   SPARC Enterprise M3000 platform:

      The JSC chip replaces both the SC chip and the MAC chip.

      The type of fault can be determined from the "Affects:" FMRI in the fmdump output.
      The types of faults that can be detected are:

         -Common logic internal to the JSC chip;
         -Part of the JSC chip that interfaces to an IO channel;
         -Part of the JSC chip that interfaces to a CPU chip;

         Faults that are common logic internal to the JSC chip:

            Platform becomes unbootable.

         Faults that are part of the JSC chip that interfaces to an IO channel:

            Domain using the IO Channel is reset.
            IO Channel will be deconfigured after the domain is reset.
          Platform becomes unbootable.

IO Channel 0 provides access to all internal I/O and PCI-Express slots 0, 1, 2, and 3.

           All IO on the platform is deconfigured and the platform becomes unbootable.

         Faults that are on part of the JSC chip that interfaces to a CPU chip:

            Domain using the CPU chip is reset.
            CPU chip will be deconfigured after the domain is reset.

   SPARC Enterprise M4000 platform:

      The type of fault can be determined from the "Affects:" FMRI in the fmdump output.
      The types of faults that can be detected are:

         -Common logic internal to the SC chip;
         -Part of the SC chip that interfaces to an IO channel;
         -Part of the SC chip that interfaces to a CPU chip;
         -Part of the SC chip that interfaces to a MAC chip;
         -Part of the SC chip that interfaces to a specific XSB.

         Faults that are common logic internal to the SC chip:

            Platform becomes unbootable.

         Faults that are part of the SC chip that interfaces to an IO channel:

            Domain using the IO Channel is reset.
            IO Channel will be deconfigured after the domain is reset.

               Availability of I/O devices depends on which IO Channel was deconfigured.

                  IO Channel 0 provides access to PCI-X slot 0, PCI-Express slots 1 and 2,
                  and all the internal I/O.

                  IO Channel 1 provides access to PCI-Express slots 3 and 4.

         Faults that are on part of the SC chip that interfaces to a CPU chip:

            Domain using the CPU chip is reset.
            CPU chip will be deconfigured after the domain is reset.

         Faults that are on part of the SC chip that interfaces to a MAC chip:

            Domain using the MAC chip is reset.
            8 DIMMs associated with this MAC will be deconfigured after the domain is reset.

         Faults that are part of the SC chip that interfaces to a specific XSB:

            Domain using the XSB is reset.
            XSB will be deconfigured after the domain is reset.

         -Part of the SC chip that interfaces to a MAC chip;
         -Part of the SC chip that interfaces to a specific XSB.

         Faults that are common logic internal to the SC chip:

            All domains are reset.

            One-half of the Motherboard with the faulty SC chip will be deconfigured,
            along with its associated I/O, after the domains are reset.

         Faults that are part of the SC chip that interfaces to an IO channel:

            Domain using the IO Channel is reset.
            IO Channel will be deconfigured after the domain is reset.

               Availability of I/O devices depends on which IO Channel was deconfigured.

                  IO Channel 0 provides access to PCI-X slot 0, PCI-Express slots 1 and 2,
                  and all the internal I/O.

                     IOU#0: Internal I/O includes the DVD drive, the DAT drive, HDD#0 and HDD#1.
                     IOU#1: Internal I/O includes HDD#2 and HDD#3.

                  IO Channel 1 provides access to PCI-Express slots 3 and 4.

            Domain using the CPU chip is reset.
            CPU chip will be deconfigured after the domain is reset.

         Faults that are on part of the SC chip that interfaces to a MAC chip:

            Domain using the MAC chip is reset.
            8 DIMMs associated with this MAC will be deconfigured after the domain is reset.

         Faults that are on part of the SC chip that interfaces to a specific XSB:

            Domain using the XSB is reset.
            XSB will be deconfigured after the domain is reset.

   SPARC Enterprise M8000/M9000 platforms:

      The type of fault can be determined from the "Affects:" FMRI in the fmdump output.
      The types of faults that can be detected are:

         -Common logic internal to the SC chip;
         -Part of the SC chip that interfaces to an IO channel;
         -Part of the SC chip that interfaces to a CPU chip;
         -Part of the SC chip that interfaces to a MAC chip;
         -Part of the SC chip that interfaces to a specific XSB.

         Faults that are common logic internal to the SC chip:

            CMU and all its associated I/O will be deconfigured after the domains are reset.

         Faults that are part of the SC chip that interfaces to an IO channel:

            Domain using the IO Channel is reset.
            IO Channel will be deconfigured after the domain is reset.

               Availability of I/O devices depends on which IO Channel was deconfigured.

                  IO Channel 0 on IOC chip 0 provides access to PCI-Express slots 0,1 on this IOU.

                  IO Channel 1 on IOC chip 0 provides access to PCI-Express slots 2,3 on this IOU.

                  IO Channel 0 on IOC chip 1 provides access to PCI-Express slots 4,5 on this IOU.

                  IO Channel 1 on IOC chip 1 provides access to PCI-Express slots 6,7 on this IOU.

         Faults that are on part of the SC chip that interfaces to a CPU chip:

            Domain using the CPU chip is reset.
            CPU chip will be deconfigured after the domain is reset.

         Faults that are on part of the SC chip that interfaces to a MAC chip:

            Domains using the MAC chip are reset.
            16 DIMMs associated with this MAC will be deconfigured after the domains are reset.


         Faults that are on part of the SC chip that interfaces to a specific XSB:

            Domain using the XSB is reset.
            XSB (CPU, Memory, and I/O) for the CMU in question will be deconfigured
            after the domain is reset.

The recommended service action for this event is to schedule the replacement of the affected FRU.
