Note If you downgrade from a Cisco WLC release that supports new mobility to a Cisco WLC release that does not support new mobility (for example, Release 7.6 to Release 7.3.x) and you download the 7.6 configuration file with new mobility in enabled state, the release that does not support new mobility will have the new mobility feature in enabled state.
Note The FUS image installation process reboots the Cisco WLC several times and reboots the runtime image. The entire process takes approximately 30 minutes. We recommend that you install the FUS image in a planned outage window.
Note If you are using a Cisco 2500 Series controller and you intend to use the Application Visibility and Control (AVC) and NetFlow protocol features, you must install Release 1.9.0.0 of Cisco Wireless LAN Controller Field Upgrade Software (FUS). This is not required if you are using other controller hardware models.
Note Bootloader upgrade is not required if FIPS is disabled.
For the Cisco WLAN Express Setup for Cisco 2500 Series Wireless Controller feature, we recommend the following browsers:
– Microsoft Internet Explorer 10 or a later version
– Mozilla Firefox 26 or a later version
– Apple Safari 6 or a later version
– Ensure that your TFTP server supports files that are larger than the size of Cisco WLC software Release 7.6.130.0. Some TFTP servers that support files of this size are tftpd32 and the TFTP server within the Prime Infrastructure. If you attempt to download the 7.6.130.0 Cisco WLC software and your TFTP server does not support files of this size, the following error message appears:
“TFTP failure while storing in flash.”
– If you are upgrading through the distribution system network port, the TFTP or FTP server can be on the same subnet or a different subnet because the distribution system port is routable.

This section contains important information to keep in mind when installing Cisco WLCs and access points.
Warning This warning means danger. You are in a situation that could cause bodily injury. Before you work on any equipment, be aware of the hazards involved with electrical circuitry and be familiar with standard practices for preventing accidents. Use the statement number provided at the end of each warning to locate its translation in the translated safety warnings that accompanied this device. Statement 1071
Warning Only trained and qualified personnel should be allowed to install, replace, or service this equipment. Statement 1030
Warning Do not locate the antenna near overhead power lines or other electric light or power circuits, or where it can come into contact with such circuits. When installing the antenna, take extreme care not to come into contact with such circuits, as they may cause serious injury or death. For proper installation and grounding of the antenna, please refer to national and local codes (e.g. U.S.: NFPA 70, National Electrical Code, Article 810, Canada: Canadian Electrical Code, Section 54). Statement 280
Warning This product relies on the building’s installation for short-circuit (overcurrent) protection. Ensure that a fuse or circuit breaker no larger than 120 VAC, 15A U.S. (240 VAC, 10A international) is used on the phase conductors (all current-carrying conductors). Statement 13
Warning This equipment must be grounded. Never defeat the ground conductor or operate the equipment in the absence of a suitably installed ground connector. Contact the appropriate electrical inspection authority or an electrician if you are uncertain that suitable grounding is available. Statement 1024
Warning Read the installation instructions before you connect the system to its power source. Statement 10
Warning Do not work on the system or connect or disconnect any cables (Ethernet, cable, or power) during periods of lightning activity. The possibility of serious physical injury exists if lightning should strike and travel through those cables. In addition, the equipment could be damaged by the higher levels of static electricity present in the atmosphere. Statement 276
Warning Do not operate the unit near unshielded blasting caps or in an explosive environment unless the device has been modified to be especially qualified for such use. Statement 364
Warning In order to comply with radio frequency (RF) exposure limits, the antennas for this product should be positioned no less than 6.56 ft. (2 m) from your body or nearby persons. Statement 339
Warning This unit is intended for installation in restricted access areas. A restricted access area can be accessed only through the use of a special tool, lock and key, or other means of security. Statement 1017
Follow the guidelines in this section to ensure proper operation and safe use of the Cisco WLCs and access points.
FCC Compliance with its action in ET Docket 96-8, has adopted a safety standard for human exposure to RF electromagnetic energy emitted by FCC-certified equipment. When used with approved Cisco Aironet antennas, Cisco Aironet products meet the uncontrolled environmental limits found in OET-65 and ANSI C95.1, 1991. Proper operation of this radio device according to the instructions in this publication results in user exposure substantially below the FCC recommended limits.
For your safety, and to help you achieve a good installation, read and follow these safety precautions. They might save your life!
1. If you are installing an antenna for the first time, for your own safety as well as others, seek professional assistance. Your Cisco sales representative can explain which mounting method to use for the size and type of antenna you are about to install.
2. Select your installation site with safety as well as performance in mind. Electric power lines and phone lines look alike. For your safety, assume that any overhead line can kill you.
3. Call your electric power company. Tell them your plans and ask them to come look at your proposed installation. This is a small inconvenience considering your life is at stake.
4. Plan your installation carefully and completely before you begin. Successfully raising a mast or tower is largely a matter of coordination. Each person should be assigned to a specific task and should know what to do and when to do it. One person should be in charge of the operation to issue instructions and watch for signs of trouble.
5. When installing an antenna, remember:
b. Do not work on a wet or windy day.
c. Do dress properly—shoes with rubber soles and heels, rubber gloves, long-sleeved shirt or jacket.
6. If the assembly starts to drop, get away from it and let it fall. Remember that the antenna, mast, cable, and metal guy wires are all excellent conductors of electrical current. Even the slightest touch of any of these parts to a power line completes an electrical path through the antenna and the installer: you!
7. 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.
8. If an accident should occur with the power lines, call for qualified emergency help immediately.
See the appropriate quick start guide or hardware installation guide for instructions on installing Cisco WLCs and access points.
Note To meet regulatory restrictions, all external antenna configurations must be installed by experts.
Personnel installing the Cisco WLCs and access points must understand wireless techniques and grounding methods. Access points with internal antennas can be installed by an experienced IT professional.
The Cisco WLC must be installed by a network administrator or qualified IT professional, and the proper country code must be selected. Following installation, access to the Cisco WLC should be password protected by the installer to maintain compliance with regulatory requirements and ensure proper unit functionality.
