BLACK BOX® Power Over Ethernet Switch(PoE) Media Twisted Pair (CAT 5) Twisted Pair (CAT 5) Installation and User Guide IEEE Standard 10BASE-T 100BASE-TX Connector RJ-45 RJ-45 NOTE : It is recommended that high quality CAT. 5 cables (which work for both 10 Mbps and 100Mbps) be used whenever possible in order to provide flexibility in a mixed-speed network, since P80-series switch ports are auto-sensing for either 10 and 100Mbps.
BLACK BOX® Power Over Ethernet Switch(PoE) Installation and User Guide 1. Using standard twisted pair media, insert either end of the cable with a RJ-45 plug into the RJ-45 connector of the port. Note that, even though the connector is shielded, either unshielded or shielded cables and wiring may be used. 2. Connect the other end of the cable to the corresponding device. 3.
BLACK BOX® Power Over Ethernet Switch(PoE) 4.0 Installation and User Guide OPERATION 4.1 Dual-Speed Functionality, and Switching The LP004A Series Power over Ethernet (PoE) Switch provide four switched ports (three ports in the front and one on the rear). The architecture supports a dual speed switching environment, with standard auto-negotiation capability. The switched RJ-45 ports are full- or half-duplex auto-sensing for mode and speed, and auto-cross for plug polarity.
BLACK BOX® Power Over Ethernet Switch(PoE) Installation and User Guide LP004A Series units are plug-and-play devices. There is no software configuring to be done at installation or for maintenance.
