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.
Table 41. 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
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.
