[rescue] Sun T5240 power supply failure?

[Peter Stokes]

Hi Jerry

Interesting issue with the T1000, I found the older version of the T1000 had a
tighter tolerance on the voltage levels and with a later PSU could show faults
even though within tolerance on the later T1000 configuration. The T1000 PSU
was however not that good and had a few failures on them either as bought in
used or failed on the bench.
