IAP-105 in a rebooting loop

  • 1.  IAP-105 in a rebooting loop

    Posted Oct 12, 2012 10:32 PM

    Hi all,


    I just received two IAP-105 access points for evaluation from one of the resellers, and I configured one fine, and connected the second one to the same LAN expecting to join the first one.


    I noticed that it seems to constantly reboot, which was confirmed when I logged on via teh console.


    Could anyone tell me what's the problem here, as I'm new to Aruba but I'm very impressed with how easy it was to configure the first one.


    thanks a million,

    It is running ADP to look for controller. Did you try to use factory_reset command? If it is not working, reboot the AP and break the boot  process. Start TFTP and proceed the following command to put instant image:


    #upgrade os <tftp_server_ip>:<Instant_image_name>


    For example: #upgrade os ArubaInstant_Orion_6.1.3.1-


    And reboot the AP after the process, it should be start with the instant image.

    I agree with Somnium.  You can see in the bootup process that it is booting AOS b28288 which is a controller-based image.


    Either this IAP has been configured to be managed by a controller  * or *   this is not an IAP (controller only model).


    Flip the suspect unit over and take a look at tthe labels of the back  Look for one small label that states "IAP-105-US" (if in the US).   If you do not find "IAP-105-US" but, rather, find "AP-105" then this is a controller-based AP and connot become an IAP and cannot be managed by your other IAP.


    If it is an IAP-105-US then use the reset proceedure to revert back to an IAP:


    1. Unplug the IAP

    2. Get a paperclip and insert the paperclip into the small hole on the back of the IAP (top-center) and hold down the reset button.

    3. While holding down the reset button plug the IAP back in and continue holding the reset button for 10 seconds.

    4. Release.

    Hi all and thanks for the prompt responses :)


    I chcecked on the back and both have the same label, IAP-105


    I did the reset button procedure, and still the same, and I also did the factory_reset from the CLI, and also copied the latest image from Aruba via TFTP, which seemed to be copied OK as it said it copied OK and erased the flash to write the new image, but when I rebooted it again, the sequence is exacttly the same as before, it's like booting the old image somehow...


    Does the device have two flash locations, and you could choose which image to boot?


    Thanks  mill for your help,

    OK, I got it working!!


    I compared the boot process of the non-working AP with the working one, and I noticed that while the working one was booting the new OS :


    Aruba Networks
    ArubaOS Version (build 35320 / label #35320)
    Built by p4build@cyprus on 2012-09-15 at 13:43:44 PDT (gcc version 4.3.3)


    - the non-working AP was still booting an older version, although I have upgraded it via TFTP:


    Aruba Networks
    ArubaOS Version (build 28288 / label #28288)
    Built by p4build@stan on 2011-05-11 at 11:55:37 PDT (gcc version 4.3.3)


    I have searched on the Support website and found that it has 2 partitions (partition 0 and partition 1).


    I compared the environment variables in the boot menu and were the same, both APs were booting from the same partition (partition 1):


    apboot> printenv
    bootcmd=boot ap


    So knowing that I succesfuly upgraded the OS but it wasn't on partition 1, I concluded that the Instant AP OS is onpartition 0, so I changed the environment variable:


    apboot>setenv os_partition 0


    Once rebooted, it started OK and joined the other AP immediately :)


    Thanks again for all who have responded.

    Just another question on the same topic:


    How true is the following post then, which says that, when the AP has been used in a Controller-based mode (using partition 0) and you reset it to the default, it boots from partition 1 where the Instant OS is saved?


    It didn't really match with what I found working in may case...
