Diagnostics

116
The Silicon Graphics Prism Deskside visualization system is equipped with diagnostics
to test the system hardware and diagnose component/part failures. These diagnostics
are grouped into the following categories:
• Power-on diagnostics (POD)
Power-on diagnostics are PROM-resident tests that run automatically when you
power on the system. As the boot process discovers hardware components, it runs
power-on diagnostics to verify that each component that is needed to boot the
system is working correctly. Refer to "Power-on Diagnostics" on page 117 for more
information about POD.
•
Online diagnostics
Online diagnostics are tests that verify system hardware while the operating system
is running. To prevent data loss, you should use the online diagnostics only when
the system is idle. Refer to "Online Diagnostics" on page 118 for more information.
All diagnostics are loaded on your system when you receive it. To upgrade to future
revisions of the diagnostics, download the appropriate Customer Diagnostics package
from Supportfolio (http://support.sgi.com). Contact your service representative for
more information.
Note: The diagnostics described in this document run only on Silicon Graphics Prism
visualization systems. They will not work on any other SGI systems.
