Geeez the people of this list are awesome, thanks to: Matthew Stier <Matthew.Stier@fnc.fujitsu.com> Sean Berry <berry@housebsd.org Greg Hanks <Ghanks@ghanksdesign.com> Jayashankar Nelamane Srinivasarao <jayashankar.nelamane@wipro.com> Colin Bigam <colin.bigam@west.gecems.com> 4jet@overnite.com Specially to: Pascal Grostabussiat <pascal@azoria.com> who was kind enough for a more detail schematic help The Answer in brief by Greg Hanks: The cover in the rear engages two different micro switches. These switches are very delicate, but disable the power. Look carefully at them and ensure that the little plastic points on the cover engage the switches. If in question, unscrew them through the access holes on the side rails, remove the micro switches and ensure that the actuateing levers are in the proper location. These bend easily so be careful. I Think is a tipicall murphys law case: A switch of 50 cents. make a 15k dollar machine not to work. Thanks again to all of you ! The original post is below !

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 !
