To connect two
regular RJ-45 ports between any two switches or hubs,
you need a cross-wire cable.
DIP Switch
The DIP switch allows fixed settings. Locate the DIP
switch in the back of the switch. Figure 2 summarizes
these settings.
Pin 1: changes the traffic of the fiber-optic port to half-
duplex when moved up to the ON position; full-duplex in
the OFF position.
User’s Manual8
Pin 2: enables fixed-setting of the TX Port 1 by moving
up to the ON position; activates auto-negotiation in the
OFF setting. Pin 2 must be in the ON position in order to
change port settings with pins 3 and 4.
Pin 3: forces 10Mbps speed on port 1 when in the ON
position; forces 100Mbps speed on port 1 when in the
OFF position. Note: new setting will not be activated
unless fixed-setting is enabled.
Pin 4: forces half-duplex on port 1 when in the ON
position; full-duplex in the OFF position. Note: new
setting will not be activated unless fixed-setting is
enabled.

Installation
Selecting a Site for the Switch
As with any electronic device, do not subject the Ethernet
switch to extreme temperatures, humidity, or
electromagnetic interference. Specifically, the site you
select should meet the following requirements:
• Room temperature of between 0-40°C (32-
104°F)
• Relative humidity of less than 90 percent,
non-condensing.
• Electromagnetic field (RFC) of surrounding
devices not to exceed standards for IEC
801-3, Level 2 (3V/M) field strength.
• Adequate ventilation. Do not block the
ventilation holes on the side of the switch or
the fan exhaust port on the rear of the switch.
• Power outlet located within 1.8Meter of the
switch.
User’s Manual10
Connecting to Power
Connect the supplied AC power cord to the receptacle on
the back of the switch, and then plug the cord into a
standard AC outlet with a voltage range from 100 to 240
VAC.
Turn on the switch by flipping the ON/OFF switch on the
rear of the unit to the I(ON) position. The Oposition is
OFF.
Connecting to Your Network
Consult Table 1 for specific cabling requirements.
Prepare cable with connections corresponding to the port.
Install the same type of connectors at both ends for
proper performance. With the power switch in the OFF
position, connect the cables. No further installation is
necessary.
