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.  
The switch acts as a high-speed selective bridge between the individual  
5
 
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 Switches 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-1611TX 16Port 10/100Mbps 13” Fast Ethernet

Port Speeds  
100/10Mbps TP Ports  
Each 100/10Mbps TP port provides an Auto-Negotiation function that  
senses for the attached device's maximum operating speed and  
automatically sets the Switch to operate at that speed. Each TP port  
uses RJ-45 connector that allows network TP cables to be easily  
attached or removed. Users only need to connect a network device into  
any TP port and the Switch will do the rest.  
Crossover Connector  
The last TP port in this model supports a Crossover function. The  
Crossover function is used for Uplinking to a standard port on another  
Switch using normal TP cable.  
F Warning: You cannot use the last TP port’s regular port when you  
are using the Crossover port.  
Cabling  
10Mbps – Category 3, 4, or 5 TP cabling can be used for transmitting  
data at 10Mbps or 20Mbps bandwidth on 10BASE-T networks.  
100Mbps – Only Category 5 TP cabling can be used for transmitting  
data at 100Mbps or 200Mbps bandwidth on 100BASE-TX networks.

D. HELPFUL SUGGESTIONS  
Prior to Installation  
Before installing this LevelOne FSW-1611TX 16Port 10/100Mbps 13”  
Fast Ethernet Switch and connecting it to 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.  
? Crossover Uplink: This LevelOne 16Port 10/100Mbps 13” Fast  
Ethernet Switch can be Uplinked to another Switch using the  
Crossover function located on the last TP port.  
F Remember - If you are using the last TP port’s Crossover port, you  
cannot use the last TP port’s regular port. ` If you use both of the last  
port's ports at the same time your Switch will not operate properly.  
Half- and Full-Duplex  
This 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  
13  
 
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.  
Auto-Negotiation  
Every 100/10Mbps dual speed port on this LevelOne FSW-1611TX  
10/100Mbps 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:

20Mbps Bandwidth  
(10BASE-T, Full-Duplex)  
F 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.  
Sample Application  
The optimal application for this Switch is to interconnect file servers  
with other bandwidth-hungry workgroups, departments, and offices all  
with dedicated bandwidths.

E. Troubleshooting  
I. Link LED does not lit after cable is connected to the port.  
Ø
Verify that the other end of the cable is connected to a  
device that is powered on and on-line.  
Ø
For TP cable connection to another Switch or Hub, verify  
that only one end of the cable is connected to a  
“Crossover” port.  
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).
