Introduction
Cisco IOS Release 12.3(7)JX provides support for the lightweight access point protocol (LWAPP) for 1130AG, 1200, 1230AG, and 1240AG series access points. When you use the Cisco IOS-TO-LWAPP upgrade tool to upgrade one of these access points to this release, the access point communicates with a Cisco 2006 series wireless LAN controller or a 4400 series controller and receives a full LWAPP configuration and software image from the controller. This release also functions as a recovery image if the access point fails to receive a full image from the controller.
Note

Reverting from LWAPP Mode to Autonomous Mode
After you use the Cisco IOS-TO-LWAPP upgrade tool to load Cisco IOS release 12.3(7)JX on an access point, you can convert the access point from an LWAPP unit back to an autonomous unit by loading a Cisco IOS release that supports autonomous mode (Cisco IOS release 12.3(7)JA or earlier). If the access point is associated to a controller, you can use the controller to load the Cisco IOS release. If the access point is not associated to a controller, you can load the Cisco IOS release using TFTP.

LWAPP Upgrade and Recovery Support
This feature allows an access point to communicate with a wireless LAN controller in order to receive the LWAPP image mandated by the controller. New LWAPP access points or access points being upgraded from autonomous to LWAPP mode use the LWAPP-recovery support feature to receive their LWAPP image from the controller. This release is also used as a recovery image in case the full LWAPP image becomes corrupted. The LWAPP-recovery support feature limits access point functionality to just that which is necessary to download a complete LWAPP image; for example, the radios are disabled on access points running the LWAPP-recovery support feature.
Installation Notes
This section contains information you should keep in mind when installing access points.
Installation in Environmental Air Space
This section provides information on installing 1200 series access points in environmental air space, such as above suspended ceilings.
Cisco Aironet 1130AG 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.
Caution
Note
Power Considerations
This section describes issues you should consider before applying power to an access point.
Caution
Caution
Use Only One Power Option
You cannot provide redundant power to 1130AG and 1200 series access points with both DC power to its power port and inline power from a patch panel or powered switch to the access point's Ethernet port. If you apply power to the access point from both sources, the switch or power patch panel might shut down the port to which the access point is connected. Figure 1 shows the power configuration that can shut down the port on the patch panel or powered switch.
Figure 1 Improper Power Configuration Using Two Power Sources
Configuring Power for 1130AG Access Points
The 1130AG access point disables the radio interfaces when the unit senses that the power source to which it is connected does not provide enough power. Depending on your power source, you might need to enter the power source type in the access point configuration. Use the System Software: System Configuration page on the web-browser interface to select a power option. Figure 2 shows the System Power Settings section of the System Configuration page.
Figure 2 Power Options on the System Software: System Configuration Page
Using the AC Power Adapter
If you use the AC power adapter to provide power to the 1130AG access point, you do not need to adjust the access point configuration.
Using a Switch Capable of IEEE 802.3af Power Negotiation
If you use a switch to provide Power over Ethernet (PoE) to the 1130AG access point and the switch supports the IEEE 802.3af power negotiation standard, select Power Negotiation on the System Software: System Configuration page.
Using a Switch That Does Not Support IEEE 802.3af Power Negotiation
If you use a switch to provide Power over Ethernet (PoE) to the 1130AG access point and the switch does not support the IEEE 802.3af power negotiation standard, select Pre-Standard Compatibility on the System Software: System Configuration page.
Using a Power Injector
If you use a power injector to provide power to the 1130AG access point, select Power Injector on the System Software: System Configuration page and enter the MAC address of the switch port to which the access point is connected.
Operating 5-GHz Radio Requires Power Injector, Power Module, or Catalyst 3550-24 PWR Switch
The 1200 series power injector and the 1200 series power module support operation of the 5-GHz radio in the access point. Currently, the Catalyst 3550-24 PWR switch supports power for both the 2.4-GHz radio and the 5-GHz radio. Other switches and power patch panels might not provide enough power for the 5-GHz radio.
Access Point Requires 1200 Series Universal Power Supply and Power Injector
The 350 series universal power supply and power injector are not compatible with the 1200 series access point. If you use a power injector or a power module to provide power to a 1200 series access point, you must use a 1200 series universal power supply. If you need to use a power injector to inject power into the access point's Ethernet port, you must use a 1200 series power injector.
Antenna Installation
For instructions on the proper installation and grounding of external antennas for 1200 series access points, refer to the National Fire Protection Association's NFPA 70, National Electrical Code, Article 810, and the Canadian Standards Association's Canadian Electrical Code, Section 54.
Important Notes
This section describes important information about the access point.
Default Username and Password Are Cisco
You must enter a username and password when you log into an access point interface. The default username for administrator login is Cisco, and the default password is Cisco. Both the username and password are case sensitive.
Cisco IOS Release 12.3(7)JX Supports 2006 and 4400 Controllers Only
When you load this release on an access point, the access point can communicate with Cisco 2006 series wireless LAN controllers or 4400 series controllers only. Cisco 4100 series, Airespace 4012 series, and Airespace 4024 series controllers are not supported because lack the memory required to support access points running Cisco IOS software.
Access Points Converted to LWAPP do not Support WDS
Access points converted to LWAPP mode communicate only with Cisco wireless LAN controllers and cannot communicate with WDS devices. However, the controller provides functionality equivalent to WDS when the access point associates to it.
Access Points Converted to LWAPP Support 8 BSSIDs per Radio
Access points converted to LWAPP mode support 8 BSSIDs per radio and a total of 8 wireless LANs per access point. (Cisco 1000 series access points support 16 BSSIDs per radio and 16 wireless LANs per access point.) When a converted access point associates to a controller, only wireless LANs with IDs 1 through 8 are pushed to the access point.
Access Points Converted to LWAPP do not Support Layer 2 LWAPP
Access Points converted to LWAPP must get an IP address and discover the controller using DHCP, DNS, or IP subnet broadcast.
Access Points Converted to LWAPP Provide Read-Only Console Port
After you convert an access point to LWAPP mode, the console port provides read-only access to the unit.
