Environment
  • Securestack
  • A2-series
  • B2-series
  • C2-series
  • B3-series
  • C3-series
  • A4-series
  • B5-series
  • C5-series
Procedure
      1.  From the management switch, copy the firmware to other stack units using this command :
Switch(su)->set switch copy-fw destination-system <Unit-NUMBER>
     2.  Upgraded Unit requires a reboot in order to run the newly copied image and allowing it to join the stack. 
Switch(su)->reset <Unit_NUMBER>


Note: C5 or B5 Firmware version 06.42.xx and lower cannot talk to switches on 06.51.xx / 06.61.xx or higher due to 06.42.xx code track has different programming for stack port intercommunication.  Any C5 or B5 on 06.42.xx should be manually upgraded prior to joining to a stack as the above commands will not work 

Additional notes
Before issuing the reset command wait for the CLI prompt to come back on the console.  Do not power off the upgraded unit prior to the cli prompt coming back on the stack manager.
