5 System Management Intel integrates system management features into the hardware and provides additional features through Intel Server Management software. This section describes the integrated hardware features, Intel Server Management software, and the System Setup Utility and FRU/SDR Load Utility used to configure the hardware features. Integrated Hardware System Management Figure 2 is a simplified diagram of the system management features integrated into the server.

Integrated System Management Baseboard Management Controller Intel server boards incorporate 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. • Provides the main front panel control functions (power on/off, reset, and so on). 47
