Dell DiagOS Tools
This guide helps you use the Dell diagnostics operating system (DiagOS). The DiagOS is an environment that
provides a suite of tools that you can use to help diagnose issues seen on the system, or to run a general
health check to make sure the hardware is operating properly.
Diagnostic Tools
The DiagOS uses standard Linux drivers and contains the following tools you can use to evaluate the health of
your system. The tools are packaged for both the DiagOS, which is a simple OS of the same kernel version
and small rootfs to support the tools and drivers.
NOTE: By default, the system’s I/O modules are down. You must power up the I/O modules or the
Opticstool and NPUtool reports failures. For information about how to power up the I/O modules, see the
Dell Installation Guide for your system at http://www.dell.com/support.
