Wi-Fi Array
Using Tools on the Wi-Fi Array 327
3. License Key: If Xirrus provides you with a new license key for your
Array, use this field to enter it, then click the Upgrade button to the right.
A valid license is required for Array operation, and it controls the features
available on the Array. If you upgrade your Array for additional features,
you will be provided with a license key to activate those capabilities.
If you attempt to enter an invalid key, you will receive an error message
and the current key will not be replaced.
Automatic Updates from Remote Image or Configuration File
The Array software image or configuration file can be downloaded from an
external server. In large deployments, all Arrays can be pointed to one TFTP
server instead of explicitly initiating software image uploads to all Arrays. When
the Array boots, the Array will download the software image from the specified
TFTP server. Similarly, if you decide to change a setting in the Arrays, you can
simply modify a single configuration file. After the Arrays are rebooted, they will
automatically download the new configuration file from a single location on the
specified TFTP server.
4. Remote TFTP Server: This field defines the path to a TFTP server to be
used for automated remote update of software image and configuration
files when rebooting. You may specify the server using an IP address or
host name. Click Save when done.
5. Remote Boot Image: When the Array boots up, it fetches the software
image file specified here from the TFTP server defined above, and
upgrades to this image before booting. This must be an Array image file
with a .bin extension. Click Save when done.
Make sure to place the file on the TFTP server. If you disable the remote
boot image (by blanking out this field) or if the image can't be transferred,
the Array will fall back to booting whatever image is on the compact
flash.
