1-24 Technical Information
Using DMI
As a part of the LANDesk Client Manager, the Desktop Management Interface (DMI) is
the standard interface used to manage system components on the computer. Examples of
system components are network interface cards, printers, and software applications. System
components provide a Management Information Format (MIF) file to be DMI compliant.
The information file describes component attributes that can be managed.
Client Mananger can be used to “get” attribute information on system components. It can
also be used to “set” attribute values in real time.
Heceta Capabilities
The computer has an Intel Heceta Head ASIC chip mounted on the system board. The
purpose of this chip is to provide real-time monitoring capabilities used by DMI. The
Heceta chip provides the following features:
„
an integrated temperature sensor with configurable interrupt generation based on
upper and lower temperature limits
„
a power supply monitor with configurable interrupt generation based on upper
and lower voltage limits
„
chassis intrusion detection with interrupt generation capabilities
To take advantage of these features, DMI has expanded its interface in the following areas:
„
Heceta interrupts may be enabled or disabled
„
High and low limits can be set and are displayed for temperature and power
supply voltages
„
Current readings are displayed for temperature, power supply voltages, and
chassis state
„
Heceta interrupts can be detected when “out of range” conditions occur. User
prompts are displayed to alert the user of a potentially harmful condition.
