I NTRODUCTION
This chapter describes the features of the Switch and some
background information about Ethernet/Fast Ethernet switching
technology.
Fast Ethernet Technology
The growing importance of LANs and the increasing complexity of
desktop computing applications are fueling the need for high
performance networks. A number of high-speed LAN technologies
have been proposed to provide greater bandwidth and improve
client/server response times. Among them, 100BASE-TX (Fast
Ethernet) provides a non-disruptive, smooth evolution from the
10BASE-T technology. The non-disruptive and smooth evolution
nature and the dominating potential market base, virtually guarantee
cost effective and high performance Fast Ethernet solutions in the
years to come.
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 Switch is
compatible with all 10Mbps Ethernet environments, it provides a
straightforward upgrade and takes advantage of the existing
investment in hardware, software, and personnel training.
1
Switching Technology
Another approach to pushing beyond the limits of Ethernet technology
is the development of switching technology. A switch bridges and
transmits Ethernet packets at the MAC address level of the Ethernet
protocol, among connected Ethernet or Fast Ethernet LAN segments.
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 load by dividing the local
area network into different segments. Each segment has its own
bandwidth and it does not compete with others for network
transmission capacity.
A switch acts as a high-speed selective bridge between the individual
segments. The switch forwards traffic from origin segment to
destination segment without interfering with any other segments. By
doing this, the total network capacity is multiplied, while maintaining
the same network cabling and adapter cards.
For Fast Ethernet networks, a switch is an effective way of eliminating
problems of uplinking Fast Ethernet 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. The switch
supports both 10Mbps Ethernet and 100Mbps Fast Ethernet, which is
also ideal for bridging between the existing 10Mbps networks and the
100Mbps networks.
LAN Switching technology is a marked improvement over the
previous generation of network bridges, which were criticized by their
higher latencies. Routers have also been used to segment local area
networks. But, the router is expensive, difficult to setup, and
2
maintenance intensive, these make it relatively impractical for the
network. Switch, on the other hand, is less expensive, easier to setup,
and practically maintenance free, which make it an ideal solution to
today’s local area network congestion problems.
Features
This high performance Switch was designed for a network
environment where traffic and the number of users increase
continuously.
The Switch, with their small, desktop size, was specifically designed
for small to middle workgroups. It provides immediate access to a
rapidly growing network through a wide range of user-friendly
functions.
The Switch is ideal for shared bandwidth 10Mbps or 100Mbps
workgroups with multiple high-speed servers. With the highest
bandwidth at 200Mbps (100Mbps full-duplex mode), each port can
provide workstation with congestion-free data-pipe for simultaneous
access to the server.
The Switch is expandable by cascading two or more switches
together. As all ports support 200Mbps, the Switch can be cascaded
from any port and to any number of switches.
The Switch is a perfect choice for 10Mbps network site that could be
upgraded to Fast Ethernet in the future. Ethernet workgroups can
connect to the Switch now, and change adapters and hubs anytime
later without changing the Switch or reconfiguring the network.
The Switch combines dynamic memory allocation with store-andforward switching method to ensure that the buffer is effectively
allocated for each port. It also controls the data flow between transmit
3
and receive nodes to guarantee against all possible packet loss.
This Switch is an unmanaged 10/100Mbps Fast Ethernet Switch that
offers solutions to increase Ethernet workgroup bandwidth. Other key
features are as followed:
?? Uplink (MDI-II, Media Dependent Interface) port for uplink to
another switch or hub.
?? Store and forward switching scheme. 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 auto-sensing
of speed (10/100Mbps) thereby providing you with automatic
and flexible solutions for your network.
?? IEEE 802.3x flow control for full-duplex mo de operation.
?? Back pressure flow control for half-duplex mode operation.
?? Data Forwarding Rate (per port) at wire-speed for both 10Mbps
and 100Mbps speed.
?? Data Filtering Rate (per port) at wire-speed for both 10Mbps
and 100Mbps speed; eliminates all error packets, runts, etc.
?? 16K active MAC address entry table with self-learning and table
ageing.
?? 512KBytes RAM buffer per device.
?? Broadcast storm protection.
?? Three QoS levels support; checked via IP header, 802.1Q
VLAN Tag, and/or selected per port basis.

Twisted-Pair Ports
Use any of these ports to connect network devices (workstations,
hubs, switches, etc.) to the Switch. These ports are MDI-X ports and
you can use ordinary straight-through twisted-pair cables to connect
PCs, workstations, and Servers to the Switch. If you need to connect
the Switch’s MDI-X port to other device’s MDI-X port, you need to
use crossover cable, or connect using the Uplink port (described
below).
Uplink Ports
The Uplink port is a MDI-II port, which means you can connect this
port to another device’s MDI-X port using an ordinary straightthrough twisted-pair cable.
Port 1 and the Uplink port is really the same port, except that their
pin-outs are different. Do not use both Port 1 and the Uplink port at
the same time.
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 and current.
Since the Switch does not include a power on/off switch, plugging
its power adapter into a power outlet will power on the Switch.

Right Panel
The figure below shows the right panel of the switch.
QoS setting DIP switch:
By using the QoS DIP switches, you can set the QoS function. For
detail information on how to setup QoS, please refer to the QoS
Setting section.
LED Indicators
Power (Power Indicator)
This indicator lights green when the hub is receiving power. This LED
is off indicating no power.
FDX and COL (10/100Mbps Full-Duplex and 10/100Mbps
Collision Indicator)
This LED indicator lights green when the respective port is in fullduplex (FDX) mode. It remains off for half-duplex operation. This
LED blinks green when collision occurs on the respective port.
Note: the full-duplex LED lights green when the connected device
supports full-duplex operation.
8
10Link/ACT and 100Link/ACT (10Mbps Link/Activity (amber)
and 100Mbps Link/Activity (green) Indicator)
This indicator lights green when the port establishes 100Mbps
connection. It blinks green when transmitting or receiving data on the
100Mbps network.
This indicator lights amber when the port establishes 10Mbps
connection. It blinks amber when transmitting or receiving data on the
10Mbps network.
QoS (Quality of Service) setting
Quality of Service (QoS) is a networking term that specifies a
guaranteed throughput level. When data packets with QoS priority
information pass through QoS supported device, thes e packets will be
handled with priority. Without certain level of QoS, multimedia
applications such as Streaming Video and Network Conference can be
sluggish or stopped due to network congestions.
This Switch supports leading edge QoS with three levels of priority
settings. The priority can be checked via layer 2 (IEEE802.1Q VLAN
Tagging) and/or layer 3 (IP Header TOS bits). Port-Based Priority is
also provided for user to set traffic prioritization according to the port
number. Port based priority ensures transmission with precedence for
all incoming packets to the selected port(s). This feature reduces
transmission delay and allows effective video switching in multimedia
applications and improves voice-over-packet application quality.

QoS
Note: Please power off the Switch before setting the QoS
dipswitches.
Port-Based QoS:
There are eight ports on this Switch that can be set for Port-Based
QoS. The QoS DIP Switches 1~8 represent port number 3~6 and
11~14. After setting the selected port’s DIP Switch to “Enable”, all
incoming packets to this port will be handled with priority.
IP Header QoS:
The QoS DIP Switch 9 enables/disables IP header QoS feature. When
the DIP Switch is set at “Enable”, the Switch will check each received
data packet and handle the packet according to the TOS bit priority
information.
VLAN Tag QoS:
DIP Switch 10 enables/disables 802.1Q VLAN Tag priority feature.
When the DIP Switch is set at “Enable”, the Switch will check each
received data packet and handle the packet according to the VLA N
tagging priority information.
Note: It is ok to enable all three QoS features, but the Port-Based QoS
supersedes the IP header and VLAN Tag features.

C ONNECTING T HE S WITCH
This chapter describes how to connect the Switch to your Fast
Ethernet network.
PC to Switch
A PC can be connected to the Switch via a two-pair Category 3, 4, 5
UTP/STP straight cables. The PC (equipped with a RJ-45 10/100Mbps
phone jack) should be connected to any MDI-X ports (1x - 16x)
Note: Use CAT5 (or better) cable for 100Mbps connection.
After the connection is made, the port LED on the Switch will show
the status of the connection. If LED indicator does not light after
making a proper connection, check the PC LAN card, the cable, the
Switch, and the Switch port.
The following are the possible LED indicator status for PC to Switch
connection:
1. The “LINK/ACT” LED indicator lights green for 100Mbps
connection, lights amber for 10Mbps connection, or no light
for no connection.
2. The “FDX/COL LED” indicator lights green if the LAN
adapter is in full-duplex mode. It blinks green indicating
collision occurring, and it remains off when the adapter is in
half-duplex mode.
Hub to Switch
A hub (10 or 100BASE-TX) can be connected to the Switch via a
two-pair Category 3, 4, 5 UTP/STP straight cables. Note: Use CAT5
(or better) cable for 100Mbps connection. The connection is
11
accomplished from the hub’s uplink (MDI-II) port to any of the
Switch’s 1~16 (MDI-X) ports.
A. 10BASE-T Hub
For a 10BASE-T hub, the Switch’s LED indicator should light up as
the following:
“FDX/COL” LED indicator is OFF.
“LINK/ACT” LED indicator lights amber.
B. 100BASE-TX Hub
When connecting to a 100BASE-TX hub, the Switch’s LED indicator
should light up as the following:
“FDX/COL” LED indicator is OFF.
“LINK/ACT” LED indicator lights 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 Switch’s
uplink (MDI-II) port to any MDI-X port on the Hub.
B. Using crossover cable
When using crossover cable, the connection can be made from any
regular MDI-X port of the Switch to any MDI-X port of the Hub.
12
Switch to Switch (other devices)
The 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. Note: Use CAT5 (or better) cable for
100Mbps connection.
A. Using straight cable
When using straight cable, this is done from the Switch’s uplink
(MDI-II) port (Switch A) to any of the 10Mbps or 100Mbps (MDI-X)
port of the other switch (switch B) or other device.
B. Using crossover cable
When using crossover cable, connect from any port (MDI-X) of the
Switch (Switch A) to any of the 10Mbps or 100Mbps port (MDI-X) of
the other switch (switch B) or other device.
1.
2.
The “LINK/ACT” LED indicator lights green indicating
100Mbps. It lights amber indicating 10Mbps speed.
The “FDX/COL LED” indicator lights green if the connection is
in full-duplex mode. The LED remains off when the connection
is in half-duplex mode.
Port Speed & Duplex Mode
After a connection is made between the Switch and another Ethernet
device, the Switch uses auto-negotiation to determine the transmission
mode for this twisted-pair connection:
If the attached device does not support auto-negotiation or has
auto-negotiation disabled, an auto-sensing process is initiated to
select the speed and set the duplex mode to half-duplex.
