How to Remove a CPU Module (CMOD)

An animation of the procedure to remove a CMOD is available. See animation showing CMOD removal.


Caution - Airflow and temperature-related issues. For proper airflow and cooling, all CMOD slots must contain either a CMOD or a filler module. Do not operate the server with unoccupied CMOD slots.


Caution - The CMOD is not a hot-plug component.

Before You Begin

  1. Prepare for service. See How to Prepare for Service.
  2. To unlock the CMOD, squeeze together the green tabs between the lever handles.

    This action produces a click sound and releases the handles.

  3. To disengage the CMOD, simultaneously rotate both levers outward away from the center of the module. Do not attempt to remove the CMOD now.

    Rotating the levers outward causes the pawls on the end of the levers to engage the sidewall of the chassis and pull the CMOD out of its internal connector.

  4. Use the handles to pull the CMOD partially out of its slot.

    Pull the CMOD out so that approximately 6 inches extends from the front of the chassis.

  5. Rotate the levers inward until they are closed and locked.


    Caution - Potential physical harm or component damage. Because of the length and weight of the CMOD, one or more people should assist in the removal of the CMOD at this point.

  6. To remove the CMOD, have an assistant support the CMOD as you slowly pull it out the slot.


    Caution - Potential overheat condition. Unoccupied module slots disrupt air flow and temperature control within the server. Replace the module with a filler module or another CMOD.
