Hi,
I have a ML 570 G3 with 4 Xeon cores, full redundant PSU, 12GB RAM. I got it as a refurbished unit and it worked well until yesterday when it started acting very strange. It powered down by it's own ( Front panel power led AMBER) no red fault led. Both PSU have green led flashing meaning PSU on standby. If I remove both power cords and leave the unit for few minutes, when I plug in the cords it will try to power up, spin the fans and then stop again to standby. No internal faults are shown on the 2 digit display. Sometimes the server powers up for a few minutes or even half an hour but then it simply goes back to standby without any obvious fault.
Tried removing all addon cards ( 2 SCSI 6400) and additional memory boards and leave only CPU1 and PPM but no success. Both PSU's appear to be in good condition and the server worked fine for the last 2 years. No signs of swollen or broken caps, cables look OK, removed all components up to SCSI boards, backplane power card, front panel, everything seems to be OK. Tried to reset NVRAM, clear all config, nothing. Server keeps acting strange. Can someone point me to the right direction? It is a backup machine so it is not critical( yet) but I would like to have it up and running.
Thank you.
