Redundancy Status and Overall Power Health
The redundancy status is a factor in determining the overall power health.
When the power redundancy policy is set, for example, to AC Redundancy
and the redundancy status indicates that the system is operating with
redundancy, the overall power health is typically OK. However, if the
conditions for operating with AC redundancy cannot be met, the redundancy
status is No, and the overall power health is Critical. This is because the
system is not able to operate in accordance with the configured redundancy
policy.
NOTE: CMC does not perform a pre-check of these conditions when you change
the redundancy policy to or from AC redundancy. So, configuring the redundancy
policy may immediately result in redundancy lost or a regained condition.
Configuring and Managing Power
You can use the Web-based and RACADM interfaces to manage and
configure power controls on CMC. Specifically, you can:
• View power allocations, consumption, and status for the chassis,
servers, and PSUs.
• Configure System Input Power Cap and Redundancy Policy for the chassis.
• Execute power control operations (power-on, power-off, system reset,
power-cycle) for the chassis.
Viewing the Health Status of the PSUs
The Power Supply Status page displays the status and readings of the PSUs
associated with the chassis.
Using the Web Interface
The PSU health status can be viewed in two ways: from the Chassis Graphics
section on the Chassis Status page or the Power Supply Status page.
The Chassis Graphics page provides a graphical overview of all PSUs
installed in the chassis.
