bl860c i4 Voltage Fault MP sel log

[ThuNDeR34]

Hello.
MP sel log as below occurred on our bl860c i4 server.

Log Entry 934: 09 Sep 2023 18:54:19
Alert Level 5: Critical
Keyword: VOLTAGE_FAULT
Voltage Fault - Check all boards with this voltage.
Logged by: iLO Bay 2
Sensor: Voltage - MEZZ4 PWR
Data1: Performance Lags
B264FCBF5B020721 FFFF010677020400

Occurs when the server is rebooted(planned every 3 months).
I wonder which voltage is faulty.
At first I guessed it was a system board battery, but MP log seem a little different.
Can someone help and analyze it?
We need help.
Thanks.

Thank you for your reply.
I also want to open the case on HPE, but this server contract is currently missing due to a mistake in HPE sales.
I asked because I was curious about the message before completing the additional contract.
Thanks.

@shiva_jr Hi shiva_jr
Thank you for your reply.
This problem has not yet been resolved.
I'm guessing it's a Mezzanine problem, but I can't check any logs and status other than that message.
I don't have document link permission, so please let me know what the document title is.

Thank you.
