3.Start POST diagnostics. Type:

ok post

The system runs the POST diagnostics and displays status and error messages via either the local serial terminal (ttya) or the redirected (system controller) system console.

4.Examine the POST output.

Each POST error message includes a “best guess” as to which field-replaceable unit (FRU) was the source of failure. In some cases, there may be more than one possible source, and these are listed in order of decreasing likelihood.

Note – Should the POST output contain code names and acronyms with which you are unfamiliar, see TABLE 6-13in “Reference for Terms in Diagnostic Output” on page 114.

What Next

Have a qualified service technician replace the FRU or FRUs indicated by POST error messages, if any. For replacement instructions, see:

■Sun Fire V490 Server Parts Installation and Removal Guide, which is included on the Sun Fire V490 Documentation CD

If the POST diagnostics did not disclose any problems, but your system does not start, try running the interactive OpenBoot Diagnostics tests.
