rp8400 doesnt turn on

Dear all,

there was an issue with the core I/O card , mp lan was not responding and serial console was not showing anything. So i had to replace the I/O card. in order to replace the I/O card i turn off the operation system, than replace the I/O card, but still nothing , even new card was not responding in the console. furthermore the led indication on the front view was alway on (MP present) even when i removed the core i/o. so i had the power off the server and than the supprised happend, the server does not turn on now. Only standby power led is on, the power supply leds are blinking in green and also the front fans led are blinking in red  continuously.
Any idea/suggestions about the situations?

Thank you in advance.

Any response from the second MP card?

Even if the server does not power on, the active MP card should log about the reason for the issue.

Could even be a problem with a VRM or anything ... logs would be important.

Hope this helps!

 Hi Ramana,

I dont think it could be problem of the fans , how could they all gone failed at once, they were working, and after we shutdown the server the issue occurred.

Hello Torste,

The server has only 1 MP card and tried in both slots but no response at all. it is a bit strange that MP doesnt not log enything....
