I have a problem with an HP Proliant DL380 G7 that leaves me without much in the way of troubleshooting approaches.
This server will not boot. It was stored in a datacenter, and I went to retrieve it after I could not connect and the colo tech couldn't hard reboot it. It would basically flash all HDD and system health lights, and I unplugged the system after I could not access it or restart it by pressing and holding the power button. Since then, it does nothing and just sits with the Power LED solid orange, and no activity on the health lights. The fans don't spin, the power supplies don't light up, nothing happens.
I unplugged all of the drives and just tried to boot with the CPU and memory, but still nothing. The ethernet link lights do light up, though. The system has dual processors and two power supplies. It seems like a motherboard error but I can't tell.
One person mentioned the PSU back planes fail sometimes, and that makes sense, but plugging in only one power supply and checking every configuration possibility produces the same result.
The server is out of warranty and I need to find which part to replace. Is there anyway to continue troubleshooting it? The system has iLO installed but I don't know how to access it without being able to boot the machine to BIOS.
