1. Theory of Operations
1.1 Overview
This chapter introduces the Everest (POWERpath-2) board set and shows how those
boards communicate over the various system and board buses. Figure 1-1 is a high-level
functional block diagram of the Everest board set installed in a typical system. Figure 1-2
illustrates the IO4 board architecture in greater detail. As the individual diagnostic tools
are discussed, similar diagrams highlight the areas affected by that tool (where
appropriate).
