    Hi guys,

    I'm a newbie here with Juniper switches please don't get too hard on me. 😉

     

    Ok, so we just took over a property with a bunch EX2200 for their Access Point. 

    I'm trying to upgrade the JUNOS because I think it's pretty old. 

    The current version is 12.1R5.5 and I'm seeing I can have it upgraded to 12.3 or 14 or even 15 version. 

    So I did try it slowly by using the 12.3 version first by using the Web GUI. 

    I did the Maintenance -> Software -> Upload Package -> Upload and Install Package. 

    I uploaded and install the 12.3R12 version of firmware but for some reason I don't think it's updating because after rebooting the switch manually, I'm still seeing the current 12.1 version Junos. 

    Am I missing something here, guys?

     

    I know this is probably pretty easy problem to fix. 

    Any help would be appreciated.

     

    Thank you!!

    Note that 12.3 is the highest Junos recommended for the ex2200 due to memory limitations.  The version you are trying is the highest recommended 12.3r12

    Since the update is failing with jweb you need to see why.  Check to see if there are any logs.

    show log messages

     

    If not, try doing the upgrade on the cli so you get the feedback and try the validate option first on the cli

    request system software validate FILENAME
