Power-up Diagnostics
The system automatically runs diagnostic software at
power up. This software verifies that every
component in the system is operating correctly.
If any component fails during power-up diagnostics,
the system either fails to power up or the faulty
module comes up but all of its ports are out of
service. When the system comes up, check to see
which modules, if any, have failed diagnostics by
checking the module LEDs or, if you are connected to
a workstation, by viewing the system configuration
display in the Administration Console.
During power up, the system processor LEDs provide
information on components in your system. See
Figure 24 for more information.
