Row Description
Thermal Subsystem Status The overall thermal status of the enclosure. Possible values are Unknown, OK,
Degraded, or Critical Error.
Power Subsystem Status The overall power status of the enclosure. Possible values are Unknown, OK,
Degraded, or Critical Error.
Power Mode
A user setting to configure the enclosure DC power capacity and the input power
redundancy mode of the enclosure. See Power Management for possible values.
Present Power
The amount of watts being consumed by all devices in the enclosure.
Power Limit
Enclosure Dynamic Power
Cap
The maximum amount of power available for consumption by the enclosure
measured in watts.
A power cap on a group of servers in the enclosure. As the servers run, the demand
for power varies for each server. A power cap for each server is set to provide the
server with enough power to meet its workload demands while still conforming to the
Enclosure Dynamic Power Cap. Continuous monitoring of power demands and
automatic adjustments to server power caps ensure there is minimal performance
degradation. Information for the Enclosure Dynamic Power Cap appears only if a
cap has been defined.
Present Power/Enclosure Dynamic Power Cap/Power Limit
The Present Power is the number of watts being consumed by all the devices in the enclosure. The Enclosure
Dynamic Power Cap automatically adjusts power caps on servers in the enclosure to meet workload
demands on the servers while still conforming to the Enclosure Dynamic Power Cap. The Power Limit is the
maximum amount of input power available for consumption by the enclosure. The Power Limit is dependent
on the enclosure power redundancy setting and the number and location of the power supplies in the
enclosure. If a Static Power Limit has been specified, the Power Limit displays that limit.
Power management
To set the power management options in Onboard Administrator, go to the menu on the left and select the
enclosure to be managed. Click Power and Thermal>Power Management. The main Power Management
page appears and displays the following choices:
• AC Redundant
• Power Supply Redundant
• Not Redundant
Beneath the main power management choices is the Dynamic Power Savings mode checkbox which allows
you to enable Dynamic Power Savings Mode.
The AC Input VA Limit field enables you to set a VA limit for the enclosure. After this limit is met by the
enclosure, it will not allow any further blades, power supplies, fans, or switches to power on. If a value is
entered into the VA Limit field that is lower than the currently used VA for the enclosure, the enclosure will not
power off any devices within the enclosure. However, if a device is powered off, it cannot power on because
of the VA limit rule set in the Onboard Administrator power management settings.
IMPORTANT: If redundancy mode is set to Redundant, AC Redundant, or Power Supply
Redundant, and power redundancy is lost, then you must either add additional power supplies or
change the redundancy mode setting in the Onboard Administrator to restore Power Subsystem
status. See the Insight Display for corrective steps.
