Hello Andreas,

Thank you for your reply.

Could you please also check Status LED indicators, regarding this troubleshooting guide:

Did you install HD and which?

Is there fan noise when you try to power on server?

It would be also great if you could gather logs from iDRAC and send me it in Private Message.

I would like to check alerts, you asked about.

How to gather logs from iDRAC:

Please ask me if you have any questions,

questions for you:
1. which CPU socket is the processor installed in?
2. can you confirm there are no bent pins in the CPU socket?
3. try removing as many parts as possible from the system, risers, storage controller, integrated nics,           disconnect everything from the storage backplane. 
4. try the PSU in both rear PSU sockets. 
5. also try removing the dimm in A1, the system should still power on, but wont boot normally. 
6. do you have any other models of Dell servers on hand?
The PSU's shouldnt say they are absent.

Hi,

thanks for reply. Here are the answers.

1. Processor is installed in socket 1

2. I haven't checked the socket with a magnifying glass, only a short view. It looked okay, but I will do this yet.

3. Storage controller and integrated nics are installed yet. I will remove they.

4. PSU was tried in both PSU sockets already.

5. Okay, I will make a test with removed DIMM module.

6. I have a R420 available, but there are no components I could exchange for testing.

If I have testet it without DIMM module and storage controller I will give feedback. Thank you very much for your help.

Now I have tried a power on removed DIMM module, risers, storage controller, integrated nics and disconnected storage backplane. Again nothing happend after I pressed down the power button. Also the system fans doesn't turn on. Front display was now showing the following errors:

- The system board Riser 3 cable or interconnect is not connected, or is improperly connected.

- The system board Riser cable or interconnect is not connected, or is improperly connected.

- The NDC is absent.

- The system board Riser 2 cable or interconnect is not connected, or is improperly connected.

Aside from that I've checked the pins of CPU socket. They are fine, I couldn't detect bent pins. With removed CPU a tried another power on and this time additionally the error "CPU 1 is absent" was listed. During these tries with removed components the rear system id LED was static amber.

After reinstall all removed components the system doesn't show the errors anymore. The rear system id LED lights static blue for a while and was turning off then. And the front display lights blue and shows the service tag. But still the system can't be powered on by pressing the power button.

I've noticed that system fan 4 turn on for about 60 seconds after connecting the system to power source. Then it turns off.

With opened chassis I could recognize that two LEDs on the mainboard lights green. There are labels near them with value "DS_LED3" and "DS_3005". I don't know what they indicates, but perhaps someone knows their meaning.

Andreas

Hi, DS_LED3" and "DS_3005, I think these are for our tech support engineers to look at not the users, since it needs opening of the system. It's LEDs WITHIN the mainboard. It's for debugging.

Hi there,

after these tests and because of the log entry RED033 meanwhile I suppose that the system is fine and the power supply is faulty despite it lights static green. PSU lights green also if it is outside of the system and as far as I know a PSU deliveres power on some outlet pins after it is connected to the power source. But only after receiving a power on signal from the system it will deliver power to other outlet pins and the system powers on. Is that right or am I wrong? If that would be right and PSU does not recognize power on signal it would explain that nothing happens if power button is pressed or iDRAC tries to power on the system. Unfortunately I haven't got another PSU in order to test it yet.

Regards

Andreas

Hello Andreas, 

Thank you for your reply. I hope it helps. We will wait for your feedback.

Hello Maria,

thank you very much for your help. Until now I haven't tried the recover steps for bios, because I wanted to wait for log analysis. Unfortunately I haven't the possibility to do this today, but tomorrow afternoon I will do this and give feedback. Thanks again for the great support.

Regards

Andreas

Hello Andreas,

Thank you for logs

I've checked them and found follow errors, you mentioned previously:

2020-12-08 18:24:16        738        PCI1308        A PCI parity error was detected on a component at bus 0 device 5 function 0.

2020-12-08 18:24:14        736        PCI1308        A PCI parity error was detected on a component at bus 0 device 5 function 2.

These alerts are old enough and do not repeat more. I also doesn't see in logs message that BIOS was updated successfully. Did you try troubleshooting steps from the article, I sent you previously?

It also could be great if you could clear SEL logs and after that gather log one more time. At the moment logs contain a lot of old alerts.

How to clear SEL log via iDRAC:

1)To view the SEL, in iDRAC Web interface, go to Maintenance > System Event Log.

2) To clear the logs, click Clear Log.

Hello Maria,

I've tried to restore bios, but without success. It seems that recovery process isn't available on my system with iDRAC8.

I took a look to RAMDAC manual for my system and there is no command "recover" listed.

In the manual I've found another command to rollback bios. I've tried it, but the system couldn't power on.

I think I have to wait until I can test R730 with another power supply. Unfortunately I haven't got the PSU yet. It's my last hope meanwhile. I will give a feedback then.

Regards

Andreas
