  • Page 99: Diagnostic Tools Overview

    Diagnostic tools overview The following tools are available to help you identify and resolve hardware-related problems: v POST beep codes, error messages, and error logs The power-on self-test (POST) generates beep codes and messages to indicate successful test completion or the detection of a problem (see “POST error logs” on page 90).

  • Page 100: Post Error Logs

    POST error logs When you turn on the server, it performs a series of tests to check the operation of server components and some of the options installed in the server. This series of tests is called the power-on self-test, or POST. If POST finishes without detecting any problems, a single beep sounds, and the first screen of the operating system or application program appears.

  • Page 101: Diagnostic Programs, Error Codes And Messages

    Diagnostic programs, error codes and messages The server diagnostic programs are stored in electrically erasable programmable read-only memory (EEPROM) on the system board that is shared with the BIOS code. These programs are the primary method of testing the major components of your server.

  • Page 102: Starting The Diagnostic Programs

    Starting the diagnostic programs Complete the following steps to start the diagnostic programs: 1. Turn off the server and any peripheral devices. 2. Turn on all attached devices; then, turn on the server. Note: To run the diagnostic programs, you must start the server with the highest level password that is set.

    Note: To save the test log to a diskette, you must use a diskette that you have formatted yourself; this function does not work with preformatted diskettes. If the diskette has sufficient space for the test log, the diskette may contain other data.

    The firmware update utility program updates the BMC firmware or SDR/FRU data only and does not affect any device drivers. Go to http://www.ibm.com/support/ to download the utility program; then, copy the flash.exe file to a firmware update diskette. Note: To ensure proper server operation, be sure to update the server BMC firmware code first before updating the BIOS code.

  • Page 106: Resetting The Bmc Firmware

    To update the firmware, use one of the following methods: ® v If the Linux or Windows operating-system update package is available from the World Wide Web and you have obtained the applicable update package, follow the instructions that come with the update package. v If you are using a diskette, complete the following steps: 1.

    If this happens, you will need a BIOS recovery diskette. To create this diskette, download the BIOS recovery disk image from http://www.ibm.com/support/ and follow the directions in the image’s included readme file. Using the BIOS recovery diskette, complete the following steps to recover the BIOS code: 1.
