NAS540 chassis failure? What's best course of action to recover data or bring online?

Artisane

Wife mentioned to me that she couldn't access our NAS. I checked it from across the room and saw no drive activity. Only LED on the front is the Power. Nothing else. The fan also does not spin. I do have LAN activity for both ports. Canned air got some dust bunnies out, but nothing worrisome. 

I'm afraid its pretty much dead. It was running an 8TB Raid 5 single volume. What are my chances of tossing those drive in another NSS540 chassis and getting everything back up? 

I haven't opened up the enclosure yet to see what the damage is, but it certainly doesn't smell good. No indication that it was overheating or failing. The drives appear to be OK, so its just the raid controller that's essentially shot. 

It can't be simple as buying a new identical enclosure and rebuilding the array, right?

Another 540 or 542 is supposed to accept that array without problems. No extra actions needed. But you'll have to re-create users and re-enable shares, as that data isn't stored on the disks.

(Unless you mean you have 4*8TB disk in raid5 single volume. 16TiB is the maximum size of a volume since firmware 5.10)

That's actually great news. I had a 4x3TB configurations which gave me 8 total in RAID5. Luckily, I had just a very simple share structure, so rebuilding that is no concern. 

Is there much difference between the 540 and 542?

Edit: Any gotchas or things I should be aware of or definitely not do? I've had drives fail enterprise level, but never a SOHO controller before.

The color of the disk holders. That's all.

It's straightforward. Just don't boot the box if you haven't inserted all disks.

I appreciate the help. I just tested all drives and they do spin up when powered in another system (just powered) 99% sure I'll just buy another enclosure and get it all back up and running quickly. Again, thank you for setting me at ease with this. My heart initially sank when I saw it offline.
