Page 9: Operation
OPERATION SWITCH The 4I71 is basically a dual port Ethernet interface and a 8 port switch on a single card. The Ethernet MAC connects to a built in 2 port switch on one of the 8 switch ports, leaving 7 switch ports and one of the original 2 ports of the Ethernet chip available. Since the Ethernet MAC has a local Ethernet interface to its switch port, system software will only see a standard Ethernet interface, so normal KSZ8842 drivers can be used. -
