Hello

When a firmware or BIOS update fails you should drain flea power and clear NVRAM. After doing that try to perform the update again.

Now when I boot, I get an error after the Dell splash screen stating it cannot detect the DRAC

Are you sure that is the message you are receiving? The DRAC and BMC are two different components. The update you performed is for the BMC. The DRAC is not required for the system to function, so the system should not give an error about it not being present since its presence is optional.

Thanks

Thanks for your response.

I was also surprised that this somehow affected the DRAC, however there's is another error that comes up at the same time regarding embedded server management (Can't recall the exact wording atm).

Also I should have mentioned I did clear the NVRAM with jumper, but this seems to of had no impact.

Upon attempting to run the same update in Windows,  the launcher will state that the current version is 0.00 (where initially it said v 2.x).

Further attempts to install this still result in failure.

If the error is in reference to the ESM then that is referring to the BMC and has nothing to do with the DRAC.

If the BMC/ESM is failing to initialize then you cannot update it. Draining flea power and clearing NVRAM will sometimes allow you to overcome initialization issues. If the BMC/ESM still fails to initialize after performing those steps then you will likely need to replace the system board to correct the issue.

Just to verify, clearing the NVRAM involves switching the jumper to the other pin and booting the system and that's all? (The manual just stats to switch jumper and boot but does not specify how long to boot or what to do after).

Yes, let the system boot until it stops. Most systems stop on a blinking cursor. When you move the jumpers you should be disconnecting the power cables. That will drain flea power.

Ok, so unplugged power cables, set the jumper to the "clear" pins, booted up the system and it just goes to Windows after a all of the errors it has been reporting (baseboard management error, DRAC communication failure, DIMM 1 and 5 communication failure).  I feel like it is not clearing the NVRAM.

Note that the DIMM failure messages are intermitten, only seem to occur when the system is booted with the jumper in the "clear" position..

If they only occur with the NVRAM jumper in the clear position then I wouldn't worry about them. If the BMC still fails to initialize then the only other step before parts replacement is minimum to POST. It is unlikely that anything power related changed based on the information you provided, but any USB or PCIe device causing communication or power issues can cause the BMC initialization to fail. Remove all components that you can for testing. If the BMC still fails to initialize then you will need to replace the system board.
