Power Notice:
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 con-
sider 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.
2.2.1 Desktop Installation
To install a Switch on a desktop or shelf, simply complete the following

Step3: 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
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.
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
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.

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.

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.
