||
 The 4I71 is a stackable PC/104-plus card that combines a 100BaseT Ethernet MAC with a 9 port switch. The 4I71 makes it easy to connect multiple embedded system cards without the awkward power or mechanical problems with consumer type Ethernet switches. The 8 Ethernet ports support autonegotiation allowing connections with half and full duplex, 10 and 100 BaseT devices plus auto MDX, eliminating the need for crossover cables. The Ethernet MAC is a Micrel 8842P. The 8842P has advanced features such as hardware TCP checksum calculation for optimum MAC performance. And has drivers available for most operating systems. The switch has sufficient bandwidth to support full duplex wire speed connections on all ports. Price for the 4I71 is $147 in 100's. |
