Thanks Anusha for the info. Do you have any more details on how to enable the himem logs ? I will open a support case but have several APs exhibiting similar behavior, all at a single site and all with the same type of switch.
Thanks Anusha. Will open a case and point to this info. In the past, I was asked to RMA the AP but such a log was never taken.
Power is indeed one of my suspicion as the APs where we see this the most often are those on longest cable runs. I was expecting to see the "brown out" alarm but then I noticed the R510 does not support such an alarm. I guess it's for AC powered APs.
