Hello,

I got a dell R420 was shipped with single cpu (e5-2420v2) as list here :

my st :

And I see that there are 2 riser card on the board.

Yesterday I plug in a new one e5-2420v2 (with heatsink and fan) to run dual cpu. The system boot fine, I can now access the OS as normal and can see 24 cores.

But the lcd screen in-front-of the server change from green to orange with warning : HWC2005 system board riser cable or interconnect failure ...

How can I fix this ? is this dangerous ?

Plz show advices.

Thank you and Brs.
