unable to detect new cpu/memory module

Hi all,

I just add in new cpu/memory module into SFV480 and unable to see new module on slot B. I already try many way like only 1 new module and swap the both module and boot up but still unable to see it.

If I only install the module into slot B, then the server is unbootable at all.

I already change one new centerplane but still the same.

The error show below.

Its either you're not using the correct part OR its not secured properly on the slot, which may show this sort of errors or cause these..
