I have a Supermicro Redundant Power Supply with two units in it. I also have two UPS units, one for each of the Power Supplys. I was watching the LCD on the UPSs for the watt usage. The total watts equal about 400 Watts. This is where it gets strange. I observed the following, something that i have not seen on any of my 30 other Supermicro Redundant Power Supply setups.
It starts with...
UPS1 200 Watts UPS2 200 Watts.
Stays the same for 3 seconds and then changes with in a second to...
UPS1 0 Watts UPS2 400 Watts.
Stays the same for 3 seconds and then changes with in a second to...
UPS1 200 Watts UPS2 200 Watts.
Stays the same for 3 seconds and then changes with in a second to...
UPS1 400 Watts UPS2 0 Watts.
Stays the same for 3 seconds and then starts the cycle over again.
The wattage is sloshing back and forth 200 Watts at a time from one UPS to the other. I know it has been doing this for at least 6 hours now and i am not sure how if it was doing this before or not.
Does anyone have any ideas of what may be going on. Maybe some things i could try?
