The above is for a fairly new IE4010 deployed:

IE4010 Boot Loader (IE4010-HBOOT-M) Version 15.2(4r)EC, RELEASE SOFTWARE (fc1)

xxxxxxxxxnsw02 uptime is 14 weeks, 5 days, 9 hours, 20 minutes
System restarted at 06:26:54 MST Wed Oct 20 2021
System image file is "sdflash:/ie4010-universalk9-mz.152-7.E2/ie4010-universalk9-mz.152-7.E2.bin"

I did a search and found a couple of references about possible old code bug but it is unrelated to this model. There was also a forum posting that talked about incorrect grounding. Just wanted to reach out and see if anyone has seen this before and could point me in the right direction. I don't have a TAC account so unable to open a case with Cisco.

Thanks in advance.

I am currently using 15.2(7)E5 and I do not see this issue.  

I recommend upgrading that IOS and see if it makes any improvements.

incorrect grounding.

yes, this was encountered in other devices which do not proper grounding,  change the source of power and reboot device, and observe, still has an issue, as suggested uplift the IOS and test.

Thanks for taking the time to respond. I'll look for an opportunity to proceed with the suggestions and report back the results.

Any updates on this issue? I have the same problem with an IE-4010 running the recommended version. Can we confirm that it is due to improper grounding, or could it be caused by a malfunction in power supplies PS0 or PS1?
