Hi a.basharat, 

Based on your statement "A ticket was opened with F5 to troubleshoot this together, and on a very early stage they decided to RMA the F5 as they said it looks like a Hardware failure."

After this, does the Power On issue after power loss was resolved to the new F5 box?

Thank  you

    Yes all went fine with the new RMA box. Just one more suggestion to add, when you power down the Host [i5800], make sure all the guest running on it are on Configured Mode, otherwise they might get damaged
