You can configure HEM only through the RBSU. You cannot modify these settings through iLO.
Settings for HEM are Enabled or Disabled (also called Balanced Mode), and Odd or Even supplies
as primary. These settings are visible in the High Efficiency Mode & Standby Power Save Mode
section of the System Information>Power tab. This section displays the following information:

If HEM is enabled or disabled

Which power supplies are primary (if HEM is enabled)

Which power supplies do not support HEM

Graceful shutdown

The ability of the iLO 2 microprocessor to perform a graceful shutdown requires cooperation from
the operating system. In order to perform a graceful shutdown, the health driver must be loaded.
iLO 2 communicates with the health driver, and the appropriate operating system method of safely
shutting the system down to ensure data integrity is performed.

In cases where the health driver is not loaded, the iLO 2 processor attempts using the operating
system to perform a graceful shutdown through the power button. iLO 2 emulates a physical power
button press in order to prompt the operating system to shutdown gracefully. The behavior of the
operating system is dependent on its configuration and settings for a power button press.

The EAAS configuration of the HOST ROM RBSU allows for the disabling of this automatic shutdown
feature. This configuration allows for the disabling of the automatic shutdown event except for in
the most extreme conditions where physical damage would result.

Starting with Windows Server 2003, the computer group policy disables a graceful shutdown of
the system using a momentary press unless an Administrator is logged in to the operating system.
To change this setting and enable a graceful shutdown, do the following:

1.

From a command prompt, issue the command:

gpedit.misc

2.

Set Computer Configuration>Windows Settings>Security Settings>Local Policies>Security
Options>Shutdown. Allow the system to be shut down without having to log on to Enabled.
