Cisco 1040/1140 Series Access Points May Record "watchdog timer expired" as
Last Reset Reason
The following error message sometimes appears as the last reset reason when the access points are power
cycled:
Watchdog timer expired
This symptom is observed only in 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 1200 and 1230 Series. This support was added for the Cisco Aironet 1130
and 1240 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 U domain status with this release.
