Known Issues

Warning Message Display

When used as a system controller and while used along with the Sun Dual FastEthernet/SCSI 6U CompactPCI Adapter with PMC, the Netra CP2160 board displays the following warning message:

WARNING: invalid vector intr: number 0x7c3

You can safely disregard this message.

Document Corrections

The following subsections contain corrections that need to be made to the Netra CP2160 documentation.

Inlet Temperature Sensor Readings

The Netra CP2000 and CP2100 Series CompactPCI Boards Programming Guide for Solaris Operating Environment (816-2485-13), page 62, contains the following paragraph:

Note that the inlet temperature sensor typically does not capture true board inlet temperature due to the heat of nearby components. For typical Sun systems, subtract 3°C to 6°C from this value to approximate true board inlet temperature. For non-Sun systems, a different value to obtain true board inlet temperature may be required.

Replace this paragraph with the following new paragraph:

Note that the inlet temperature sensor typically does not capture true board inlet temperature due to the heat of nearby components. For typical Netra CP2000/CP2100 series systems, subtract 4°C from the temperature sensor value. Note that the temperature sensor has an accuracy of up to plus or minus 2°C. Users should conduct their own temperature sensor tests to obtain accurate readings.

CPU Diode Terminology Change

The Netra CP2000 and CP2100 Series CompactPCI Boards Programming Guide for Solaris Operating Environment (816-2486-13) and the Netra CP2160 CompactPCI Board Installation and Technical Reference Manual (816-5772-10) both refer to monitoring the the CPU diode temperature on the Netra CP2160 board.

The term CPU diode does not accurately reflect the area where the CPU temperature sensor monitors the board temperature. It is more accurate to use the term CPU sensor in the document when referring to the location on the board near the CPU where the temperature is being monitored. The term CPU sensor should replace CPU diode wherever it occurs in the document.

TABLE 1 shows the locations in the technical reference manual and the programming guide where the CPU diode temperature measurements are referenced.

Changes in OpenBoot PROM Threshold Temperature Defaults for the Netra CP2160 Board

The default OpenBoot PROM threshold temperatures for the Netra CP2160 board have been adjusted for OpenBoot PROM version 1.0.10 and subsequent versions.

The default threshold temperatures for the Netra CP2160 board are listed in the in the Netra CP2000 and CP2100 Series CompactPCI Boards Programming Guide for Solaris Operating Environment (816-2485-13) and the Netra CP2160 CompactPCI Board Installation and Technical Reference Manual (816-5772-10) as follows:

• warning-temperature = 60° C
• critical-temperature = 65° C
• shutdown-temperature = 70° C

The new default threshold temperatures for Netra CP2160 boards using OpenBoot PROM version 1.0.10 and subsequent versions are as follows:

• warning-temperature = 70° C
• critical temperature = 75° C
• shutdown-temperature = 80° C

TABLE 2 shows the locations in the technical reference manual and the programming guide where the threshold default temperature references need to be changed for the Netra CP2160 board.

The following example values also need to be updated for the Netra CP2160 board in the Netra CP2000 and CP2100 Series CompactPCI Boards Programming Guide for Solaris Operating Environment (816-2485-13):

• Page 65, OpenBoot PROM warning temperature example value:
• Old example: ok setenv warning-temperature 61
• New example: ok setenv warning-temperature 71

• Page 65, OpenBoot PROM shutdown temperature example value:
• Old example: ok setenv shutdown-temperature 72
• New example: ok setenv shutdown-temperature 82

• Page 65, OpenBoot PROM critical temperature example value:
• Old example: ok setenv critical-temperature 66
• New example: ok setenv critical-temperature 76

• Page 67, Warning Temperature Response at OpenBoot PROM example:
• Old example: The current threshold setting is: 60;
  The current temperature is: 61
• New example: The current threshold setting is : 70;
  The current temperature is: 71

• Page 67, Critical Temperature Response at OpenBoot PROM example:
• Old example: The current threshold setting is: 65;
  The current temperature is: 66
• New example: The current threshold setting is : 75;
  The current temperature is: 76

DIP Switch Settings

In the Netra CP2160 CompactPCI Board Installation and Technical Reference Manual
(816-5772-10), Figure 5-24 on page 5-102 shows the DIP switch settings for the power module on the CP2160 board. You can disregard this illustration, as the DIP switch settings may have been set differently on your board in the factory.
