Chapter 1 Introduction of the Product
Thank you for choosing the TL-SG105/TL-SG108 5/8-port Gigabit
Desktop Switch.
1.1 Overview of the Product
Powered by the Gigabit Ethernet technology, TL-SG105/TL-SG108
Gigabit Desktop Switch provides the seamless network connection,
which can speed up your old network to 1000Mbps, ensuring the
graphics, CGI, CAD, or multimedia files and other applications with
bandwidth-intensive files transferred across the network almost instantly.
The non-blocking switching architecture adopted in the TL-SG105/
TL-SG108 switch greatly improves network response times as well as
significantly speed up the traffic between subnets by forwarding and
filtering packets at full wire-speed for maximum throughput.
The TL-SG105/TL-SG108 switch is plug-and-play. In addition, the Auto-
MDI/MDIX cable detection on all ports eliminates the demand of
crossover cable or Uplink port. Each port can be used as general ports
or Uplink ports, and any port can be simply plugged into a server, a hub,
a router, a switch or a PC, using the straight cable or crossover cable.
Diagnostic LEDs which display link status and activity, allowing you to
quickly detect and correct problems on the network.
The TL-SG105/TL-SG108 switch adopts Green Ethernet technology,
supports power saving features. The switch automatically powers down
the ports that have no link or are connected to the computers which
have been shut down, budgets power output for different Ethernet cable

Chapter 2 Identifying External Components
This chapter describes the front panel and rear panel of the switch.
2.1 Front Panel
Figure 2-1 TL-SG108 Switch Front Panel
The following parts are located on the front panel:
 Ports (1-8): The TL-SG108 switch is equipped with 8 10/100/
1000Mbps Auto-Sensing RJ45 ports where you will connect your
network devices. The working status can be indicated by the
corresponding LEDs on the panel.
 Power LED: This indicator will light up when the switch powers on.
 LEDs: Each 10/100/1000Mbps Auto-Sensing RJ45 port has two
corresponding LEDs.
The LED on the left side of the RJ45 port will light solid green when a
1000Mbps device is connected to the port. It flashes green when data is
being transmitted or received on the working connection.
The LED on the right side will light solid yellow when a 10/100Mbps
device is connected to the port. It flashes yellow when data is being
transmitted or received on the working connection.
The LEDs’ description above explains the device’s working status after

2.2 Rear Panel
Figure 2-2 TL-SG108 Switch Rear Panel
The following parts are located on the rear panel:
 Kensington Security Slot: The switch provides one security slot.
 Power socket: The power socket, located at the right side of the
rear panel, is where you will connect the power adapter. Please
use the power adapter provided with the TL-SG108 switch.
Chapter 3 Installation
The switch can be either located on a desktop or mounted on a wall.
3.1 Mounting the Switch on a Desk
To locate the switch on a desktop, please follow these steps:
1) Place the switch on a flat desk.
2) Inspect the Power Adapter carefully and make sure that it is
properly connected to a power source.
3) Ensure adequate ventilation space around the switch for
dissipating heat and air.
Please avoid any heavy thing placed on the switch.
Page: 10
To ensure the stable cable connection, please keep the switch
horizontal on the desktop, with white cover facing up.
3.2 Mounting the Switch on a Wall
There are two wall-mounting slots on the bottom panel of the switch. To
mount the switch on a wall, please follow the steps below.
1) Drill two holes into the wall. Insert a screw into each hole and
leave a part of its head exposed.
2) Place the two wall-mounting slots over the screws and slide the
switch down to fasten it.

Appendix B: Troubleshooting
1. The Power LED is not lit
Check to see if the AC power cord is connected to the switch
properly, and make sure the power source is ON.
2. The Link/Act LED is not lit when a device is connected to the
corresponding port
Check to see if the cable connectors are firmly plugged into the
switch and the device, and verify the connected device is turned on
and working well. Make sure the cable is not longer than 100
meters (328 feet).
