F5-221 - shut down. No power led.

Removed all HDD and checked power. The unit starts with 1 HDD, shuts down if I add a 2nd.

However when I checked power adapter it makes a strange hissing noise with 1 HDD - and a constant click if NAS off.

I therefore conclude it is a power adapter failure.

Do u provide replacement in EU? Ty.
