Hi,   I don't think it's possible for any settings for the server to accept mixed input voltages. Page 16: [URL] under second caution clause.     
Hi guys I'm having trouble with two redundants PSUs on a R820 server. When both PSUs are connected, a green light is blinking on PSU2. When a single PSU is connected (regardless of slot), the green light does not flash and no alarm on the IDRAC is detected. Accessing IDRAC the psu alarms configuration error. Also tried to access the lifecycle controller but found no firmware update for any of the PSUs. Does anyone have any idea what might be going on? [IMAGE] Thanks
