HEllo managers, I have a very strange case.

I recently installed two more processors with their correspondig DCDC on
a E450.

The power on the machine with no problem , same day 1 hour later I was
asked to replace the existing DDS3 tape reader which was causing trouble
with a new DDS3.

I replace the DDS3 but now the machine doesnt power up, or power on.
I reassembly everithing in place, all covers, every screw but the
machine doesnt power up.
The power plug is connected, the key switch is to off the to on and
nothing, also connected the keyboard and repeat the steps and press the
power button, and nothing not even the fans start.

??? WHAT IS IT ?? i remove the new DCDC and the CPUS, nothing. I
reinstall them, the same, remove cards, disks, but nothing.

I check docs.sun.com at
http://docs.sun.com/db/doc/805-0429-10/6j0fk0g44?q=power+supply&a=view

The only thing that Ive notice is that the 3er led (from left to right)
on the power supply, the DC status is always off, anyone has ever seen
anithing like this.

The machine warranty time is over I ask sun for a time and material
report but are very slow, any ideas ? how can I identify the failure
component ?

I WILL SUMMARIZE ! Thanks !
