Linksys rackmount switch delivers non-blocking, wire speed switching for your 10, 100, and 1000 megabit network clients, plus multiple options for connecting to your network backbone. Sixteen 10/100/1000 ports wire up your workstations, while the two mini GBIC ports allow future expansion to alternate transmission media like optical fiber for your backbone. All ports have automatic MDI/MDI-X crossover detection, so you dont have to worry about the cable type, and polarity detection will even automatically correct wiring errors. Each port independently and automatically negotiates for best speed and whether to run in half- or full-duplex mode. Head-of-line blocking prevention keeps your high-speed clients from bogging down in lower-speed traffic and fast store-and-forward switching prevents damaged packets from being passed on into the network.
