Understanding the Initialization Process
After powering on, the Cuda 12000 runs through a boot process that
includes both hardware and software diagnostics and initialization. During
this process, the on-board processors mounted on each application module
write initialization status messages to the 8-character LED display that is
located on the module faceplate. These status messages indicate the
initialization stage currently in process.
Similarly, whenever you install an individual module while the system is
operating, the newly installed module runs through the same initialization
process and displays the same status messages.
Figure 6-1 describes the various status messages that you may see during
this initialization process.
In addition to the messages listed in the tables below, any module with a
Pentium processor will display a series of POST codes while booting. Contact
ADC Customer Support for additional information regarding POST codes.
