Switch & Management Module
The Switch & Management Module is designed to control the system unit and monitor the environment.
Figure 28 shows the block diagram of the module. This module and other system components are
connected through I2C or other busses.

Figure 28. Switch & Management Module components
The Switch & Management Module contains the service processor (SVP) which controls the system
and monitors the environment. A SVP is connected to the server blades or another SVP on the other
Switch & Management Module (if mounting two Switch & Management Modules) through the
backplane interfaced by 100M/10M Ethernet. Further, an SVP is connected to the server blades,
another SVP or the I/O modules through the backplane by an I2C interface. The SVP performs tasks
including system control, monitoring, and notice of a fault. The SVP is equipped with a console
interface, which provides a user interface for maintaining and managing the system. Table 12 defines
the components of the Switch & Management Module.
Two Switch & Management Modules can be installed on one chassis. In this case, the main SVP
normally performs the SVP function. Health checking works between the main and sub-SVP as they
monitor each other. If the main SVP fails, the sub-SVP takes over operation.
The Switch & Management Module houses the gigabit Ethernet switch, to which the gigabit Ethernet
port of each server blade is connected over the backplane. When two Switch & Management Modules
are installed, each switch operates independently.
