I believe they may be re-badged Trapeze AP's if so then trapeze have issued a bulletin issued on the 24/08/09 that they are admitting responsibility for the high pitched noises coming from the 372 AP’s. They suggest that the AP’s are returned to them and they will either repair or replace these at no cost except for shipping. There is apparently a 3 year span on this.
Others have identified the problem with a faulty 470uf 16V capacitor, which they have replaced with a 35V version. regards garry crothers Nick Allen wrote: > > Does anyone else have whistling 1602 AP's? > We've had quite a few start to emit a whistling noise which if you sit > near one is particularly noticeable and irritating. > We've had 4 replaced already and a quick floor walk shows that another 3 > are also now whistling. > > They're about 3 years old - and all under maintenance so not a big > issue, but it does seem like it could be a recurring issue. > > Nick. > > This e-mail is intended only for the named person or entity to which it > is addressed and > contains valuable business information that is proprietary, privileged, > confidential and/or > otherwise protected from disclosure.
