  • 1.  Mx204 showing one psu absent when both psu are working fine

    Posted 03-04-2022 10:31

    Hello,

    We are getting strange output of command when we execute wo commands for chassis hardware.

    Model: mx204
    Junos: 20.3R1.8
    When we run #run show chassis hardware
    PEM 1 REV xxxxxxxxxxxxxxxxxx    JPSU-650W-AC-AO


    run show chassis environment
    Power PEM 0 Absent
    PEM 1 OK 31 degrees C / 87 degrees F

    But both PSU are plugged in and showing green active light.
    Any idea why Mx204 not showing both psu active?

    Thanks

    Are you sure it's installed in the chassis fully? Does it work while plugged into slot PEM1?

    Do you have any alarms that might give more information?

    show chassis alarms
    show system alarms

    we had the same problem in the past.
    We had fixed it with upgrade to Junos: 20.4R3.8.
