The System management software (SMS) is running on a host system that communicates via<br />
the Remote management control protocol (RMCP) over Ethernet with the <strong>MCH</strong>. The <strong>MCH</strong><br />
itself implements base management controller (BMC) functionality and communicates via<br />
IPMI messages over I2C with hardware modules (e.g. Cooling Units, Power Modules, AMC<br />
cards) that run hardware module specific software.<br />
The next figure gives an example for a software implementation that uses the graphical<br />
N.A.T. JAVA application (see Fehler! Verweisquelle konnte nicht gefunden werden.) and<br />
