Replacing a fan on XG-1541 1U
I have purchased XG-1541 1U over a year ago. It is not high-redundancy unit, i.e., it does not have dual redundant swappable power supplies. And the fan on the power supply is on 24/7/365. So no matter how good the fan bearings are at some point the fan will fail. If I don't want to wait until that moment, but would like to replace the fan (with the same quality unit) what are my options? The case is sealed, but I am not sure how long the hardware warranty is for. So when should I be able to open it and replace the fan? And also, does Netgate recommend any particular fan model? Or do they recommend some other approach?
It's impossible for us to recommend you open the power supply. I could only suggest you get a replacement identical PSU if you need to replace a worn fan there and it's out of warranty.

Confirm that physically before ordering though since I don't have access to check directly.
