Appendix B
Using BOOT Loader
This appendix describes the commands that are available in the BOOT Loader
interface.
Start-up Process
During the normal boot-up process, the Cajun M770 ATM Switch monitors the
hardware for non-critical faults. If no problems are detected then the BOOT Loader
will not be activated. If a fault is detected then the BOOT Loader is enabled.
Note: The status indicators on the front panel of the Cajun M770 ATM Switch will
indicate any fault that has occurred during the start-up process. For more information
about the start-up test, refer to the
Modules’ Installation Guides .
Getting connected to the BOOT Loader
The BOOT Loader program will only be executed by the Cajun M770 ATM Switch,
if one of the following occurs:
• a fault is detected during hardware self test.
• by pressing, continuously, the
<−
and
−>
buttons on the module front panel at
the start of the boot-up process until the OPR LED turns OFF.
You can access the Cajun M770 BOOT Loader by direct connection on the serial
interface, using a VT100 terminal or a PC running a terminal emulation program.
For information about the default settings and pin-out of the serial port, see the
Modules’ Installation Guides.
When you have connected a VT100 terminal and the BOOT PROM software has
been executed, the terminal screen will display the BOOT MENU.
