The TP-LINK TL-SG105E is easy to use and manage. Auto MDI/MDI-X crossover on all ports eliminate the need for crossover cables or uplink ports. Auto-negotiation 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. Its compact size makes it ideal for desktops with limited space while also being Rack-mountable, convenient and safe. Dynamic LED lights provide real-time work status display and basic fault diagnosis.
