I bought an old HP DL380 G4 off ebay last week, and the past two nights it has shut down by itself.
In iLO, it shows Server power removed, and Server reset at the same timestamp over night and the last two times I have been able to go up and press the power button to fire it back up. This morning I show up and it was down again, so I press the button, but this time the front LED for power turns red which means power failure. The two power supplies have a LED on them that typically is green, but now they are not on at all. I have tried pulling them, re-seating all the components, swapping the two power supplies back and forth, and new power cords. The AC power connected light on the PCI riser is lit green. I opened it up and checked all the internal LED's and the ones that were on were all showing green, then when I press the power button all the fans spin and the rest of the LED's shine for a split second like its going to power up, but then it all shuts back down and I cannot get into iLO until I pull the power and reconnect it, but not press the power button. I'm lost as to what to try next, I would assume that the power supplies are good since I can get into iLO, but the problem is related to power... I read about issues with the PPM, but I have two since its a dual CPU setup, so I swapped them and configured it for a single CPU setup and still no luck... Any chance any of you have messed with this? |

try just one power supply. or the main board is bad. how are capacitors? Tried both of them, then swapped back and forth, then tried each one individually in each slot, no luck. I haven't tested the caps or even an output voltage from the PSUs, I'll do that next time I am with the server. |

Several things here since the HP gear is 90% of what I deal with here at work....
1. Try only one PSU 2. pull 1 psu and try swapping the Voltage Regulator unit if that works hot swap back in the second PSU and you should be GTG 3. VRU may be intergrated into system board in whcih case you may have to replace the sys brd |

I'm no server guy, but the last time I had janky power issues in a computer with otherwise known-good parts, the problem ended up being a worn out, shorting power switch flipping the damn thing on and off constantly. If the PSUs are good, maybe check that. No power switch on these guys, thanks tho. Quoted:

I'm assuming the PPM is the same as a VRU, just a different name for a different generation. The only thing that I don't have two of in the power system is the system board, and the DC converter module, so I ordered the DC converter module and if that doesn't work I'll get a new system board coming. Hopefully its not a situation where both PSU's or PPM's are fried... Thanks for the help so far guys. |
