Appendix B: System management164Integrated hardware systemmanagementThe figure below is a simplified diagram of the system managementfeatures integrated into the server.Baseboard management controllerThe Altos G900 system incorporates a baseboard managementcontroller (BMC), which is a dedicated microcontroller for systemmanagement activities. The BMC performs the following functions:• Monitors system components and sensors, including processors,memory, fans, power supplies, temperature sensors, and chassisintrusion sensors.• Manages nonvolatile storage for the system event log (SEL), sensordata records (SDRs), and baseboard field-replaceable unit (FRU)inventory.• Interfaces with the emergency management port (EMP) and LAN1port to send alerts and interact with remote management systems.Figure 71 - Integrated system management
