The server is shipped with a bootable diagnostics CD-ROM. This CD-ROM is designed so that the server boots using the Solaris OS on the CD-ROM and starts SunVTS software. Diagnostic tests run and write output to log files that the service technician can use to determine the problem with the server.
For information on SunVTS, see Using SunVTS Diagnostics Software in Sun Fire X4800 Server Diagnostics Guide.
