To remove all electrical current from the device, ensure that all power cords are disconnected from the power source.

About this task

Attention

• Read Installation Guidelines and Safety inspection checklist to ensure that you work safely.

• Touch the static-protective package that contains the component to any unpainted metal surface on the server; then, remove it from the package and place it on a static-protective surface.

Procedure

1. Depending on the model, install the SMA assemblies or SMA fillers.
   1. For models without wireless module, install the SMA fillers.
      1. Align the notches of the SMA filler with the guide pins on the chassis; then, carefully lower the SMA filler until it is firmly seated.
      2. Secure the SMA filler with one screw.

      Figure 1. Installing the SMA filler
      
      
   1. For models with wireless module, complete the following steps to install SMA assemblies..
      Note

      This task requires a wrench. If necessary, use the wrench that comes in the PMB air baffle. Loosen the screw that secures the wrench to disengage the wrench from the air baffle.

      Figure 2. Disengaging the wrench
      
      
2. Locate the SMA assembly to be installed:
   Figure 3. SMA assembly locations
   
   

   1 Processor side SMA assembly (SMA connector 1, 2)

   2 PMB side SMA assembly (SMA connector 3, 4)

3. If the bracket is secured to the SMA assembly, loosen the screw that secure the bracket; then, separate the bracket from the SMA assembly.
   Figure 4. Removing the bracket
   
   
4. Fasten the cables to the bracket with the wrench.
   • For the processor side SMA assembly: Fasten the gray cable (XCC WLAN #1) and the white cable (XCC WLAN #2).
   • For PMB side SMA assembly: Fasten the blue cable (x86 WLAN #3) and the black cable (x86 WLAN #4).

   Figure 5. Fastening the cables to the bracket
   
   
5. Insert the bracket into the SMA assembly until it is firmly seated; then, secure the bracket with one screw.
   Important

   • Fully fasten the screw until the SMA connectors are inside the SMA assembly. If the SMA connectors are out of the SMA assembly, the SMA assembly can not be installed successfully.
   • Make sure the order of the cables is as shown in the following illustrations.
     • For the processor side SMA assembly:
       
       
       

       1 The gray cable (XCC WLAN #1)

       2 The white cable (XCC WLAN #2)

     • For the PMB side SMA assembly:
       
       
       

       3 The blue cable (x86 WLAN #3)

       4 The black cable (x86 WLAN #4)

6. Install the SMA assembly.
   1. Align the notches of the SMA assembly with the guide pins on the chassis; then, carefully lower the SMA assembly until it is firmly seated.
   2. Secure the SMA assembly with one screw.

7. Route the cables.
   1. For the cables of PMB side SMA assembly, secure the cables into the cable clip on the chassis; then, route the cables into the cable guide on the side of 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

   2. For the cables of processor side SMA assembly, route the cables into the cable guide on the side of the chassis.
   3. Secure the cables into the cable clip near to the wireless adapter.
