Introduction

Cisco Wireless LAN Controller (WLC) Field Upgrade Software (FUS) is a special AES package that performs various system-related component upgrades. We recommend that you install the FUS image to upgrade components such as the bootloader, field recovery image, FPGA/MCU, and other firmware to their latest respective versions.

Table 1 lists the components that are upgraded after you install Field Upgrade Software for various controller platforms.

Table 1 Cisco WLC Platforms and Upgraded Components

Cisco WLC Platform
Upgraded Components

Cisco 2500 Series Wireless LAN Controllers

•Field Recovery Image is upgraded from 7.0.112.21 to 7.6.101.1

•Bootloader is upgraded to 1.0.20

•Offline Field Diagnostics is upgraded from 0.9.28 to 0.9.35

Cisco 5500 Series Wireless LAN Controllers

•Field Recovery Image is upgraded from 7.0.112.21 to 7.6.101.1

•Bootloader is upgraded to 1.0.20

•Offline Field Diagnostics is upgraded from 0.9.28 to 0.9.35

•FPGA Revision version is upgraded to 1.7

•Environment Controller (MCU) Image version is upgraded to 1.8

•USB Console Revision version is upgraded to 2.2

Cisco Wireless Services Module 2 (WiSM2)

•Field Recovery Image is upgraded from 7.0.112.21 to 7.6.101.1

•Bootloader is upgraded to 1.0.20

•Offline Field Diagnostics is upgraded from 0.9.28 to 0.9.35

•USB Console Revision version is upgraded to 2.2

Note Due to a software issue, the FPGA does not get upgraded in a Cisco WiSM2 even though the console output indicates that it has been upgraded.

Cisco Flex 7500 Series Wireless LAN Controllers

RAID firmware


Guidelines and Limitations

Caution Ensure that there are no power outages during the upgrade. Power outages during the upgrade may lead to the controller not being usable.

•This release of the Field Upgrade Software is applicable to Cisco WLCs that are installed with the controller software release 6.0 and later.

•You must install the FUS image only once.

•Console access to the WLC during the upgrade process is not required. However it is recommended that you have console access so that you can monitor the progress of the process.

•The FUS upgrade process reboots the Cisco WLC several times, and reboot the default runtime image. The whole process takes approximately 30 minutes.

•After you install the FUS image for a Cisco Flex 7500 Controller platform, the RAID firmware is also upgraded. During the installation process, the console messages displayed do indicate upgrade of the RAID firmware. However, it is not possible to verify the RAID firmware upgrade either by entering a command or viewing the bootlog.

Supported Hardware

The FUS image is applicable only to the following controller platforms in this release:

–Cisco 2500 Series Wireless LAN Controller

–Cisco 5500 Series Wireless LAN Controller

–Cisco Flex 7500 Series Wireless LAN Controller

–Cisco Wireless Services Module 2 (WiSM2)

Downloading Field Upgrade Software

Step 1 Go to the Cisco Software Center at this URL: http://www.cisco.com/cisco/software/navigator.html

Step 2 Choose Products > Wireless > Wireless LAN Controller.

Step 3 Choose either of the following depending on the controller platform you use:

•Integrated Controllers and Controller Modules

•Standalone Controllers

Step 4 Choose the controller model number or name. The Download Software page is displayed.

Step 5 Choose Wireless LAN Controller Software.

Step 6 Click a controller software release. The software releases are labeled as follows to help you determine which release to download:

•Early Deployment (ED)—These software releases provide new features and new hardware platform support as well as bug fixes.

•Maintenance Deployment (MD)—These software releases provide bug fixes and ongoing software maintenance.

•Deferred (DF)—These software releases have been deferred. We recommend that you migrate to an upgraded release.

Step 7 Click a software release number. Click the filename (for example, AIR-CT5500-K9-1-9-0-0-FUS.aes). The following AES files are available for various controller platforms:

–AIR-CT5500-K9-1-9-0-0-FUS.aes

–AIR-CT5500-LDPE-1-9-0-0-FUS.aes

–AIR-CT7500-K9-1-9-0-0--FUS.aes

–AIR-WISM2-K9-1-9-0-0-FUS.aes

–AIR-CT2500-K9-1-9-0-0-FUS.aes

Step 8 Click Download.

Step 9 Read Cisco's End User Software License Agreement and then click Agree.

Step 10 Save the file to your hard drive.

Step 11 Copy the AES file (for example AIR-CT5500-K9-1-9-0-0-FUS.aes) to the default directory on your TFTP or FTP server.

Installing Field Upgrade Software (CLI)

Step 1 Enter the following commands on the Cisco WLC CLI:

a. transfer download datatype code

b. transfer download serverip serverip

c. transfer download mode {tftp | ftp}

d. transfer download username user

e. transfer download password password

f. transfer download filename filename.aes

g. transfer download path /

h. transfer download start

Step 2 Enter the following command to reboot the Cisco WLC:

reset system

Information similar to the following is displayed; this is a sample output from a Cisco Flex 7500 Series WLC:

Upgrading FUS Image

Step 1 Upload your controller configuration files to a server to back them up.

Step 2 Get the controller software image as defined in Downloading Field Upgrade Software, and follow these steps:

a. Choose Wireless > Wireless LAN Controller. The following options are available: Integrated Controllers and Controller Modules and Standalone Controllers.

b. Depending on your controller platform, click one of the above options.

c. Click the controller model number or name. The Download Software page is displayed.

d. Click a controller software release. The software releases are labeled as follows to help you determine which release to download:

–Early Deployment (ED)—These software releases provide new features, new hardware platform support, and bug fixes.

–Maintenance Deployment (MD)—These software releases provide bug fixes and ongoing software maintenance.

–Deferred (DF)—These software releases have been deferred. We recommend that you migrate to an upgraded release.

e. Choose a software release number.

f. Click the filename (for example, AIR-CT5500-K9-1-9-0-0-FUS.aes).

g. Click Download.

h. Read Cisco's End User Software License Agreement and then click Agree.

i. Save the file to your hard drive.

j. Repeat steps a through k to download the remaining file.

Step 3 Copy the controller software image (filename.aes) to the default directory on your TFTP or FTP server.

Step 4 (Optional) Disable the 802.11 networks.

Note For busy networks, controllers on high utilization, or small controller platforms, we recommend that you disable the 802.11 networks as a precautionary measure.

Step 5 Disable any WLANs on the controller.

Step 6 Choose Commands > Download File to open the Download File to Controller page.

Step 7 From the File Type drop-down list, choose Code.

Step 8 From the Transfer Mode drop-down list, choose from the following options:

•TFTP

•FTP

Step 9 In the IP Address text box, enter the IP address of the server.

If you are using a TFTP server, the default values of 10 retries and 6 seconds for the Maximum Retries and Timeout text boxes should work correctly without any adjustment. However, you can change these values.

Step 10 If you are using a TFTP server, the default values of 10 retries for the Maximum Retries text field, and 6 seconds for the Timeout text field should work correctly without any adjustment. However, you can change these values if desired. To do so, enter the maximum number of times that the TFTP server attempts to download the software in the Maximum Retries text box and the amount of time (in seconds) that the TFTP server attempts to download the software in the Timeout text box.

Step 11 In the File Path text box, enter the directory path of the software.

Step 12 In the File Name text box, enter the name of the controller software file (for example, AIR-CT5500-K9-1-9-0-0-FUS.aes).

Step 13 If you are using an FTP server, follow these steps:

•In the Server Login Username text box, enter the username to log into the FTP server.

Step 15 After the download is complete, click Reboot.

Step 16 If prompted to save your changes, click Save and Reboot.

Step 17 Click OK to confirm.

Step 18 After the controller reboots, repeat step 6 to step 17 to install the remaining file.

Step 19 Reenable the WLANs.

Step 20 For Cisco WiSM2, reenable the controller port channel on the Catalyst switch.

Step 21 If you have disabled the 802.11 networks in Step 4, reenable them.

Step 22 To verify the controller software version, choose Monitor on the controller GUI and see Software Version in the Controller Summary area.
