The WAP device maintains two firmware images. One image is active and the other is
inactive. If the active image fails to load during bootup, the inactive image is loaded and
becomes the active image. You can also swap the primary and secondary images.
As new versions of the WAP device firmware become available, you can upgrade the firmware
on your devices to take advantage of new features and enhancements. The WAP device uses a
TFTP or HTTP client for firmware upgrades.
After you upload new firmware and the system reboots, the newly added firmware becomes
the primary image. If the upgrade fails, the original firmware remains as the primary image.
When you upgrade the firmware, the access point retains the existing configuration
information.
