Ethernet Switching Technology
Ethernet Switching Technology dramatically boosted the total
bandwidth of a network, eliminated congestion problems, and greatly
reduced unnecessary transmissions.
This revolutionized networking by allowing two-way, simultaneous
transmissions over the same port (Full-duplex) that essentially
doubled the bandwidth. Secondly, it reduced the collision domain to a
single switch-port that eliminated the need for carrier sensing.
This technology also uses a store-and-forward technology approach
of inspecting each packet to intercept corrupt or redundant data,
eliminating unnecessary transmissions that slow the network.
Ethernet Switching Technology supplies higher performance at lower
costs than other solutions. Due to wider bandwidth, no congestion,
and the reduction in traffic, switching is replacing expensive routers
and inefficient hubs as the ultimate networking solution.
Management Methods
The SmartGST-801M supports the following management methods:
nn
nn Console and Telnet Management
nn
nn Web-based Management
nn
nn SNMP Network Management
Console and Telnet Management
Console Management is done through the RS-232 Console Port.
Managing the SmartGST-801M with this method requires a direct
connection between a PC and the switch. Telnet management is
done over a network. Once the SmartGST-801M is on the network,
you can use Telnet to Log in and change the configuration.
Web-based Mana
g
ement
This switch provides an embedded HTML web site residing in flash
memory. It offers advanced management features and allows users
to manage the SmartGST-801M from anywhere on the network
through a standard browser such as Microsoft Internet Explorer.
SNMP Network Management
SNMP (Simple Network Management Protocol) provides
monitoring and control of network devices. It manages
configurations, statistic collection, performance, and security.

Hardware Description
This section describes the switch hardware. The SmartGST-801M is
a 19" rack mountable switch with eight 100Mbps Fiber ports and one
GBIC port
The physical dimensions of the SmartGST-801M are:
440mm x 160mm x 44mm (L x W x H)
Front Panel
The Front Panel of the SmartGST-801M consists of eight 100Mbps
Fast Ethernet Fiber and one GBIC port. LED indicators are located on
the front panel of the switch.
Figure 2-1. The Front Panel of theSmartGST-801M
The front panel of the switch is displayed as below. There are 2 types
of fiber connectors available. These fiber connectors are SC or ST
Multi-mode and SC Single Mode.
Console Port: Console management can be done via the Console
Port. It requires a direct connection between the switch and an end
station (PC) via an RS-232 cable.
SmartGST-801M
Figure 2-2. The Front Panel of the SmartGST-801M
n100Base-FX Fiber Port: There are three types of fiber
connectors available for the SmartGST-801M. The distance
for fiber cabling can be extended up to 2 kilometers with SC
or ST Multi-Mode and up to 30 kilometers with SC Single
Mode.
nGBIC port: This GBIC slot supports 3.3V Gigabit
Transceivers for Gigabit SX or LX only.
LED Indicators
Figure 2-3. LED Indicators
There are three LED Indicators (LNK/ACT, FDX/COL) for each Fiber
port and one Power LED. The following table provides descriptions of
the LED statuses and meaning. They provide a real-time indication of
systematic operation status.

Rear Panel
The Console port and 3-pronged power plug is located at the Rear
Panel of the SmartGST-801M as shown in Figure 2-7. The Switches
will work with AC in the range 100-240V AC, 50-60Hz.
Figure 2-7 The Rear Panel of the SmartGST-801M
Desktop Installation
Set the switch on a sufficiently large flat space with a power outlet
nearby. The surface where you put your Switch should be clean,
smooth, level, and sturdy.
Make sure there is enough clearance around the Switch to allow
attachment of cables, power cord and air circulation.
Power on/off switch
AC Power Plug Socket
Attaching Rubber Feet
1. Make sure mounting surface on the bottom of the Switch is grease
and dust free.
2. Remove adhesive backing from your rubber feet.
3. Apply the rubber feet to each corner on the bottom of the Switch.
These footpads prevent the switch from shock and vibration.
Figure 2-8. Attaching Rubber Feet to each corner on the bottom of the Switch
Power On
Connect the power cord to the power socket on the rear panel of the
Switch. The other side of power cord connects to the power outlet.
The internal power supply in the Switch works with AC in the voltage
range 100-240VAC, frequency 50~60Hz.
Check the power indicator on the front panel to see if power is
properly supplied.

Network Application
This section provides a few samples of network topology in which the
SmartGST-801M is used. This switch is designed as a desktop or
segment switch.
Segment Application
In enterprise networks where large data broadcasts are constantly
processed, this switch is perfect for departmental connections to the
corporate backbone.
Figure 3-2 Segment Application
You can use the SmartGST-801M to connect PCs, workstations, and
servers to each other by connecting these devices directly to the
Switch. All the devices in this network can communicate with one
another. Connecting servers to the backbone switch allows other
users to access the server s data.
The SmartGST-801M automatically learns node addresses, which
filter, and forward all traffic based on the destination address. You
can use any of the Fiber ports to connect with another switch or hub
to interconnect each of your small switched workgroups to form a
larger and long distance switched network.
Figure 3-3 Use fiber ports to extend the distance between workgroups
In the above illustration, two SmartGST-801Ms are used to
interconnect two small workgroups. By using fiber ports to connect
switches, the distance between two switches via fiber cable can be
up to 30Km (using a SC Single Mode fiber connector).
4.
Network Configuration
This Section explains how to configure console management.
Console management involves the administration of the Switch using
a direct connection to the RS-232 console port. This port is a female
DB-9 connector. From the main menu of the console program, user
has access to the functions of the switch.
Connecting a Terminal or
PC to the Console Port
Use the supplied RS-232 cable to connect a terminal or PC to the
console port. The terminal or PC to be connected must support the
