During preventive maintainace we Power Off Secondary connectivity server & after cleaning we again power ON Secondary connectivity server.But its not Boot & we also checked NIC Card,Hard disk,RAM all are found ok than we replace mother board & found Secondary connectivity made ok.after few days we again check faulty motherboard & found faulty motherboard now working ok.What is reason for Motherboard???
One time its not boot & after few days its working normal.
You are using servers of which make (model) DELL or HP ?
I suggest you to run diagnostics like DSET in dell servers or its counterpart(HP system management software) in HP servers(if you are serving HP servers)
You will get insights of current hardware status and history status logs of servers,for further analysis, you can share diagnostics reports with Concerened OEMs.
