Upgrading Older SmartServer Hardware to Newer Software

To upgrade older SmartServer hardware to newer software, follow the guidelines below.

  • Update (using GLPO file), or re-image, to upgrade the SmartServer to a new software version.

    • Starting with

  • With SmartServer 3.

    • 30.057

  • 3 and higher, you need a device capacity license, unless you are

    • using the

  • using the SmartServer for RNI or IP-852 routing only. 

    • Starting with

  • With SmartServer 3.

    • 30.057

  • 3 and higher, if you want

    • allow

  • the SmartServer to be upgradable to a newer software version, then you will also need

    • to have maintenance license.
  • Device capacity and maintenance licenses are not affected by a software upgrade or re-image. That is, once licensed, the license remains on the SmartServer after a software update or re-image.

Downgrading Newer SmartServer Hardware to Older Software

To downgrade newer SmartServer hardware to older software, follow the guidelines below.

  • Downgrade only to supported software. Software versions are hardware specific.
  • Newer SmartServer hardware cannot always use older software.
    • If you downgrade to a software version that does not support the specific hardware, then this process can cause the SmartServer to be inoperable and invalidate the warranty. 
    • If you do mistakenly downgrade the SmartServer to an unsupported version, then re-image the SmartServer from the U-Boot prompt to a supported software version in an effort to recover the SmartServer.
    • Downgrade a SmartServer using re-image. The CMS Devices widget (GLPO update) cannot be used to downgrade a SmartServer

  • a maintenance license.

  • Device capacity and maintenance licenses are not affected by a software upgrade or re-image. That is, once licensed, the license remains on the SmartServer after a software update or re-image.

Depending on the availability of parts, hardware parts can change between different hardware revisions. These parts include the CPU, PMIC, or memory. The SmartServer serial number includes the hardware revision, but the hardware revision by itself does not always indicate what is inside the SmartServer. Determining how many CPU cores are used, and the PMIC version, is necessary for this information.

Backing up and Restoring the SmartServer

For backups backup and restore operations, follow the guidelines below.

  • Full backups can only be restored to the SmartServer hardware that supports that software version. Software versions are hardware specific.

  • To support a newer hardware version, back up the database and settings so that you can restore only the database and settings using the Import/Export (

    • Image Removed

  • image-20250213-162225.pngImage Added) button.

    • On older software versions, the settings can be exported with the Settings button (

    • Image Removed

    • image-20250213-162240.pngImage Added) → Export action.

  • For example, since SmartServer 3.26 is not supported on the Rev F quad core, you cannot restore a backed up full image for SmartServer 3.26 on the Rev F hardware.

    • On the

    • With SmartServer 3.26, you can back up the database, and separately back up the settings using the

    • Setting button → Export action

    • Settings button (image-20250213-162255.pngImage Added) → Export action. On the new SmartServer, import the database and then the settings.

Checking Your SmartServer Hardware

To check your hardware, follow the guidelines below.

  1. Determine the hardware version and whether you are using a dual core or quad core SmartServer

...

  1. ; look at the serial number that is printed on the label located on the bottom of the SmartServer.

    1. In most cases, the serial number that is shown on the SmartServer System Configuration page is the same serial number as the one that is printed on the SmartServer label.

...

    1.  

    2. A board revision number is incorporated into the serial number. Revision information appears as an alpha character a-z in the format 44yywwrxxxxx, where ww is the week of the year, yy is the year, and r is hardware revision. xxxxx indicates other characters in the serial number.
      Example: 442050F00100 

      1. Datecode: 2050F

        1. 50th week of 2020

        2. Hardware revision F indicates a quad core. All SmartServers delivered from the factory since 2021 are quad core.

    3. You can also determine whether the SmartServer is a dual or quad core by using the SSH/console command lscpu.

      1. 2 indicates dual core

      2. 4 indicates quad core

  1. Verify the PMIC type using the command shown below.

    Code Block
    sudo /root/.setup/pmic/pmic_checker.sh

    • PFUZE100 – supported for all SmartServer releases.

    • DA9063 – supported for SmartServer 3.3 and higher.

Example

The SmartServer has the serial number 442205H00100, and lscpu shows four CPUs (or datecode 2022) and a DA9063 PMIC. 

  • For serial number

    442205H00100

    442205H00100: 2205H indicates manufacturing in the 5th week of 2022; H represents revision H.

  • This SmartServer is a quad core with a DA9063 PMIC.

  • This SmartServer can only use software version 3.27.001, or 3.30.057 and higher (3.30.001 through 3.30.056 is not supported).
