Item Description
System Input
Max Power
Capacity
Maximum input power that the available power supplies can supply
to the system (in watts).
Input
Redundancy
Reserve
Displays the amount of redundant power (in watts) in reserve that
can be utilized in the event of an AC grid or power supply unit
(PSU) failure.
When the chassis is configured to operate in AC Redundancy
mode, the Input Redundancy Reserve is the amount of reserve
power that can be utilized in the event of an AC grid failure.
When the chassis is configured to operate in Power Supply
Redundancy mode, the Input Redundancy Reserve is the
amount of reserve power that can be utilized in the event of a PSU
failure.
Input Power
Allocated to
Servers
Displays (in watts) the cumulative input power that the CMC
allocates to servers based on their configuration.
Input Power
Allocated to
Chassis
Infrastructure
Displays (in watts) the cumulative input power that the CMC
allocates to the chassis infrastructure (Fans, IO modules, iKVM,
CMC, Standby CMC and iDRAC on servers).
Total Input
Power Available
for Allocation
Displays the total chassis power, in watts, still available for
allocation.
Standby Input
Power Capacity
Displays the amount of standby input power (in watts) that is
available in the event of a Power Supply fault or Power Supply
removal from the system. This field may show readings when the
system has multiple power supplies and the Dynamic Power Supply
Engagement is enabled.
NOTE: It is possible to see a PSU in standby mode but not contribute
to the Standby Input Power Capacity value. In this case, the watts
from this PSU are contributing to the Total Input Power Available for
Allocation value.
