Intel® Server Board S2600GZ/GL TPS Platform Management Functional Overview  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. See Appendix B - Integrated BMC Sensor Tables for additional sensor information. 6.7 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 6.8 System Event Log (SEL) The BMC implements the system event log as specified in the Intelligent Platform Management Interface Specification, Version 2.0. The SEL is accessible regardless of the system power state through the BMC's in-band and out-of-band interfaces. The BMC allocates 65,502 bytes (approx 64 KB) of non-volatile storage space to store system events. The SEL timestamps may not be in order. Up to 3,639 SEL records can be stored at a time. Any command that results in an overflow of the SEL beyond the allocated space is rejected with an "Out of Space" IPMI completion code (C4h). Events logged to the SEL can be viewed using Intel's SELVIEW utility, Embedded Web Server, and Active System Console. 6.9 System Fan Management The BMC controls and monitors the system fans. Each fan is associated with a fan speed sensor that detects fan failure and may also be associated with a fan presence sensor for hotswap support. For redundant fan configurations, the fan failure and presence status determines the fan redundancy sensor state. The system fans are divided into fan domains, each of which has a separate fan speed control signal and a separate configurable fan control policy. A fan domain can have a set of temperature and fan sensors associated with it. These are used to determine the current fan domain state. Revision 1.1 57 Intel order number G24881-004
