Cisco Cisco Wireless Services Module 2 (WiSM2) Notas de publicación

When upgrading from Release 7.3.x to Release 7.5.102.0, the primary controller gets upgraded 
while the secondary controller does not get upgraded because of an error of application timeout 
while transferring the image from the primary controller to the secondary controller. This causes the 
controllers to go to maintenance mode when rebooting after upgrade because of image mismatch.

This issue occurs when HA is enabled and when you try to upgrade from Release 7.3.x to Release 
7.5.102.0.

The workaround is as follows:

Unpair the HA controllers.

Upgrade the individual controllers to Release 7.5.102.0.

Pair up the controllers after they are upgraded.

This issue will not occur in future releases as the new images have the bug fixes and design changes, 
which will avoid this issue.

Controller using Release 7.3.112.0, configured for new mobility, might revert to old mobility after 
upgrading to Release 7.5, even though Release 7.5 supports new mobility. This issue occurs when 
new mobility, which is compatible with Cisco 5760 Wireless LAN Controller and Cisco Catalyst 
3850 Series Switch, is in use. Old mobility is not affected.

The workaround is as follows:

Enter the following commands:

config boot backup

These access points are supported in the separate 4.1.19x.x mesh software release or with

The access point must always be connected to the POE-IN port to 

associate with the controllers. The POE-OUT port is for 
connecting external devices only.
