This section describes how to determine if a SmartServer software version can be used for your specific SmartServer hardware. Read this section before upgrading or downgrading a SmartServer, or doing a backup and restore.

  • Do not downgrade the SmartServer to an older software version until you make sure the old software version supports the newer SmartServer hardware. Failure to do so may make the SmartServer inoperable and invalidate the warranty.
  • Do not upgrade a dual core SmartServer above to any release after SmartServer 3.12.
  • Do not restore a full backup on a SmartServer if the original software version is not supported on the new hardware. In this case, backup only the database and settings, and restore only the database and settings.

  • 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 () button.
    • On older software versions, the settings can be exported with the Settings button () → 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 SmartServer 3.26, you can back up the database, and separately back up the settings using the Setting button → Export action. On the new SmartServer, import the database and then the settings.

Checking Your SmartServer Hardware


  1. Determine the hardware version and whether you are using a dual core or quad core SmartServer by looking 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. Verify the serial number by checking the label.
    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

        Code Block

        Dual core SmartServers can use SmartServer release 2.4 to 3.1. Quad core SmartServers software versions are dependent on which PMIC you are using. 

  2. Check which PMIC is used. There are at least two types of PMICs: DA9063 and PFUZE100. Only DA9063 is supported on a SmartServer 3.27.001, or 3.30.057 and higher (3.30.001 through 3.30.056 is not supported).

  • For serial number 442205H001002205H 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).
