Hi

Had the same problem some weeks ago, with a 7609-S and PWR-4000-DC

I found that all 3 input wires needs to be connected, anf with only two connected lower power will be reported.

Guess the same issue applies for your configuration

Hello Ravi,

Try below two command and see if both output watts are close. If not it is not alarming condition

If close than you can chane power redundancy mode to combined but only if there is log message of low power input

#sh power used
system power used =      1794.66 Watts (42.73 Amps @ 42V)

#sh power available
system power available = 3976.98 Watts (94.69 Amps @ 42V)

You should also consider input given by jon because he is having some practical experience

Regards

Check notes below this paragraph:

Power may run in 2 modes: 2700W or 4000W

Connecting 2 DC connections provides 2700W

Connecting 3 DC connections provides 4000W

Selection is auto-sense
