Integrated hardware system management
The figure below is a simplified diagram of the system management
features integrated into the server.

Baseboard management controller

The Altos G900 system incorporates a baseboard management
controller (BMC), which is a dedicated microcontroller for system
management activities. The BMC performs the following functions:
• Monitors system components and sensors, including processors,
memory, fans, power supplies, temperature sensors, and chassis
intrusion sensors.
• Manages nonvolatile storage for the system event log (SEL), sensor
data records (SDRs), and baseboard field-replaceable unit (FRU)
inventory.
• Interfaces with the emergency management port (EMP) and LAN1
port to send alerts and interact with remote management systems.
