c3000 Power problems

[chuckk281]

Steve was having c3000 power issues and needed some guidance:

***********************

The two blades are now sorted after replacing the system boards (tried reseating but no good).

iLO communication is also sorted. But I still have the reporting issue with the power, even after reseating the OA and OA tray and upgrading to 3.11.

As you can see, none of the power supplies are reporting values out of the normal. One thing I have noticed is that supply 1 & 4 are the newer 500172-B21 PSU whereas 2, 3, 5 & 6 are the older 437572-B21. Are the two allowed to coexist? At the moment this appears to be just a reporting issue – all blades & VC’s working fine – can it be safely ignored?

Hello Steve,

The two power supplies cannot coexist.  All the power supplies must be the same SKU.  I believe that is the problem you are experiencing.

We have seen this question many times before and since the power supply characteristics are different when you go to the newer Platinum supplies, you need to change them all in an enclosure to have Power Capping and Thermal Logic work correctly. And Steve seems to have seen what else can happen.
