I had a user report that the IAP-305 in a classroom was making a high-pitched 'whistling' noise - by the time I got there to investigate the noise had stopped. The LEDs looked normal and the web interface and Airwave both showed the IAP up and connecting clients with no abnormal readings jumping out.
I'm not completely sure the sound came from the IAP - I wasn't there when it happened - but is it possible that these devices would sound an audible alert in some circumstance? In all the years we've been using them I've never experienced that.
Thanks.
