I've got a D2700 SAS with the standard dual 460W power supplies, part # 499250-101. When the UPS that it's connected to switches over to battery, this unit shuts down. No other associated equipment does this. Even just plugged into the UPS by itself still behaves this way. I can't tell if the PSs are not designed to handle this situation or they are defective.
Is there a way to test or any documentation for these PSs that would tell me what the power response time should be, and if it has any issues with a stepped-wave UPS? Alternately, any replacement supplies that are compatible with this UPS situation and the D2700.
