Uncommissioning a CMM

 

Use this procedure to uncommission a CMM. It is recommended that you uncommission a CMM before removing it from a chassis and placing it into storage (for example, as a spare). Uncommissioning resets the configuration database to the factory default configuration and removes all commissioning settings. It ensures that the CMM behaves predictably when you later insert it into a chassis.

Warning

Service modules are automatically warm reloaded as part of this procedure. Software-based features on the service module (such as PM collection, APSD, APR, FPSD) are disabled while a service module warm reloads.

Note

This procedure removes all existing provisioning and commissioning settings.

  1. Uncommissioning is performed on one CMM at a time.

    In a dual CMM chassis, seat the CMM you want to uncommission and unseat the other CMM. If you want to uncommission both CMMs, work on the active CMM first and unseat the standby CMM.

    In a single CMM chassis, seat the CMM you want to uncommission.

    In a satellite chassis in a multichassis system, leave both MRMs seated.

  2. Log in to the CMM locally over the craft serial or craft Ethernet port.

    For information on how to do this, see Logging In to the CMM Craft Ethernet or Craft Serial Ports.

  3. Enter setup mode.
  4. Reset the database to the factory-default configuration and remove all commissioning settings.

    For example:

    (cmm-setup)$ factorydefaults

    After a short time, the following message is shown:

  5. Reboot the CMM.
    (cmm-setup)$ reboot

The CMM reboots into a uncommissioned state with the factory-default configuration. When the CMM finishes rebooting, you will see the login prompt. This might take several minutes.

In a dual CMM chassis, if you want to uncommission the second CMM, unseat the newly uncommissioned CMM, reseat the second CMM, and repeat this procedure.

The CMM is now ready for commissioning.
