  How many PSUs are installed in the Poweredge server? In the manual it says it could be 1 or 2 and the power per PSU could be 1100W so if it is 2 * 1100W then that could explain why the UPS has problems with it.

  leaded solder without an extractor fan

  lead does not vaporize at the temps used in soldering.
  lead free solder also needs fume extraction. even more so actually, because it is used at slightly higher temps. even with perfect fume extraction, leaded solder can still poison you, because you touch it and then touch your face without washing your hands.
  if you are prone to allergic reactions from solder fumes avoid solder with a rosin core, use synthetic flux instead.

  I think you can even draw a defining distinction there because if it is not believed then pseudohalucination would be the better description.

  If you mean an Immune escape that is not a real problem for rabies becuase that virus has a slow evolution as you can tell from the fact that the same vaccines that were used in the 80s are still used today. Compare that for example to flu or Covid-19 vaccines where even two year old vaccine types are considered outdated and not used anymore.

  That is probably inspired by EN IEC 81346-2 where “X” indicates a connector of some kind and the numbers following the X identify the connector and the relative position on the connector (for connectors with multiple contacts).

  There is a limit on the spacing of the colour bands though. If you want colours then you have to hit the spots where the correct phosphors are and this limits the usable resolution.

  trains are actually one of the examples where you can get away with lower energy dense fuels, like methanol, ammonia or even compressed hydrogen. sure the range will go down, but for many connections this will not matter that much because it will still be possible to go 1000km with one tank if needed.
