Secure Mode And Front Panel Lock-Out Operation - Intel S7000FC4UR Technical Product Specification

BMC Functional Specifications
The BMC detects chassis intrusion and logs a SEL event when the system is in the on, sleep, or
standby state. Chassis intrusion is not detected when the system in an AC power-off state.
22.6.4.2 Reset Button
An assertion of the Front Panel Reset signal to the BMC causes the system to start the reset
and reboot process, as long as the BMC has not locked-out this input. This assertion is
immediate and without the cooperation of software or the operating system.
22.6.4.3 Diagnostic Interrupt (Front Panel NMI)
A diagnostic interrupt is a non-maskable interrupt or signal for generating diagnostic traces and
core dumps from the operating system. The diagnostic interrupt button is connected to the BMC
through a front panel connector. Once an NMI has been generated by the BMC, the BMC does
not generate another until the system has been reset or powered down.
22.6.4.4 Chassis Identify
The front panel chassis identify button toggles the state of the chassis ID LED. If the LED is off,
then pushing the button lights the LED. It remains lit until the button is pushed again or until a
Chassis Identify or Chassis Identify LED command is received that changes the state of the
LED.

Secure Mode and Front Panel Lock-out Operation

Secure mode protects the front panel buttons against unauthorized use. Secure mode is
enabled and controlled by the Set Secure Mode Options command.
If a protected front panel button is pressed while the system is in secure mode, a secure mode
violation event is generated. Secure Mode Violation Attempt offset (00h) of the BMC's Security
Violation Attempt sensor is asserted.
Secure mode is cleared whenever AC power is applied, when a system reset occurs, or when a
BMC reset occurs. The secure mode state includes the bits that specify which actions are to be
taken when secure mode is active the Force Secure Mode On bit.
The Set Secure Mode Options command protects front panel buttons regardless of the secure
mode state. This protection includes blocking the buttons and generating secure mode violation
events if one of the buttons is pressed when in secure mode state. The front panel power and
reset buttons must be protected as a unit. They cannot be individually locked.
The set of buttons that is protected when secure mode is active varies, depending on the
system ACPI power state.
