Remove the PMB side SMA assembly or SMA filler​

Procedure
  1. Make preparation for this task.
    1. If applicable, remove the WLAN antennas. See Remove the WLAN antennas.
    2. If applicable, turn the screw between the two SMA connectors clockwise to shorten the connectors into the chassis.
      Note
      Make sure that the SMA connectors are shortened into the chassis; if the SMA connectors are extended and out of the chassis, the SMA assembly can not be removed successfully.

    5. Press the side of the cable holder; then, insert the cable holder to the slot on the wireless adapter.
      Figure 9. Inserting the cable holder

  5. Gently remove the cables from the cable guide and the cable clip on the chassis.
    Note
    If necessary, disconnect the following cables from the system board for easier operation.

    • Fan cables

    • Fan direction switch cable

    • Intrusion switch cable

  6. Remove the SMA assembly from the node.
    1. Loosen the screw that secures the SMA assembly.
    2. Lift the SMA assembly to remove it.
