Hi,

What are the files need to be edit after replacing with new system board. Because of big environment we do this activity on weekly basis.

Clarify what you are talking about. Do you mean a motherboard or a kind systems management board? Also, there is not just some text files to edit to have this working. There is also no precise recipe to get your stuff running again.
Try it on some testbox and write down the actions you do to get it working again. If you are lucky, there might not be much to do after replacement.
Have working backups of the machines you work on.

Ask an experienced co-worker to assist you or assist him. Read the hardware documentation for such service tasks if available, get familiar with your hardware and Linux.

Thanks for quick reply.

I mean it is a system board. where do we need to update( files) this new system board information. we don't have any textbox.

This description is not better, sorry. What I wrote still applies, even if it is some kind of firmware update.

Naveen ,

Verify the MAC address of the Onboard interfaces they will change after your replace the systemboard.
