Cisco Cisco Aironet 1200 Access Point 릴리즈 노트

This feature allows an access point to segregate WLAN clients into different mobility groups. Once a 
client is authenticated using its mobility group's security policy, all IP traffic from the client is 
encapsulated using Generic Routing Encapsulation (GRE) and sent to a specific multipoint generic 
routing encapsulation (mGRE) interface of a Cisco Structured Wireless-Aware Network (SWAN) 
infrastructure device that supports mobility groups. A Layer 3 mobility service capable access point 
provides clients within each mobility group with Layer 3 mobility when used with a Cisco SWAN 
infrastructure device supporting Layer 3 mobility. Support for Layer 3 roaming is provided for all Wi-Fi 
Certified client devices. Support for fast secure Layer 3 roaming is provided for Cisco or Cisco 
Compatible wireless client devices using the Cisco Centralized Key Management (CCKM) protocol. 

This section contains information you should keep in mind when installing 350, 1100, and 1200 series 
access points.

This section provides information on installing 1100 and 1200 series access points in environmental air 
space, such as above suspended ceilings.

Cisco Aironet 1100 and 1200 Series Access Points provide adequate fire resistance and low 
smoke-producing characteristics suitable for operation in a building's environmental air space, such as 
above suspended ceilings, in accordance with Section 300-22(C) of the National Electrical Code (NEC) 
and Sections 2-128, 12-010(3) and 12-100 of the Canadian Electrical Code, Part 1, C22.1.

The power injector does not provide fire resistance and low smoke-producing characteristics and is not 
intended for use in extremely high or low temperatures or in environmental air spaces, such as above 
suspended ceilings.

If you plan to mount a 1200 series access point with a 5-GHz radio in an area subject to environmental 
air space, Cisco recommends that you mount the access point horizontally so that its antennas point 
down. Doing so ensures that the access point complies with regulatory requirements for environmental 
air space with the 5-GHz radio installed. 

This section describes issues you should consider before applying power to an access point.

The operational voltage range for 1100 series access points is 24 to 60 VDC, and the nominal voltage is 
48 VDC. Voltage higher than 60 VDC can damage the equipment.
