4.8
Sensor Data Record (SDR) Repository
The BMC implements the sensor data record (SDR) repository as specified in the Intelligent
Platform Management Interface Specification, Version 2.0. The SDR is accessible through the
BMC’s in-band and out-of-band interfaces, regardless of the system power state. The BMC
allocates 65,519 bytes of non-volatile storage space for the SDR.
4.9
Field Replaceable Unit (FRU) Inventory Device
The BMC implements the interface for logical FRU inventory devices as specified in the
Intelligent Platform Management Interface Specification, Version 2.0. This functionality provides
commands used for accessing and managing the FRU inventory information. These commands
can be delivered through all interfaces.
The BMC provides FRU device command access to its own FRU device and to the FRU
devices throughout the server. The FRU device ID mapping is defined in the Platform Specific
Information. The BMC controls the mapping of the FRU device ID to the physical device.
4.10
Diagnostics and Beep Code Generation
The BMC may generate beep codes upon detection of failure conditions. Beep codes are
sounded each time the problem is discovered (for example, on each power-up attempt), but are
not sounded continuously. Common supported codes are listed in Table 19.
Additional platform-specific beep codes can be found in the appropriate Platform Specific
Information. Each digit in the code is represented by a sequence of beeps whose count is equal
to the digit.

PSU status
Yes
4.11
Diagnostics Interrupt (NMI)
The BMC generates an NMI pulse under certain conditions. The BMC-generated NMI pulse
duration is at least 30ms. Once an NMI has been generated by the BMC, the BMC does not
generate another NMI until the system has been reset or powered down.
