Wireless Access

I have a setup of four AP 105's.  Three of them work just fine, but the fourth boots with "invalid image format" errors and keeps cycling through reboots.  I have tried many of the suggestions provided by the community to others that have experienced this problem (purgeenv, factory_reset, clear os) with no success.  The last thing I tried (setenv serverip) at least changed the behavior of the boot process in that it appears to at least try to download the OS image from the controller, but the result is the same - endless reboots. Here is the last log from a boot attempt:

I have noted a difference between the three AP's that work and the one that doesn't.  The three that work begin their boot with:

 

APBoot 1.4.0.3 (build 37726)
Built: 2013-03-21 at 20:13:41

 

while the one that does not work begins:

 

APBoot 1.2.4.4 (build 26618)
Built: 2011-01-07 at 13:42:04

 

Could the difference in AP boot version be causing a problem?  Any suggestions for what I might try next?

 

Thanks.

I'd log it with Aruba TAC and see if you can get a replacement.

 

This looks bad...

 

"Loading: T checksum bad".

 

Thanks.

 

I had this issue once. I resolved it be enabling TFTP Service on the AP and then configured the TFTP Server IP Address on the AP as well (which was my Controller). And then also configured the AP with its Master Controller IP Address. To enable TFTP Service, use the below command:

apboot> setenv bootcmd tftpboot

However, you need to be sure you can reach out to the Controller from your Network.

"T" means bad transmission.  "#" means good transmission.  Something is wrong with the connectivity between your access point and the controller.
