2.3.1 10/100Mbps TP Ports  
Each 10/100Mbps 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.  
Users only need to connect a network device into any TP port. Auto-MDIX is also supported on all  
TP ports which allows uplinking to another Switch free of cross-over or straight cable selection  
hassle.  
2.3.2 Cabling  
10Mbps -When transmitting at 10Mbps Category 3, 4 or 5 TP cabling with RJ-45 sockets can be  
used.  
100Mbps -To transmit at 100Mbps requires Category 5 TP cabling.

INSTALLATION  
The LevelOne 11" Fast Ethernet Switch is "Plug-&-Play". It does not require software  
configuration. Users can immediately use any of the features of this product simply by attaching  
the cables and turning on the power.  
If user need advanced smart functions to manage LAN network more effectively, we provide  
software and cable for easy configuration of the Switch. Please see section 5 and 6 for further  
details.  
3.1  
3.2  
To locate the switch on a desktop  
Attach the Four (4) rubber feet included in the product package to the bottom of the Switch, one  
in each corner.  
Place the Switch on a clean, flat desk or tabletop close to a power outlet.  
Plug in all network connections and the power cord.  
Rackmount placement  
Attach One (1) rackmounting bracket on each side of the Switch front panel and secure each  
bracket with the provided screws.  
Use the other provided screws to secure each Switch to the rack.

HELPFUL SUGGESTIONS  
4.1  
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.  
4.2  
Half- and Full-Duplex  
The 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:  
Full-Duplex transmission is only possible between two devices with a dedicated link (ex:  
Switch-Switch, Switch-PC)  
Both devices must have Full-Duplex capability  
Both devices must be set to Full-Duplex (ex: 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.  
4.3  
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.

Connector  
RJ-45  
10BASE-T  
100BASE-TX  
Category 3, 4 or 5 TP  
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.  
4.4  
Auto-Negotiation  
Every 10/100Mbps dual speed port on the 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 attached device is:  
The Switch will automatically set its TP ports to  
operate at:  
100Mbps  
no Auto-Negotiation  
100Mbps (100BASE-TX, Half-Duplex)  
100Mbps  
with Auto-Negotiation  
200Mbps (100BASE-TX, Full-Duplex)  
7
 
10Mbps  
10Mbps (10BASE-T, Half-Duplex)  
20Mbps (10BASE-T, Full-Duplex)  
no Auto-Negotiation  
10Mbps  
with Auto-Negotiation  
Note: If the attached device is set to a fixed mode (ex: Forced Full-Duplex) it will not operate as  
an Auto-Negotiation device.  
4.5  
MAC Address Table  
Every Ethernet data packet includes both source and destination addresses. This Six (6)-bytes 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 turning off the power first. After  
all nodes have been moved, turn the Switch back "On" to rebuild the internal MAC address table.  
4.6  
Broadcast Storm Control (only for FSW-1620TX)  
The Broadcast Storm Control discards broadcast frames when the number of cumulated  
non-unicast frames is over the threshold, in order to prevent Network Traffic congestion bringing  
the Network to a halt. In this Switch, each port will drop broadcast packets (Destination MAC ID is  
ff ff ff ff ff ff) after receiving continuous 64 broadcast packets. The counter will be reset to 0 every  
800ms or when receiving any non-broadcast packets. (Destination MAC ID is not ff ff ff ff ff ff)

Sample Application  
The optimal application for the Switch is as a "big pipe" backbone interconnecting file servers  
with bandwidth-hungry workgroups, departments, and offices.
