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.

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 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

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 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-and­forward 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 table with 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).

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 Uplink port (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 straight­through twisted-pair cable.

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 improves voice-over-packet application quality.

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 these ports 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 VLAN
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.

13

C ONNECTING THE SWITCH

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 of the 16 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 or lights amber for 10Mbps connection.

2. The “FDX/COL LED” indicator lights green if the LAN

adapter is in full-duplex mode. The LED 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
accomplished from the hub’s uplink (MDI-II) port to any of the
Switch’s 1~16 (MDI-X) ports.

15

A. 10BASE-T Hub

For a 10BASE-T hub, the Switch LED indicators 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 LED indicator
should light up as the following:

“FDX/COL” LED indicator is OFF.
“LINK/ACT” LED in dicator 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 ma de from Switch’s
uplink (MDI-II) port to any port of the Hub.

B. Using crossover cable

When using crossover cable, the connection can be made from any
regular ports of the Switch to any port of the Hub.

16

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, this is done from any (MDI-X) port of
the Switch (Switch A) to any of the 10Mbps, 100Mbps (MDI-X) port
of the other switch (switch B) or other device.

1. The “LINK/ACT” LED indicator lights green indicating

100Mbps connection or it lights amber indicating 10Mbps
speed.

2. 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 system 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 dupl ex mode to half-duplex.
