INTRODUCTION
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
current 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.

2
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 loading by dividing a 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 still
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 traditional 10Mbps Ethernet and 100Mbps Fast
Ethernet, which is also ideal for bridging between the existing
10Mbps networks and the new 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 expensive, difficult to setup, and

3
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 its standard rack-mount size, is perfect for middle to
large workgroups. It provides immediate access to a rapidly growing
network through a wide range of user-reliable 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-and-
forward switching method to ensure that the buffer is effectively
allocated for each port. It also controls the data flow between transmit
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 mode 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 tablewith self-learning and table ageing.
??512KBytes RAM buffer per device.
??Broadcast storm protection.
??Three QoS levels; checked via IP header, 802.1Q VLAN Tag, and/or
selected per port basis.
??Supports two trunking groups for cascading two or more Switches (same
model).

performance. When installing, consider the following pointers:
?? Install the Switch in a fairly cool and dry place. See Technical
Specification for the acceptable operating temperature and
humidity ranges.
?? Install the Switch in a site free from strong electromagnetic
source, vibration, dust, and direct sunlight.
?? Leave at least 10cm of space at the left and right hand side of the
Switch for ventilation.

6
?? Install the Switch on a sturdy, level surface that can support its
weight, or on a 19” EIA standard-size equipment rack. For
information on rack installation, please see the next section, Rack
Mounting.
?? When installing the Switch on a level surface, attach the rubber
feet on the corners at the bottom of the Switch. The rubber feet
cushion the Switch and protect the bottom of the Switch.
Rack Mounting
The switch can be mounted in an EIA standard-size 19-inch rack,
which can be placed in a wiring closet with other equipment. Attach
the mounting brackets at the switch’s side panels (one on each side),
and secure them with the provided screws.
After that, use screws provided with the equipment rack to mount each
switch in the rack.

LED Indicator Panel
Refer to the next chapter for detailed information about each LED
indicator.
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
these ports to devices with MDI-X ports, you need to use crossover
cables, or connect using the Uplinkport (described below).
Uplink Port
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 straight-
through twisted-pair cable.

Trunking setting
This Switch supports trunking function. Trunking function increases
backbone bandwidth and reduces network congestion; this is helpful
when the traffic is heavy between the cascaded Switches.
You can cascade two Switches via one trunking group (max. of 4
ports) with bandwidth up to 800Mbps; or cascade three (or more)

10
Switches via both trunking groups with 800Mbps bandwidth between
the Switches. Please see the table and diagrams below for more
information.
You can select to trunk two Switchesusing 2, 3, or 4 ports with Trunk
Group A or B. Please follow the instructions below to set the trunking
dipswitches:
Note: You can only trunk same model Switches together.
1. Power off the Switch.
2. Follow the table above to select the trunk ports and set the
dipswitches.
3. Repeat step 1 & 2 and configure another Switch.

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, these 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 improvesvoice-over-packet application quality.
