    By the way I cannot open this case to JTAC because support of this box is over

    Any idea please?

     

    Thank you before,

    Try connect to console again by using putty app. Don't use SecureCRT. Good luck! 🙂

    Try using spacebar, not Control-C.

    If the instructions in kb27255 don't work, do contact Juniper support.  Most of the EX line has a limited lifetime hardware warranty.  Juniper is standing behind these products in many of these types of cases.
