Cisco Cisco Industrial Wireless 3702 Access Point

This section describes important information about access points and bridges.

Install only Cisco IOS Release 15.3(3)JA1 and newer releases on Cisco Aironet Universal Access Point 
models. Do not install older Cisco IOS releases on Cisco Aironet Universal Access Point models as that 
is a violation of local radio regulations and laws. 

This 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 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.

For more information, see caveat CSCtc22803.

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.
