Cisco Cisco Aironet 1040 Series Access Point Notas de publicación

This section describes important information about access points and bridges.

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 after power cycled. You can also overwrite the reset 
reason to"reload" by rebooting with command operation.

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.

The following items are supported for AP1040 and AP1260 bridging:

MIMO antennas (line of sight and short range) under 1 Km.

20-MHz and 40-MHz 802.11n support.

Workgroup bridge (WGB) short-range support.

SISO (single-in, single-out), MCS 0-7 and legacy bridge rates (802.11 a/b/g and 802.11n) using one
