If it is enabled, Secure Mode can be controlled via the
Secure Mode KB
signal from the
keyboard controller. When Secure Mode is active, pressing a protected front panel switch
generates a Secure Mode Violation event. Specifically, this generates an assertion of the
Secure Mode Violation Attempt
offset of the mBMC’s
Platform Security Violation Attempt
sensor.
The Secure Mode state is cleared whenever AC power or system power is applied, when a
system reset occurs, or when a mBMC reset occurs. The Secure Mode state includes the bits
that specify the actions that are to be taken when Secure Mode is active, as well as the
Force
Secure Mode On
bit.
The
Set Secure Mode Options
command allows specific front panel switches to be protected
irrespective of Secure Mode state. See the command definition in the IPMI v1.5 specification for
details.
The NMI switch can be locked using the
Set Secure Mode Options
command but is never
protected by Secure Mode. This allows a system to be recovered from a hung state when
Secure Mode is active
5.3.6 FRU
Information
The platform management architecture supports providing FRU (field replaceable unit)
information for the server board and major replaceable modules in the chassis. ‘Major Module’
is defined as any circuit board in the system containing active electronic circuitry.
FRU information includes board serial number, part number, name, asset tag, and other
information. FRUs that contain a management controller use the controller to provide access to
the FRU information. FRUs that lack a management controller can make their FRU information
available via a SEEPROM directly connected to the IPMB or a private I
2
C bus. This allows the
system integrator to provide a chassis FRU device without having to implement a management
controller. This information can be accessed via IPMI FRU commands or using Master Write-
Read commands.
The mBMC implements the interface for logical FRU inventory devices as specified in the
Intelligent Platform Management Interface Specification, Version 1.5.
This functionality provides
commands used for accessing and managing the FRU inventory information associated with the
mBMC (FRU ID 0)
.
These commands can be delivered via all interfaces.
5.3.6.1
mBMC FRU Inventory Area Format
The mBMC FRU inventory area format follows the Platform Management FRU Information
Storage Definition. Refer to
Platform Management FRU Information Storage Definition, Version
1.0
for details.
The mBMC 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.
The server board’s FRU information is kept in the mBMC internal flash memory.
