Release Notes for Cisco Aironet Access Points and Bridges for Cisco IOS Release 15.2(2)JB
OL-28357-01
Important Notes
This symptom is observed only in the Cisco 1040/1140 series access point and does not have any impact
on functionality. Ignore the “watchdog timer expired” reason after an access point has been power
cycled. You can also overwrite the reset reason to “reload” by rebooting with command operation.

Regulatory Update for Japan
This release supports the U regulatory domain for the W52 frequency set (channels 36, 40, 44, and 48)
in Japan for the Cisco Aironet 1230 series. This support was added for the Cisco Aironet 1130 series in
Cisco IOS Software Release 12.4(3G)JA, which shipped previously. Cisco access points specified for
this new domain ship with a U domain radio. Installed J domain access points are automatically upgraded
to the U domain status with this release.
