AP70 loosing config - Setup as RAP

  • 1.  AP70 loosing config - Setup as RAP

    Posted Apr 13, 2012 09:17 AM

    We are using AP70s as RAPs on our inter-campus shuttle buses here at McGill University.  These APs get powered up and down many times per day and some of them have completely lost their config!

     

    Has anyone else seen this and if so is this an issue with AP70s or APs in general?

     

    The APs are powered by an Axis T8122 POE injector as it converts 12v DC from the bus to POE power for the AP as the AP only has a 5V input.

     

    I'm also wondering if an AP gets powered down during a boot cycle if this could maybe cause the issue?

    What version of code are you using?

    We just upgraded to 6.1.3.1 but when they lost their config they were running 5.0.4.5

    If it loses its config and it gets powered up and powered down all the time, that would seem to be memory corruption.  If you see it happening on the new version of code please open a case.  Being that the AP70 is end of life, it probably has not been seen or reported.

    Any tests I could run on the AP to check for memory problems?

    I'm going to speak in general here:

     

    I am not saying anything is wrong memory, per se.  To be technical, in ArubaOS 6.x, we write to the memory of the AP less, and that should reduce corruption due to the power being interrupted constantly while we are writing.  You certainly have a corner use case.

     

    If you see the same issues in 6.x, please open a ticket with TAC so we can work it.
