The modularity built into the PowerVault 51F switch allows: Support of 8-unit (U) universal ports. Each card to accommodate two 1-gigabit per second (Gbps) ports (2 Gbps total per card). Each port is full-duplex (bidirectional at this rated throughput). GBIC interface support of different transmission media for each port. The PowerVault 51F switch has the following features, ensuring reliability: POST Error monitoring Temperature and fan-speed monitoring Low component count Optional redundant power supply Redundant fans The PowerVault 51F switch has the following features, enhancing serviceability: Simple enclosure Loopback test modes for service Hot-pluggable fans and power supply No jumpers or switch settings Components are enclosed in an air-cooled chassis that may be either mounted in a standard rack or used as a stand-alone unit. The chassis includes a serial port and an RJ45 Ethernet connection for switch setup and management. The switching function is based on a central memory bank associated with its data path control. Each switch port stores received frames in this memory, passing a buffer pointer to the forwarding port's transmitter. The switch uses cut-through routing to route frames from the receiving port to the transmitting port, providing the transmit port is free, without waiting for the end of the frame to be received.
