Overview

The Black Box LGB304A is a compact gigabit Ethernet switch with four 10/100/1000 Mbps RJ45 ports. Typical applications include LAN connectivity for small workgroups. The switch is ideal for mobile teams such as auditors that require a small, portable switch to expand port counts. The switch can be powered from a USB port or from the included power adapter. The switch delivers line rate, non blocking throughput. Ports are autonegotiating half/full duplex and include LED indicators to view port status. This unmanaged switch is plug and play and does not require any configuration.
