This eliminates propagation of bad packets, enabling all of the available bandwidth to be used for valid information. While other switching technologies such as "cut-through" or "express" impose minimal frame latency, they will also permit bad frames to propagate to the Ethernet network.
Black Box® Heavy Duty Edge Switches Installation and User Guide(07/05) (Many other switches have their packet buffer storage space divided evenly across all ports, resulting in a small, fixed number of packets to be stored per port. When the port buffer fills up, dropped packets result.
Black Box® Heavy Duty Edge Switches Installation and User Guide(07/05) Another feature implemented in Heavy-Duty LBHXXX Edge Switches is a collision-based flow-control mechanism (when operating at half-duplex only). When the Switch detects that its free buffer queue space is low, the Switch prevents more frames from entering by forcing a collision signal on all receiving half-duplex ports in order to stop incoming traffic.
Black Box® Heavy Duty Edge Switches Installation and User Guide(07/05) 2.4 Features and Benefits Full 100Mb or 10 Mb switching services for high performance Ethernet Black Box Heavy-Duty LBHXXX Switches provide Fast Ethernet switching on all ports.

Black Box® Heavy Duty Edge Switches Installation and User Guide(07/05) distance for unshielded twisted pair cabling is 100 meters (328 ft). For fiber port 10BASEFL 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® Heavy Duty Edge Switches Installation and User Guide(07/05) 3.8.1 Connecting Twisted Pair (RJ-45, CAT 3 or CAT 5, Unshielded or Shielded) The following procedure describes how to connect a 10BASE-T or 100BASE-TX twisted pair segment to the RJ-45 port. The procedure is the same for both unshielded and shielded twisted pair cables. 1. 2. 3. 4. 3.8.2 Using standard twisted pair media, insert either end of the cable with a RJ-45 plug into the RJ-45 connector of the port.
Black Box® Heavy Duty Edge Switches Installation and User Guide(07/05) 1. Before connecting the fiber optic cable, remove the protective dust caps from the tips of the fiber connectors.

Black Box® Heavy Duty Edge Switches 4.0 Installation and User Guide(07/05) OPERATION 4.1 Dual-Speed Functionality, and Switching The Black Box Heavy-Duty LBHXXX Edge Switches provide SIX switched ports with combination of fiber and copper or copper only. 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 4.2).
Black Box® Heavy Duty Edge Switches Installation and User Guide(07/05) 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 lie 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® Heavy Duty Edge Switches Installation and User Guide(07/05) 4.2 Auto-cross (MDIX), Auto-negotiation and Speed-sensing The RJ-45 ports independently support auto-cross (MDI or MDIX) in autonegotiation mode and will work properly with all the other connected devices with RJ45 port whether it supports Auto-negotiation or not (e.g 10Mb Hub) or fixed mode at 10Mb or 100Mb Half/Full Duplex(managed switch).
