Dell 730 IDRAC Problem

I have technical problem with one of the 3 R730’s

Please see attached photo of screenshot.

i try this:

1.The easiest way to do this is to hold down the (i) button on the front of the server for more than 15 seconds, this will do a soft reboot of the iDRAC. If the iDRAC is still not responsive after you do this, please power off the server and unplug it for about a minute, while it is unplugged hold the power button in for 10 seconds, this will drain any power from the system so that the iDRAC powers off fully. Once this is done reconnect power to the system and see if the iDRAC is accessible. (NOTHING )

2.F2 doesn´t respond for reset Idrac

3.I remowe PSU,still nothing.

Server is updated to new firmware Idrac,also.

Please advise how to resolve,thank you all.
