Gigabit Switch
Featured 10/100/1000Mbps ports, TL-SG105 and TL-SG108 greatly expands your network
capacity, enabling instant large les transferring. So, power users in the home, oce, work-
group, or creative production environment can now move large, bandwidth-intensive les
faster. Transfer graphics, CGI, CAD, or multimedia les across the network instantly.
Go Green With Your Ethernet
You now have the choice to go green when upgrading to a gigabit network! This new genera-
tion TL-SG105 and TL-SG108 feature the latest innovative energy-ecient technologies that
can greatly expand your network capacity with much less power. It automatically adjusts
power consumption according to the link status and cable length to limit the carbon footprint
of your network.
Power down Idle Ports
When a computer or network equipment is o, the corresponding port of a traditional switch
will continue to consume considerable amounts of power. TL-SG105 and TL-SG108 can
automatically detect the link status of each port and reduce the power consumption of ports
that are idle, resulting in up to reduction in power use.
Power Budget According to Cable Length
Ideally, shorter cable would use less power because of less power degradation over their
length; this is not the case with most devices as they will use the same amount of power
across the cable regardless of the length.

Trac Optimization
802.1p and DSCP QoS enable smooth latency-sensitive trac such as voice and video, and
IGMP Snooping optimizes the Multicast data stream.
Easy to Use
The auto features of this gigabit switch make installation plug and play and hassle-free. No
conguring is required. Auto MDI/MDIX eliminate the need for crossover cables. Auto-negotia-
tion on each port senses the link speed of a network device (either 10, 100, or 1000 Mbps) and
intelligently adjusts for compatibility and optimal performance.
