Firmware
The WAP device maintains two firmware images. One image is active and the other is inactive. If the active image fails to load during boot up, the inactive image is loaded and becomes the active image. You can also swap the active and inactive images.
When new versions of the firmware become available, you can upgrade the firmware on your WAP device to take advantage of new features and enhancements. The WAP device uses a TFTP or HTTP/HTTPS client for firmware upgrades.
After you upload the new firmware and the system reboots, the newly added firmware becomes the primary image. If the upgrade fails, the original firmware remains as the primary image.
Note |
When you upgrade the firmware, the WAP device retains the existing configuration settings. |
Swapping the Firmware Image
To swap the firmware image running on the WAP device:
Procedure
Step 1 |
Select Administration > Firmware. The product ID (PID VID), active and inactive firmware version are displayed. |
Step 2 |
Click Swap Images. A dialog box appears confirming the firmware image switch and subsequent reboot. |
Step 3 |
Click Yes to proceed. The process may take several minutes, during which time the WAP device is unavailable. Do not power down the WAP device while the image switch is in process. When the image switch is complete, the WAP device restarts. The WAP device resumes normal operation with the same configuration settings it had before the upgrade. |
HTTP/HTTPS Upgrade
To upgrade using HTTP/HTTPS:
Procedure
Step 1 |
Select HTTP/HTTPS as the transfer method. |
Step 2 |
Click Browse and locate the firmware image file on your network. The firmware upgrade file supplied must be a tar file. Do not attempt to use bin files or files of other formats for the upgrade; these types of files do not work. |
Step 3 |
Click Upgrade to apply the new firmware image. Uploading the new firmware may take several minutes. Do not refresh the page or navigate to another page while uploading the new firmware, or the firmware upload is aborted. When the process is complete, the WAP device restarts and resumes normal operation. |
Step 4 |
To verify that the firmware was upgraded successfully, log into the web-based Configuration Utility, open the Upgrade Firmware page, and view the active firmware version. |
TFTP Upgrade
To upgrade the firmware on the WAP device using TFTP:
Procedure
Step 1 |
Select TFTP as the transfer method. |
Step 2 |
Enter a name (1 to 256 characters) for the image file in the Source File Name field, including the path to the directory that contains the image to upload. For example, to upload the ap_upgrade.tar image located in the /share/builds/ap directory, enter: /share/builds/ap/ap_upgrade.tar The firmware upgrade file supplied must be a tar file. Do not attempt to use bin files or files of other formats for the upgrade; these types of files do not work. The filename cannot contain the following items: spaces, <, >, |, \, : , (, ), &, ; , #, ? , *, and two or more successive periods. |
Step 3 |
Enter the TFTP Server IPv4 Address and click Upgrade. Uploading the new firmware may take several minutes. Do not refresh the page or navigate to another page while uploading the new firmware, or the firmware upload is aborted. When the process is complete, the WAP device restarts and resumes normal operation. |
Step 4 |
To verify that the firmware upgrade completed successfully, log into the configuration utility, open the Upgrade Firmware page, and view the active firmware version. |
