Rebooting the <strong>Access</strong> <strong>Point</strong><br />

7 Maintaining the <strong>Access</strong> <strong>Point</strong><br />

For maintenance purposes or as a troubleshooting measure, you can reboot the <strong>Unified</strong> <strong>Access</strong><br />

<strong>Point</strong>. To reboot the access point, click the Reboot button on the Configuration page.<br />

Upgrading the Firmware<br />

As new versions of the DWL-3500<strong>AP</strong> and DWL-8500<strong>AP</strong> firmware become available, you can<br />

upgrade the firmware on your devices to take advantages of new features and enhancements.<br />

The <strong>AP</strong> uses a TFTP client for firmware upgrades. You can also use HTTP to perform<br />

firmware upgrades.<br />

NOTE: When you upgrade the firmware, the access point retains the existing<br />

configuration information.<br />

Use the following steps to upgrade the firmware on an access point by using TFTP:<br />

1. Click the Upgrade tab in the Maintenance section.<br />

Information about the current firmware version is displayed and an option to upgrade a<br />

new firmware image is provided.<br />

2. Make sure the Use TFTP to upload the file option is selected.<br />

3. Enter a name for the image file in the New Firmware Image field, including the .tar file<br />

name extension.<br />

The firmware upgrade file supplied must be in the format .upgrade.tar. Do<br />

not attempt to use .bin files or files of other formats for the upgrade; these<br />

types of files will not work.<br />

4. Enter the IP address of the TFTP server, including the path to the directory, that contains<br />

the image to upload.<br />

5. Click Upgrade.<br />

Upon clicking Upgrade for the firmware upgrade, a popup confirmation window is<br />

displayed that describes the upgrade process.<br />

6. Click OK to confirm the upgrade and start the process.<br />
