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. 

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.

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.
