Hello Team
WE just had recently installed 6807-XL with 4 PSMs
it happens that when am checking the power redundancy of the system and 2 PSMs are down the other 2 PSMs behaves differently
sometimes in a (1+1) mode and some other times in (2+0) mode, as shown below
#sh power
system power redundancy mode = redundant
system power redundancy operationally = combined(2+0)
system power total = 5699.72 Watts (109.61 Amps @ 52V)
system power used = 3038.36 Watts (58.43 Amps @ 52V)
system power available = 2661.36 Watts (51.18 Amps @ 52V)
Power-Capacity PS-Fan Output Oper
PS Type Watts A @52V Status Status State

3 C6800-XL-3KW-AC 1300.00 25.00 - - off
4 C6800-XL-3KW-AC 2999.88 57.69 OK OK on

My question is, How the system assigns in the (3+1) mode the redundant PSM ? And, when 2 PSMs are down, how to make sure that the other 2 PSMs will always be (2+0) instead of (1+1) ?
thanks
