Fru Information - Intel SE7520AF2 Technical Product Specification

Intel® Server Board SE7520AF2 TPS
− Temperature, voltage, or fan critical threshold crossing
− Power subsystem failure. The management controller asserts this failure whenever it
detects a power control fault (e.g., detects that the system power is remaining on even
though the management controller has de-asserted the signal to turn off power to the
system).
− "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
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
6.3.4.6 Chassis Intrusion Switch
The Intel® SE7520AF2 server platform supports chassis intrusion detection. 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.
6.3.4.7 Front Panel Lockout
The management controller monitors a 'Secure Mode' signal from the keyboard controller on the
baseboard. When the Secure Mode signal is asserted, the management controller locks out the
ability to power down or reset the system using the power or reset push buttons, respectively.
Secure Mode does not block the ability to initiate a sleep request using the Sleep push-button.
The management controller generates a 'Secure Mode Violation Attempt' event message if an
attempt it made to power-down, or reset the system using the push buttons while Secure Mode
is active.
The set of buttons protected when Secure Mode is active varies depending on the system ACPI
power state and whether the Sahalee BMC or the mBMC is in control as shown in table Table
68. Differences are highlighted.
Note: The mBMC will prevent the system from powering up via button press when either secure
mode or the front panel lockout I/O signal is asserted.

FRU Information

The platform management architecture supports providing Field Replaceable Unit (FRU)
information for the baseboard and major replaceable modules in the chassis. 'Major Module' is
defined as any circuit board in the system containing active electronic circuitry.
