02 is Poughkeepsie. 51 was Montpellier. 83 was Dublin, 84 was Singapore. I just 
saw a 8562-T02 with 78 as plant number – which I’m guessing is Brasil. (The 
customer is near Europe / Asia border so that surprised me.)

Subject: [EXTERNAL] Plant 02
As we know there is a field called plant number.
It is used in FC/FICON and in Coupling Facility definition, and it is a
part of machine serial displayed in HMC.
Example:
000 02 00 12345
(spaces added for visibility)

I noticed some z16 machine in Europe has plant 02. Previous generation
had 84, which was Singapore, AFAIK.
I was told the 01 is POK (Poughkeepsie).

So, what is 02?
