System Management
Intel integrates system management features into the hardware and provides additional features
through Intel
®
Server Management (ISM) software version 5.5. A brief description of the features
is provided below. For instructions on using the features described, refer to the Configuration
Software and Utilities chapter, beginning on page 77.
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).
