Package contents

The IBM 16/4 Token-Ring Low Profile PCI Management Adapter comes with the
following features:
v Automatic Configuration and Power Interface (ACPI)/PCI power management
v Wake on LAN feature
These features are described in the following sections.

Automatic Configuration and Power Interface (ACPI)

If your computer supports ACPI, then it has built-in energy-saving capabilities.
When ACPI is enabled (usually through the computer BIOS settings), the operating
system is allowed to control the power management features of your computer. Not
all operating systems support ACPI BIOS mode. Refer to your operating system
documentation to determine if ACPI is supported. Refer to your computer system
documentation to determine if ACPI BIOS is offered and the method by which it can
be enabled. The adapter implements the PCI Bus Power Management Interface
Specification Version 1.0 that works together with ACPI. Under control of the
operating system, the adapter (and the entire system) can be placed in various
power-saving modes and be dynamically configured to look for network
protocol-specific events. Upon detection of these events, the adapter can signal a
wake-up condition which will bring the system to a fully-powered (operational) state.
Some systems might need to be configured through BIOS settings
(configuration/setup utilities) to allow PCI devices to wake a system. Refer to your
computer system documentation for automatic power-on feature settings (or PCI
wake-up features).

Wake on LAN

Adapters that support this feature can turn on a system that is powered off. The
adapter uses an auxiliary 3-volt power pin that is available on the PCI bus
beginning with PCI version 2.2. No additional auxiliary power cables are required.
The 3-volt PCI auxiliary power pin supplies power to the adapter. A control register
on the adapter determines whether the adapter is powered on by the 3-volt auxiliary
power source. This register is controlled by the system BIOS. If the BIOS enables
the control register bit, then the adapter always has a source of power, even when
the system is powered off (system power cord is connected to a live power outlet).
When the system is powered off, the adapter automatically inserts into the network
and looks for a special frame. This frame is commonly referred to as a magic
packet. Upon detection of the magic packet, the adapter signals the system to turn
on the power supply, thus turning on the computer system. The magic packet is a
frame sent by another computer system usually running an application that provides
remote system management.
