Black Box LGB304AE 4-Port USB-Powered Gigabit Switch

Description

The Black Box LGB304AE is a compact 4-port Gigabit Ethernet switch designed for mobile professionals and small workgroups requiring easy network expansion without needing a spare power outlet . Each of the four 10/100/1000 Mbps RJ45 ports features auto-negotiation for half/full-duplex operation and Auto MDI/MDI-X, eliminating the need for crossover cables. The switch delivers line-rate, non-blocking throughput and uses a store-and-forward switching method with a MAC address table supporting 1,000 entries . A key feature is its flexible power options – the switch can be powered directly from a computer’s USB port via the included USB power cable, or from the included 100-240 VAC external power supply (output 5 VDC, 1.2 amps) . Easy-to-see LED indicators show power, link, and 1000M activity status. This unmanaged switch is true plug-and-play, requiring no configuration, making it ideal for mobile teams such as auditors who need a portable switch to expand port counts in temporary workspaces.
