There is a section in the manual that explains the diagnostic indicators. Page 19 has information about a flashing green light on a PSU. It indicates the power supplies are mismatched. Either the power supplies are different or the input voltage is different between them.
If the issue persists after swapping power supplies, verifying input voltage, and verifying the power supplies are the same then the issue is likely with another component in the power subsystem. The power supplies are auto-ranging, so if the input voltage is outside of range tolerance then the two power supplies will be mismatched. For instance, if one PSU is receiving 120v and the other is receiving 105v it will likely cause a mismatch.
The next likely component would be the power distribution board. The power distribution board is integrated into the system board in many of our newer servers. The power distribution board is what the power supplies connect to inside the server. If they connect directly to the system board then the PDB is integrated.
