Remove a CMOD

You need to remove the CMOD to service it or its internal components.

Before You Begin

For component serviceability, locations, and designations, see About System Components.

  1. Prepare the server for warm or cold service.
  2. Identify which group of fan modules (left or right) to remove to access the CMOD.

    In an eight-CMOD configured server, CMODs belong to either a left or a right group. CMODs 0-3 are in the leftmost group, and CMOD s 4-7 are in the rightmost group. If you know the group, then you know which group of four fan modules to remove. If you are removing a CMOD in a failed state, the lit fault indicator for the CMOD on the FIM shows you the group to which the CMOD belongs. In a four-CMOD configured server, remove the leftmost group of fans.

  3. Remove the fan modules. See Remove a Fan Module.
  4. Remove the fan frame. See Remove a Fan Frame.
  5. Identify the CMOD.
  6. To unlock the CMOD, squeeze together the green tabs on the end of the CMOD lever.

  7. To disconnect the CMOD from the connector on the midplane, rotate the CMOD lever downward and away from the CMOD.


    Caution  -  Pinch point. Keep your fingers clear of the underside of the lever.

    The lever disconnects the CMOD from the midplane and its DPCC.

  8. Use the lever to slide the CMOD partially out of the server until you can grab it with both hands.
