1-18 Technical Information
POWER MANAGEMENT
Each system is Energy Star compliant and comes with the power-saving features enabled.
If the keyboard, mouse, or drives are not used after 15 minutes, the screen goes blank and
the system goes into a partial power shutdown. A blinking power lamp indicates that the
system is in the power-saving mode. As soon as activity is detected, the system resumes
where it left off.
The system can be manually put into a Suspend power-saving mode by pressing the
suspend button. The Suspend mode provides the greatest power savings by putting the
system in maximum power shutdown. When the system goes into Suspend mode, it saves
data and system status and then shuts off power to all possible components. A blinking
power lamp indicates that the system is in the power-saving mode. As soon as activity is
detected, the system resumes where it left off.
The amount of inactive time is adjustable. Power management can also be disabled. Both
can be set through Setup.
DESKTOP MANAGEMENT INTERFACE
The Desktop Management Interface (DMI) is the standard interface used to manage system
components on the computer. DMI acts as a layer of abstraction between management
applications and managed components such as systems, network cards, and printers.
With DMI, a management application (such as Hewlett Packards Openview), provides a
simplified method to collect information from different vendors computers operating on
the network.
DMI is not a protocol but an interface that complements network protocols like the Simple
Network Management Protocol (SNMP).
DMI Components
The NEC DMI consists of two major functional components:
n
the Component Interface (CI) module
n
the NEC DMI Browser.
The CI module provides the instrumentation and interface between the BIOS and the DMI
Service Layer (SL). The DMI Browser displays and manages existing attributes in the
Management Information Format (MIF) database. The Desktop Management Task Force
(DMTF) provides the DOS Service Layer, Windows Service Layer, and MIF database
structure.
