Description
Item
The overall power status of the enclosure. Possible values
are Unknown, OK, Degraded, or Critical Error.
Power Subsystem Status
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.
Power Mode
The amount of watts being consumed by all devices in the
enclosure.
Present Power
The maximum amount of power available for consumption
by the enclosure measured in watts.
Power Limit
NOTE:
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 screen
To set the power management options in Onboard Administrator, go to the menu on the left and
select the enclosure to be managed, and then click
Power and Thermal
. The
Power Management
page appears below. Click
Power Management
to display the following choices:
•
AC Redundant
•
Power Supply Redundant
•
Not Redundant
Beneath the main power management choices is the Dynamic Power Savings mode check box
which enables you to enable Dynamic Power Savings Mode.
The AC Input VA Limit box enables you to set a VA limit for the enclosure. After this limit is met by
the enclosure, it will not allow any additional blades, power supplies, fans, or switches to power
on. If a value is entered into the VA Limit box that is lower than the now used VA for the enclosure,
the enclosure does 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.
NOTE:
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.
The HP Superdome 2 Enclosure power management system enables you to customize the
configuration of the enclosure. You can select from the different modes on the Onboard Administrator
Power Management screen. The power modes are explained in the following table.

Redundant
power supplies are used to provide redundancy (where N can equal
1, 2, or 3). Up to three upper and three lower power supplies can fail
without causing the enclosure to fail. When correctly wired with
redundant dc line feeds, this configuration also ensures that a dc line
feed failure does not cause the enclosure to power off.
