Hi,
We have a fairly large (60+) [brand name excluded] PA speaker and adapter deployment connected almost exclusively to MS switches.
We're finding a number of them dropping off from time to time, requiring diode replacement to fix. The retailer and upstream are baffled as to why this is happening, as these appear to be rare (for them), and we are being asked what injectors we're using, any power issues, etc.
The vendor and reseller have been gracious about it and the reseller has been ordering parts and repairing them for no cost, despite some being out of warranty and so on. We don't expect this level of service, but are thankful for it.
We are using only line-interactive UPSes for the majority of our switches, and do have our share of power outages.
Any thoughts, shared experiences?
The MS225 data sheet, for example, makes no claim to any power conditioning, filtering, whatever, although we would've liked something to be mentioned (either way).
Thanks,
shaakir
