RP8420 Cell Board has 1 VRM Fault --- A Show Stopper?

We've a big deployment ona recently purchased RP8420 with PA-8900 Cores (1100Mhz). As final checks before deciding to go ahead or not, I notice the following when I do a PS.

Everything in SL and FPL however checks out fine... Even EMS and DIAGS do not complain... Should I cancel/abort? And I can just drop this CELL fromthe config... ? This is a 32-core system and initially we only need ~ 20 CPUs...

i know there are 3 x 1.2V VRM in the rp8420 cell board, i.e. VRM 1, 2 and 3, but not sure if they are redundant though.
