Section 7 - Maintaining the Access Point

As new versions of the UAP rmware become available, you can upgrade the rmware on your devices to take

advantage of new features and enhancements. The AP uses a TFTP client for rmware upgrades. You can also use

HTTP to perform rmware upgrades.

After you upload new rmware and the system reboots, the newly added rmware becomes the primary image. If the

upgrade fails, the original rmware remains as the primary image.

Note: When you upgrade the rmware, the access point retains the existing conguration

information.

Use the following steps to upgrade the rmware on an access point by using TFTP:

1.) Select TFTP for Upload Method.

Figure 55 - Manage Firmware (TFTP)

2.) Enter a name (1 to 255 characters) for the image le in the Image Filename eld, 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

in the Image Filename eld.

The rmware upgrade le supplied must be a tar le. Do not attempt to use bin les or les of other formats for

the upgrade; these types of les will not work.

3.) Enter the Server IP address of the TFTP server.

4.) Click Upgrade.

Upon clicking Upgrade for the rmware upgrade, a popup conrmation window is displayed that describes the

upgrade process.

5.) Click OK to conrm the upgrade and start the process.

Note: The rmware upgrade process begins once you click Upgrade and then OK in the pop-up

conrmation window.

The upgrade process may take several minutes during which time the access point will be unavailable. Do not

power down the access point while the upgrade is in process. When the upgrade is complete, the access point

restarts. The AP resumes normal operation with the same conguration settings it had before the upgrade.

6.) To verify that the rmware upgrade completed successfully, check the rmware version shown on the Upgrade

page (or the Basic Settings page). If the upgrade was successful, the updated version name or number is

indicated.

Use the following steps to upgrade the rmware on an access point by using HTTP:

1.) Select HTTP for Upload Method.

Figure 56 - Manage Firmware (HTTP)

2.) If you know the path to the new rmware image le, enter it in the Image Filename eld. Otherwise, click the

Browse button and locate the rmware image le.

The rmware upgrade le supplied must be a tar le. Do not attempt to use bin les or les of other formats for

the upgrade; these types of les will not work.
