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 consider using UPS (Uninterrupted
Power Supply) for your device. It will prevent
you from network data loss or network down-
time.
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.

3. Switch Operation
3.1 Address Table
The Gigabit Ethernet 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 Gigabit Ethernet Switch.
3.2 Learning
When one packet comes in from any port. The Gigabit Ethernet
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 ltering for future packets.
3.3 Forwarding & Filtering
When one packet comes from some port of the Gigabit Ethernet
Switch, it will also check the destination address besides the
source address learning. The Gigabit Ethernet Switch 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 Gigabit Ethernet Switch 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 ltered. Thereby increasing the network
throughput and availability.

16
3.4 Store-and-Forward
Store-and-Forward is one type of packet-forwarding techniques.
A Store-and Forward Gigabit Ethernet Switch 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 efciency and stability.
The Gigabit 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 congured
in any Ethernet network environment to signicantly boost
bandwidth using conventional cabling and adapters.
Due to the learning function of the Gigabit Ethernet Switch,
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 lter packets whose
destination address is on the same segment as the source
address. This connes network trafc to its respective domain,
reducing the overall load on the network.
The Gigabit Ethernet Switch performs “Store and Forward"
therefore, no error packets occur. More reliably, it reduces the
re-transmission rate. No packet loss will occur.

17
3.5 Auto-Negotiation
The STP ports on the Gigabit Ethernet 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
Gigabit Ethernet Switch is not functioning properly, make sure
the Gigabit 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 Gigabit Ethernet Switch.
Performance is bad
Solution:
Check the speed duplex mode of the partner device. The Gigabit
Ethernet Switch 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 trafc 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 Gigabit Ethernet Switch doesn’t connect to the
network
Solution:
Check per port LED on the Gigabit Ethernet Switch. Try another
port on the Gigabit Ethernet 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.
