Just to double check if you are using an onboard NIC or standalone network adapter?
Can you provide the 6-3 digits (PBA number) on the network adapter if it is standalone NIC. You may refer to this website on wehre to locate the information.
Hello, we managed to fix problem ourself.
Just for the information:
1. Problem with burning nvm gone way only after the full power circle (disconnecting the power cord). It is strange but switching off through ilo didn’t help.
2. Link unavailability was the problem of the router port hang.
Thanks for your help and sorry for the waisted time.
