Cisco Cisco Aironet 1530i Outdoor Access Point 릴리즈 노트

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.

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.

The point-to-point and point-to-multipoint bridging is supported on the Cisco Aironet 1040, 1140, 1260, 
1600, 2600, 3500 and 3600 series access points (802.11n platforms). The 5-GHz bands support 20 and

The following items are supported for AP1040, AP1140, AP1260, AP1600, AP2600, AP3500, and 
AP3600 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

This is only supported using short range links and is not a replacement for the AP-1300/1400 or other 
bridge products.

The following items are not supported for AP 702i, AP1040, AP1140, AP1260, AP1600, AP2600, 
AP3500 and AP3600 bridging:

The distance CLI command: long-range links over 1 km currently are not supported; therefore, the 
distance command is not supported.
