3-36 SPARC Enterprise T1000 Server Service Manual • April 2007
3.4.5.1 Correctable Errors for Single DIMMs
If POST faults a single DIMM (CODE EXAMPLE 3-1) that was not part of a hardware
upgrade or repair, it is likely that POST encountered a correctable error that can be
handled by PSH.
In this case, reenable the DIMM and run POST in minimum mode as follows:
1. Reenable the DIMM.
2. Return POST to minimum mode.
3. Reset the system so that POST runs.
There are several ways to initiate a reset. The following example uses the
powercycle command. For other methods, refer to the SPARC Enterprise T1000
Server Administration Guide.
4. Replace the DIMM if POST continues to fault the device in minimum mode.
