specifications. The AC power supplies work with input voltages from 100 to 240 volts, making them
functional worldwide.
Through the HP ROM-Based Setup Utility (RBSU), you can select the operating mode for redundant
power supplies:
Balanced mode
tells the power supplies to provide power equally. It ensures full redundancy but
can result in lower power efficiency at reduced loads.
High Efficiency mode
tells the system to use one power supply at lower power consumption levels.
The second power supply stays online but does not supply power until needed.
Both modes provide full power redundancy in case of a power supply or circuit failure.
HP Intelligent Power Discovery
In data centers, server
failures can occur when the server’s redundant power sup
plies connect to the
wrong power outlets. A common mistake is to connect both power cords to the same power feed
circuit. The HP Intelligent Power Discovery (IPD) solution prevents server failures by identifying these
discrepancies so they can be corrected.
Our IPD solution automatically discovers the rack installation of ProLiant servers that use HP Common
Slot Platinum Power Supplies. Intelligent Power Discovery correlates each server
’s
identity and
location to a power outlet and
verifies the server’s power redundancy.
IPD includes:
An Intelligent Power Distribution Unit (iPDU) Core with six monitored C-19 outlets
An Intelligent Extension Bar with five monitored C-13 outlets
Power Line Communication (PLC) power cords with embedded RS-232 data lines
The iPDU Core has an embedded management module that lets you access power topology
information through a local GUI or remote HP Insight Control power management (ICpm) software.
With all of the IPD components connected, the iPDU immediately detects and connects to each
server’s iLO device before you power on the server. The iPDU management module gets the server’s
identity data and maps the server to an individual outlet. The iPDU core also sends its identity data to
each server’s iLO
device. In this way, each iPDU core keeps track of the servers plugged into its
outlets. And each iLO device knows its server’s rack location and electrical outlet.
