You can have the same problem in the bigger Ultra-2 based
sparc64 machines too.  The motherboard in the Ultra60 (aka Netra 112x)
has 4 PCI slots.  Only one of those slots supplies 3.3 volt
power, while all four slots provide 5 volt power.

So, you have to plan your PCI card insertion carefully, and make
sure you have no more than one 3.3 volt card, if you are putting
multiple PCI cards into one of those machines.
