Introduction

8-Port 10/100 Mbps Auto-sensing Dual Speed Switch

Live-FSH8R Fast Ethernet Switch is an 8-port auto-sensing a nd auto-
negotiating Dual-speed Fast Ethernet Switch with one Uplink port. It

is designed with a view to provide SOHO users with maximum benefit
to work in a SOHO LAN environment. All of its 8 RJ-45 station ports

support Dual Speed with auto-sensing and auto-negotiating functions.
The Uplink port is provided for connection with another switch or
hub. All its 8 station ports can automatically a da pt to data rate s ranging
from 10 Mbps (Ethernet half-duplex mode) to 200 Mbps (Fast Ethernet
full-duplex mode). With auto-sensing function, Live-FSH8R
automatically detects the speed of the devices you plugged into, and
routes the incoming data to its destination. Its auto-negotiating function
also allows existing devices with different speeds to communicate
easily within the same network. With these advantages, you have no
further costs for unnecessary or expensive upgrade.

Store-and-Forward Ar chitectur e against Pa cket Loss

It is recognized that when network is under heavy traffic, the shared
memory buffer in the switching devices might yield incorrect detection
due to an overfed memory buffer. This drawback in transmission
sometimes can ha ppen either when data be ing transmitted in IEEE802.
3x Full Duplex or Back Pressure Flow Control mode. To amend this
problem, Live-FSH8R Fast Ethernet Switch utilizes a fixed memory
buffer allocation with Store-and-forward transmission to ensure an
effective buffer allocation for each port. Store-and-forward
transmission controls data flow from transmitting to receiving nodes
with the receiving buffer threshold adjusted to optimal value,
guaranteeing against all possible packet losses.

1-2 Introduction

Active Flow Control

Live-FSH8R Fast Ethernet Switch implements in full duplex mode a
Flow Control, which is compliant to IEEE 802.3x standard. While in
half duplex mode, it employs a n optional Ba ck Pre ssure Flow Control
to stall the incoming data when port buffers being saturated. With
this flow control mechanism, it can be ensured that frames dropped
during tra nsmission are reduced to a minimum.

Non-blocking Wire Speed

Live-FSH8R’s non-blocking cross-bar matrix architecture provides
high-end performance for departmental and workgroup environments
at a fraction of the cost of similar devices. Typically, this type of
architecture is found only in high-end switches designed to handle
huge corporate networks. With bandwidth needs and network efficiency
concerns, Live-FSH8R’s switching fa bric de sign is the perfect answer
for solution. You can take advantages of this high bandwidth
performa nce capa ble of running your data-throughput at excellent speed.
And you’ll appreciate the efficiency and smoothne ss that is brought to
you by this new dimension of Live-FSH8R’s switching architecture.

Broadcast Storm Control

Live-FSH8R is capable of broadcast storm control. A broadcast storm
occurs when a large number of broadcast packets are received from a
given port. Forwarding these packets can cause the network to slow
down or time out. Broadcast storm control defines threshhold for the
number of broadca st pa ckets that can be rece ived from ea ch port bef ore
forwarding is blocked. Specifically , each port will drop broadca st packet
(the Destination ID, or DID, is f f f f ff f f ff f f) after rece iving continuous
64 broadcast packets. The counter will be reset to 0 every 800ms or
when receiving any non-broadca st packet (DID is not ff ff ff ff f f f f).

1-3 Introduction

Perfect Companion f or LAN Users in SOHO Scenario

Live-FSH8R provides f ollowing featur es which you’ll find especially
suitable for SOHO networking. Users who work in a SOHO envir onment
will definitely come to appreciate its numer ous adva ntages:

Compact size making more “elbowroom” on your
SOHO Desktop

The palm-size Live-FSH8R Fast Ethernet Switch is designed to
perfectly fit into you SOHO environment. Its compact size will fit
snugly onto your desktop, and provides more “elbowroom” for your
working space. In a SOHO environment, it not only saves your money
but also your precious space.

Easy Plug-and-Play costs SOHO users No Network
Management Effort

Live-FSH8R Fast Ethernet Switch fully complies with the IEEE 802.3
standard for 10BASE-T network and the IEEE802.3u standard for
100BASE-TX network. And it takes SOHO users almost no effort to
install it in a mixed 10M/100Mbps Ethernet/Fast Ethernet environment.
Simply plug in the power and connect other devices to its ports, and
you just complete its installation. Furthermore, the Switch operates in
a protocol-independent manner, eliminating the overhead for
management software. With its easy Plug-and-Play feature, Live-
FSH8R Fast Ethernet Switch costs SOHO users virtually no effort to
install and run.

Very Cost-effective for SOHO Networking

Live-FSH8R Fast Ethernet Switch is the best choice for a cost-
effective solution for SOHO users to expand, connect or upgrade its
existing 10 Mbps Ethernet to 100 Mbps Fast Ethernet network. With

1-4 Introduction

the implementation of Live-FSH8R Fast Ethernet Switch, it means
that your existing 10 Mbps Ethernet network can be extended to Fast
Ethernet 100 Mbps speed at very effective costs.

LED Information helps users monitor their network status

The LED indicators on the front pa nel show releva nt inf ormation
of your network status. SOHO users can get insta nt inf ormation
from the front-pa nel LEDs: The Power LED indicates the Power
On/Off status. The DIAG LED give s users the functional status
of the Switch as a preliminary diagnostic to warn for possible
hardware failure. The ENLOOP LED
of a network loop when the switch’s loop detection function is
enabled. Ea ch Link/Act LED indicates the linking a nd receiving/
tra nsmitting status of each port, while FDX/Col LED shows the
half-/full-duplex transmission status and the collision status of
your port. The 100 M LED indicates whether the connection is
running at 100 Mbps mode. For detailed LED information, plea se

refer to Chapter 5.

* indicates the existence

What is 10/100 Mbps Dual-Speed Switching?

Current expa nsion of multimedia usage on the network, together with
the new wave of distributed Client/Server applications, creates a much
higher demand for bandwidth and tighter integration of clients and
servers. The legacy shared-access 10Mbps Ethernet technology can
no longer provide adequate bandwidth and predictable response time
to the new workgroup environment.

10/100 Switching is a n integral extension of Fa st Ethernet. It provide s
not only the 100Mbps high-speed “pipeline” for carrying aggregated
10Mbps traffic, but also the necessary bridging between the 10BASE­T a nd 100BASE-TX MAC f ormats.
Fast Ethernet combined with the Switching technology offers an
adequate bandwidth to satisfy the dem and of local workgroups. It also
provides a high-speed link to carry local network traffic elsewhere
within a network.

Ethernet switching technology dramatically boosts the total bandwidth
performance of a LAN network. It also furnishes configuration
flexibility a nd bandwidth adaptability for the local workgroups where
the majority of workload is generated by business applications.
Switching function further eliminates the congestion problem
inherent to the contention-based CSMA/CD protocol, thereby
improving predictable response time under heavy load. While in the
past, this network congestion could only be alleviated by much more
expensive routing technology. With the implementation of switching
technology, Live-FSH8R Fast Ethernet Switch is your perfect solution
to solve network congestion.

Expanding Your Network

4

Live-FSH8R Fast Ethernet Switch not only is targeted as a

concentrator to converge LAN traffic within your Ethernet/Fast
Ethernet network, but also as an efficient switching device to send
incoming data to its destination LAN segment. With your existing
Ethernet infrastructure, you can very easily connect, expand or migrate
to an Ethernet/Fast Ethernet environment.
The following sections will introduce to you the basics of network
connectivity within Ethernet/Fast Ethernet environment.

Connectivity Rule s

Ethernet (10 Mbps)

Ethernet (10Mbps) networks should be configured according to the

following connectivity rules:

" The maximum length for UTP cables must not exceed 100 meters

from end station to a shared-access 10Base-T hub.

" Between any two end stations in a collision domain, there may

be up to five cable segments and four intermediate repeaters at
most.

" If there is a path between any two end-stations containing five

segments and four repeaters, then at least two of the cable
segments must be point-to-point link segments (e.g. 10BASE-T,
10BASE-5), while the remaining segments may be of mixed
segments (e.g. 10BASE-2 or 10BASE-5).

4-2 Expanding Your Network

Fast Ethernet (100 Mbps)

Fast Ethernet (100Mbps) network should be configured according to
the following connectivity rules:

" The maximum length for UTP cables is 100 meters from end

station to a shared-access 100BASE-TX hub.

" In a single collision domain with two repeaters, the maximum

cabling length is 100 meters between an end station and a
repeater, and 100 meters between two switches, thus making a
maximum diameter of 300 meters between two end stations.

Switch-to-Hub Connection

Live-FSH8R Fast Ethernet Switch can be connected to a

10Base-T or 100BASE-TX hub vi a a 4 -pair UTP / STP straight­through cable (Category 3, 4 or 5). Ea ch cable length can be up
to 100 meters long (328 feet). The switch-to-hub connection
can be made through the Uplink daisy-chain port (MDI-II) on
the hub to any of the station ports (MDI-X) on Live-FSH8R.

For a 10BASE-T or 100BASE-TX hub connection, the LED indicators
on the Switch should give the following signals to indicate a proper
and functional connection:

""

" Link/Act LED indicator should be ON

""
""

" FDX/Col LED status will depends on the status of the other

""

connected hub or device

""

" 100 M LED indicator should be ON if connected to 100BASE-

""

TX device, otherwise it should be OFF

Both 10BASE-T and 100BASE-TX network environments
allow uplinking, but each follows different rules for
connection.

4-3 Expanding Your Network

Switch-to-switch (Other Device) Connection

Live-FSH8R Fa st Ethernet Switch ca n be connected to another switch

or other networking device such as a router or bridge by a two-pair
UTP / STP Straight-through or Crossover cable (Category 3, 4, 5).

Using a Straight-through Cable

When using a straight-through cable, the switch-to-switch connection
is done through the Uplink daisy-chain port (MDI-II) of the Switch
to any of the 10Mbps or 100Mbps station port (MDI-X) of another
switch or device.

Using a Crossover Cable

When connecting any 10/100 Mbps station port (MDI-X) of other
switch or device to any station port (MDI-X) of Live-FSH8R Fast
Ethernet Switch, it is required that you use a crossover ca ble.

The LEDs on Live-FSH8R Fast Ethernet Switch corresponding to
the respective connected port should give the following signals to
indicate a proper and functional connection:

""

" Link/Act LED indicator should be ON

""
""

" FDX/Col LED status will depends on the status of the other

""

connected switch or device

""

" 100M LED indicator should be ON if connected to 100BASE-

""

TX connection, otherwise it should be OFF

Connecting with a Switch (or Hub) without Uplink Port

If the switch (or hub) to be connected to Live-FSH8R Fast Ethernet

Switch is without an Uplink daisy-chain port (MDI-II), a switch-to-

switch connection can still be made using either a straight-through
cable or a crossover cable.

4-4 Expanding Your Network

Using Straight-through Cable Connection

When using a straight-through cable, the connection can be made
through the Uplink daisy-chain port (MDI-II) of the Switch to any
station port (MDI-X) of the other switch or hub.

Using Crossover Cable connection

When using a crossover cable, the switch-to-switch connection can
be made from any station port (MDI-X) of Live-FSH8R Fast Ethernet
Switch to any station port (MDI-X) of the other switch or hub.

This requirement differs somehow from the switch-to-node
connection. For the pin assignments of crossover cabling please
refer to Fig 4-3.

Fig. 4-2 Connection through Station Port using
crossover cable

Do not plug a phone jack connector into any RJ-45 port.
This may damage the port. Inste ad, use only twisted-pair
cable with RJ-45 connector that conforms with FCC
standards

Notes:

1. Port #1 is shared with the Uplink daisy-chain port, although their
pinouts are different. Do not use both port #1 and the Uplink Port

(MDI-II) at the same time.

2. Make sure each twisted-pair cable does not exceed 100 meters.

3. To connect to another switch or hub, you may make a connection
with station ports (MDI-X) at both ends if you use crossover cable.

RJ-45 Port Description

RJ-45 station ports (MDI-X) can be attached to any devices, which use a
standard network interface (e.g., a workstation, server, bridge or router).
But the Uplink daisy-chain port (MDI-II) can be cascaded to a station
port on similar networking devices (e.g. another switch or hub).

When cascading multiple switches (or hubs), it is important that the UTP
cables should be of crossover type as shown in the diagram above. Also,
make sure you use the same pair of wire for pin pairs 1-2,3-6,4-5 and 7-

8.

Fig. 4-3 Pin assign ments for crossover cabling

The wire schematics for both straight-through and crossover twisted­pair cables are shown as below:

Fig. 4-4 Wire schematics for straight-through and

crossover cable.

Summary :

" When connecting a computer to a switch, use a straight-through

UTP cable .

" When connecting from the Uplink port (MDI-II) of Live-FSH8R

to a ny station port (MDI-X) of another hub, use a straight-thr ough
UTP cable. Plea se note that the ca bling distance limit is 100 meters

maximum.

" When connecting from a ny station port (MDI-X) of Live-FSH8R

to any station port of other devices, use a crossover cable.

T ra n smission Mode

All 10/100Mbps ports of Live-FSH8R Fast Ethernet Switch utilize
auto-negotiation to determine the transmission mode for any new
connection. This means, if auto-negotiation is supported on both ends
of the connection, the Switch is initiated to negotiate for one of the
following transmission modes:

Applications

Gear Up Network Performance for SOHO Networking

Live-FSH8R Fast Ethernet Switch serves primarily as a concentrator
to converge your SOHO network traffic, and as a highly efficient
switching device to forward the incoming data to its destination
network segment. With its auto-sensing and –negotiating functions,
it makes your mixed Ethernet/Fast Ethernet networking environment
as efficient and compatible. Not only ca n you expand or upgrade from
10Mbps to 100 Mbps Fast Ethernet bandwidth with

4-8 Expanding Your Network

virtually no effort, but also your existing Ethernet investment are saved
for your leverage. It is a perfect solution to cater to SOHO users’ later
network expansion needs. With its Uplink Port, Live-FSH8R is
extremely flexible in network configuration. Through uplinking multiple
switches, hubs or other devices, plenty of flexibility and expandability
is left for the SOHO users to apply in future LAN configuration and
expansion.

Since Live-FSH8R provide such a cost-effective way to gear up your
SOHO network performance, you will appreciate the easy Plug-and-
Play installation within your SOHO network.

Fully compatible with either 10/100 Mbps connection in either half/
full duplex tra nsmission mode, Live-FSH8R ca n ea sily connect devices
with different transmission speeds. You can rely on Live-FSH8R to
serve as an effective switching device for your SOHO network.

Live-FSH8R Fast Ethernet Switch can significantly improve your
network performance through effectively segmenting your network
traffic. The result is an increasing bandwidth and throughput that can
be experienced by LAN users. Either of the 8 station ports of Live-
FSH8R can be attached to a hub (i.e., shared collision domain) or
serve as a dedicated link to a single network device (e.g., a workstation).
When a port on the Switch is connected to an Ethernet hub (i.e., a 10
or 100 Mbps repeater), the bandwidth provided by that port is shared
by all the devices connected to the attached hub. However, when a
port is connected to an end node or to a device that breaks up the
collision domain (e.g., a nother Switch, bridge or router), the attached
device has access to the full bandwidth provided by that port.
Microsegmentation of an existing LAN can improve network latency
a nd increase overall performance.

Live-FSH8R Fast Ethernet Switch also uses Store-and-Forward
switching to manage network traf fic, thus ensuring data integrity under
heavy load.

4-9 Expanding Your Network

With such versatility and flexibility plus a very cost-effective a nd ea sy
installation, you will appreciate Live-FSH8R as your best choice for
easy migration to a 100 Mbps Fast Ethernet network yet preserving
your existing 10 Mbps network architecture.
For details on the cabling requirements, please refer to Chapter 3
a nd 4.

Since it is very possible that your SOHO network will expand to a
considerable size along with your business expansion, you might wish
to accommodate your future expansion need with your Live-FSH8R.
In fact, we can envision a “more sophisticated” network expansion
from your SOHO network as seen in Fig. 4-5. As you can see, users of
Live-FSH8R are still left with a great expandability for future network
growth.

T

he front-panel LED indicators enable users of Live-FSH8R Fast

Ethernet Switch to monitor the Power On/Off status and the func-

tional status of the Switch as well as the port status of each of its eight
10/100 Mbps station ports. For the layout of LED indicators, please
refer to Fig. 5-1 below.

As seen on Fig. 5-1, the Power LED indicates the power on/off
status of the switch. The DIAG LED shows the functional sta-
tus of the Switch. The ENLOOP LED warns for the existence
of a network loop. For each station port, there are Link/Act
(Link/Activity), FDX/Col (Full-duplex) and 100M LED to indi-
cate its corresponding port status. You’ll find the LED indicators
to be a very convenient way for switch or port status monitoring
a nd troubleshooting.

Before connecting any network device to Live-FSH8R Fast Ethernet
Switch, you should take a few minutes to look over this section and
get familiar with the front panel LED indicators of your Switch.

5-2 LED Indicators

LED Status during Power-on Self-test

If the network and power source has been properly established, you
are now ready to a ctivate your Switch. While first turning on the switch,
Power LED light is on to indicate the Switch is activated. Meanwhile,
all station port LEDs such a s Link/Act, FD X/Col, a nd 100 M LEDs will
blink about 3 seconds. During this brief period, the Switch is perf orm­ing a auto-checking on LEDs to ensure they can function properly.
The flashing duration for LEDs is determined by the RC value.

After the Power-on Self-test is over, the Power LED will remain lighted
as long as the Switch is not turned off, while port status LEDs (Link/
Act, FDX/Col, and 100 M LEDs) will begin to function and give spe­cific information on corresponding port status.

Power LED

Power LED will give a steady green light when you turn on the
Switch, and will be off when the Switch being turned off. You can
simply check the Power LED status to see if the Switch is being
activated or not. Before turning on the Switch, please verify that the
power cord has been properly connected the Switch to the power

outlet on the wall.

Fig. 5-2 Power-On LED test

DIAG LED

The DIAG LED provides you with diagnostic information about the
functional status of Live-FSH8R. When the Switch functions normally,
the DIAG LED is of f. A constant blinking DIAG LED indicates either
internal memory check has failed. Normally , this LED should always be
off to indicate a normal system status. If you do find the Status LED
keeps blinking persistently, it indicates a possible hardware
malfunction. To troubleshoot the problem, just turn off the system
power for a few seconds and then turn on again in an attempt to reset
the system back to normal. However, if this problem still persists and
the blinking yellow light of the DIAG LED won’t go of f, plea se conta ct
your local dealer for technical support.

ENLOOP LED

The ENLOOP LED indicates the existence of a network loop when the

loop detection function is enabled on the Switch*.

When a port is operating with auto-negotiation to run in full

duplex mode, its corresponding Link/Act LED will show a

blinking green light indicating a data link being established
between the port and the device. This is because, in full duplex
mode, the Switch will send a P AUSE pa cket to indicate the trans­mitter to start sending packets. Thus, the Link/Act LED will
remain blinking to indicate this state in full duplex mode, no
matter the port is transmitting or receiving packets or not.

Conversely, when in half duplex mode, the Link/Act LED will

When in full-duplex tra nsmission mode, FD X/Col LED gives
forth a solid yellow light. When in half-duplex mode, it will be
off. But, when in half-duplex mode, there are two or more end
stations on the same network segment attempting to transmit
data at the same time, a collision occurs. If there is a collision
detected on specific network segment, the corresponding FDX/
Col LED shows a blinking yellow light. When a collision
occurs, all of the stations involved will recognize the collision,
wait a ra ndom a mount of time, and retransmit.

FDX/Col LED status is summarized a s follows:

" ON :Tra nsmission in full-duplex
" OFF:Transmission in half-duplex
" Blinking :Collision detected

# 100 M LED (Transmission Speed Indicator)

##

100M LED showing a steady red light indicates that the line

speed going through that specific 10/100 Mbps port is operating
at 100Mbps mode. If the transmission speed operates only at
10 Mbps, it is off.

Troubleshooting

This appendix contains information to help you identify a nd solve problems.
If your switch does not function properly, please make sure it is set up
according to the instructions on the manual.
If you suspect your switch is not connected correctly to your network,
check the following points before you conta ct your local dealer for support.

" Make sure that the maximum cable length between switch and end

node does not exceed 100 m.

" Make sure that the maximum repeater-to-re peater cable dista nce doe s

not exceed 205 meters.

" Verify that the cabling type used is correct (Category 5 UTP).
" Check the Link/Act LED lights on the front panel to see if it lights

up. If it does not light up, that means a faulty connection. Check
the status of the cable attachment. If the problem persists, try a
different cable.

" Check the DIAG LED to see if it is blinking. If it blinks persistently ,

that means the internal memory check has failed.

" Try another port on the Switch.
" Turn off power supply to the Switch. After a while, turn it on again

to see if it resumes to its normal function.

" Utilize the LED information to troubleshoot your problem. Please

refer to Chapter 5 LED indicators.

If you find out where the problem is but can not solve it by yourself, or
you simply cannot locate what is at fault, please conta ct your local dealer
for technical support.
