The NET/SWI/001 is a store and forward Fast Ethernet 100Mbps switch designed for operating in harsh environments - capable of withstanding a temperature range of between -55°C and +105°C (-67°F - 221°F). The NET/SWI/001 supports IEEE-1588 Precision Time Protocol (PTP), delivers a high degree of synchronization, features eight full-duplex Fast Ethernet end nodes, Ethernet 802.3 and II 802.1Q tagged frames support. The absence of microprocessors and the implementation of hardwired routing means this switch is live on power-up.
