Installing a Software Load on a CMM Using a System Repair Drive


Use this procedure to install a software load on a CMM using a system repair drive. This is typically performed at initial system turn-up, during CMM replacement, or when network-based methods cannot be used.

Each CMM has a USB port from which it can boot. The USB port has the highest priority in the boot sequence. If a bootable device is attached to the USB port, then the CMM will try to boot from that device first.


This procedure erases all software, configuration, and commissioning data from the CMM.


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.


  1. Ensure the CMM on which you want to perform this installation is unseated from the chassis and that the chassis does not have an active CMM running.

    If the chassis has an active CMM, the active CMM might automatically install its software load onto this CMM at the end of this procedure.

  2. Plug in the system repair drive to the USB port of the CMM.
  3. Reseat the CMM.

    The CMM automatically boots to the installation utility on the system repair drive.

  4. Connect locally to the craft port of the reseated CMM.

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

  5. At the prompt, log in using the username admin and password admin.

    These credentials are hardcoded when booting from the system repair drive.

  6. To see the software version that is to be loaded, use the show_sw_version command.
  7. To see the software version that is currently loaded on the CMM, use the show_current_install command.
  8. Install the software.

    Use the command install_system to start the installation.

    You are prompted to verify if you want to proceed with the software installation. Choose yes to continue. For example:

    (bti7800-installer) install_system

    The installation process re-partitions and reformats the local drives and file systems, installs the base operating system, and installs the BTI7800 software. This step might take several minutes to complete.

  9. Remove the system repair drive when prompted and reboot the CMM.

    At the prompt type reboot.

    Here is a sample output. Actual output might differ.

    (bti7800-installer) reboot

    The CMM is now running with the software load from the system repair drive. It is ready for commissioning or restoration from a backup configuration. The CLI is not available until commissioning or restoration is performed.
