PowerNotice
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.
2. In some area, installing a surge suppression device may also
help to protect your Switch from being damaged by unregulated
surge or current to the Switch or the power adapter.
2.2 Installing a FGSW-2620
This part describes how to install your Ethernet Switch 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 complete the following steps.

5
2.2.1 Desktop Installation
To install a Switch on a desktop or shelf, simply complete the following steps:
Step1: Attach the rubber feet to the recessed areas on the bottom of the Switch.
Step2: Place the Switch on a desktop or shelf near an AC power source.
Step3: Keep enough ventilation space between the Switch and the surrounding objects.
Note:
When choosing a location, please keep in mind the environmental
restrictions discussed in Chapter 1, Section 4, Specification.
Step4: 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 Switch.
B. Connect the other end of the cable to the network devices such as printer
servers, workstations or routers…etc.
Note:
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.
Step5: 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.
2.2.2 Rack Mounting
To install the Switch in a 19-inch standard rack, follow the instructions described below.
Step1: Place your Switch on a hard flat surface, with the front panel positioned towards
your front side.
Step2: 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.
Figure 2-3 Attaching the brackets to the Switch

 Caution:
You must use the screws supplied with the mounting brackets. Damage
caused to the parts by using incorrect screws would invalidate your
warranty.
Step3: Secure the brackets tightly.
Step4: Follow the same steps to attach the second bracket to the opposite side.
Step5: 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.
Figure 2-4 Mounting the Switch in a Rack
Step6: Proceed with the steps 4 and steps 5 of section 2.2.1 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 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.

8
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 problems. 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.
