Black Box LGB304A 4-Port Unmanaged Gigabit Switch

Description

The Black Box LGB304A is a 4-port unmanaged Gigabit Ethernet switch designed for small workgroups and home offices requiring easy network expansion . Each of the four RJ45 ports supports 10/100/1000 Mbps speeds with 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 using a store-and-forward switching method with a MAC address table supporting 1,000 entries . Forwarding rates are 14,880 pps for 10 Mbps, 148,800 pps for 100 Mbps, and 1,488,000 pps for 1000 Mbps. LED indicators provide clear status of power, link, and 1000M activity. The compact dimensions of just 0.8″H x 2.4″W x 3.1″D (20 x 62 x 79 mm) and weight of 0.4 lb (200 g) make it ideal for space-constrained deployments . The switch meets IEEE 802.3, 802.3u, 802.3ab, and 802.3x standards, is FCC and CE certified, and includes a US AC power adapter . This unmanaged switch requires no configuration, making it perfect for simple network expansion in small offices, home offices, and temporary workgroups.
