What is Platform Instrumentation Control?
Platform Instrumentation Control (PIC) uses the Desktop Management Interface (DMI) 2.0
framework to manage Windows†2000 Advanced Server , or Linux Red Hat 7.1 and Red Hat
Enterprise Linux AS 2.1 server hardware components. PIC provides real-time monitoring and
alerting for server hardware sensors.
PIC has two main software components:
• The managed server: Platform Instrumentation (PI) is installed on the Windows 2000
Advanced Server, Linux Red Hat 7.1 server or Red Hat Enterprise Linux AS 2.1 that is going
to be managed by the PIC Console software.
• The managing console: PIC Console software is installed on the user console that will
manage the server.
On a Windows 2000 Advanced Server network, it is possible to install both parts of the software on
the same server. It is also possible to install both the Server Instrumentation and the
Console software on multiple systems.
Features
The following list summarizes the features of PIC:
• Graphical user interface
• Consolidated server health information
• Interchassis management via the Intelligent Chassis Management Bus (ICMB)
• Enterprise System Management Console (ESMC) integration, which means that PIC can run
under HP OpenView†Network Node Manager 6.1; or CA-Unicenter†TNG 2.4, as well as
under the ISC Console provided with ISC software.
• Remote installation of the server software (depending on the OS)
• RPC-based transport mechanisms
• DMI 2.0 service providers
System administrators can use PIC to:
• Remotely monitor server hardware sensors
• Configure sensor thresholds
• Update the server’s LCD display (if available)
• Configure, receive, and act upon alert events in the system event log (SEL)
• Configure audio or visual notifications in response to an event
• Configure options to shut down, reboot, or power-off the system automatically in response
to an event

Intel Platform Instrumentation Control (PIC) Console User's Guide

Tracking System Status
Using PIC, you are able to track system status and manage hardware conditions such as:
• Temperature
• Voltage
• Cooling fan status
• Chassis intrusion
• ECC memory
• Processor status
• Power supply status
• PCI Hot Plug (PHP) slot status
Some of these conditions have a threshold or range of acceptable values. Default values are
configured during system manufacturing. These values, along with the current readings, error
status, and timer settings, can be configured and monitored through PIC. An event occurs when a
parameter crosses a defined threshold. At the time an event occurs, PIC initiates the action you
have configured.
For example, if the temperature reaches a level that is outside of the user-defined threshold, an
event has occurred. You can configure PIC to respond to this event in multiple ways, such as:
• Display a message or sound an alert
• Shut down the server
• Record the event in a system log
You can also use PIC to view:
• System hardware inventory
• BIOS and system slot information
• Onboard Adaptec†SCSI controller status
• Onboard LSI†(Symbios) SCSI controller status
• Onboard QLogic†SCSI controller status
• Onboard Promise†IDE controller status
• Onboard Intel®LAN adapter status
Managing Third-Party Components, DMI, and MIF Files
PIC uses the Desktop Management Interface (DMI) to monitor components, such as hardware
sensors, inventory information, and third-party instrumentation on server systems. PIC monitors
the motherboard, chassis, onboard Adaptec, LSI (Symbios) and QLogic SCSI controllers, onboard
LAN adapters, and onboard Promise IDE controllers.
To provide these capabilities, each DMI-enabled component must provide a Management
Information Format (MIF) file, which describes the manageable attributes of that component. For
example, the current reading of a temperature sensor is an attribute that could be listed in a
MIF file.
The PIC Console GUI running on a local management console (Windows 2000 Advanced Server)
can manage components on a remote managed server(Windows 2000 Advanced Server. PIC also
includes a translator to allow management of the DMI-enabled component instrumentation from a
remote SNMP application.

For more information on DMI, see the Desktop Management Task Force (http://www.dmtf.org) on
the World Wide Web.

Launching PIC
PIC can be launched from and can manage servers from one of these management environments:
• H-P Network Node Manager
• CA-Unicenter TNG
• Intel Server Control (ISC) Console
Once the PIC GUI application is launched from a management console, the management console
application can terminate, and PIC will continue to operate normally.
H-P OpenView Network Node Manager
The H-P Network Node Manager Console autodetects servers that are capable of supporting one or
more of the ISC applications. The ISC applications currently supported include PIC, DPC, DMI
Explorer, and CSSU. The Console updates the server bitmap with an ISC server icon for those
servers capable of supporting one or more of the ISC applications. The PIC application will be
included, provided the server is running Platform Instrumentation.
To launch PIC, select an ISC-enabled server on the H-P Console network map, and then select the
"Platform Instrumentation Control Applet" option from the Tools Menu. Alternatively, you can
launch the PIC application by selecting an ISC-enabled server on the H-P console network map,
clicking the right mouse button, selecting “Launch ISC” and then selecting the "Intel, Platform
Instrumentation Control" option from the popup menu.
CA-Unicenter TNG
The CA-Unicenter TNG Console autodetects servers that are capable of supporting one or more of
the ISC applications. The ISC applications currently supported include PIC, DPC, DMI Explorer,
and CSSU. Autodetection of servers capable of supporting PIC will occur if the ISC-TNG
AutoDiscovery service is running on the console and the server is running Platform
Instrumentation. The ISC-TNG AutoDiscovery service should start automatically after installation.
It is possible to start this service manually if the need arises from either the TNG Unicenter "Auto
Discovery" dialog or from the Windows "Services" utility.
The ISC-TNG AutoDiscovery service creates a new ISC object in the CA Unicenter TNG user
interface for each server running the Platform Instrumentation software. That ISC object displays
on the map as a child of the "ISC World View" and as a child of the ISC-enabled server. You can
view all ISC-enabled servers under the "ISC World View."
To launch the PIC application, right-click on an ISC icon and select the “Launch ISC" option. A
popup menu will appear from which “Intel, Platform Instrumentation Control” can be selected
which will launch the PIC application.

10
Intel®Server Control (ISC) Console
The Intel Server Control (ISC) Console is a management console that provides basic server
management without having to use an enterprise system management console (such as H-P
OpenView) or a workgroup management console (such as LANDesk Server Manager).
To launch PIC from within the ISC Console, click the PIC icon in the Tool Pane.

Intel Platform Instrumentation Control (PIC) Console User's Guide

Using PIC
When you start PIC, the main window displays a tree view. You can expand the view to show the
sensor types supported on the managed server and further expand it to display detailed sensor
information.
A presentation area on the main PIC window displays current readings, threshold configurations,
inventory, and other related information for selections made in the tree view. The main window
also displays the server’s LCD (if available) and a picture of the PIC bitmap.
Most of the PIC sensors have associated thresholds that trigger alert actions when the thresholds
are crossed. You can:
• Specify which alert actions you want to occur.
• Modify the default thresholds.
• Configure the default actions and notifications for each threshold.
When a parameter crosses a threshold, you can have PIC:
• Beep the speaker on the managed server.
• Display an alert on the managed server.
• Log the event to disk on the managed server.
• Broadcast a message.
• Write a message to the LCD on the managed server.
• Page an administrator.
• Use one of the shutdown/power control options to shutdown the OS, do a hardware reset, or
power-off the server.
The PIC Console Main Screen
PIC uses a Windows Explorer-like model, with a navigation pane (tree view) at the window left
and a presentation pane (list view) at the window right. When you select a sensor from the tree, the
presentation pane shows a set of tabbed pages with sensor-specific information.
The main screen of the PIC application is continually updated to show current sensor status.
Specific PIC sensor dialogs (such as temperature and voltage sensors) show the current sensor
reading when displayed and are updated dynamically during refresh.

13
Toolbar
The toolbar allows quick access to some menu items. To hide the icon toolbar, click the right
mouse button over the toolbar, and then click the Hide item that appears.
Navigation Pane
The Navigation Pane shows a tree view of server components that can be monitored. Many
branches of the tree represent group components that have subbranches (nodes). These group items
are identified by the tree expansion icons (“+” or “-”) appearing to the left of the component name.
These branches can be expanded to list nodes (detail sensor list) or collapsed to hide nodes.
Server BitMap
The Server Bitmap shows a picture of the server splash screen. To hide the picture, click the right
mouse button over the picture, and then click on the “Hide” popup menu that appears.
LCD Display
The LCD Display Pane shows the actual server LCD contents and a button to set the LCD contents
on the server. If the server hardware does not support LCD, the pane does not display.
Status Bar
The Status Bar displays status messages. To hide the status bar, click the right mouse button over
the status bar, and then click on the “Hide” popup menu that appears.

14
Presentation Pane
When you select a branch (group component) in the navigation pane, the presentation pane
displays a set of icons (list view) representing each group node (detail sensor list). The detail view
provides more information on each node item. You can arrange these list view items by name
(sorted alphabetically) or by status (sorted by current status: critical, noncritical, and OK). To
change the presentation pane, click the right mouse button over the pane, and then select from the
popup menu that appears. This popup menu has two items:
• View------Changes between large icons, small icons, list, or detail view
• Arrange Icons------Arranges the list view icons by name or status
When you select a node in the navigation pane, the presentation pane displays a set of tab pages
representing the detail sensor information. Depending on the node selected in the navigation pane,
one of the following four pages is displayed:
• Sensor Settings------Displays the sensor’s current status and current value, threshold values
and error counts.
Use this screen to configure new threshold values (such as Upper Critical Threshold, Upper
Noncritical Threshold).
The sensor status is also represented as a colored “Health” icon: Red is critical, Yellow is
noncritical, Green is OK, and Blue is an unsupported sensor.
• Alert Actions------Displays the currently configured alert actions for each threshold type (such
as Voltage-Status Changed to Upper Critical, Voltage-Status Changed to Lower Critical).
Use this screen to change the alert actions for each supported threshold. The factory default
alert actions are Log the Event to Disk and Write a Message to the LCD.
Sensor Information------Displays individual sensor information (such as Sensor Tolerance,
Maximum Reading, Minimum Reading).
• Inventory Information------Displays inventory information for the sensor (such as
Description, Manufacturer). The information varies based on the sensor type.
Sensor Dialogs
Alert Actions
All of the sensor dialogs have an Alert Actions tab. Use this tab to specify the actions to be taken
in the event of an alert on the associated sensor.
The factory default alert actions are to log the event to disk and to write a message to the server’s
front-panel LCD.

Intel Platform Instrumentation Control (PIC) Console User's Guide
15
Sensor Information
Each sensor has a sensor information tab that displays individual sensor information, such as
specifications and reading extremes.
Inventory
Each sensor has an inventory information tab that shows information about the sensor.
Health
Information about all unhealthy sensors is copied under the Health branch. Select the Health
branch of the server tree in the navigation pane to get a quick and simple view of the current server
health. If, for example, a 12V voltage sensor indicates that the current status is not OK, then data
about that 12V sensor is added to the Health branch of the tree. You can select the 12V entry in
either the Health or Voltage branch of the tree to display information about the sensor.
All sensors in either a critical or noncritical condition will appear in the Health branch of the tree in
addition to their normal location in other areas of the navigation tree. In this way, you can get a
quick summary of problem areas on your server and begin corrective actions.
Colored icons in the Health branch of the server tree indicate individual sensor status and overall
server status:
• Green: healthy server
• Yellow: noncritical conditions
• Red: critical failures
• Blue Question Mark: unsupported sensors
The color of the overall server health icon will display the state of the most severe sensor status. If
any sensor is in a critical condition (regardless of other sensors being in a noncritical condition),
the server health status will be shown as critical (red). If there are only noncritical sensors, the
server health status will be shown as noncritical (yellow). If all sensors report normal conditions,
the server health status will be shown as OK (green).
Chassis
PIC monitors chassis door open/closed switches for managed servers that support this feature. The
number of sensors monitored depends on the server chassis.
The chassis intrusion sensor screen displays the current security status. Not all servers support this
component.
When a chassis door that includes an open/close switch is opened, the vulnerable state is indicated
as a critical condition in the health branch of the PIC Console, and the requested event actions are
carried out. When all chassis doors that include an open/close switch are closed, PIC indicates the
chassis is secure and carries out the requested event actions.
For systems that do not support chassis open/closed switches, this portion of the PIC Console will
either not display or the chassis status will be reported as “Unknown.”

16
Fan
The fan sensor screen displays actual fan RPM for systems that support this feature. The threshold
appears in terms of the RPM value. If the current fan RPM value falls below the specified
threshold value, then the sensor status changes and an event generates. For the systems that do not
support fan RPM threshold, the threshold setting is 0 and read-only. If the fan stops, then the
sensor status changes and an event generates.
PIC monitors two types of fans:
• Rotation-sensing fans—PIC can detect whether a fan has stopped but is not able to indicate
which fan has failed. These fans, together, are treated as a single fan unit. Therefore, event
actions must be configured for all fans together, rather than separately.
• RPM-sensing fans—PIC can detect whether an individual fan has either slowed or stopped
and will display the actual fan RPM value for systems that support this feature. Each
RPM-sensing fan is independently configurable with its own threshold and event actions.
If a rotation-sensing fan fails or an RPM-sensing fan crosses a threshold, the PIC Console displays
the event as a critical condition via the health branch of the software, and the requested event
actions are carried out.
For systems that do not support a fan RPM threshold, the threshold setting displays a “0” and is
read-only in the PIC Console display.
ICMB
The ICMB dialog allows you to configure options for the Intelligent Chassis Management
Bus (ICMB).
The ICMB feature allows multiple remote devices to be interconnected and management
information shared among them. For example, your managed server could be configured to be an
ICMB primary server and report management information on other ICMB devices connected to it.
Using ICMB, PIC can manage the power state of remote ICMB devices and view FRU information
about those devices. The amount of FRU information available depends on the type of ICMB
device you are trying to manage.
Through the PIC Console, you can switch your view of the primary managed server to one of the
ICMB-managed devices and view the available information on that device without losing the
connection with the primary server. You can change your view back to the primary server or any
other ICMB-managed device at any time. Through the PIC Console, you can configure the ICMB
management features of the primary managed server and the remote ICMB-managed devices.
• Local ICMB Server Configuration------With this option it is possible to enable the local
server as a management point, enable the full sensor view of remote devices, and change the
discovery period for remote devices.
• Remote ICMB Chassis Configuration------With this option it is possible to configure each
remote device discovered via ICMB. You can decide whether to manage the remote device,
enable full sensor view for the remote device, and set the event polling rate for the remote
device.

Intel Platform Instrumentation Control (PIC) Console User's Guide
17
You can reclaim inactive ICMB system resources on the primary server. Doing so frees the
memory taken up by the SDR and FRU information on the primary server for any remote device
that is no longer visible on the network (via ICMB).
Memory Array
The memory array sensor screen displays information and status about each memory array.
Sensor-specific information is displayed in the Sensor Information tabbed page. Not all servers
support this component.
Memory Device
The memory device sensor screen displays information and status about each memory device.
Sensor-specific information is displayed in the Sensor Information tabbed page. Not all servers
support this component.
PCI HotPlug Device
The PCI HotPlug Device sensor screen displays information about each PCI Hot Plug device
installed in a PHP slot. If the server hardware does not support PCI HotPlug it will not appear in
the navigation pane and the screen will not be available.
Power Supply
The power supply sensor screen displays information and status about each power supply.
Sensor-specific information is displayed in the Sensor Information tabbed page. Not all servers
support this function.
Power Unit
For systems that support it, PIC monitors the status of the power supplies in the managed server.
Each power supply is independently configurable for event actions upon failure. The power unit
sensor screen displays information and status about each power unit. Not all servers support this
component.
If a power supply reports a predictive failure condition, then PIC reports the status as a non-critical
condition in the health branch of the PIC Console software, and the requested event actions are
carried out.
If a power supply fails, the failure is reported as a critical condition in the health branch of the PIC
Console software, and the requested event actions are carried out. PIC also reports the system
power as nonredundant and as a noncritical condition in the health branch of the PIC Console
software, and the requested event actions are carried out.
For systems that do not support power supply sensors, this portion of the PIC Console software
will not display.

18
For those systems that support it, PIC monitors the managed server’s system power redundancy
status.
If a power supply fails or if the surplus power on the system is less than the amount provided by
one power supply, PIC reports that the system power is nonredundant. This condition is indicated
with a noncritical status in the health branch of the PIC Console software and the requested event
actions are carried out.
Processor
The processor sensor screen displays information and status about each processor. From this
screen, you can find out the type and speed of the processor. Sensor-specific information is
displayed in the Sensor Information tabbed page. Not all servers support this function.
For motherboards that support it, PIC monitors processor failures during runtime and system boot
on the managed server. If a supported motherboard includes multiple processors, each processor
can be configured and monitored separately through PIC. If a processor failure is detected, the
failure is reported as a critical condition in the health branch of the PIC Console software, and the
requested event actions are carried out.
If processor sensors are not available on the motherboard, this portion of the PIC Console does not
display.
System Slots
ISC gathers sensor information and slot status on all slots in your managed server. The slots are
categorized into two groups:
• PCI Hot Plug (PHP) slots (if the server hardware supports PCI HotPlug).
• All other non-PHP system slots.
Slot names containing “PCI 64bit” identify PHP slots. For PHP slots, there are three pages
available in the presentation pane: Sensor Information page, Sensor Status page, and Alert
Action page.
For non-PHP slots, only the Sensor Information pages displays.
System Information
PIC gathers information on field replaceable unit (FRU) components installed in your managed
server. This information includes a component description, manufacturer, model, part number,
component number, serial number, and revision level. PIC also gathers information on other
system resources including Operating System, BIOS, and the System Event Log.
The inventory screen displays a list of components within the system. The inventory list shows the
description, manufacturer, model number, part number, serial number, and revision level of
baseboard components. The inventory list will include information on the baseboard, processor
board, chassis, power share board, hot-swap backplane, and memory devices.
If your server does not support one or more of these features, these portions of the PIC Console
will not display.

Intel Platform Instrumentation Control (PIC) Console User's Guide
19
Temperature
The temperature dialog contains all temperature sensors. You can see individual sensor
information in the presentation pane by selecting the corresponding sensor node from the
navigation tree. You can monitor current temperature readings, current status, sensor error counts,
and set sensor thresholds. Depending on the individual temperature sensor and the server platform,
some thresholds are unsupported and they appear disabled, grayed out, in the control. The status
indicator in the upper left-hand corner shows the current status: a red stop sign means “Critical,” a
yellow caution sign means “Non-Critical,” and a green traffic light means “OK.”
The following table displays the information available for the temperature sensors.
Item Description
Maximum Reading The highest reading supported on this sensor.
Minimum Reading The lowest reading supported on this sensor.
Sensor Accuracy The sensor’s accuracy in +/- hundredths of a percent.
Sensor Tolerance (plus) The amount of variation over the actual value that can be reported.
Sensor Tolerance (minus) The amount of variation under the actual value that can be reported.
Sensor Resolution The smallest unit of measurement reported by the sensor.
Nominal Reading The expected normal reading for this sensor.
Lowest Normal Reading The lowest normal reading of this sensor. Readings below this value indicate
an abnormal condition.
Highest Normal Reading The highest normal reading of this sensor. Readings above this value indicate
an abnormal condition.
Interaction with Third-Party Components
You can configure event actions for DMI indications generated by third-party Server
Instrumentation installed with PIC. You can also monitor third-party instrumentation via the DMI
Explorer Interface. PIC supports event configuration for Adaptec SCSI, LSI (Symbios) SCSI,
QLogic SCSI, Promise IDE, and LAN Adapter Server Instrumentation.
Voltage
In a managed server, PIC monitors many types of voltage sensors; the number and type depend on
the server hardware configuration. Each monitored voltage sensor has independently configurable
thresholds and event actions. Example voltage sensors are:
• 12V, 5V, 3.5V, 3.3V, -5V, -12V
• Processors 1.5V and 2.5V
• SCSI A Termination 1, 2, and 3
The voltage dialog contains all voltage sensors. You can see individual sensor information in the
presentation pane by selecting the corresponding sensor node from the navigation tree. With this
control, you can monitor current readings, current status, sensor error counts, and set sensor
thresholds. Depending on the individual voltage sensor and the server platform, some thresholds
are unsupported and they appear disabled (grayed out) in the control. The indicator in the left-hand

20
corner shows the current status: a red stop sign means “Critical,” a yellow caution sign means
“Non-Critical,” and a green traffic light means “OK.”
The following table displays the information available for the voltage sensors.
Item Description
Maximum Reading The highest reading supported on this sensor.
Minimum Reading The lowest reading supported on this sensor.
Sensor Accuracy The sensor’s accuracy in +/- hundredths of a percent.
Sensor Tolerance (plus) The amount of variation over the actual value that can be reported.
Sensor Tolerance (minus) The amount of variation under the actual value that can be reported.
Sensor Resolution The smallest unit of measurement reported by the sensor.
Nominal Reading The expected normal reading for this sensor.
