PowerEdge R720 stuck at CPLD

Hello

If the system is not completing POST then you should go through no POST troubleshooting.

https://www.dell.com/support/article/sln111201/

The issue isn't necessarily with CPLD. The issue is likely with something after CPLD. I would try to fault isolate by removing hardware. I would start with simple things, like external USB.

Thanks

Ok, so i did everything to troubleshoot no POST again. Brought the server to minimum to POST, left only CPU #1, one memory module in A1, took out the PERC H710 mini controller and even intel network card. No USB devices, no nothing, even no display connected (i'm using iDRAC's virtual console). Here's the screenshot:

Cleared NVRAM using the jumper as it's suggested in hw manual. Nothing has changed.

Is that it? Out of ideas, no more support, silence is golden? I've been told Dell support is a joke, but frankly, i've had no idea, it's such a bad joke. Well, i guess i'll have to get back to ProLiants. No more PowerEdges. Thanks, but no thanks. :)

I have the same problem. After updating the BIOS, the server crashed at the same point. POST initialization has not been completed. Does anyone have any idea what I can do?

Hello,

What troubleshooting have you taken thus far? Have you checked out the article in the response regarding no POST troubleshooting?

I have the same problem.  I have tried all the recommended troubleshooting guides to no avail.

Any more suggestions?

Hi, can we make sure one more time these conditions are met?

PowerEdge R720 Minimum To Post 

·       One Power Supply

·       Control Panel (for power button functionality)

·       Working cable connection between control panel and system board

·       One Processor (CPU) in socket CPU1 (minimum for troubleshooting)

·       One Memory Module (DIMM) installed in socket A1

·       System Board

·       Backplane 

iF Should you still see the issue,  best to get in touch with the phone support at this point, I might recommend. Thank you for your enquiries and have a great one!

Please read the thread.  We have done everything you and dell support have recommended.

No solution.  No progress.

Any way for F2, F10 or F11 to execute before POST completes?

Are you seeing your system hang at the CPLD, or are you also seeing the missing network card message? Servers can stop at the CPLD section for a variety of reasons and knowing if you're getting the same message may be helpful.

If you've already tried all recommended steps, I would have to recommend replacing the motherboard. I'm happy to make troubleshooting suggestions, but I would need to know what you've done. You may well be right when you say that you've tried everything, but in the case that there is something I can suggest, I would need to know what's already been tried. A brief description should be sufficient.

020HJ is the latest part number I'm seeing for the motherboard service kit. I'm looking at the block diagram of the board now, and it confirms the CPLD as part of it. If you're confident that all troubleshooting steps have been taken, than this is what I'd look at next.

When configured as designed, my system boots without errors and then hangs at the CPLD.

When I clear the NVRAM, I boot and without errors I get to the prompt to press F1 or F2.  At this point the system is unresponsive.

When I clear the NVRAM, I have tried booting without any keyboard, mouse or any device in the USB ports.  When I get to the prompt to press F1 or F2, I plug the keyboard into the USB port and the system is unresponsive.  I have repeated this for each USB port.

Is there a way to disable the CPLD?

To the best of my knowledge, the CPLD cannot be disabled. However, referring back to this diagram, it looks like it is only connected to the iDRAC. If flashing the iDRAC didn't work, the only other suggestion I could make is to try disabling the Lifecycle controller (LCC). It's a bit of a longshot, but it's the only thing I can think of that you can fully turn off. Now, the LCC data is on  eMMC storage separate from the iDRAC and CPLD both, so I just want to reiterate that this may not move the needle at all, but may be worth testing.

The way that I know to turn the LCC off is to SSH into the iDRAC and issue this command:

$ racadm set LifecycleController.LCAttributes.LifecycleControllerState 0

Was the server at a minimum to POST configuration when you tried these different approaches? If so, that would really have me looking at the motherboard for replacement.

How did you solve the problem?

Hello, cpearson22033, just checking if this case has come to any conclusions. Wish you a great holiday ahead.

Just go to System -> Misc -> and turn off reporting Errors (right under keyboard errors.)
