232 Power Management
Events related to changes in the power redundancy policy that record entries
in the SEL are redundancy loss, redundancy degradation and redundancy
regain for the modular enclosure that is configured for either an AC
Redundancy power policy or Power Supply Redundancy power policy. A
modular enclosure that is configured in the Non Redundant power policy will
record a SEL entry for insufficient resources, Non Redundant power policy is
recorded when the functional power supply count drops below the enclosure
minimum of three power supplies. Similarly, when the functional power
supply count is restored, a SEL entry for sufficient resources, Non Redundant
power policy, is recorded. Table 8-5 lists the SEL entries that are related to
power redundancy policy changes.
