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.

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

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.
