Abstract: NETFINITY 5600: POSSIBLE POWER-ON PROBLEM

SYMPTOM:

When attempting to power on the system the video does not display and the system halts.

PROBLEM ISOLATION AIDS:

•  The system is any of the following IBM Netfinity servers:

   a Netfinity 5600 server, Type 8664, Models: 11Y, 1RY, 21Y, 2RY, 31Y or 3RY.

•  The system is configures with a 133MHz FSB Intel Pentium III processor.
•  The system has the described symptom.

FIX:

Intel plans to fix the problem with their 133MHz FSB (Front Side Bus) Pentium III processors in future production, however IBM is providing a workaround to the problem through the use of the onboard system management processor.

The IBM Netfinity 5600 Advanced System Management Processor Firmware Update Diskette Version 2.10 is available on the web to address this problem (P/N 09N8253A).

This code can be downloaded from the IBM Netfinity support web site at:

http://www.pc.ibm.com/searchfiles.html
search on "Netfinity 5600 Advanced System Management
Processor Firmware Update"

This code is then required to "flash" the Firmware on the system to the correct level.

Note: Detailed instructions on the update procedure are contained in the readme file on the downloadable diskette image.

WORKAROUND:

As an alternative to the System Management firmware upgrade, a workaround is to power off the system and then power on the system.
The system should boot up normally after the cold-boot.

DETAILS:

This behavior is due to a problem with the 133MHz FSB Intel processor.
This has been documented by Intel in an errata for the processor and is planned to be corrected in future processor production.
The System Management firmware will provide a workaround to the Intel Pentium III processor problem.
