This document provides tables of the Non-Cacheable Address Space for Sun Fire[TM] 3800-6800 systems. The tables can be used for decoding AFAR and (for USIII Cu) AFAR_2 registers on Sun Fire 3800-6800, v1280, and Netra[TM] 1280 systems. Decoding the registers in case of a Domain failure won't necessarily have anything to do with the error, but in practice it often helps to determine a suspect FRU(s).

Caution:  This topic is quite complicated and it is recommended that customers needing to investigate this type of fault do so with caution.  It's advisable to contact Support Services and open a Service Request for this to be resolved.

Refer to Document 1004877.1 for a cheatsheet that provides a breakdown of the address spaces listed in the tables below. The cheatsheet can be used to short circuit the manual decoding of address spaces with simple look-up tables for non-cacheable addresses.
