Keep edge networks simple without giving up the power delivery needed for modern devices. The Black Box LIE401A is an unmanaged PoE+ switch with 4 10/100/1,000 RJ45 ports and 1 SFP uplink, giving small installations a clean way to connect and power endpoints from a single device. This configuration is well suited to surveillance, access control, and distributed network edge deployments where teams want fast setup and minimal ongoing administration. PoE+ support reduces the need for separate power runs, while the SFP uplink provides a flexible path back to the core or aggregation layer. For buyers comparing entry-level switches, this model stands out by combining PoE+, gigabit copper access, and fiber uplink capability in one compact platform. That mix helps reduce cabling complexity and supports cleaner rack, wall, or enclosure builds. It is a practical fit when the goal is to power critical endpoints reliably while keeping the network footprint controlled.
