I acquired few HP HSTNS-PF01 units from Flextronics (506077-002, spare 506247-002) and noticed they do not even carry -12V rail any longer. Do some of the modern boards actually require it to start? I have to admit I have not looked after this before, but since there is virtually nothing which needs it anymore, I believe most boards maybe do not even check for the presence of the voltage…?
Than second quiestion, there are Samxons GK on the secondary, some D8, some D10, some D12.5. Is it even worth replacing? I do not think I ever saw any bad caps in any server unit (not even in the failed units) no matter if it was some Ltec or similar crap and after many years of continuous use.
While I can replace the caps, the units are not so complicated to remove the boards, it is not that easy either, and when there is 95% chance (ya remember Fallout? ) that when they'll fail, it will be because of something else…is it even worth the effort? I got multiple of these units…and it is also possible Samxon has improved the series in time, or they at least keep better quality control for customers like Flextronics…
