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 congured 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, conguring 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 o in
an attempt to sustain operation. Conguring 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:
Table 27. SEL events for power supply changes
Power Supply Event System Event Log (SEL) Entry
Insertion Power supply is present.
Removal Power supply is absent.
AC input received The power input for power supply has been restored.
AC input lost The power input for power supply is lost.
DC output produced Power supply is operating normally.
DC output lost Power supply failed.
Events related to changes in the power redundancy status that record entries in the SEL are redundancy loss and redundancy regain for
the enclosure that is congured for the Grid Redundancy power policy or Redundancy Alerting Only power policy. The following table lists
the SEL entries that are related to power redundancy policy changes.
