Viewing Power Consumption Status Using CMC Web
Interface
In the left pane, click Chassis Overview > Power > Power Monitoring. The Power Monitoring page displays the power health, system
power status, real-time power statistics, and real-time energy statistics. For more information, see the Online Help.
NOTE: You can also view the power redundancy status under Power Supplies.
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
AC Power Recovery
If the AC power supply of a system is disrupted owing to power outage, power cables pulled from the power supply units (PSUs), or
power distribution unit (PDU) outage, the chassis is restored to the previous power state before the AC power loss. In case, the blade
servers are not configured to automatic power-up, you may have to power them on manually.
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.
