Intel® Server System S7000FC4UR TPS BMC Functional Specifications
Revision 1.0
265
allocates 65,536 bytes (64 KB) of non-volatile storage space for the SDR. See Table 38 for SDR
command support.
22.10.1 SDR Repository Erasure
SDR repository erasure is a background process. After initiating erasure with the Clear SDR
Repository command, additional Clear SDR Repository commands must be executed to get
erasure status and determine when the SDR repository erasure is done. This may take several
seconds. The SDR repository cannot be accessed or modified until the erasure is done.
22.11 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 via all interfaces.
The BMC provides only low-level access to the FRU inventory area storage. It does not validate
or interpret the data that are written. This includes the common header area. Applications
cannot relocate or resize any FRU inventory areas.
Note: Fields in the internal use area are not for OEM use. Intel reserves the right to relocate
and redefine these fields without prior notification. Definition of this area is part of the software
design. The format in the internal use area may vary with different BMC firmware revisions.
22.12 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 (Example: On each power-up attempt), but are
not sounded continuously. Supported codes are in Table 101. Each digit in the code is
represented by a sequence of beeps whose count is equal to the digit.
Table 101. BMC Beep Codes
Code Reason for Beep Associated Sensors Supported
1-5-2-1 CPU: Empty slot / population error. CPU missing error Yes
1-5-4-2 Power fault: DC power unexpectedly lost (power
good dropout)
Power unit – power unit
failure offset
Yes
1-5-4-4 Power control fault (Power good assertion
timeout)
Power unit – soft power
control failure offset
Yes
22.13 NMI
On IA-32 platforms, the BMC has monitoring and signal generation functionality in regards to
the NMI (non-maskable interrupt) signal. When the BMC generates a diagnostic interrupt, the
NMI signal is pulsed. A front panel diagnostic interrupt sensor is used to log SEL events for
assertion of the diagnostic interrupt.
