System Management

•Upper/Lower critical threshold

•Upper/Lower non-recoverable threshold

Each range can be set independently for each sensor and the ranges can overlap. This area of configuration is used only to trigger events. These events appear in the System Event Log. Platform Event Filtering (PEF) determines the actions that occur as a result of these events. Only the Upper/Lower non-recoverable threshold is typically configured using the PEF to cause a hardware-initiated takeover to occur.

4.2.2Isolation Strategies

The BMC handles the following event actions in its PEF Table:

•Alert

•Power Off

•Reset

•Power Cycle

•Diagnostic Interrupt (NMI)

These options can be set independently for each event.

Support for a Handover action allows the takeover / handover process to occur from the BMC. This action triggers the CompactPCI Interface Controller (CIC) to initiate the handover sequence. A virtual RH channel facilitates this switchover request.
