The issue you describe is characteristic for the BMC beep codes. A complete description of these beep codes could be found on the following document: https://www.intel.com/content/dam/support/us/en/documents/motherboards/server/sb/g84364004_s1200v3rp_tps_r1_3.pdf on page 251.
It looks like some sort of power fault either internal caused by the actual power supply unit or external caused by the power input (UPS, facility power system, etc.)
Have you performed any recent hardware changes in the server or any external changes on the power subsystem?
What is the current BIOS version on this server? Has it been updated at any time before?
Let me know
Thank your for your response.
I have not performed any hardware changes for the past two year nor updated BIOS version on this server. BIOS version is S1200RP.86B.03.01.0002.
I have connected two servers to a single UPS and other server is not restarting. Going through the BMC beep codes and your response, it appears that the problem lies with faulty power supply. Is there any way to confirm that power supply is faulty so that I can avail replacement of power supply under warranty?
