Avaya M770 ATM Switch User’s Guide 269

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 Avaya 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 Avaya 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 Avaya 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 Avaya 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
Module 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.
