    This high-speed Gigabit Ethernet switch is ideal for building small workgroups as well as small- or home-office networks. It's also a good choice for remote- and branch-office installation.

    Its fast 1000-Mbps ports provide fast file transfer, yet automatically adapt to older 10- and 100-Mbps devices, enabling you to mix and match different network speeds on the same network. All ports support Auto MDI/MDI-X, so you never have to worry about whether you need a straight-pinned or crossover cable.
