Installation Manual

The server must be powered on for the iLO firmware to determine the power microcontroller
firmware version.
Smart Storage Battery details
The following details are displayed on servers that support the Smart Storage Battery.
• Index—The battery index number.
• Present—Whether a battery is installed. The possible values are OK and Not Installed.
• Status—The battery status. The possible values are OK, Degraded, Failed, or Other.
• Model—The battery model number.
• Spare—The part number of the spare battery.
• Serial—The battery serial number.
• Capacity—The battery capacity.
• Firmware—The installed battery firmware version.
Power monitoring
iLO monitors the power supplies in the server to ensure the longest available uptime of the server
and operating system. Brownouts and other electrical conditions might affect power supplies, or
AC cords might be unplugged accidentally. These conditions result in a loss of redundancy if
redundant power supplies are configured, or result in a loss of operation if redundant power
supplies are not used. If a power supply hardware failure is detected or the AC power cord is
disconnected, events are recorded in the IML and LED indicators are used.
The iLO processor is an essential component of the Power Discovery Services infrastructure.
The iLO processor communicates with the Intelligent Power Distribution Unit attached to each
Platinum Plus power supply to determine rack and data center power redundancy. When the iLO
processor is part of the Power Discovery Services infrastructure, it intelligently reports external
server input power redundancy status and individual (internal) power supply status.

High Efficiency Mode
High Efficiency Mode improves the power efficiency of the server by placing the secondary power
supplies in standby mode. When the secondary power supplies are in standby mode, primary
power provides all DC power to the system. The power supplies are more efficient (more DC
output watts for each watt of AC input) at higher output levels, and the overall power efficiency
improves.
High Efficiency Mode does not affect power redundancy. If the primary power supplies fail, the
secondary power supplies immediately begin supplying DC power to the system, preventing any
downtime. You can configure redundant power supply modes only through the system RBSU or
the UEFI System Utilities. You cannot modify these settings through the iLO firmware.
If High Efficiency Mode is configured to use an unsupported mode, you might experience
decreased power supply efficiency.
For more information, see the system RBSU user guide or the UEFI System Utilities user guide.
