  • 1.  EX2300 cluster red alarm

    Posted 12-18-2019 05:14

    Hello,

     

    I have virtual chassis with 2 EX2300 switches. Today, I saw red led on one of the switches, but I couldn't find the reason of that.

     

    How can I find the issue?

    the next alarm you may want get rid off is the yellow one associated to not having set a rescue configuration. Once you have a working configuration you want to fall back on, just issue a   set system configuration rescue save to at least get rid of the alarm.
