Примечания к выпуску для Cisco Cisco 2106 Wireless LAN Controller

If any part of an antenna system should come in contact with a power line, do not touch it or try 
to remove it yourself. Call your local power company. They will remove it safely.

If an accident should occur with the power lines, call for qualified emergency help immediately.

Refer to the appropriate quick start guide or hardware installation guide for instructions on installing 
controllers and access points.

To meet regulatory restrictions, all external antenna configurations must be professionally installed.

Personnel installing the controllers and access points must understand wireless techniques and 
grounding methods. Access points with internal antennas can be installed by an experienced IT 
professional.

The controller must be installed by a network administrator or qualified IT professional, and the proper 
country code must be selected. Following installation, access to the controller should be password 
protected by the installer to maintain compliance with regulatory requirements and ensure proper unit 
functionality.

This section describes new features and operational notes about the controllers and access points.

When a mesh access point (MAP) detects radar in a sector, that information is forwarded to all mesh 
access points within that sector; and all MAPs and RAPs belonging to that sector will move to the new 
channel. This functionality lowers the probability of MAP strandings.

To enable this functionality in a mesh network, enter the following CLI command:

config mesh full-sector-dfs enable

To prevent the RAP from moving its sector back to the previously configured channel, enter the 
following command:

config advanced 802.11a channel delete channel-number

To disable this functionality in a mesh network, enter the following CLI command:

config mesh full-sector-dfs disable
