Viewing power consumption status
CMC provides the actual input power consumption for the entire system.
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
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 with the attributes System Input Power cap,
Redundancy Policy, power budget details with the attributes System Input Max Power Capacity, Input Redundancy Reserve,
Power Available for Server Power-on, and chassis power supply with the power supply unit details. For more information, see the
CMC for Dell PowerEdge FX2/FX2s 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 Dell Chassis Management
Controller for PowerEdge FX2/FX2s 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. If
the PSU installed on a chassis fails owing to some reason, the overall power health status of the chassis is displayed as Non-Critical.
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.
The active CMC polls the health status from the standby CMC to determine if the chassis is redundant. When you disconnect the
network cable, a chassis failover is triggered after 30 seconds. And, the standby CMC is active. The network disruption causes the
originally active CMC to boot after about three minutes and becomes a standby CMC. The health monitoring task on the standby CMC
resumes after five minutes. Health changes, if any, on the standby are processed only after the standby is stable. The active CMC must
wait for eight-and-a-half minutes to determine if redundancy exists. Ensure that the redundancy state is healthy before initiating any
failover owing to the health changes.
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.
