4I71 1
GENERAL
DESCRIPTION
The 4I71 is a stackable PC/104-plus card that combines a dual port 100BaseT
Ethernet MAC with a 8 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-MDIX, eliminating the need for crossover
cables.
The Ethernet MAC is a Micrel KS8842P which has drivers available for most
operating systems. The switch has sufficient bandwidth to support full duplex wire speed
connections on all ports.
