======UPGRADE VIA RS232======


The first thing that should be made is to have the file of upgrade of the SuperStack. For the upgrade to the version 2.64, it's necessary to have the following files where XX and YY corresponds to the version number, for this case 2_64:  


  Update.exe  
  Ldr_b02.bin  
  Ldr_b02.err  
  S2sXX_YY.bin (For this case: s2_s02_64.bin)

Get into the directory where the files mentioned in the first item of this procedure are located. Execute the following command:  


  Update s2s02_XX.bin [enter]

Once you have pressed [enter], wait until the communication speed changes to 19200 and then plug the Switch to the power source.  
  
  
  
Wait until the whole process has finished and never stop this process, this could cause bigger damages in the Switch.  
  
Once the upgrade has finished, enter the main menu of the switch with the user admin and the password "**Enter**"   


Once located in the main menu confirm the new version of the switch entering the command sys dis [enter], like below:
