Console Serial Bus Subsystem, CSB Block Diagram | Compaq GS320

8.1Console Serial Bus Subsystem

The console serial bus (CSB) links microprocessors throughout the system, forming a monitoring and control subsystem managed by the system control manager (SCM). The SCM microprocessor is located on the standard I/O module in the master PCI box. Figure 8–1 shows a block diagram of the CSB, the microprocessors (or “managers”), and the SCM. Also shown is a redundant SCM available as a standby console.
