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 37. SEL Events for Power Supply Changes
Power Supply Event

AC input received
AC input lost
DC output produced

110V operation acknowledged
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 AC Redundancy power policy or Power
Supply Redundancy power policy. The following table lists the SEL entries that are related to power redundancy policy
changes.

Configuring Power Budget and Redundancy

You can configure the power budget, redundancy, and dynamic power of the entire chassis (chassis, servers, I/O
modules, iKVM, CMC, and power supplies), which uses six power supply units (PSUs). The power management service
optimizes power consumption and re-allocates power to different modules based on the requirement.
Dynamic PSU Firmware Response
Engagement
Disabled Decrease power to low priority servers, if needed.
Enabled CMC alerts you of loss of AC Redundancy. PSUs in standby mode
(if any) are turned on to compensate for power budget lost from
the PSU failure or removal.
Enabled CMC alerts you of loss of Power Supply Redundancy. PSUs in
standby mode (if any) are turned on to compensate for power
budget lost from PSU failure or removal.
Enabled Decrease power to low priority servers, if needed.
