DELL T440 Failed
Good morning, I own this T440 which is driving me crazy. I replaced the mainboard, the two XEON Gold 6150 CPUs, and the PIB (practically the entire server). When turning it on it is about to start but after a few seconds (20) on the front panel I have the first symbol on the left flashing amber and the third remaining solid amber. I tried the minimum post, 1 CPU 1 PSU, 1 ram bank on A1. Nothing to do, it doesn't work. I also tried to insert a power supply from a DELL 630 but to no avail, I inserted the two power supplies from the T440 into the 630 and they work correctly. I tried to reset the Bios and NVR via jumper, unsuccessful. I connected the drac to lan port 4 of my fritzbox, entering the fritzbox I see the drac present I see the IP but if I ping nothing responds. I'm literally going crazy.

Hi @Silvano83
The combination of LEDs you mentioned indicates there is an electrical issue at some level, which is a little strange considering you have replaced pretty much the whole system piece by piece.
To the risk of sounding a wee bit offensive... have you double-checked all your cables? Is the PIB correctly wired in?
Is there anything that could be shorting the system? Have you checked the control panel / power button?
Thatäs the only thing I could think of, at this point.

At this point, I disassemble everything and reassemble everything. But it could be a clue, on the motherboard there is a chip called "Lattice" under this chip there are 7 LEDs. When I turn on the server, it starts to start, the fan1 fan runs for about 8/10 seconds and the LEDs under this "Lattice" chip behave like this:
the first two flash, the third remains off, the fourth and fifth remain on steadily, the sixth and seventh remain off. I attach image.

@Silvano83
Those are indeed diagnostic leds, usually referred to as "System board diagnostic LED indicators" on Dell manuals, but unfortunately there is no information for this generation of PowerEdges...
...and each machine has its own codes, so you can't really use a different model's manual to decode what it means.
Basically if something blinks, there is a problem, and it could very well be one of the few things you haven't replaced yet.
LEDs are numbered from right to left, so in your case it would read 7B - 6B - 5off - 4ON - 3ON - 2off - 1off
Perhaps someone working for Dell could have access to some internal documents that could shed some light on this, but so far nobody was able to help with the T440.
