The DC terminal block on the LBH100H is located on the left side of the unit and is equipped with three (3) screw-down lead posts.
BLACK BOX® Media Converter Switches Installation and User Guide The connection procedure is straightforward. Simply insert the DC leads to the LBH100H’s power terminals, positive (+) and negative (-) screws. The use of Ground (GND) optional; it connects to the LBH100H chassis. Ensure that each lead is securely tightened from the top, as shown here. NOTE: Always use a voltmeter to measure the voltage of the incoming power supply and figure out the +ve potential lead or -ve potential lead.
BLACK BOX® Media Converter Switches Installation and User Guide TX connections. When the ports are used as 10BASE-T ports, CAT 3 may be used. In either case, the maximum distance for unshielded twisted pair cabling is 100 meters (328 ft). For fiber port 10BASE-FL or 100BASE-FX multi-mode, 50/125 or 62.5/125 microns cabling can be used, whereas for single-mode, 9/125 microns cabling should be used. Fiber cabling supports much longer cable distance and higher bandwidths as compared to copper wiring.
BLACK BOX® Media Converter Switches Installation and User Guide 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. Note that the auto-cross function does not operate, if the port is fixed or not supporting auto-negotiation. 3.8.

BLACK BOX® 4.0 Media Converter Switches Installation and User Guide OPERATION 4.1 Dual-Speed Functionality, and Switching The LBH100A and LBH110A Series Media Converter Switches 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. (See Section 2.2).
BLACK BOX® Media Converter Switches Installation and User Guide Switching, Filtering and Forwarding Each time a packet arrives on one of the switched ports, the decision is taken to either filter or to forward the packet. Packets whose source and destination addresses on the same port segment will be filtered, constraining them to one port and relieving the rest of the network from processing them.
BLACK BOX® Media Converter Switches Installation and User Guide Switching, Address Learning The LBH100A and LBH110A Series units have address table capacity of 2K node addresses, and are suitable for use in large networks. They are self-learning, so that as nodes are added or removed or moved from one segment to another, the LBH100- and LBH110- Series switch automatically keeps up with node locations.
