  • Torque driver (orange, 0.85 kgf cm)

  • Torx Plus 3IP half-moon bit

  • Torx Plus 4IP bit

  • Torx T6 70 mm bit

Removal

  1. Use the orange torque driver and Torx Plus 3IP half-moon bit to remove the two 3IP screws (923-09162) from Ethernet board connector cowling 1.

  2. Remove Ethernet board connector cowling 1 and save it for reassembly.

  3. Use the black stick to lift the end of the Ethernet board flex cable off the connector on the logic board.

  4. Stand the computer on its back with the front ports facing up.

  5. Use the adjustable torque driver and Torx Plus 4IP bit to remove the two 4IP screws (923-09167) from Ethernet board connector cowling 2.

  6. Remove Ethernet board connector cowling 2 and save it for reassembly.

  7. Use the black stick to lift the end of the Ethernet board flex cable off the connector on the Ethernet board.

  8. Use the adjustable torque driver and T6 70 mm bit to remove the two 6IP screws (923-08937) from the Ethernet board and power cord port.

  9. Lift the Ethernet board out of the housing.

Reassembly

  1. Position the Ethernet board in the housing.

  2. Use the adjustable torque driver and T6 70 mm bit to partially reinstall the two 6IP screws (923-08937) into the Ethernet board.

    • Note: The screws pass through screw holes in the Ethernet board and power cord port and thread into the housing.

  3. Press the end of the Ethernet board flex cable to the connector on the Ethernet board.

  4. Position Ethernet board connector cowling 2 over the connector.

  5. Use the adjustable torque driver and Torx Plus 4IP bit to partially reinstall the two 4IP screws (923-09167) into Ethernet board connector cowling 2.

    • Note: The screws pass through the cowling and Ethernet board and thread into the standoff screws of the back Thunderbolt 4 ports.

  6. Rotate the computer so the front ports are facing you.

  7. Press the end of the Ethernet board flex cable to the connector on the logic board.

  8. Position Ethernet board connector cowling 1 over the end of the flex cable. Then use the orange torque driver and Torx Plus 3IP bit to reinstall the two 3IP screws (923-09162) into the cowling.

  9. Position the computer so the rear ports face you.

  10. Plug an Ethernet cable into the Ethernet port to ensure Ethernet board alignment. Adjust the alignment of the Ethernet board until the end of the cable is easy to insert and remove.

  11. Set the torque value of the adjustable torque driver to 20.5 Ncm. Then use the adjustable torque driver and T6 70 mm bit to fully reinstall the two 6IP screws (1) into the Ethernet board.

  12. Set the torque value of the adjustable torque driver to 10 Ncm. Then use the adjustable torque driver and Torx Plus 4IP bit to fully reinstall the two 4IP screws (2) into Ethernet board connector cowling 2.
