I'm running a 9406-170 with a 9910-080 UPS. recently the system powered down hard and would not power back up and the UPS powered off as well. When i reset the ups and attempt to re-ipl the system, the system starts to ipl and then there is a clicking noise in the ups and everything shuts down again. I removed the UPS from the power sequence and plugged the AS/400 directly to the wall outlets and it IPL'd and is running fine.
Do I need to replace the batteries, the UPS or is there a setting on the system i need to change? It seems to me that even if the batteries on the UPS are no good, the power should passthru and the system should IPL.
Software/Hardware used: IBM 9406-170, V4R5, 9910-080
