High Availability Software for the Intel® NetStructureTM ZT 4901 Technical Product Specification 27
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.
4.2.2 Isolation 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.
