Black Box Modular Switches Installation and User Guide (8/99) The RJ-45 ports run at 10/100Mbps with N-way auto-negotiation capability, whereas the fiber port runs at 100Mbps with half- or full-duplex capability manually selected. The default condition is full-duplex. Internal jumpers settings allow technicians to set the 100Mb fiber port to half-duplex mode. (See Section 3.4). On LE14XXA Combo 4-port modules, there are three LED’s for each RJ-45 port, which indicate stat

Black Box Modular Switches Installation and User Guide (8/99) LE14XXA-Series Switches are constantly adapting internally to provide maximum network performance with the least dropped packets. When the Switch detects that its free buffer queue space is low, the Switch sends industry standard (full-duplex only) PAUSE packets out to the devices sending packets to cause “flow control”. This tells the sending devices to temporarily stop sending traffic, which allows a traffic

Black Box Modular Switches Installation and User Guide (8/99) Example 2 : 8-port LE1408A In another application, a Switch is needed to provide a Fast Ethernet backbone. The backbone consists of four high-speed LAN segments, each operating over 100MB full-duplex fiber lines. In addition to interconnecting the fiber backbone segments in the network center, the Switch needs to provide high-speed switched support for two central servers, for a 100MB connection to a router
