How to Install a CMOD Filler


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.

  1. Prepare the server for service. See How to Prepare for Service.
  2. If necessary, remove the CMOD. See How to Remove a CPU Module (CMOD).
  3. To unlock the CMOD filler lever, squeeze the green-colored tabs on the end of the lever.
  4. Rotate the lever to the right to its fully open position.

    The lever does not extend beyond 90 degrees.

  5. Position the filler in the slot with the lever to the right.
  6. Slide the filler into the slot until it stops.

    Do not push the filler beyond this point.

  7. Ensure that the pawl on the lever is aligned with the slot in the CMOD sidewall.
  8. To install the filler, rotate the lever to the left and firmly push it until it is flush with the front of the filler.


    Caution - Pinch point. Keep hands and fingers clear of the back side of the lever.

    Rotating the lever to the left causes the pawl to engage the sidewall . Push the filler into the slot until it is seated.

  9. To lock the lever, push the lever until you hear the locking latch click.
