MAC Address & logs

[04mradzi]

Hi guys

I,ve got a quick question about the MAC address and logs. I've sent my TS-879U-RP to QNAP Service due to a backplane failure. It came back but nothing has changed - still doesn't work.
They had sent me an expertise with a snapshot showing that everything is now ok. I can see a MAC address ther but it differs. Mine is 00-08-9B-CF-02-17 and on the paper the last two digitis are 16! Is it possible that they change the LAN card with MAC address almost indentical? And when it comes to logs - there are only my logs - before sending the NAS and from today. Is it all possible?

Thank you for you help.

Best regars,
Michal

It's more likely that's the MAC address of another network interface on the same board. It looks like your model has at least two.

And when it comes to logs - there are only my logs - before sending the NAS and from today. Is it all possible?

They probably didn't boot it with your drives for testing / service, even if you sent it with drives - so yes, quite possible.
