Troubleshooting Omron Sysmac CJ2M CPU33 Error with 24v PSU Supply Issues

Question:

Hello, I am seeking assistance with a customer's CPU experiencing issues with the 24v PSU supply and now displaying an error state. I am unfamiliar with this system, so any guidance would be greatly appreciated. The CPU is showing error codes ER E1 IP 2 with a solid green Run LED, solid green MS LED, and flashing red NS LED. The PLC rack also contains module NX-EIC202 with only the I/O Power LED illuminated in green. Any insights or advice on troubleshooting would be helpful.
