    S1400FP4 ac on power supply = solid amber Status LED + blinking blue ID LED - can't find anything about this combination


      Dear community,


      finally I got some time to setup my 2 years old  S1400FP4 mainboard into a server.

      After finishing cpu, cooler, fans, some ram and the power supply I started a first boot for testing but "nothing" happened.

      There was no boot screen on the monitor only the fans were running. So I disconnected every unnecessary fan cables, usb connector, power led and tried again.

      Nothing. So I took out all 6 memory modules and put in another vendor module from my workstation. Again nothing.

      I can see and hear that the be quiet power supply is working (has 2 fans and the fans of the cpu cooler are also running.

      After thinking about a reason some blinking led got my attention. So I checked the manual for some hints about it.

      But this combination is not mentioned.

      It is still irrelevant if I power up the server (with or without ram) or if I just switch on only the power supply. There is always the same behavior:

      Connecting the power supply to the AC and switch it on:


      Solid amber Status LED and the solid green 5VSB LED for max. 1/2 sec. .

      Then a very very very fast blinking blue ID LED, all solid amber RAM LEDs and some other solid amber Status LEDs on the mainboard for ~1 sec. .

      After that the solid amber Status LED again with a fast blinking blue ID LED (and the solid green 5VSB LED).

      After ~7 sec. the blue ID LED goes off for ~2 sec. and then the very very very fast blinking blue for ~1/2 sec. again and then the fast blinking like before.

      Then nothing changes anymore - solid amber Status LED + fast blinking blue ID LED.

      If I press the power button of the chassis now only the fans of the power supply and the cpu cooler are starting. There is no effect on the LEDs.


      Would be nice if someone can give me a hint or a little push in the right direction.


      PS: I didn't change the power supply against the one in my workstation right now...
