Chapter 6. IBM System Management Tools
Advanced Configuration and Power Interfaces (ACPI)
Advanced Configuration and Power Interfaces (ACPI) will provide a standard means to integrate power
management features throughout a system, including hardware, operating systems, and application
software. With such integration and power management, the system can automatically turn off and on
peripherals such as CD-ROMs, network cards, hard disk drives and printers as well as consumer devices
connected to the PC, including VCRs, TVs, phones, and stereos. ACPI technology will also enable
peripherals to activate and deactivate the PC. Other ACPI specification points of emphasis include the
following:
ACPI specifies a register-level interface to core power management functions and a descriptive
interface for additional hardware features.
ACPI provides a generic system event mechanism for Plug and Play, in addition to an operating
system-independent interface for configuration control.
ACPI leverages Plug and Play BIOS data structures while providing a processor architecture
independent implementation-compatible with both Windows 95 and Windows NT.
ACPI represents the foundation of the Microsoft OnNow initiative. OnNow represents a system-wide
approach to system and device power control. OnNow is a term for a PC that is always on but
appears off and responds to user or other requests.
Wake on LAN
Enhances remote management by enabling file updating and asset tracking on powered-off
computers.
Permits remote system setup, updates and asset tracking to occur after hours and on weekends so
daily LAN traffic is kept to a minimum and users are not interrupted.
Helps increase productivity of LAN administrators and computer users.
Available on all current IBM IntelliStation E Pro models.
Wake on LAN is a technology that enables you to remotely manage the clients in your network even if
they have been turned off. With the need to provide consistent and timely updates, such a feature brings
new levels of control, simplicity and savings to LAN-based networks.
IBM IntelliStation E Pro offers many features designed to help reduce your total cost of doing business.
Working with Intel through the AMA, IBM has devised a number of ways to integrate system management
software with intelligent hardware. Wake on LAN, LANClient Control Manager (LCCM), IBM Netfinity
Manager and Intel LANDesk Client Manager are system management tools that work together to attack
your computing costs by allowing you to automate time-consuming, tedious PC management tasks and
schedule these tasks for a time that is the least disruptive to users. Wake on LAN turns on the networked
computers, and then your choice of these network management tools handles remote management
operations and asset tracking. As long as the computers in the network are Wake on LAN-enabled and
electricity is available, Wake on LAN can turn on any or all of the PCs in your network so that LCCM, IBM
Netfinity Manager or LANDesk can perform the management tasks you've defined.
Wake on LAN components
Wake on LAN requires the following components:
A Wake on LAN-enabled Token-Ring or Ethernet LAN adapter card
These adapters are either preinstalled, integrated on the system board, or can be installed on current
IBM IntelliStation E Pro computers. Support for both Token-Ring and Ethernet gives you a choice of
network types, while allowing you to change from one type to the other by simply changing adapter
cards.
