    Upgrading System Software for a Network Element

    Use this procedure to upgrade the system software for a network element.

    The (S)FTP server must be selected, set up, and active prior to downloading system software to an NE. See Adding an FTP or SFTP Server for information about setting up an (S)FTP server.

    PSM supports network element software upgrade for the following:

    • BTI7800 Series network elements
    • BTI7000 Series network elements
    • BTI800 Series network elements (FTP only)
    • BTI700 Series network elements (FTP only)

    Note: A software upgrade to a previous software version is not supported.

    Note: To protect network and server resources, limits are placed on the number of upgrades that can be run concurrently. See Managing Task Status for more details.

    1. Right-click a network element in the Network tree view, and then click Software Upgrade.

      The Software Upgrade dialog is displayed.

      Alternatively, select multiple NEs, right-click and choose Software Upgrade. In this case the following dialog is displayed. If a combination of mixed NE types are selected then the Select Device pulldown contains the various NE types available for upgrade, and you must select a single NE type to upgrade.

      Note: Exercise caution when upgrading multiple NEs concurrently. This feature has been provided for convenience and should only be used after you have performed a limited rollout of the new software and resolved any deployment issues.

    2. In the Software Upgrade dialog, select an active FTP server from the pulldown menu.
    3. Click Browse to navigate to and select the software version that you want to download. For BTI7000 Series software, select the directory of the release. For BTI700 Series and BTI800 Series software, select the compressed file with the correct device type and extension.

      Note: You can only browse within the starting directory and its subdirectories. The starting directory is the directory you specified when adding the (S)FTP server.

      The version you selected appears in the Software field of the Software Upgrade dialog.

    4. For BTI7000 Series devices, select one or more check boxes as desired. Only valid combinations are allowed to be selected. The general sequence is to check, load, invoke, and then commit the upgrade. You can choose to perform all of this in one step or in multiple steps at different times.
      • Check - This selection verifies that the system is ready for the upgrade process, and that the load files on the server are accessible.
      • Load - This selection downloads the software images from the server to the SCP.
      • Invoke - This selection installs the new load on all circuit packs in the system and reboots each card in the system.

        Note: If you are using inband management communications for PSM through a BTI7000 Series NE, then you will not receive a response from the NE indicating success when performing the Invoke phase of a software upgrade. In this case the upgrade process can be completed by using the proNX 900.

      • Commit - This selection completes the upgrade procedure, and can only be performed after an Invoke has taken place, either in a previous step, or with Invoke concurrently selected with Commit.
      • Cancel - This selection cancels the upgrade procedure and rolls the system back to the previous set of loads. It can only be selected after an Invoke has taken place previously and prior to a Commit.

      For BTI700 Series and BTI800 Series devices, select the desired check boxes:

      • Load - This selection downloads the software image from the server.
      • Commit - This selection activates the new image.

      PSM attempts to validate the BTI700 Series file using the selected filename. If the filename does not indicate a BTI700 Series-specific device, a warning is displayed.

    5. Click OK.

      Use the Tasks tab in the main window to monitor the progress of the software upgrade.

      Note: PSM-generated NE software upgrade related alarms are not automatically cleared once the problem has been resolved. Any PSM-generated NE software upgrade alarms that occur must be manually cleared. To manually clear a PSM-generated alarm, right-click on the alarm and choose Clear NMS Generated Alarm. Once cleared, you cannot restore an alarm.
