Upgrading Controller Software
Mandatory Boot Variable Update for Networks with 1522 Access Points
If your network is operating with 1520 series access points or you plan to install 1522 access points in
your network, you must set the boot variable on the access point before upgrading from software release
4.1.190.5 to 4.1.192.35M or installing a 1520 series access point in a 4.1.192.35M or 5.2 or later
network. Updating the boot variable ensures that the 1522 access point joins correctly.
Note
You should check the boot variable setting before updating the boot.
•
If the boot system image is visible, then no boot variable update is required.
–
If upgrading from software release 4.1.190.5, the system image should read:
flash:/c1520-k9w9-mx.124-3g.JMA1/c1520-k9w9-mx.124-3g.JMA1
•
If the boot system image is missing, then you must update the boot variable.
Checking the Boot Variable Setting
Follow these steps to check the setting of the boot variable.
Step 1
On the controller CLI, enter these commands for each mesh access point:
debug ap enable
ap_name
debug ap command "more flash:/env_vars"
