Flashing Red Lights - No Power

My Cloud OS 5 Personal & Network Attached Storage My Cloud Pro Series

Hi there,

I have a PR4100 which all of a sudden, just lost power and then wouldn’t power back on. After disconnecting the power cable, letting it sit overnight with nothing attached and reconnecting it, the NAS just blinks it’s 4 red disk lights over and over simultaneously (about once a second) and but doesn’t appear to switch on. Has anyone seen this before? Any ideas what it means?

Cheers,
Ross

I have had a few NAS power units go bad on me in the past

if you are careful you may find PC laptop power units of the same voltage/amp and plug
or better yet a WD replacement power supply
