The SX8205R unmanaged Ethernet switch provides five 10Base-T/ 100Base-TX ports for the transport of bidirectional Ethernet data. Operating as a single switch in a network, the SX8205R connects to a maximum of five 10Base-T/100Base-TX Ethernet devices. If a larger switched network is needed, multiple SX8205R switches can be connected by allowing a port on each switch to be used as an uplink port. Cable connections from the SX8205R switch to a compatible device or to another SX8205R switch are supported up to a maximum of 328 feet (100 meters). 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 port to automatically negotiate between 10 Mbps and 100 Mbps data rates and between full-duplex and half-duplex modes. If autonegotiation is not desired, a port can be forced to specific modes of operation: 10 Mbps or 100 Mbps data rate, half-duplex 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 SX8205R 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.
