BLACK BOX→ Power Over Ethernet Switch(PoE) Installation and User Guide
they provide power only to 802.3af, PoE end devices only. PoE is managed by a multi-
stage handshake to protect equipment from damage and to manage power budgets
.The LP004A ports will discontinue supplying power when the PoE powered devices are disconnected, and support the 802.3af PoE PSE standard for over-current protection, under-current detection and fault protection.
The LP004A provides a standards-compliant way to power and connect a few small Ethernet devices at the edge of a network where AC power is not cost-effective to deploy. Since PoE is rapidly emerging as an Ethernet option in industrial, commercial, outdoor and military applications, the Black Box LP004A enables the efficient deployment of reliable VoIP and wireless access networking devices to increase the efficiency of heavy duty industrial communications. Using PoE switches like the Black Box LP004A can produce significant cost savings as well as flexibility and reliability advantages over traditional AC- powered devices. The simplicity of PoE increases reliability and reduces the overall cost of installation and operation.
