I have a PowerEdge R330 that was working fine until last few days, when an error message like this one appears:

"UEFI006: A PCIe link training failure is observed in NDC NIC 1 and the link is disabled. The system has halted".

After this, the only thing that I can do is reboot the server, to get again the same error.
I can't even access to BIOS or iDRAC to check system configuration.

Thanks for your comments, I'll appreciate it
