Identifying CPU/Memory Modules

Since each CPU/memory module has its own set of DIMMs, you need to determine
the CPU/memory module in which a faulty DIMM resides. This information is
given in the POST error message:
1>H/W under test = CPU3 B0/D1 J0602 side 1 (Bank 1), CPU Module C3
In this example, the cited module is
The processors are numbered according to the slot in which they are installed, and
these slots are numbered 0 to 3, left to right, as you look down on the Sun Fire V440
server's chassis from the front (see
FIGURE 2-5
For example, if a Sun Fire V440 server has only two CPU/memory modules
installed, and if those are located in the left most and right most slots, then the
firmware will refer to the two system processors as CPU 0 and CPU 3.
The failed DIMM called out by the previous POST error message, then, resides in the
right most CPU/memory module (C3), and is labeled B0/D1 on that module's
circuit board.
