Cannot be RAID 10 with 2 Hard drives, you need at least 4 for RAID 10, can be raid 1 (Mirror) or RAID 0 (JBOD). Dell Lights, I am assuming you mean light 5 is amber, how about the 1/2/3/4 lights?
Light 3       Possible Processor Failure
Light 3/4     Memory Failure
Light 2       Possible Expansion Card Failure
Light 2/4     Possible Video Failure
Light 2/3     Hard Drive Failure
Light 2/3/4   Possible USB Failure
Light 1       No Memory Modules Detected
Light 1/3     Memory Configuration Error
Light 1/4     System Board Failure
Light 1/3/4   System Board Resource/System Board Failure
Light 1/2     System Resource Configuration Error
Light 1/2/3   Other Failure

the amber light on the back is the same as the amber light on the front

Push the button on the front with the cursive ' i ' ... does it stop blinking? Sounds like your "identify" light is on.

PowerEdgeTechIT ConsultantCommented:
As for the error ... there should be a description with the 0xC4 error code, like "BIOS shutdown test failure" or "BIOS POST memory test failure" ... either way, it sounds like you likely have a failed motherboard. You could try clearing the NVRAM using the jumpers on the motherboard to see if that helps, but you are probably looking at moving to a new server or replacing parts.

1. The server isn't accessible for troubleshooting till Wednesday morning.
2. The problem (0x000000C4 error code) coexist with Meltdown / Spectra update from MS applied to this machine, but might be not related???

Was that the last thing that was done before the problem started? Which antivirus was on the system?

You are talking about a Windows 0x000000C4 error, not a POST/BIOS error?

masnrockCommented:
The better question is what type of processor does your system have? It sounds like you got bit by the issues with some of the AMD processors. Microsoft blocked that patch for a bunch of systems with the AMD chips. You're going to need someone to get that system into the Recover Console to fix (I assume it won't go into Safe Mode).

I think masnrock has nailed it; that server uses older Opteron processors and would definitely be hit by the bug in Microsoft's update.
But; there is a different question, that PC was tested for Server 2003 by Dell and I don't think you can do much of anything with DISM if it is running 2003.  What version of the O/S is running?

I was under the impression that server OS patches for these flaws were not going to be available for quite some time.

1. Windows 2012R2.

2.  0x000000C4  (+ 4 rows of #'s & letters) looks like POST/BIOS error, it shows up on black screen 10 sec after turning ON the server.

3. Tried DISM, it can't find the image.

What the author left out of that article is to start the Recovery Console and type DIR C:<enter> then DIR D:<enter>, etcetera to find the drive letter which has Windows installed and that folder will appear in the list when you find the right one.
Once you have found it, here is an article on how to list the installed updates:
https://docs.microsoft.com/en-us/windows-hardware/manufacture/desktop/take-inventory-of-an-image-or-component-using-dism#getpackageinformation
I think you need to start with dism /online /get-packages to get a list of the updates and then figure out what the command line needs to be to uninstall the latest KB.

Here is another article so you can limit the updates listed to the past 15 days:

error on boot

Davis McCarnOwnerCommented:
Bud, I hate to say it; but, you have no choice but to figure out most of this on your own.
You're going to need to boot into the Recovery environment, use DISM to get a list of the recent updates, Google search the KB numbers to see which one is the one that kills older AMD CPU's, and then use DISM again to uninstall it.  The article that masnrock posted is for Windows 7 or 2008 and you are running 2012 so the KB number in that article is wrong.

That article said you needed to create a \temp folder and then add the /scratchdir: <driveletter>:\temp to the command.

David Johnson, CD, MVPOwnerCommented:
it is KB4056898 that is problematic
Microsoft has rolled out a fix

you will have to boot from installation media to remove KB4056898
