J2 is a 37 pin socket connector with four GigE ports brought out on it. Four twisted pairs are used for
each GigE port (8 pins total). This documentation refers to these pairs as a pair (GbEn_A_P / GbEn_A_N,
GbEn_B_P / GbEn_B_N, GbEn_C_P / GbEn_C_N, GbEn_D_P / GbEn_D_N) where n = a port number
from 5 to 8. J2 also has a serial console port on two pins (plus a signal ground return) and a zeroize port
on one pin (plus the same signal ground return).
