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 congured 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.
Table 49. SEL Events for Power Redundancy Policy Changes
Power Policy Event System Event Log (SEL) Entry
Redundancy lost Redundancy lost was asserted
Redundancy regained Redundancy lost was de-asserted
Conguring power budget and redundancy
You can congure 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 dierent modules based on the requirement.
You can congure the following:
• System Input Power Cap
• Redundancy Policy
• Extended Power Performance
• Server Performance Over Power Redundancy
• Dynamic Power Supply Engagement
• Disable Chassis Power Button
• Allow 110 VAC Operation
• Max Power Conservation Mode
• Remote Power Logging
• Remote Power Logging Interval
• Server Based Power Management
• Disable AC Power Recovery
