ML350 G4 Power supply LEDs

ML350 G4 won't power up. Front panel power light is Amber. Power LED on motherboard is Green. I connect 120 VAC power cords to either (or both) power supplies and I hear the power supply's internal fan running  but the LED on the power supply next to the power cord socket is *NOT* lit. Nothing happens when I press the power button - no post, no beep, no fans other than the power supply fans.

 

QUESTION: Should the power supply LEDs be lit ALL the time, or only when the system is running ?

Hi,

Possible cause a faulty Power Supply.,a faulty Power On switch

  • Swap with known good PSU.
  • Swap with known good power cables.
  • Try with minimum configuration like one processor and one set of RAM.
  • Remove the power to the server for couple of minutes and connect again to check.
