3 ernet Ports .4.4 PT5MC Eth
Each of the two PT5MC sites on the HW400c/2 have two 10/100/1000 Mbps ports
connected to the Ethernet switch. The signals conform to PICMG ECN 2.15-1.0-
001, using the first 24 pins of the respective JN4 connectors.

FET switch specially designed for signals such as Gigabit Ethernet. The PTID bits

N4 pins 5, 6, 11, 12, 17, 18, 23 and 24 are switched to ground through discrete FETs
