Power Management; Desktop Management Interface; Dmi Components - NEC POWERMATE V Service Manual

POWER MANAGEMENT

Systems come with the power-saving features enabled. If the keyboard, mouse, or drives
are not used after a pre-defined period of time, 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 Packard's Openview), provides a
simplified method to collect information from different venders 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:
T
the Component Interface (CI) module
T
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.
