1. Introduction
The KGS-0820 is a managed Gigabit Ethernet switch which is featured with the following switched ports and
advantages in a small footprint box:
Six 10/100/1000Mbps Gigabit copper ports
One combo port - 10/100/1000Mbps copper & 100Base-X SFP
One combo port - 10/100/1000Mbps copper & 1000Base-X SFP
Model Definition
Model Description Management Power over Ethernet Power Input
KGS-0820-P PoE_AC Managed Yes AC 100 ~ 240V
KGS-0820-D PoE_DC Managed Yes DC 44 ~ 54V
KGS-0820-S Standard Managed No AC 100 ~ 240V
KGS-0820-L Light Unmanaged No AC 100 ~ 240V
KGS-0820-LP Light_PoE Unmanaged Yes AC 100 ~ 240V
Plug and Play
The switch is shipped with factory default configuration which behaves like an unmanaged Gigabit switch for
workgroup. It provides eight 10/100/1000Mbps copper ports for connections to Ethernet, Fast Ethernet, and
Gigabit Ethernet devices. With the featured auto-negotiation function, the switch can detect and configure the
connection speed and duplex automatically. The switch also provides auto MDI/MDI-X function, which can
detect the connected cable and switch the transmission wire pair and receiving pair automatically. This
auto-crossover function can simplify the type of network cables used.
Fiber Connectivity
Two combo ports provide one 100M SFP slot and 1000M SFP slot, which can be installed with optional SFP
optical fiber transceivers to support one Fast Ethernet 100Base-FX and Gigabit 1000Base-X fiber connections
respectively when needed.

Management
The switch is embedded with an Http server which provides management functions for advanced network
functions including Port Control, Quality of Service, and Virtual LAN functions. The management can be
performed via Web browser based interface over TCP/IP network. The switch also provides SNMP agent to
support management from an SNMP manager.
Quality of Service
For advanced application, the switch is featured with powerful Quality of Service (QoS) function which can
classify the priority for received network frames based on the ingress port and frame contents. Furthermore,
many service priority policies can be configured for egress operation in per-port basis.
Virtual LAN (VLAN)
For increasing Tagged VLAN applications, the switch is also featured with powerful VLAN function to fulfill
the up-to-date VLAN requirements. The switch supports both port-based VLAN and tagged VLAN in per-port
basis.
802.1x Authentication
IEEE 802.1X port-based network access control function provide a means of authenticating and authorizing
devices attached to the switched port that has point-to-point connection characteristics, and of preventing
access to that port in cases in which the authentication and authorization process fails.
Power over Ethernet Option
For PoE applications, the models with PoE option provide eight IEEE 802.3af-compliant PoE PSE ports in all
copper ports. Each PSE port can deliver +48VDC power to one PoE PD (Powered Device) via the connected
Cat.5 cable.
AC & DC Power Options
In addition to standard AC power input, the switches provide DC options for applications with DC power
system.

2.6 Reset Button
The reset button is used to perform a reset to the switch. It is not used in normal cases and can be used for
diagnostic purpose. If any network hanging problem is suspected, it is useful to push the button to reset the
switch without turning off the power. Check whether the network is recovered.
The button can also be used to restore the software configuration settings to factory default values. The
operations are:
Operation Function
Press the button more than 4seconds when power up Restore factory default settings
Press the button and release during switch operation Reboot the switch
2.7 Making UTP Connections
The 10/100/1000 RJ-45 copper ports support the following connection types and distances:
Network Cables
10BASE-T: 2-pair UTP Cat. 3, 4, 5, EIA/TIA-568B 100-ohm
100BASE-TX: 2-pair UTP Cat. 5, EIA/TIA-568B 100-ohm
1000BASE-T: 4-pair UTP Cat. 5 or higher (Cat.5e is recommended), EIA/TIA-568B 100-ohm
Link distance: Up to 100 meters
Auto MDI/MDI-X Function
This function allows the port to auto-detect the twisted-pair signals and adapts itself to form a valid MDI to
MDI-X connection with the remote connected device automatically. No matter a straight through cable or
crossover cable are connected, the ports can sense the receiving pair automatically and configure themselves to
match the rule for MDI to MDI-X connection. It simplifies the cable installation.
Auto-negotiation Function
The ports are featured with auto-negotiation function and full capability to support connection to any Ethernet
devices. The port performs a negotiation process for the speed and duplex configuration with the connected
device automatically when each time a link is being established. If the connected device is also
auto-negotiation capable, both devices will come out the best configuration after negotiation process. If the
connected device is incapable in auto-negotiation, the switch will sense the speed and use half duplex for the
connection.
Port Configuration Management
For making proper connection to an auto-negotiation INCAPABLE device, it is suggested to use port control

function via software management to set forced mode and specify speed and duplex mode which match the
configuration used by the connected device.
2.8 Making Fiber Connection
The SFP slot must be installed with an SFP fiber transceiver for making fiber connection. Your switch may
come with some SFP transceivers pre-installed when it is shipped.
Installing SFP Fiber Transceiver
To install an SFP fiber transceiver into SFP slot, the steps are:
1. Turn off the power to the switch.
2. Insert the SFP fiber transceiver into the SFP slot. Normally, a bail is provided for every SFP transceiver.
Hold the bail and make insertion.
3. Until the SFP transceiver is seated securely in the slot, place the bail in lock position.
Connecting Fiber Cables
LC connectors are commonly equipped on most SFP transceiver modules. Identify TX and RX connector
before making cable connection. The following figure illustrates a connection example between two fiber
ports:
Make sure the Rx-to-Tx connection rule is followed on the both ends of the fiber cable.
Network Cables
Multimode (MMF) - 50/125μm, 62.5/125 μm
Single mode (SMF) - 9/125 μm
Fiber Port Configuration
For 100M fiber application on Port 7, use 100M_Full port configuration for fiber connection.
For 1000M fiber application on Port 8, just leave the default port configuration Auto for fiber connection.

2.9 Making PoE Connections
This section describes how to make a connection between a PSE port and a PoE PD device. In the models with
PoE function option, all copper ports are equipped with PoE PSE function. The ports are enabled to deliver
power together with network signal to a connected powered device via Cat.5 cable.
To make a PoE connection, the following check points should be noted:
1. For safety reason, the connected PoE PD (Powered Device) must be a IEEE 802.3af-compliant device.
Incompliant devices are not supported by the PoE switch model.
2. The Cat.5 cables used for the connections must be 4-pair cables. The power is sent over the spare pairs (4,5)
(7,8) of the cable. The maximum distance supported is 100 meters.
3. The power voltage supplied to the switch must be within the following range to make PoE function
working.
The PSE ports are equipped with the following capabilities:
1. Detection for an IEEE 802.3af compliant PD.
2. No power is supplied to a device which is classified non-IEEE 802.3af compliant PD.
3. No power is supplied when no connection exists on the port.
4. The power is cut off immediately from powering condition when a disconnection occurs.
5. The power is cut off immediately from powering condition when overload occurs.
6. The power is cut off immediately from powering condition when over-current occurs.
7. The power is cut off immediately from powering condition when short circuit condition occurs.
