TS-451 Backplane Replacement

[dedwards180]

Hello,
Our TS451 nas has a faulty SATA interface, we've lost one drive out of 4. If a drive is plugged in, it attempts to spin up the disk, and then reports and error. I've traced this down to one of the SATA controllers on the backplane having failed, the switching FETs are OK. The channel failed during some thermal testing we were doing, and the unit was running in an ambient of 35+C.

Does anyone know if it is possible to purchase a replacement backplane card? PS TS-451 BP1.0

Thanks
Dave

Qnap don't sell spare parts and they will quote you a very high price for sending the NAS in and have the mainboard replaced (that is if they still even have some spare parts left for that relatively old unit).

The only way go get a spare part is on the used market, like Ebay or whatever is available to you. Your other options are to repair the backplane or to buy a new Qnap that support migrating the disks over.

Hi Dave,

I know this is an old post but I'm having an issue with my backplane in the ts-451+ at least I believe it is the backplane that is the point of failure!

May I ask if you found a solution for your backplane issue that didn't involve buying a new one lol?

Thanks, sir all the best

Alex
