Hi all, I was just pulling out a list of different things to graph via SNMP and I came across this strangeness on two J6350's (JUNOS 10.2R3.10). When I have been pulling the data out to graph, the fan speed seems to jump between 37,678 RPM and 9,820 RPM. This is consistant on both routers, and the speed seems to jump about at random. As an example:
root@acc-bdr2> show chassis fan Item Status RPM Measurement Jseries CPU fan OK 9820 Spinning at high speed Jseries Chassis fan 0 OK 37678 Spinning at high speed Jseries Chassis fan 1 OK 37678 Spinning at high speed root@acc-bdr2> show chassis fan Item Status RPM Measurement Jseries CPU fan OK 9820 Spinning at high speed Jseries Chassis fan 0 OK 9820 Spinning at high speed Jseries Chassis fan 1 OK 37678 Spinning at high speed root@acc-bdr2> show chassis fan Item Status RPM Measurement Jseries CPU fan OK 37678 Spinning at high speed Jseries Chassis fan 0 OK 37678 Spinning at high speed Jseries Chassis fan 1 OK 9820 Spinning at high speed Each of those was approximatley 1 second apart. >From looking at the thresholds the way I am reading it is the fans should be on the "normal" speed: root@acc-bdr2> show chassis temperature-thresholds Fan speed Yellow alarm Red alarm Item Normal High Normal Bad fan Normal Bad fan Chassis default 48 54 65 55 75 65 Routing Engine 55 60 80 80 90 90 root@acc-bdr2> show chassis environment Class Item Status Measurement Temp Routing Engine OK 27 degrees C / 80 degrees F Routing Engine CPU OK 49 degrees C / 120 degrees F Fans Jseries CPU fan OK Spinning at high speed Jseries Chassis fan 0 OK Spinning at high speed Jseries Chassis fan 1 OK Spinning at high speed Power Power Supply 0 OK Power Supply 1 Absent Both routers report the exact same fan speeds (9,820 and 37,678) which I find is odd, I though it would have been unlikely that they are both the same... Has anyone come across this before? Is this expected behaviour? The closest thing I have found is KB12718 - "Why am I seeing fan in high speed mode on J-Series?" - but I belive the actual fan speed is being reported incorrectly in this case.
