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 multimode 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, multitenant 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 halfduplex when moved up to the ON position; full-duplex in
the OFF position.

Pin 2: enables fixed-setting of the TX Port 1 by moving

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

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 (32104°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.

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 O position 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.

Appendix B - Introduction to LAN
& Ethernet Technologies
As communication and business applications become
increasingly complex, computer networking has evolved
as a very important part of the infrastructure.
Communication systems like Local Area Network (LAN)
evolved into sophisticated, powerful, yet flexible
technology. Among the different types of LAN
technologies, Ethernet represents the best in speed, cost,
ease of installation, and supportability.
LAN
Local Area Network (LAN) technology gave personal
computers the power to share resources of hardware and
software. LAN connects personal computers, file servers,
printers, etc. together within a geographical area, usually
a single building. Multiple, widely dispersed LAN
systems are referred to as a wide area network (WAN).
Ethernet Technologies
More than 80 percent of all LANs utilize Ethernet
technology. The Institute of Electrical and Electronic
Engineers (IEEE) standardized Ethernet in IEEE 802.3,
which provides for configuration rules, interaction
requirements, types of media, and data rate.
16
User’s Manual
Fast Ethernet
For networks that need higher transmission speeds, a
faster speed was developed and IEEE next established
IEEE 802.3u, raising the Ethernet speed from 10Mbps to
100Mbps. Thus, fast Ethernet arose and users quickly
began converting from 10Mbps to 100Mbps.
Gigabit Ethernet
The demand for even higher speed created the gigabit
Ethernet at 1000Mbps (or 1Gbps). The newer IEEE
standard for gigabit Ethernet is IEEE 802.3z. The only
cabling media approved is the fiber-optic pair. The IEEE
has already begun discussions to standardize 10Gbps
(“10Gig”) Ethernet.
Ethernet Products
Hub
One of the earlier connection solutions for Ethernet, a
hub (also called a repeater) operates by broadcasting data
to all ports simultaneously, and repeating the process
until the data is received by the intended node. The hub
works through a “shared network” with all of the nodes in
the network segment sharing the same collision domain.
Switches and bridges emerged because of a need to
separate collision domains that are too large, therefore
improving performance and network reliability.
User’s Manual
17
Switch
A switch solves the collision problem by working as a
single domain. A Switch maps the physical Ethernet
addresses of the nodes residing on each network segment
and then allows only the necessary traffic to pass through.
Packets of data are transmitted along with the destination
and source segment.
There are two basic architectures of LAN switches, cutthrough and store-and-forward. Cut-through switches
consider only the destination address before forwarding it
on to its destination segment, but store-and-forward
architecture accepts and then analyzes the entire packet
before forwarding. This allows the switch to stop certain
packet errors from propagating through the network. The
store-and forward switch eliminates redundant or
corrupted packets, thus increasing the efficiency of the
network transmission.
