2. Introduction To 10/100/1000Mbps Gigabit Switch
2.1 General Description
The device is apowerful, high-performance 10/100/1000Mbps Fast Ethernet and
Gigabit switch, with all 8 ports capable of 10/100/1000Mbps auto-negotiation
operation (NWay), which means the switch could automatically negotiate with the
connected partners on the network speed and duplex mode. Moreover, the
10/100/1000Mbps auto-sensing ability provides an easy way to migrate 10Mbps to
100Mbps or1000Mbps networks with no pain. Compared to the shared10Mbps,
100Mbps or 1000Mbps networks, the switch delivers a dedicated10/100/1000Mbps
connection to every attached client with no bandwidth congestion issue.
All Gigabit ports support auto-negotiation operation, auto MDI-X crossover function
and full-duplex mode. They are ideal for micro-segmenting large networks into
smaller, connected subnets for improved performance, enabling the bandwidth
demanding multimedia and imaging applications. The device also provides the fat
pipe to the servers or backbone connection for boosting the total system
performance.
Store-and-forward switching mode promises the low latency plus eliminates all the
network errors, including runt and CRC error packets. To work under full-duplex
mode, transmission and reception of the frames can occur simultaneously without
causing collisions as well as double the network bandwidth.
The switch is plug-n-play without any software to configure and also fully compliant
with all kinds of network protocols. Moreover, the rich diagnostic LEDs on the
front-panel can provide the operating status of individual port and whole system.
For network connection:
The switch can use the following types of cabling:
10BASE-T: Category 3, 4 or 5 UTP/STP
100BASE-TX: Category 5 UTP/STP
1000BASE-T: Category 5 UTP/STP
Category 5 cable is preferred to use with this product in structured wiring
environments. Thiswill ensure correct operation of all ports at 10Mbps,
100Mbps or 1000Mbps.

LED Definition
The rich diagnostic LEDs on the front-panel can provide the operating status of
individual port andwhole system. The following table is a summary for LEDs
definition.

FDX Off Half-duplex mode
Remark: Gigabit Connection
When the port is connected as 1000Mbps, 100M and 10M LED will bright
green at the same time. Otherwise, the 100M LED will bright alone for
indicating the connection as 100Mbps on the network. So does 10M LED.
2.3.1 System LEDs
System LED indicators are located on the front panel for showing the operating
status of the whole device.
2.3.1.1 Power LED
This indicator lights green when the switch is receiving power;
otherwise, it is off.
2.3.2 Port LEDs
Port LED indicators are located on the front panel forshowing the operating
status of each port.

8
2.3.2.1 Speed/Link and Act LED
Every port has three LED(100M, 10M,Activity) for indicating the speed
and connection status.
If the port is connected but the Speed/Link LED(100M/10M) and
Activity(ACT) LED is dark, check the following items:
1. The switch and the connected device’s power are onor not
2. The port’s cable is firmly seated in its connectors in the switch
and in the associated device.
3. The connecting cable is good and with correct type
4. The connecting device, including any network adapter is functioning.
2.3.2.2 FDX LED
If the FDX lights amber, it means that the port is under full-duplex
operation or dark for half-duplex mode.
2.4 The Rear Panel
The rear panel of the switch is shown as below.
2.4.1 Power Connecting
For compatibility with electric service in most areas of the world, the switch’s
power supply automatically adjusts to line power in the range 100-240 VAC
and 50-60 Hz.
Plug the female end of the power cord firmly into the receptacle on the rear
panel of the switch. Plug the other end of the power cord into an electric
service outlet then the power will be ready.

3. Installing and Using 10/100/1000Mbps Gigabit Switch
3.1 Installing The 10/100/1000Mbps Gigabit Switch
The switch does notrequire software configuration. Users can immediately use
most of the features of this product simply by attaching the cables and turning the
power on.
3.1.1 Desktop Installation
For desktop installation, the switch needs to put on a clean, flat desk or table
close to a power outlet. Plug inall network connections and the power cord,
then the system is ready.
When deciding where to put the switch, you must ensure:
It is accessible and cables can be connected easily.
Cabling is away from - Sources of electrical noise such as radio,
transmitters, broadband amplifiers,and fluorescent lighting fixtures.
Water or moisture cannot enter the unit.
Air flow around the unit and through the vents in the side of the case is
not restricted(company recommend thatyou provide a minimumof
25mm clearance).
To prolong the operational life of your units:
Never stack units more than eight sets high if freestanding.
Do not place objects on top of any unit or stack.
Do not obstruct any vents at the sides of the case.
3.1.2 Rack-Mount Installation
The switch may standalone, or may be mounted in a standard 19-inch
equipment rack. Rack mounting produces an orderly installation when you
have a number of related network devices. The switch is supplied with two
mounting brackets and screws. These are used for rack mounting the unit.

10
Rack Mounting the Switch
The switch should be able to fitin the 19-inch rack.
1. Disconnect all cables from the switch before continuing.
2. Place the unit on a hard, flat surface with the front facing toward you.
3. Locate a mounting bracket over the mounting holes on one side of the unit.
4. Insert the screws and fully tighten with a suitable screwdriver.
5. Repeat the two previous steps for the other side of the unit.
6. Insert the unit into the 19-inch rack and secure with screws (not provided).
7. Reconnect all cables.
3.1.3 Installing Network Cables
After placing the switch on the desktop, we need to know how to connect the
device to network.
3.1.3.1 Station Connections with Twisted-Pair Cable
Connect each station to the switch by a category 5 twisted-pair cable
(straight or cross-over cable). Plug one RJ-45 connector into a
front-panel port of the switch, and plug the other RJ-45 connectorinto
the station’s network adapter.
3.1.3.2 Switch to Switch Connections with Twisted-Pair Cable
In making a switch to switch connection, you could use any Gigabit
port to connect another switch with straight or crossover cable.
As all ports support auto MDI-X function, the connection is
independent of cable type and allows using a straight cable to make a
switch to switch connection.

4. Switch Operation
4.1 MAC Address Table and Learning
The switch is implemented with a MAC address table, which is composed of many
entries. Each entry is used to store the address information of network nodes on the
network, including MAC address, port ID, etc. The information is the most important
base to do packet filtering and forwarding.
When one packet comes in from any port, the switch will learn the source address,
port ID, and the other related information in address table. Therefore, the content of
the MAC table will update dynamically.
4.2 Filtering and Forwarding
When one packet comes in from any portof the switch, it will check the destination
address besides the source address learning.The switch will look up the address
table for the destination address. Ifnot found, this packet will be forwarded to all the
other ports except theport where the packet comes in. If found, and the destination
address is located at different port from this packet comes in, the packet will be
forwarded to the port where this destination address is located according to the
information ofaddress table. But, if the destination address is locatedat the same
port as this packet comes in, this packet will be filtered.
4.3 Store and Forward
Store-and-forward is one kind of packet-forwarding methodology.As a
store-and-forward switch, it will store the complete packet in the internal buffer and
do the complete error checking beforetransmitting to the network.Therefore, no
error packets will disturb the network. It is the best choice when a network needs
efficiency and stability.
