Introduction
Chapter 1. Introduction
1.1 Welcome
Welcome and thank you for purchasing this "world class" product from CTC Union. We hope this product is everything
you wanted and more. Our Product Managers and R&D team have placed a "quality first" motto in our development
of this series of Gigabit Ethernet switches with the desire of providing a highly stable and reliable product that will give
years of trouble free operation.
In this chapter we will introduce this series, for Gigabit Ethernet applications. Chapter 2 will describe the panels and
LED indicators. All the models in this series utilize almost identical management interfaces, whether Console, Telnet,
SSH, HTTP (Web GUI) or SNMP (Simple Network Management Protocol). Chapter 3 will cover the basic operation using
Console or Telnet CLI. Chapter 4 will detail all of the configuration settings by using an easy to point and click Web
interface which can be accessed from any available web browser.
1.2 Product Description
GSW-3208M2 is a Managed Gigabit Ethernet switch designed to make conversion between 8-Port 10/100/1000Base-T
RJ-45 and 2 port 100/1000Base-X fiber optics with SFP optical modules. Traditionally, transmission distance of Gigabit
Ethernet over fiber interface can be extended from 550m to 100km using the flexibility of any third party pluggable
SFP modules. GSW-3208M2 is fully compliant with IEEE 802.3, 802.3u, 802.3ab and 802.3z standards. End-users can
simply connect their devices, such as Ethernet home gateway, wireless access point or NIC on PC/laptop via
10/100/1000Base-T twisted pair to the RJ-45 ports of the CPE switch. No Ethernet crossover cables are required and
link status can be easily monitored from the comprehensive LED display.
When GSW-3208M2 is deployed as a stand-alone solution, it incorporates an easy to use Web user interface for
operation, administration and maintenance both local and remotely. All of the enabled Layer 2 features and functions
of GSW-3208M2 can be configured and monitored via web interface and SNMP management. GSW-3208M2 is the
most suitable solution for deploying and provisioning the FTTX service of operators or service providers.

Panels & LED Indicators
2.1.1 LAN Connections
There are 8 shielded RJ-45 that provide LAN connections from GSW-3208M2 Switch. These ports support Ethernet speeds
of 10/100/1000M automatically. Each of these eight LAN ports has associated LEDs, located on the front panel, which
indicate the active link state and the detected speed of the interface. A green indicates a link and a speed of 10/100M,
while orange color indicates a link and speed of 1000M.
2.1.2 Fiber Connections
Refer to the graphic drawing above. GSW-3208M2 utilizes an SFP module for fiber transmission. The fiber port has an
associated status LED to indicate the presence or absence of fiber link and will also flash when there is Ethernet activity
on the port. The SFP cage may insert any standard SFP module and be configured for 100M or 1000M operation. There is
no 'lock out' mechanism, so any third party SFP, compliant with MSA, can be used in GSW-3208M2.
2.1.3 Console Connection
The D-Sub 9 is an RS-232 console terminal port for local management. Connect one end of the provided DB-9 cable to the
device, the other end to your local PC. Pinouts for RS-232 DB-9 (Figure 3) connector are illustrated below.
2.1.4 Reset Push-Button
There is a recessed push-button switch used to reset GSW-3208M2 or to return it to factory defaults. Pressing the reset
momentarily once will "warm boot" the switch. Pressing and holding the pushbutton switch for more than 3 seconds and
then releasing will set the running configuration to the original factory default settings, including the original factory
default IP address followed by a "warm boot". If the IP address of the switch is unknown, it may be necessary to do a
factory default reset. The IP address will then be the known default.
2.1.5 Power
GSW-3208M2 provides two power options for power input. When AC power module is available, AC power is supplied to
GSW-3208M2 through a standard IEC C14 3-prong receptacle, located on the front panel. Any national power cord with
IEC C13 line plug may be used to connect AC power to the power module. With a DC48 power module, DC voltage is
connected to the terminal block. GSW-3208M2 should always be grounded through the protective earth lead of the
power cable in AC installations, or via the frame ground connection for DC installations.

2.1.6 Earth Grounding
An earth ground hole (next to AC or DC power supply) is provided on the left side of the front panel with an earth ground
sign next to it. Grounding the device can help to release leakage of electricity to the earth safely so as to reduce injuries
from electromagnetic interference (EMI).
Prior to connecting to the power, it is important to connect the ground wire to the earth. Follow steps below to install
ground wire:
Step 1. Prepare one suitable ground screw and one grounding cable.
Step 2. Attach the grounding screw to the ring terminal of the grounding cable. Make sure that the grounding cable is
long enough to reach the earth.
Step 3. Use a screwdriver (or other tools) to fasten the grounding screw on the earth ground hole securely.
2.2 LED Indicators
LED indicators are located on the front panel of the unit. Each port has a corresponding LED indicator that provides a
visual and real-time indication of the current operating state. A description of these LED indicators is provided below.

Introduction to CLI
Chapter 3. Introduction to CLI
3.1 Introduction
The GSW-3208M2 Managed Gigabit Ethernet switch provides a number of configuration/management methods. The first
method of configuration/management uses a command line interface (CLI) via Console/Telnet/SSH access and is familiar
to most network engineers. This requires that networking be configured so that the device can be accessed via a LAN port.
Accessing the GSW-3208M2 from a network allows for both local and remote management.
For engineers that are not comfortable using CLI, this device should be managed using any standard Web Browser in a
more user friendly 'point-and-click' method. Therefore, in most configuration scenarios, Console/Telnet/SSH will only be
used by experienced networking engineers.
After the device has been properly configured for the application and placed into service, a third method of
configuration/management can be employed using Simple Network Management Protocol (SNMP). The operator will use
SNMP management software to manage and monitor the GSW-3208M2 switches on a network. This requires some
configuration of the device to allow SNMP management. In addition, the network management platform will need to
import and compile the proprietary MIB (management information base) file so that the management software knows
"how" to manage the GSW-3208M2.
3.2 Console Operation
Using the provided accessory cable, connect the "CONSOLE" port to the PC terminal communications port (DB9). Run any
terminal emulation program (HyperTerminal, PuTTY, TeraTerm Pro, etc.) and configure the communication parameters as
follows:
Speed: 115,200
Data: 8 bits
Parity: none
Stop bits: 1
Flow Control: None
From a cold start, the following screen will be displayed. At the "Username" prompt, enter 'admin' with no password.
3.3 Telnet Operation
Default TCP/IP settings of GSW-3208M2:
IP Address: 192.168.0.1
Subnet Mask: 255.255.255.0
