24-Port 100BASE-TX Fast Ethernet Switch 

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.

3 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 

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. 

3.2 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.

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. 

Port Type 

Cable Type 

Connector 

10BASE-T   

Category 3, 4 or 5 TP 

RJ-45 

100BASE-TX Cat. 

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)

10Mbps 

no Auto-Negotiation 

10Mbps (10BASE-T, Half-Duplex) 

10Mbps 

with Auto-Negotiation 

20Mbps (10BASE-T, Full-Duplex) 

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)

Application 

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