Notes:

1.Depending on your server configuration, some of the error codes might not appear when you run the diagnostic programs.

2.If diagnostic error codes appear that are not listed in the tables, make sure that your server has the latest levels of SAL/EFI code, Remote Supervisor Adapter, and diagnostics microcode installed.

Small computer system interface (SCSI) messages

If you receive a SCSI error message, see “SCSI error messages” on page 184.

Note: If your server does not have a hard disk drive, ignore any message that indicates that the SAL/EFI is not installed.

Recovering SAL/EFI code

If the SAL/EFI code has become damaged, such as from a power failure during a flash update, you can recover the SAL/EFI code using the SAL/EFI code page jumper (J28 on the I/O board) and the recovery program on the Resource CD that comes with the xSeries 450 server.

You can download the latest version of the SAL/EFI flash utility program from the World Wide Web. Go to http;//www.ibm.com/eserver/xseries/, click IBM Server Support, and make the selections for the server.

To perform a full recovery of the SAL/EFI code, complete the following steps:

1.Review the safety information beginning on page 197.

Attention: When you handle static-sensitive devices, take precautions to avoid damage from static electricity. For details about handling these devices, see “Handling static-sensitive devices” on page 78.

Note: You will not see anything displayed on the monitor when you perform this procedure.

2.Insert the Resource CD into the DVD/CD-RW drive.

3.Turn off the server and peripheral devices, and disconnect all external cables and power cords; then, open the cover (see “Opening the cover” on page 88).

4.Remove fans 3 and 4. For instructions, see “Replacing fan 3 or 4” on page 108.

5.Locate the SAL/EFI code page jumper (J28) on the I/O board.
