J1 is a 37 pin socket connector with four GigE ports brought out on it, as well as power and a zeroize
port. 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 1 to 4. J1 has a serial console port on two pins (plus a signal
ground return). J1 has a zeroize port on one pin (plus the same signal ground return).
