Hi, I'm Shin from IBM Japan.
When we have 4 power supplies in C480M5 servers, Spec sheet tells us that we can select the power redundancy mode either as 2+2 or 3+1. If we choose 2+2, which is the power supply combination, (PS1, PS2) and (PS3, PS4), or (PS1, PS3) and (PS2, PS4)?

The recommendation is to connect PSU-1 and -2 to one feed and PSU-3 and -4 to another in the case of N+N. I am working on getting this documented externally in the spec sheet or install guide.
