Cisco Cisco Aironet 1200 Access Point 릴리즈 노트

The following are special notes about Cisco IOS Release 12.3(11)JX upgrade and recovery software 
image:

Autonomous access points that have already been upgraded to lightweight mode may update to the 
12.3(11)JX image using the standard upgrade procedure.

Use the Autonomous To Lightweight Mode upgrade tool to load this image onto Cisco Aironet 
autonomous access points currently running Cisco IOS Release 12.3(11)JA or later.

This release only contains a partial LWAPP image. The full LWAPP software image must be 
downloaded from the Cisco Wireless LAN Controller to the access point after it has been converted 
in order for it to operate as a Cisco Aironet lightweight access point. A connection between the 
access point and Cisco Wireless LAN Controller is required to download the full LWAPP image.

This image is also shipping with orderable Cisco Aironet lightweight access points.

This section contains information you should keep in mind when installing 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, 1130, 1200, and 1240 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 35 to 57 VDC, and the nominal voltage is 
48 VDC. Voltage higher than 60 VDC can damage the equipment.
