Chapter 1. Introduction of the Product
Thank you for choosing the TL-SG1008D 8-port Gigabit Desktop Switch.
1.1 Overview of the Product
Powered by the Gigabit Ethernet Technology, the TL-SG1008D 8-port Gigabit Desktop Switch
provides the seamless network connection, which can speed up your old network to 1000Mbps.
The increased speed and backbone connections make Gigabit a reality, which ensures 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-SG1008D 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-SG1008D switch is compatible with all 10Mbps, 100Mbps, and 1000Mbps Ethernet
devices, which can protect your existing network investments while provide you a straightforward
migration path to faster Gigabit speed.
The TL-SG1008D switch is very easy to manage since it is plug-and-play and no configuration is
needed. In addition, the auto MDI/MDI-X 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 or a switch, 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.
1.2 Convention
The Switch or TL-SG1008D mentioned in this User Guide stands for TL-SG1008D 8-port
Gigabit Desktop Switch without any explanation.

¾4K entry MAC address table of the TL-SG1008D with auto-learning and auto-aging
¾Support for Jumbo frames of up to 9728 Bytes
¾LED indicators for monitoring power, link, speed and activity
¾External power adapter supply
Chapter 2. Installation
2.1 Mounting the Switch on a Desk
To install the Switch, please follow the steps:
1) You can place the Switch on a flat desk.
2) Please 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.
)Note:
Please avoid any heavy thing placed on the switch.
2.2 Power On
TL-SG1008D 8-port Gigabit Desktop Switch can be used with AC power supply. Powering on the
Switch, it will automatically initialize and its LED indicators will respond as follows:
1) All the 10/100Mbps and 1000Mbps Link/Act LED indicators will light simultaneously at first,
then light in turn and the 10/100Mbps Link/Act LED indicators will light simultaneously again
for the last time, which indicates the system initialized well.
2) The Power indicator will light all the time.
)Note:
If the LED indicators don’t respond as described above, please check the power supply and its
connection.

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).
