1 Description18System ManagementASMe integrates system management features into the hardware andprovides additional features through ASMe Server Managementsoftware. This section describes the integrated hardware features, AcerAdvance Server Management software, and the System Setup Utilityand FRU/SDR Load Utility used to configure the hardware features.Baseboard Management ControllerAcer server boards incorporate a baseboard management controller(BMC), which is a dedicated microcontroller for system managementactivities. 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.• Provides the main front panel control functions (power on/off,reset, and so on).Field Replaceable Units and Sensor Data RecordsField replaceable units (FRUs) are major modules in the chassis thatcontain active electronic circuitry. FRUs can store information-such asboard serial number, part number, name, and asset tag-that can beread using the System Setup Utility (see “Viewing FRU Information” onpage 64). The BMC stores FRU information for the baseboard in anonvolatile storage component on the board.The BMC uses Sensor Data Records (SDRs) to identify the sensors in thesystem for monitoring. SDRs provide a list of the sensors, theircharacteristics, location, type, and type-specific information, such asdefault threshold values, factors for converting a sensor reading intothe appropriate units (mV, rpm, degrees Celsius), and information onthe types of events that a sensor can generate. The BMC stores SDRinformation in a nonvolatile storage component on the baseboard.
