TCX1000 Series Software Upgrades


This topic provides an overview of how software upgrades work on the TCX1000 Series of devices and it includes the following subjects:

Software Upgrade Overview

TCX1000 Series devices support nondisruptive software upgrades where the device retains the last known configuration and passes traffic uninterrupted. You can perform software upgrades on a single device or on multiple devices simultaneously. All software upgrades are initiated from the proNX Optical Director.

Software upgrades are delivered as a single file, which contains all the software for the various components of the device. The TCX1000-RDM20 uses a two bank boot structure which allows for the running load to remain in place while the new load is installed to, and run from, the other bank. This enables reversion to the original running load should an upgrade fail or you choose to revert before the process completes. Banks are referred to as A and B and either can function as the currently active bank.

There are two phases in the software upgrade process: Stage and Activate. After you select the proNX Optical Director SFTP server and filename in the management system, you can chose to either Stage or Activate the upgrade.

  • Staging copies the software upgrade file to the TCX1000 Series device.

  • Activate performs the upgrade on the device

After you initiate the software upgrade, the management system notifies you when the upgrade is complete.

Overview of Performing Software Upgrades on the TCX1000-RDM20

To upgrade the software on a TCX1000 device:

  1. Download the TCX1000 software from the Juniper Networks website.

  2. Save the TCX1000 software upgrade file to one of the proNX Optical Director SFTP servers.


    The path of the software upgrade file must be relative to the directory you provided when the SFTP server was configured, or if no path was selected, then it must be relative to your SFTP home directory. You can also browse the SFTP server for the software upgrade file.

  3. In proNX Optical Director:

    1. Select the SFTP server on which the software upgrade file resides.

    2. Select the name of the TCX1000 software upgrade file.

    3. Select the Stage operation to copy the software upgrade file to the TCX1000 device. Ensure this tasks completes successfully before proceeding.

    4. Select the Activate operation to upgrade the device software. Ensure this tasks completes successfully before proceeding.
