    My EX-3200 is generating about

     

    "FPC 0 PEM 0" failure message ...

     

    What does it indicate, as all my services are running fine on that switch ...

     

    What is PEM (Power Entry Module) and what's its effect on the working of the Switches

     

    Rasmus

    Thanks

    There could be any number of problems with the power supply.  It sounds like the problem isn't causing any service interruption yet, but I would put a call into JTAC and futher troubleshoot the issue and RMA the power supply if necessary.

    I just had a problem with an EX4200-48PX stack of two switches.  They too were reporting PEMs not supported and my Cisco 1240 wireless access point didn't run off of POE.  It seems that the newer PX series of  EX switches must have the new PWR2 power supplies.  Once I inserted the PWR2 PSs everything worked.
