Wireless Controller
Upgrade the Firmware
The wireless controller provides two methods for upgrading its firmware:
Scheduled, automatic update
Manual update
The wireless controller lets you retain two firmware versions in permanent storage (in the
active partition and in the backup partition) so that you can switch from one firmware version
to another
.
You can select which firmware version to load during the next boot cycle and
which firmware version to upgrade.
You can configure the wireless controller to download firmware from a TFTP or FTP server
and upgrade the firmware on the wireless controller when it is least disruptive. Y
ou can also
download firmware manually to a computer and upload it to the wireless controller from a
local file.
Note: In some cases, such as a major firmware upgrade, you might need to
erase the configuration and manually reconfigure the wireless
controller after the firmware upgrade. To find out if you must
reconfigure the wireless controller, see the release notes for the
firmware version.
IMPORTANT:
If your wireless controller runs a 3.x or 4.x firmware version and
you want to upgrade to a 5.x version, you must upgrade the
firmware by using a TFTP or FTP server. You cannot upgrade the
firmware from a local file.
Note: For information about upgrading firmware in a stacked redundancy
group, see Upgrade Firmware in a Stacked Redundancy Group on
page 315.
