2. Hardware Description  
This product provides two different running speeds – 10Mbps, 100Mbps  
in the same Switch and automatically distinguishes the speed of  
incoming connection.  
This section describes the hardware features of FNSW-4800. For easier  
management and control of the Switch, familiarize yourself with its  
display indicators, and ports. Front panel illustrations in this chapter  
display the unit LED indicators. Before connecting any network device  
to the FNSW-4800, read this chapter carefully.  
2.1 Front Panel  
The Front Panel of the FNSW-4800 Fast Ethernet Switch consists of 48x  
Auto-Sensing 10/100Mbps Ethernet RJ-45 Ports, the LED Indicators are  
also located on the front panel of the FNSW-4800.

1. The device is a power-required device, it means,  
it will not work till it is powered. If your networks  
should active all the time, please consider using UPS  
(Uninterrupted Power Supply) for your device. It  
will prevent you from network data loss or network  
downtime.  
Note  
2. In some area, installing a surge suppression device  
may also help to protect your FNSW-4800 from  
being damaged by unregulated surge or current to  
the FNSW-4800.  
2.3 Hardware Installation  
This part describes how to install your FNSW-4800 and make  
connections to the Switch. Please read the following topics and perform  
the procedures in the order being presented. To install your Switch on  
a desktop or shelf, simply completed the following steps.  
2.3.1 Desktop Installation  
To install a Switch on a desktop or shelf, simply completed the following  
steps:  
Step 1: Attached the rubber feet to the recessed areas on the bottom  
of the Switch.  
Step 2: Place the Switch on a desktop or shelf near an AC power  
source.  
Step 3: Keep enough ventilation space between the Switch and the  
surrounding objects.  
 
When choosing a location, please keep in mind the  
environmental restrictions discussed in Chapter 1,  
Section 4, Specification.  
Note  
Step 4: Connect your Switch to network devices.  
A. Connect one end of a standard network cable to the 10/100  
RJ-45 ports on the front of the FNSW-4800 Switch.  
B. Connect the other end of the cable to the network devices  
such as printer servers, workstations or routers…etc.  
Connection to the Switch requires UTP Category  
5
network cabling with RJ-45 tips. For more information,  
please see the Cabling Specification in Appendix A.  
Note  
Step 5: Supply power to the Switch.  
A. Connect one end of the power cable to the Switch.  
B. Connect the power plug of the power cable to a standard wall  
outlet then power on the Switch.  
When the Switch receives power, the Power LED should remain solid  
Green.  
2.3.2 Rack Mounting  
To install the Switch in a 19-inch standard rack, follow the instructions  
described below.  
Step 1: Place your Switch on a hard flat surface, with the front panel  
positioned towards your front side.  
Step 2: Attach a rack-mount bracket to each side of the Switch with  
supplied screws attached to the package. Figure 2-3 shows  
how to attach brackets to one side of the Switch.  
10  
 
Figure 2-3 Attaching the brackets to the Switch  
You must use the screws supplied with the mounting  
brackets. Damage caused to the parts by using incorrect  
screws would invalidate your warranty.  
Caution  
Step 3: Secure the brackets tightly.  
Step 4: Follow the same steps to attach the second bracket to the  
opposite side.  
Step 5: After the brackets are attached to the Switch, use suitable  
screws to securely attach the brackets to the rack, as shown  
in Figure 2-4.

Step 6: Proceed with the steps 4 and steps 5 of section 2.3.1 Desktop  
Installation to connect the network cabling and supply power  
to your Switch.

3. Switch Operation  
3.1 Address Table  
The Switch is implemented with an address table. This address table  
composed of many entries. Each entry is used to store the address  
information of some node in network, including MAC address, port  
no, etc. This information comes from the learning process of Ethernet  
Switch.  
3.2 Learning  
When one packet comes in from any port. The Switch will record the  
source address, port no. And the other related information in address  
table. This information will be used to decide either forwarding or  
filtering for future packets.  
3.3 Forwarding & Filtering  
When one packet comes from some port of the Ethernet Switching,  
it will also check the destination address besides the source address  
learning. The Ethernet Switching will lookup the address-table for the  
destination address. If not found, this packet will be forwarded to all  
the other ports except the port which this packet comes in. And these  
ports will transmit this packet to the network it connected. If found,  
and the destination address is located at different port from this packet  
comes in, the Ethernet Switching will forward this packet to the port  
where this destination address is located according to the information  
from address table. But, if the destination address is located at the  
same port with this packet comes in, then this packet will be filtered.  
Thereby increasing the network throughput and availability.  
3.4 Store-and-Forward  
Store-and-Forward is one type of packet-forwarding techniques. A  
Store-and Forward Ethernet Switching stores the incoming frame in  
an internal buffer, do the complete error checking before transmission.  
Therefore, no error packets occurrence, it is the best choice when a  
12  
 
network needs efficiency and stability.  
The Ethernet Switch scans the destination address from the packet-  
header, searches the routing table provided for the incoming port  
and forwards the packet, only if required. The fast forwarding makes  
the switch attractive for connecting servers directly to the network,  
thereby increasing throughput and availability. However, the switch is  
most commonly used to segment existing hubs, which nearly always  
improves overall performance. An Ethernet Switching can be easily  
configured in any Ethernet network environment to significantly boost  
bandwidth using conventional cabling and adapters.  
Due to the learning function of the Ethernet switching, the source  
address and corresponding port number of each incoming and outgoing  
packet are stored in a routing table. This information is subsequently  
used to filter packets whose destination address is on the same  
segment as the source address. This confines network traffic to its  
respective domain, reducing the overall load on the network.  
The Switch performs "Store and Forward" therefore, no error packets  
occur. More reliably, it reduces the re-transmission rate. No packet loss  
will occur.  
3.5 Auto-Negotiation  
The STP ports on the FNSW-4800 switch have built-in "Auto-  
negotiation". This technology automatically sets the best possible  
bandwidth when a connection is established with another network  
device (usually at Power On or Reset). Detecting the modes does this  
and speeds at the second of both devices are connected and capable  
of, both 10Base-T and 100Base-TX devices can connect with the port in  
either Half- or Full-duplex mode.  
If attached device is:  
100Base-TX port will set to:  
• 10Mbps, no auto-negotiation  
10Mbps  
10/20Mbps  
(10Base-T/Full-Duplex)  
• 10Mbps, with auto-negotiation  
• 100Mbps, no auto-negotiation  
• 100Mbps, with auto-negotiation  
100Mbps  
100/200Mbps  
(100Base-TX/Full-Duplex)

4.Troubleshooting  
This chapter contains information to help you solve issues. If the Switch  
is not functioning properly, make sure the Ethernet Switch was set up  
according to instructions in this manual.  
The Link/Act LED is not lit  
Check the cable connection of the Switch.  
Solution  
Performance is bad  
Check the speed duplex mode of the partner device. The  
FNSW-4800 is run at Auto-negotiation mode and if the  
partner is set to half duplex, then the performance will  
Solution  
be poor.  
100Base-TX port link LED is lit, but the traffic is irregular  
Check that the attached device is not set to dedicate full  
duplex. Some devices use a physical or software switch  
to change duplex modes. Auto-negotiation may not  
Solution  
recognize this type of full-duplex setting.  
Why the Switch doesn’t connect to the network  
Check the LNK/ACT LED on the Switch Try another port  
on the Switch Make sure the cable is installed properly  
Make sure the cable is the right type Turn off the power.  
Solution  
After a while, turn on power again..
