Install the Embedded Network Module and WLAN module

See this topic to learn how to install the Embedded Network Module.

About this task


  1. Make sure both Riser 1 and the M.2 boot adapter are removed. If not, remove them (see Remove the PCIe riser assemblies and adaptersRemove the M.2 boot adapter and drives).
  2. If necessary, install the WLAN module and WLAN antenna cables. If not, go to step 3.
    1. Place a washer between the hex nut and the antenna cable. Then, tighten the hex nut with the wrench that comes in the air baffle as shown to secure the antenna cable. Repeat the same procedure on the other antenna cable.

      • Make sure to slide the rubber sleeves to next to the connector.
      • Make sure the cables are connected to the right connector.
        • The blue cable should be connected to connector 2.
        • The black cable should be connected to connector 1.
      • To make sure the cables are connected properly, try rotating the cables slightly horizontally. They should stay attached to the WLAN module.
    3. Align the cable holder with the WLAN module, and slide the holder over the module until it clicks in place.

    6. Align the WLAN module with the connector on the Embedded Network Module. Then, rotate the module down, and secure the WLAN module to the Embedded Network Module with a screw.
      Make sure to secure the cables in the cable clips, and route the blue cable over the black cable.
