   3. Take the cables labeled as PWR and connect them to the power pad marked as PWR. Install four PH2 screws to secure the cables to the PIB, with a torque screwdriver set to the proper torque.
   4. Take the cables labeled as GND and connect them to the ground pad marked as GND. Install four PH2 screws to secure the cables to the PIB, with a torque screwdriver set to the proper torque.
   Note

   For reference, the torque required for the screws to be fully tightened/removed is 7+/- 1.0 lbf-in.
