I thought it might have been because I upgrade the iDrac from an old version to the latest, without components like the BIOS or NIC, that the iDrac communicates with, being upgraded as well. After upgrading everything, iDrac still was not working, after a few days of messing with it, I found out through piecing together several sites how to force the iDrac in recovery mode to do a TFTP repair, writing a new image to it.

The symptoms : The system used the Windows iDrac Updater, which stated the update had competed successfully. I then, remotely, told the system to reboot; it shut down and never came back up. Press F1 to continue, or F2 for System Setup. Then the system would go through normal boot sequence, but when it tried to communicate with the iDrac it would fail then restart the server.

Thus the server would not boot without physical intervention at the machine. Update September : I wanted to signal boost some of the comments below, if you have a 12th gen system with a SD card slot then the following may be the best path forward. Thanks Simon! The flashing light should turn solid and 5 or so minutes later iDRAC should be back up and running. Thanks you saved my day!

To fix it, I installed a windows server evaluation to see if the windows solutions worked.

There are quit some people having a issue with drac with no working solution. Did the serial settings give you any luck? I was thinking you could go into Device Manager on Windows and see what serial ports it is giving you. Perhaps for some reason it is creating COM3 or something similar? And sure enough, It is. Hi, im so glad to find this article.Your repair repertoire should also include a couple of additional procedures that can occasionally eliminate otherwise inscrutable problems—zapping the NVRAM and resetting the SMC.

If the values in this memory got out of whack for one reason or another, your Mac might not start up correctly, or might exhibit any of numerous odd behaviors afterward. NVRAM serves approximately the same purpose as PRAM, but instead of storing a dozen or more pieces of information, it now contains just a few: your selected startup disk, speaker volume, screen resolution, time zone, and—if your Mac has crashed recently—details of the last kernel panic.

Keep holding down those keys for about 20 seconds. Then let go and allow your Mac to continue starting normally.

If you have an older Mac that chimes at boot, hold down the keys until you hear a second startup chime. You can see a longer list on this Apple support page.

On the built-in keyboard, press and hold the Shift, Option, and Control keys on the left side and press the power button and hold all of these down for 10 seconds, then release the keys.

I would probably try sending those in for repair to have them flashed offline. As long as both power supplies are the same wattage, you will be fine. Just do not try to use one of each.
