Sensor Monitoring; Field Replaceable Unit (Fru) Inventory Device - Intel S2600CO series User Manual

Intel® Server Board S2600CO Family TPS
timer to indicate that it is using the timer for the FRB2 phase of the boot operation. After the
BIOS has identified and saved the BSP information, it sets the FRB2 timer use bit and loads the
watchdog timer with the new timeout internal.
If the watchdog timer expires while the watchdog use bit is set to FRB2, the BMC (if so
configured) logs a watchdog expiration event showing the FRB2 timeout in the event data bytes.
The BMC then hard resets the system, assuming the BIOS-selected reset as the watchdog
timeout action.
The BIOS is responsible for disabling the FRB2 timeout before initiating the option ROM scan
and before displaying a request for a boot password. If the processor fails and causes an FRB2
timeout, the BMC resets the system.
The BIOS gets the watchdog expiration status from the BMC. If the status shows an expired
FRB2 timer, the BIOS enters the failure in the system event log (SEL). In the OEM bytes entry
in the SEL, the last POST code generated during the previous boot attempt is written. FRB2
failure is not reflected in the processor status sensor value.
The FRB2 failure does not affect the front panel LEDs.

Sensor Monitoring

The BMC monitors system hardware and reports system health. Some of the sensors include
those for monitoring.
Component, board, and platform temperatures

Board and platform voltages

System fan presence and tach

Chassis intrusion

Front Panel NMI

Front Panel Power and System Reset Buttons

SMI timeout

Processor errors

The information gathered from physical sensors is translated into IPMI sensors as part of the
"IPMI Sensor Model". The BMC also reports various system state changes by maintaining
virtual sensors that are not specifically tied to physical hardware.

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 through all interfaces.
The BMC provides FRU device command access to its own FRU device and to the FRU
devices throughout the server. The FRU device ID mapping is defined in the Platform Specific
Information. The BMC controls the mapping of the FRU device ID to the physical device
Revision 1.4
