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.
