I have only one power suply (non redundant) and when plug it to wall, it start with green in AC , yellow (alarm) and off to the "power supply status"
Then, it starts and when cool calibrating proccess (when FAN coolers speed up) it shut off.
And stay in green at AC, yellow at (!), green at power button (on the front controller) and slow blinking blue LCD screen.
But no error message or anything to guide to solution...
The problem is at the Power Supply? At the Motherboard? At the FAN coolers?
Anybody has the same problem or the solution?
I d check the power supply out the server, power on it, and measure with multimeter: 12,2 Volt without any compsumption. And it stay "ON" and without yellow led (off)
