Hi Paul, I am using a X460, which gives me an output like the one below:
Switch : XXXXXX-XX-XX XXXXX-XXXXX Rev 2.0 BootROM: 2.0.1.7 IMG: 15.6.1.4
SS-B-1 : XXXXXX-00-X1 XXXXG-XXXXXX Rev 1.0
PSU-1 : EDPS-XXXAB A-S9 XXXXXX-00-03 XXXXE-XXXXX
PSU-2 :
You're on a X250, running version 12. I am not sure you'd see a output similar to what I have probably because the X250 doesn't have a field replaceable (modular) PSU, but again, I am speculating on this one. Will wait and hear back from the team!
