Enclosure power management
Planning power management
The compute enclosures each contain twelve power supplies (six upper and six lower), which are
monitored directly by Onboard Administrator. At least one upper and one lower power supply
must be installed at all times.
Onboard Administrator is responsible for calculating the redundancy status, total available power,
and total power consumed. This information is displayed to the user and is used to manage power
resources. The Onboard Administrator power subsystem displays include status and information
for each power supply, and the power enclosure itself.
Also included in the power fault realm is control of the electronic fuses between the power backplane
and the server or switch bays. The Onboard Administrator will alert on fuse trips to enable you to
reset fuses manually.
When installing additional power supplies into the enclosure, different power supply part numbers
are not supported in the same enclosure. The Onboard Administrator identifies which power
supplies must be replaced by displaying a caution icon.
For proper installation of the power supplies into a compute enclosure, see the HP Integrity
Superdome 2 Installation Guide.
