Solution Type Technical Instruction Sure Solution 1017951.1 : Sun Fire[TM] Server (280,480,880 and 880z)Interpreting POST results from the "ESB Overall Status"
PreviouslyPublishedAs 229221 Description This document explains how to interpret the closing POST message on the Sun Fire[TM] systems. The following is the usual message seen from a POST without errors encountered: Power On Selftest Completed Pass/Fail Status = 0000.0000.0000.0000 ESB Overall Status = ffff.ffff.ffff.ffff Steps to Follow This document can be useful when only the final part of a POST output is available to be analyzed. The last thing that is shown is that the Power On Self Test has completed. The status of POST is returned in two areas:
The ESB Overall Status uses the following hex layout to define failures or successful passes: if a component has failed in POST, its bit is set to 0 (failed); otherwise, the bit is set to 1 (pass). Refer to Figure 1 for the ESB Overall Staus Bit Definition. Note: Bits are numbered from 63-0, with 0 being the LSB (Least Significant Bit, that is, the rightmost bit) The hex value f represents the binary value 1111. If CPU 2 goes bad, the binary value will become 1011. This represents the hex value b. The overall status value will become ffff.ffff.ffff.fffb Refer to Figure 2 for the Hex to Binary converions.
