Hot-Plug Power Supplies - HP ProLiant DL580 Setup And Installation Manual

Hot-Plug Power Supplies

Improved power supply performance ensures that a single power supply provides
sufficient power to the entire system. Complete redundancy can be achieved by
installing an additional hot-plug power supply.
The standard and redundant 800-W power supplies run simultaneously under normal
operating conditions. The redundant hot-plug power supply ensures the delivery of
electricity to the server, provides rapid serviceability, and minimizes the risk of
system interruption.
In case of a loss of redundancy, the system sends an alert of the failure to the system
administrator. The failure does not cause any loss of power, and the failed unit can be
replaced without having to power down the server or save system data. Power supply
features include:
•
Support for hot-plug redundant capabilities with the second power supply
installed (optional on some models)
•
Accessible from the front of the server
Hot-plug power supplies also have advanced features that ease operation:
•
Auto Line Sensing capability automatically selects the appropriate line voltage.
•
Power Down Manager ensures that ProLiant DL580 Generation 2 servers
deactivate in a manner that safeguards data and system integrity.
