    I am getting this error on a brand new JL658A

    Diagnostic tmp1 failed with error code 0x2000000 on management module 1/1

    The fan is at max. 

    Also, when I run show environment temperature:

    Hello Ivan, in my opinion (and only looking at logs you posted) that VSF Member 1 "1/1-Inlet-Air management-module 0.00 C fault" log line sounds related to an Hardware issue (did that inlet air temperature sensor failed?) especially because the VSF Member 2 reads "2/1-Inlet-Air management-module 27.12 C normal" which sound more reasonable. Less probably, a software related issue: with that regard, what software version is exactly running on your ArubaOS-CX VSF?

    Hi Ivan,

    This is definitely a HW related issue and the device needs to be replaced. Either contact your seller, or open a case with Aruba.

    I had this issue with one of my new 6300Fs, there was a faulty fan and it caused them all to run at full speed. The 6300 Release notes state the following:


    Switch fans will run at full speed when a fault is detected with the temperature sensors in the switch. This is
    normal behavior to ensure overheating does not occur. Should the fans run at full speed at unexpected times,
    check the output of show environment temperature and show environment fans, then contact support for
    further assistance.​


    You need to initiate an RMA with your seller or with Aruba directly. For me they send a new switch out and it arrived in two days, then you send the faulty one back with the shipping label they provide.

    Thanks for the replies,

    After talking with Aruba support we deducted that it was a faulty sensor, so we are going to get an RMA.

    Device has already been swap with another one and problem disappear.

    Thanks once more.
