To my assumption (without any documented information, I can't be sure), the BIST button completes the circuitry of the SMPS (PSU) and it manages to supply power to the mainboard. I would recommend trying replacing the PSU first. I won't rule out mainboard as the root cause.
The 2,2 amber light is indicating an issue with the systemboard, the power supply, or the power supply cabling. So what I would suggest you start with is taking the server to its minimum to Post configuration to see if it posts normally, if so then individually add the removed parts back until the issue reappears, which helps in identifying the cause of the failure.
Minimum to post on the T30 is removing everything internally and externally from the server, but the following;
System board Power supply unit Processor (CPU) One Memory Module (DIMM) installed in socket A1
Again if it starts up then power down and one at a time add the devices back until the issue is replicated, or everything is reinstalled.
If it fails to post under the minimum to post configuration then the issue is with one of the devices I listed above, and if you have another T30 I would suggest testing with known good replacements from it, until you identify the cause of the failure.
When the BIST switch of the smps is kept pressed the machine runs all right. As soon as it is released the machine turns off. So mobo, processor or ram could not be an issue but the smps might be faulty. What do you think?
Yes the machine starts all right with the BIST button pressed with the control panel is removed. On screen shows control panel is open. Machine starts without power button but only with the BIST button!
I would not say it's the DIMM or Processor. The mainboard would be the least likely amongst the cause of the issue, but cannot be ruled out. When the BIST button is pressed, do you need to press the power button at the front to turn on the sever, or it's not necessary? I would recommend trying what Chris mention removing the components other than the listed and try narrow down the issue. I would also check if the power button is stuck. Try disconnecting the control panel (if the BIST button is pressed and the server turns on itself without the power button)

Let me know what you see.
