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.
