iap 105 does not boot from scratch


I am a newbie to Aruba. I inherited two Aruba 105 access points which I tried to start up from scratch. The ap's are straight from the box. I want to use use the ap's without a controller.

I found the instant.aruba docs to start up the ap's. But both the ap's stop autoconfiguring after some DNS requests.

Here the startup sequence from one of the ap's:

Here it stops and nothing happens anymore.

I tried to connect without success using SSH and ftp.

Can someone give me a clue how to go on from here?

Re: iap 105 does not boot from scratch


There are two different AP105 units:


AP-105 (Only managed by controller)




IAP-105 (InstantAP units,can be used as virtual controller,and also converted and connected to controller)


to figure out which ap you bought,just turn over the ap - and look for a white sticker.

  • If it's written AP-105 .So it's can't be an instant unit. <if this is the case - u must use a controller.
  • If it's written IAP-105-so it's an instantAP unit and can act as a virtual controller. <if so u got a reset button in the back of the ap unit,reset it to factory default>


That's it .


Have a great week.





fromt the boot it's look like a AP-105 (not instant) unit.

You will need a physical controller for that to work. If it was an IAP, then it could operate as a virtual controller (VC), or join a cluster of one or more other IAPs that already has an IAP functioning as a VC.


I hope this helps,
