Viewing Power Consumption Status Using RACADM
To view power consumption status using RACADM:
Open a serial/Telnet/SSH text console to CMC, log in, and type:
racadm getpminfo
Viewing Power Budget Status Using CMC Web Interface
To view power budget status using CMC Web interface, in the left pane go to Chassis Overview and click
Power → Budget Status. The Power Budget Status page displays the system power policy configuration,
power budget details, budget allocated for server modules, and chassis power supply details. For more
information, see the Online Help.
Viewing Power Budget Status Using RACADM
Open a serial/Telnet/SSH text console to CMC, log in, and type:
racadm getpbinfo
For more information about getpbinfo, including output details, see the getpbinfo command section in
the Chassis Management Controller for PowerEdge VRTX RACADM Command Line Reference Guide.
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 Grid 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 Grid 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 Grid redundancy. So, configuring the redundancy policy may immediately result in
redundancy lost or a regained condition.
Power Management After PSU Failure
When an insufficient-power event occurs, such as a PSU failure, CMC reduces power supply to the
servers . After reducing the power, CMC reevaluates the power needs of the chassis. If power
requirements are still not met, CMC turns off the lower priority servers. However, this is done on the basis
of power redundancy policy that you set on your CMC. A redundant server can tolerate the loss of power
without impacting the performance of the servers.
Power for higher priority servers is restored incrementally, while power needs remain within the power
budget. To set the redundancy policy, see Configuring Power Budget and Redundancy.
Power Management After Removing PSU
CMC may begin conserving power when you remove a PSU or a PSU AC cord. CMC decreases power to
the lower priority servers until power allocation is supported by the remaining PSUs in the chassis. If you
