Black Box LGB408A-R2 9" Gigabit Ethernet Switch, 8-Port

The LGB408A-R2 Black Box Switch provides eight 10-/100-/1000-Mbps RJ-45 ports. It was designed for easy installation and high performance in an environment where traffic on the network and the number of users increase continuously. With its Gigabit chipset, the 9" Gigabit Ethernet Switch can fully support the highest speed even when fully loaded and running in full-duplex mode. The switch also provides automatic crossover detection functionality on each port. It’s easy to uplink to another switch without a crossover cable. 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.

This quiet Black Box Switch operates without a fan. The compact rigid desktop size was specifically designed for Remote Office and Branch Office (ROBO), and medium to large workgroups. You can install the switch where space is limited. It provides smooth network migration and easy upgrades to network capacity. The 9" size can be rackmounted on a 10” or 19” cabinet.
