Command Mode

Command Usage
◆ The access point supports two software image files (A and B), one of which is
set as the boot image, or “Active” file, and the other acts as a “Backup” file.
◆ You can upgrade new access point software from a local file on the
management workstation, or from an FTP or TFTP server. The new software file
replaces the image (A or B) that is not currently set as the boot image.
◆ After upgrading new software, you must reboot the access point to implement
the new code. Until a reboot occurs, the access point will continue to run the
software it was using before the upgrade started. Also note that new software
that is incompatible with the current configuration automatically restores the
access point to the factory default settings when first activated after a reboot.
