first of all thanks for your reply.

no any update was before this issue, only one thing, the power was cut off from main breaker and put back during the server plugged.

my troubleshooting was how to reset the IDRAC from I button and also i power off the server and unplug it for about a minute, while it is unplugged hold the power button in for 2 minute but nothing change. 

Is BIOS accessible?
yes the BIOS accessible.

Is iDRAC pingable?
no Isn't iDRAC pingable.

Can you access to LCC?
I can't access to LCC because IDRAC isn't pingable.
