HP ProLiant ML350 G6 Server - Not powering ON and No LED Lights

[Sagar_Bng]

Server doesn't boot up and there is no power, LED lights doesn't glow after powering on the server.

When the power cable is connected, no LED light gets on (neither in the rear or front lights)

Pressing the power button does not bring any LED lights on.

Only power supply fans started to spin and stops when power was plugged in, but power supply LEDs did not light up.

The power supply unit works fine and tried to swap with another working server of same model, and the Power supply works in that server, but will not work in this server.

Please provide a solution for this

Hi Sebasbin,

I have already done the steps as per your suggestions, but still there was no power indication in the motherboard nor the LED lights (front and rear).  Still the issue has not been resolved, and I am finding it as a peculiar problem. I am planning to check for the replacement of power backpane.
