B.  PRODUCT 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-T (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 100Mbps Fast 
Ethernet is compatible with all other 10Mbps Ethernet environments, it 
provides a straightforward upgrade and takes advantage of the existing 
investment in hardware, software, and personnel training. 

Switching Technology 

Another approach to pushing beyond the limits of Ethernet technology 
is the development of switching technology. A switch bridge Ethernet 
packets at the MAC address level of the Ethernet protocol transmitting 
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

, which don’t compete with each other for 

network transmission capacity. 

 


background image

The switch acts as a high-speed selective bridge between the individual 
segments.  The switch, without interfering with any other segments, 
automatically forwards traffic that needs to go from one segment to 
another.  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 chaining 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 for 100BASE-TX networks.  Switches 
supporting both traditional 10Mbps Ethernet and 100Mbps Fast 
Ethernet are also ideal for bridging between the existing 10Mbps 
networks and the new 100Mbps networks. 

Switching LAN technology is a marked improvement over the previous 
generation of network bridges, which were characterized by higher 
latencies.  Routers have also been used to segment local area networks, 
but the cost of a router, the setup and maintenance required make 
routers relatively impractical.  Today  switches are an ideal solution to 
most kinds of local area network congestion problems. 

Features 

The Switches were designed for easy installation and high performance 
in an environment where traffic on the network and the number of user 
increase continuously. 

These Switches provide immediate access to a rapidly growing network 
through a wide range of user-reliable functions. 

The Switches are ideal for deployment with multiple high-speed servers 
for shared bandwidth 10Mbps or 100Mbps workgroups. With the highest 
bandwidth 200Mbps (100Mbps full-duplex mode), any port can provide 
workstations with a congestion-free data pipe for simultaneous access 
to the server. 

The Switches are expandable by cascading two or more switches 
together.  As all ports support 200Mbps, the Switches can be cascaded 
from any port and to any number of switches.

The  LevelOne FSW-2411TX 24port 10/100Mbps 13” Fast Ethernet 
Switch are a perfect choice for site planning to upgrade to Fast Ethernet 
in the future.  Ethernet workgroups can connect to the Switches now, 
and change adapters and hubs anytime later without needing to change 
the Switches or reconfigure the network. 

The Switches combine dynamic memory allocation with store-and-
forward switching to ensure that the buffer is effectively allocated for 
each port, while controlling the data flow between the transmit and 
receive nodes to guarantee against all possible packet loss. 

The  LevelOne FSW-2411TX 24 port 10/100Mbps 13” Fast Ethernet

D.  HELPFUL SUGGESTIONS 

Prior to Installation 

Before installing the Switch and connecting network devices, it is 
important to plan the network's layout. Things you should consider 
include: 

.

Dedicated Bandwidth:

 File servers and other high-traffic hardware 

improve their performance if they have their own dedicated 10Mbps or 
100Mbps bandwidth. 

.

Full-Duplex:

 Determine which devices support Full-Duplex 

connections. 

.

Fast Ethernet:

 Make sure rules for cable lengths and categories are 

followed. 

.

Auto-Negotiation:

 Devices with different speeds may be easily 

swapped when the other end of the cable is fixed to a port with Auto-
Negotiation. 

 

Half- and Full-Duplex 

This  LevelOne 24Port 10/100Mbps 13” Fast Ethernet Switch supports 
both Half- and Full-Duplex modes for 10BASE-T and 100BASE-TX.   

 

• 

In Half-Duplex mode data cannot be transmitted and received at the 

same time.  Attached devices must finish transmitting data before 
they can receive data. 

• 

In Full-Duplex mode data can be transmitted and received at the 

same time.

However:

 

a)  Full-Duplex transmission is only possible between two devices 

with a dedicated link (e.g., Switch-Switch, Switch-PC) 

b)  Both devices must have Full-Duplex capability 

c)  Both devices must be set to Full-Duplex (e.g. Auto-

Negotiation  – Auto-Negotiation, Non-Auto-Negotiation to Non-
Auto-Negotiation) 

• 

The 100BASE-TX/10BASE-T ports on the Switch detect and set the 
line's operating mode by using their Auto-Negotiation function. 

Fast Ethernet 

100BASE-TX is called "Fast Ethernet". In Fast Ethernet data travels ten 

times faster (100Mbps) than in traditional 
Ethernet (10Mbps). 

Below is a list of the cable types and connectors supported by the 

Switch for 10BASE-T and 100BASE-TX 
networks.

Cable Type 

Connector 

10BASE-T  

Category 3, 4 or 5 TP 

RJ-45 

100BASE-TX 

Cat. 5 TP 

RJ-45 

 

Note:

 If your 10BASE-T network currently uses Category 5 TP cabling, 

you can instantly upgrade the network to a 100BASE-TX network by 
changing network devices. 

Auto-Negotiation 

Every 100/10Mbps dual speed port on this  LevelOne FSW-2411TX 24 
port 10/100Mbps 13” Fast Ethernet Switch has a built-in "Auto-
Negotiation" function.  This technology automatically sets the best 
possible bandwidth as soon as a connection is established with another 
network device (usually at Power “On” or Reset).  This capability is 
achieved via the Switch’s Auto-Negotiation function that automatically 
detects the modes and speeds the second (attached) device is capable 
of.   

Evaluating Auto-Negotiation Capability:

If the attached device is: 

This Switch Will Automatically Set Its 
TP Ports to Operate At: 

100Mbps, no Auto-Negotiation 

100Mbps Bandwidth  

(100BASE-TX, Half-Duplex) 

100Mbps, with Auto-Negotiation 

200Mbps Bandwidth  

(100BASE-TX, Full-Duplex) 

10Mbps, no Auto-Negotiation 

10Mbps Bandwidth  

(10BASE-T, Half-Duplex) 

10Mbps, with Auto-Negotiation 

20Mbps Bandwidth  

(10BASE-T, Full-Duplex) 

Helpful Warning:

  If the attached device is set to a fixed mode (ex: 

Forced Full-Duplex) it will not operate as an Auto-Negotiation device. 

MAC Address Table 

Every Ethernet data packet includes both source and destination 
addresses.  This 6-byte ID is called the MAC (Media Access Control) 
Address. 

The Switch can automatically learn and store MAC addresses.  
However, the MAC address table is volatile: it disappears when the 
Switch is powered “Off” or reset. 

Note:

 When the network needs reconfiguration, we recommend 

to restart switch first.  After all nodes have been moved, Remove

 

the power cord and re-attach it on the back panel

  to rebuild the 

internal MAC address table.

II.  100BASE-TX port Link LED is lit, Collision LED is blinking, but 

traffic is irregular. 

Ø 

Check that the attached device is not set to dedicated 
Full-Duplex.  (Some devices use a physical or software 
switch to change Duplex modes.  Auto-Negotiation may 
not recognize this type of Full-Duplex setting). 

 

 

ALWAYS CHECK THAT:
