Part One Hardware Installation Guide
Chapter 1 Product Instruction
1.1 Introduction
1) GGM GS26L2 is Full Gigabit L2 Managed Switch
Please read through this User Guide before operating the GGM GS26L2 L2
Managed Switches.
1.2 Front Panel
1. GGM GS26L2
24*10/100/1000M Base-T ports, 2*1000 Base-X SFP; 1*Console port .
GGM GS26L2 Front Panel
LED Indicator Instruction
Please check the LED indicators on the left of front panel.
1) System Indicator
The System indicator is on the upper-left side of front panel, it is on when the switch
is powered. The indicator is on when switch works normally.
2) Power Indicator
Below the System indicator is the power indicator, the indicator is on when switch
works normally. If the indicator is off, please check the power supply.
3) 10/100Mbps Link/ACT Indicators
The indicators marked with numbers are yellow when the 10/100M ports
auto-negotiate connected, and the yellow indicators flash when there are data
communications through the ports.
4) 1000Mbps Link/ACT Indicators
The indicators marked with numbers are green when the 1000Mbps ports
GIGAMEDIA User’s Guide_V2.0.7
Page 6 of 35
auto-negotiate connected, and the green indicators will flash when there are data
communications through the ports.
1.3 Rear Panel
Rear Panel
Power Socket: Three-core power socket is adopted, please connect female head
of power cord to the socket, and connect the AC power supply with male head.
Chapter 2 Preparations before Instruction
2.1 Precautions
Please read the following precautions carefully before operation, to avoid damaging the
device or causing body injuries.
1). Please remove the power socket before cleaning the switch. Don’ wipe the switch with wet
cloth or wash the switch with liquid.
2). Don’t stock the device in damp environment or near water, to avoid water or moisture
penetrating into the inner device.
3). Don’t put the device on a unstable box or desk, the device will get damaged from falling.
4). Please keep good ventilation indoor, and make sure the heat dissipation function of switch
works well.
5). The switch only works normally in suitable voltage. Please check the working voltage first.
6). Please don’t open the switch enclosure randomly, especially when the switch is powered
on, there is risk of electric shock.
7). Please wear anti-static wrist strap when change the interface board, to avoid the static
electricity damage the board.
2.2 Check Installation Environment
The switch is for indoor use only, please pay attention to the following problems when install
the switch in a cabinet or put the device directly on the desktop.
1) The air vents of switch must have enough space to dissipate the heat inside enclosure.
2) A good heat dissipation system in the cabinet or on the desktop.
3) The cabinet or desktop strong enough to support the weight of switch and installation
accessories.
4) Safe ground connection for the cabinet or desktop.
2.3 Installation Tools
1) Flathead screw driver
GIGAMEDIA User’s Guide_V2.0.7
Page 7 of 35
2) Cross screw driver
3) Anti-static wrist strap
Chapter 3 Installation
3.1 Install the Switch
3.1.1 Install the switch on a 19 inch standard cabinet
1) First fix the provided two L-shaped brackets on the two sides of switch.
2) Fix the switch on the rack with screws (screws are not provided).
Cabinet Installation
3.1.2 Install the switch on the desktop
When there is no 19 inch standard cabinet, the switch is usually put on clean desktop. The
operation is easier, please follow the below instructions:
1) Keep the desktop stable and safely grounded.
2) Set aside 10cm space around switch for heat dissipation.
3) Don’t put any heavy device on the switch.
3.2 Connect the power cord and grounded cord
3.2.1 Select of AC Power Socket
The neutral one-phase 3-wire power socket is advised to adopt, or the multifunctional PC
power socket. The neutral point of power supply must be well grounded, please check the
grounded power supply before operation.
one-phase 3-wire power socket

Page 8 of 35
3.2.2 Connection of AC power cord
Step one: please connect one end of power cord to the power jack on the switch rear panel,
Connect the other end to the AC power socket.
Step two: check the power indicator (PWR) on the front panel, if the LED is on, connection is
successful.
3.3 Test after Installation
Make sure the working voltage is the same with the rated voltage of switch.
Check the connection of grounded cord.
Check the connection of configuration cable and power input cord.
If the interface cable is partly deployed outdoor, please check the connection of anti-thunder
AC power strip and interface anti-thunder device .
