Backing Up the Current Software
The Avaya Multiservice switches have two memory locations for
storing the embedded switch software: APP1 and APP2. These two
memory locations make it possible to store the current software in
one APP location and download the new software to the other APP
location.
Saving the current software in one APP location ensures that you
could run this earlier version of software, if you encounter any
problem with the new, downloaded software.
Web Agent
Procedure
To determine the APP location from which the switch loads the
previous version of software:
1. In the navigation pane, expand the System > Memory
folders.
2. Select FEPROM.
The FEPROM Contents Web page is displayed in the content
pane (Figure A-183). The Power-Up/Reset Image field
displays the APP memory location from which the switch
loads the switch software.
