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  
14  
 
an internal buffer, do the complete error checking before transmission.  
Therefore, no error packets occurrence, it is the best choice when a  
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 existence 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 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). This is done by detect the modes and speeds at the  
second of both device is connected and capable of, both 10Base-T and  
100Base-TX devices can connect with the port in either Half- or Full-  
Duplex mode. 1000Base-T can be only connected in Full-duplex mode.

If attached device is:  
100Base-TX port will set to:  
• 10Mbps, no auto-negotiation  
10Mbps  
• 10Mbps, with auto-negotiation 10/20Mbps (10Base-T/Full-Duplex)  
• 100Mbps, no auto-negotiation  
100Mbps  
• 100Mbps, with auto-  
negotiation  
100/200Mbps (100Base-TX/Full-  
Duplex)

4. Troubleshooting  
This chapter contains information to help you solve issues. If the  
Ethernet Switch is not functioning properly, make sure the Ethernet  
Switch was set up according to instructions in this manual.  
The per port LED is not lit  
Solution: Check the cable connection of the FGSW-2620.  
Performance is bad  
Solution: Check the speed duplex mode of the partner device. The  
FGSW-2620 is run at Auto-negotiation mode and if the  
partner is set to half duplex, then the performance will be  
poor.  
Per port LED is lit, but the traffic is irregular  
Solution: 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 recognize  
this type of full-duplex setting.  
Why the Switch doesn’t connect to the network  
Solution: Check per port 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. After a while,  
turn on power again.
