input/output (I/O) ports. You can configure the serial ports; configure remote
console redirection; enable or disable integrated Ethernet controllers, the
SAS/SATA controller, SATA optical drive channels, and PCI slots; and view
the system Ethernet MAC addresses. If you disable a device, it cannot be
configured, and the operating system will not be able to detect it (this is
equivalent to disconnecting the device).
– Power

- Active Energy Manager
Select this choice to enable or disable power capping. If you enable power
capping, the Active Energy Manager program will limit the maximum
power that is consumed by the server.

will be restored after a power outage occurs. You can select Always on,
Always off,orRestore to restore the server the state it was in at the time
of the power outage.
– Operating Modes
Select this choice to select the memory speed or to specify a preset operating
mode to configure the server for maximum power savings, maximum
efficiency, or maximum performance.
- Efficiency mode
Select this choice to maintain the optimal balance between performance and
power consumption. The server generally produces the best performance
per watt while it is in this mode.
- Acoustic mode
Select this choice to configure the server to draw the minimum amount of
power and generate the least noise. Server performance might be degraded
depending on the application that you are running.
- Performance mode
Select this choice to achieve the highest absolute performance for most
server applications. The power consumption in this mode is often higher
than in the Efficiency or Acoustics mode.
- Custom mode
Select this choice only if you understand the functions of the low-level
IMM settings. This is the only choice that enables you to change the
low-level IMM settings that affect the performance and power consumption
of the server.
– Integrated Management Module
Select this choice to view or change the settings for the integrated
management module.
