Approaches for Software Maintenance
You can maintain the access controller in one of the following three ways:
z
Upgrade BootWare and application files using the XMODEM protocol through a serial interface.
z
Upgrade application files using TFTP/FTP through an Ethernet interface on the BootWare menu.
z
Upload/download application files and configuration files using TFTP/FTP through command lines.
z
The BootWare program is upgraded together with the host software program version. That is, the
system automatically upgrades the BootWare program when you upgrade the host software
program.
z
Before upgrading the software of your access controller, check the current BootWare version and
application program version to make sure that the correct file is used for the upgrade. For the
association between the host software version and the BootWare version, refer to the version
compatibility matrix in Release Notes.
