MAXDATA PLATINUM Server Board
CAUTION
The system is off only when the AC power cord is disconnected.
System Management
MAXDATA integrates system management features into the hardware and provides additional
features through Intel
®
Server Management
software.
Baseboard Management Controller
MAXDATA 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 (SDR
s),
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).
Field Replaceable Units and Sensor Data Records
Field replaceable units (FRUs)
are major modules in the chassis that contain active electronic
circuitry. FRUs can store information-such as board serial number, part number, name, and
asset tag-that can be read using the System Setup Utility
. The BMC
stores FRU information
for the baseboard in a nonvolatile storage component on the board.
The BMC
uses Sensor Data Record
s (SDRs) to identify the sensors in the system for
monitoring. SDRs provide a list of the sensors, their characteristics, location, type, and
type-specific information, such as default threshold values, factors for converting a sensor
reading into the appropriate units (mV, rpm, degrees Celsius), and information on the types
of events that a sensor can generate. The BMC stores SDR information in a nonvolatile
storage component on the baseboard.
You can use the FRU/SDR Load Utility
to initialize or update the FRU and SDR information. You
should run the FRU/SDR Load Utility whenever you change the number of fans, processors,
or power supplies in the server.
System Event Log
The BMC
manages a system event log (SEL
)
, where it records significant or critical system
events. These events include temperatures and voltages out of range, fan failures, and other
sensor-related events. The BIOS, software, and other devices can also log events by sending
messages to the BMC. The SEL is stored in nonvolatile storage.
You can view the current contents of the SEL by using the System Setup Utility
.
