Switching the Primary and Secondary Management Software Images
The access point maintains primary and secondary images of the 
management software in flash memory. The primary image is used during 
normal operations. If the access point encounters a problem with the 
primary image when it is powered on or reset, it loads the secondary 
image instead and enters an event message in the log file to signal the 
problem with the primary image.
If you reset or power cycle the access point, the device again tries to load 
the primary again, and again switches to the secondary image if it cannot 
load the primary image.
If this problem keeps occurring, you can instruct the access point to switch 
the images, so that the secondary image becomes the primary image, and 
the primary image becomes the secondary image.
Caution
This procedure is disruptive to the wireless network because the 
access point does not forward traffic for approximately two minutes 
while it switches the images. To minimize the disruption to the 
wireless clients, you should perform this procedure during non-
business hours.
To switch the primary and secondary images, perform the following 
procedure:
1. From the Maintenance menu, select Upgrade.
The management software displays the “Manage firmware” window, 
shown in Figure 53.
