Blade's iLO MAC address is null - UUID is null

[Jayooin]

Hello,

Following this post :http://community.hpe.com/t5/HPE-BladeSystem/Blade-can-t-be-powered-on/td-p/6835852 , I've changed the motherboard again.
Now it does boot (for now), but there are information missing:
1. NIC iLO port is 00:00:00:00:00
2. UUID is also set to 0
3. Serial Number is empty
4. Part Number is empty.

You can see that (iLO MAC) in the attached screenshot

What's wrong with my system?
Did anyone experience this kind of trouble as well? How can it be fixed?

Thanks for any answer.
