Power Supply and Redundancy Policy Changes in System Event Log

Changes in the power supply state and power redundancy policy are recorded as events. Events related to the power supply that record entries in the system event log (SEL) are power supply insertion and removal, power supply input insertion and removal, and power supply output assertion and de-assertion.

The following table lists the SEL entries that are related to power supply changes:

Table 31. SEL Events for Power Supply Changes

Power Supply Event	System Event Log (SEL) Entry
Insertion	Power supply is present.
Removal	Power supply is absent.
AC input received	The power input for power supply has been restored.
AC input lost	The power input for power supply is lost.
DC output produced	Power supply is operating normally.
DC output lost	Power supply failed.

Events related to changes in the power redundancy status that record entries in the SEL are redundancy loss and redundancy regain for the modular enclosure that is configured for either an Grid Redundancy power policy or Power Supply Redundancy power policy. The following table lists the SEL entries that are related to power redundancy policy changes.

Power Policy Event	System Event Log (SEL) Entry
Redundancy lost	Power supply redundancy is lost.
Redundancy regained	The power supplies are redundant.

Configuring Power Budget and Redundancy

You can configure the power budget, redundancy, and dynamic power of the entire chassis (chassis, servers, I/O module, KVM, CMC, and power supplies), which uses four power supply units (PSUs). The power management service optimizes power consumption and reallocates power to different modules on the basis of requirement.

You can configure the following:

•System Input Power Cap

•Redundancy Policy

•Enable Dynamic Power Supply Engagement

•Disable Chassis Power Button

•Max Power Conservation Mode

•Remote Power Logging

•Remote Power Logging Interval

•Server Based Power Management
