Intel® Server Board SE7320SP2 & Intel Server Board SE7525GP2 TPS Platform Management
Revision 2.0 124
Critical Condition
Any critical or non-recoverable threshold crossing associated with the following events:
• Temperature, voltage, or fan critical threshold crossing.
• Power subsystem failure. The BMC asserts this failure whenever it detects a power
control fault (e.g., the BMC detects that the system power is remaining on even though
the BMC has deasserted the signal to turn off power to the system). A hot-swap
backplane would use the Set Fault Indication command to indicate when one or more of
the drive fault status LEDs are asserted on the hot-swap backplane.
• The system is unable to power up due to incorrectly installed processor(s), or processor
incompatibility.
• Satellite controller sends a critical or non-recoverable state, via the Set Fault Indication
command to the BMC.
• “Critical Event Logging” errors, including: System Memory Uncorrectable ECC error and
Fatal/Uncorrectable Bus errors, such as PCI SERR and PERR.
Non-Critical Condition
• Temperature, voltage, or fan non-critical threshold crossing
• Chassis intrusion
• Satellite controller sends a non-critical state, via the Set Fault Indication command, to
the mBMC
• Set Fault Indication command from system BIOS. The BIOS may use the Set Fault
Indication command to indicate additional, non-critical status such as system memory or
CPU configuration changes.
Degraded Condition
• One or more processors are disabled by Fault Resilient Boot (FRB) or BIOS
• BIOS has disabled or mapped out some of the system memory
5.3.4.6 Chassis Intrusion Switch
Some platforms support chassis intrusion detection. On these platforms, the mBMC monitors
the state of the Chassis Intrusion signal and makes the status of the signal available via the Get
Chassis Status command and Physical Security sensor state. If enabled, a chassis intrusion
state change causes the mBMC to generate a Physical Security sensor event message with a
General Chassis Intrusion offset.
5.3.4.7 Front Panel Lockout
The management controller monitors a ‘Secure Mode’ signal from the keyboard controller on the
server board. When the Secure Mode signal is asserted, the management controller may lock
out the ability to power down or reset the system using the power or reset push buttons,
respectively. Secure Mode may also block the ability to initiate a sleep request using the Sleep
push-button.
