The TL-SF1008D Fast Ethernet switch provides 8 auto-negotiation RJ45 ports at 10/100Mbps. All ports support Auto MDI/MDIX function, eliminating the need for crossover cables or uplink ports. With a non-blocking switching architecture, TL-SF1008D forwards and filters packets at maximum cable speed for maximum performance. With 2K Jumbo frame, the performance of large file transfers is significantly improved. And IEEE 802.3x flow control for Full Duplex mode and back pressure for Half Duplex mode relieve traffic congestion and make the TL-SF1008D work reliably.The automatic functions of this switch make installation plug and play and hassle-free. No configuration required. Auto MDI/MDIX eliminates the need for crossover wires. Auto-negotiation on each port detects the link speed of a network device (10, 100 Mbps) and intelligently adjusts for compatibility and optimal performance.
