You can identify the model and hardware configuration of a PA by referring
to the product code printed on labels on the heatsink and rear of the cover.
The meaning of each character in the product code is explained in the table
below.
Note
This explanation of PA product codes is not intended to suggest
that any combination of features is necessarily available in any one
