[rescue] Sun T5240 power supply failure?

Not really talking about different things.
The 3000 has the ability to have two PPS (Peripheral Power Supplies). The base
system comes with just one which also has the mains inlet connector and
switch, p/n is 300-1307 or 300-1400. The 300-1301 was an optional second
backup PPS which you correctly say was used in the other EXX00 systems. If you
open up the 300-1301 and the 300-1307 you will find the same board and can
convert between the two, I have done this several times.
On the 3500 system the second PPS is a different module and is located inside
where the disk slots are.
Glad the Pilots have found a use after so many years in the draw!
On the FC/25, no idea, I too thought it was developed/purchased by Sun and was
a closed system and for-runner to the 1Gb FC product which was generally
available. That is not to say that IBM may have been involved in the
development or supply.
