The FX82051MSTR2 unmanaged Ethernet switch provides five 10Base-T/ 100Base-TX ports and one 100Base-FX fiber port for the transport of bidirectional Ethernet data. Two fibers are required to transport bidirectional data over the fiber port. Available in multimode and single-mode versions, the FX82051MSTR2 switch is designed for point-topoint applications. The fiber port on the FX82051MSTR2 switch is forced to full-duplex 100 Mbps operation. Networking functions for each of the five 10Base-T/100Base-TX ports (RJ-45 twisted-pair copper ports) are user-selectable by means of a rotary switch. Autonegotiation allows a 10Base-T/100Base-TX port to automatically negotiate between 10 Mbps and 100 Mbps data rates and between full-duplex and halfduplex modes. If autonegotiation is not desired, a port can be forced to specific modes of operation: 10 Mbps or 100 Mbps data rate, halfduplex or full-duplex mode, and the enabling/disabling of flow control. The auto MDI/MDI-X feature allows each RJ-45 port to connect to either a straight-through or crossover RJ-45 cable. Modular in design, the FX82051MSTR2 unit can be rack mounted or can be used as a stand-alone module. Rack mounting is accomplished using the RK5000 Series rack mount chassis. As a stand-alone module, the unit can be placed on a desktop or can be mounted to a wall.
