Hi there,
In recent time, we noticed that our Prime server is down and we noticed the host is power off during inspection. I am trying to poweron the host but it is automatically switching off.
I found this log in the CIMC. Is there any recomendation to recover this?

I do not think the log entries you published give indication to a problem ("normal" dos not sound as an error does it?)
MAIN_PWR_PRS just means means main power present!
how did you perform this power-on ?
1) did you just plug-in the power-cord ? then only the CIMC (instant management controller) this is a aditional microprocessor separate from the main computer that performs some basic hardware tests and configuration.
-> you need to assert the power button at the front to actually power on and boot the main processor.

2) did you power on using the CIMC ? (using the tab power-management visible in your screenshot)
then maybe something is blocking the power-button
in the CIMC you can configure if the main computer should automatically bootup after external power is connected (default is off)

Hi Pieterh,
The server worked as expected earlier and suddenly we noticed this server is down. While inspecting, I noticed that the host is switched off.
1. I did try to power on from the CIMC console. I was monitoring the vKVM output and it suddenly switches off.
2. I switched off and recycled the power using the botton at the front.
Still, I am facing the same error.

Then you need to further inspect the CIMC logs.
As said your extracted info gives no info.
Check the tab about inventory to see if all hardware is reported present.
And you can start some diagnostics from the CIMC.
Opening a Cisco TAC case can be an additional step.
