Alert
The mBMC maintains an Event Filter table with 30 entries that is used to select the actions to
perform. Also maintained is a fixed/read-only Alert Policy Table entry. No alert strings are
supported.
Note:
All Fault/Status LED and ID LED behaviors are driven off of PEF. PEF should not be
disabled and the manufacturing shipping configuration should not be modified or those
behaviors will be changed.
Each time the PEF module receives either an externally or internally generated event message,
it compares the event data against the entries in the event filter table. The mBMC scans all
entries in the table and determines a set of actions to be performed. If a combination of actions
is identified, such as power down, power cycle, and/or reset actions, the action are performed
according to PEF Action Priorities. Action priorities are outlined in the table below.
Note:
An action that has changed from delayed to non-delayed, or an action whose delay time
has been reduced has a higher priority. Each generated event is logged by SEL.
