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.
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
In the event of a PSU failure or removal, the power supplied to servers may be reduced. In extreme cases servers could be powered
off in an attempt to sustain operation. Configuring and maintaining Grid Redundancy avoids any impact to servers for a single PSU
failure.
Power supply and Redundancy policy changes in system event log
Changes in the power supply state and power redundancy policy are recorded as events. Events related to the power supply that
record entries in the system event log (SEL) are power supply insertion and removal, power supply input insertion and removal, and
power supply output assertion and de-assertion.
The following table lists the SEL entries that are related to power supply changes:
