About the Switch

The Switch, GSW-400S is designed to allow simultaneous transmission of
multiple packets via an internal high-speed data channel. This means that it
can partition a network more efficiently than bridges or routers in most
environments.
The Switch is equipped with Category 5 copper cable for uplinking to a
network backbone or network server. It is compatible with all 10Mbps,
100Mbps and 1000Mbps Ethernet environments. The increased speed and
extra bandwidth offered by Gigabit Ethernet will support faster and more
users applications with generating more traffic.
The Switch is designed for Plug and Play installation, allows the network

administrator to simply connect the network and power cables and the
Switching/bridging functions begin automatically.
The front panel of these Switches provides LEDs for easy recognition of the
switch operation status and for troubleshooting. These LEDs display the
power status for the system and link/ speed/ collision, full-duplex, transmit
and receive status for each port.
The built-in console interface can be used to configure the Switch’s setting for
Priority queuing, VLAN, and Port Trunk Groups, Port Monitoring and Port
Speed.

Hardware Description

This section describes the hardware features of these Switches. For easier
management and control of the switch, familiarize yourself with its display
indicators, and ports. Front panel illustrations in this chapter display the unit
LED indicators. Before connecting any network device to the hub, read this
chapter carefully.

Front Panel

The unit front panel provides a simple interface monitoring the switching hub.
It includes a power indicator for each port.

Rear Panel

The rear panel of the Switch indicates an AC inlet power socket, which accepts
input power from 100 to 240VAC, 50-60Hz. And a RS-232 console port for
setting up the switch via a connection to a console terminal or PC using a
terminal emulation program.

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 use an
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 hub from being damaged by unregulated surge or current to the Switch
or the power adapter.

Hardware Installation

Connecting End node or Hub or Switch

1. Place the Switch on a smooth surface or fasten the mounting brackets with

the provided screws in a standard 19” rack

2. Connect the DC jack of AC adapter to the DC inlet socket of Switch and the

other end into the local power source outlet

3. Connect hub or PC to one port of the Switch using Category 3/4/5 UTP/STP

cabling

4. Connect another hub or PC to the other port of Switch by following the

same process as described in Step3.

Figure 3. End node or Hub or Switch connection

Notice:

Cable distance for Switch

The cable distance between Ethernet Switch and hub/PC should
not exceed 100 meter.

Make sure the wiring is correct

It can be used Category 3/4/5 cable in 10 Mbps operation. To
reliably operate your network at 100Mbps and 1000Mbps, you
must use an Unshielded Twisted-Pair (UTP) Category 5 cable,
or better Data Grade cabling. While a Category 3 or 4 cable
may initially seem to work, it will soon cause data loss.

VLAN

Select :>> 2

Select :>>

Entry:

Select “2” from Main Menu.

Purpose:

Each port of the switch can be assigned to one or multiple VLANs (this
device can be divided into 4 VLANs maximum). Frames from the source
port will only be forwarded to destination ports within the same VLAN
domain. A broadcast/multicast frame will be forwarded to all ports
within the VLAN(s) of the source port except the source port itself. An
unicast frame will be forwarded to the destination port only if the
destination port is in the same VLAN as the source port. If the
destination port belongs to another VLAN, the frame will be discarded.
Each port should be assigned with a dedicated uplink port. Unicast
frames with unknown destination addresses will be forwarded to the
uplink port of the source port. An uplink port can either be a single port
or a trunk.

Default:

All ports assigned to one VLAN.

Purpose:

The uplink port provides a way to connect the switch with a repeater hub,
a workgroup switch, a router, or any type of interconnecting device
compliance with IEEE 802.3 standards. Switch will send all frames with
unmatched DA and multicast/broadcast frames to the uplink port. It is
very important that each port is assigned to an uplink port, or data frames
might be lost. The uplink port should be configured to be within the
same VLAN as the source port. If the uplink port is not a member of the
VLAN, the broadcast or multicast frames will not be forwarded to its
designated uplink port. Multiple VLANs can share the same uplink port.

Chapter 4

Switch Operation

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..

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.

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

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 existing
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.

28

Ethernet Smart Switch

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-TX and 1000Base-SX can only
connected Full-duplex mode.

Troubleshooting

This chapter contains information to help you solve problems. If Switch is not
functioning properly, make sure the Ethernet Switch was set up according to
instructions in this manual..

The Link LED is not lit

Solution:
Check the cable connection and remove duplex mode of the Switch

Some stations can not talk to other stations located on the other
port

Solution:
The address table may contain older information than of the address table of
that node. Please power down to refresh the address information.
