About Licensing and Upgrades
The Array’s license determines many of the features
that are available on the
Array. For example, automatic cell sizing and channel allocation require a license
that includes the Xirrus Advanced RF Performance Manager (RPM). Also, IEEE
802.11n operation on XN model Arrays is a licensed feature. To check the features
supported by your license, see “Array Information” on page 101.
If you are upgrading the Array to add new features that are not supported by
your existing license, you must enter the new license key that includes the
upgrade’s features before upgrading.
Similarly, if you are upgrading the Array for a new release, you must enter the
new license key that enables the operation of that release before upgrading. If you
do not enter the new license first, the Array will display a message and revert to
the previous software image, rather than trying to run new software for which it
is not licensed. Major releases will need a new license key, but minor releases will
not. For example, to upgrade from ArrayOS Release 5.0.5 to Release 5.1, you must
enter a new license key. To upgrade from ArrayOS Release 5.0.5 to Release 5.0.6,
use your existing license key.
If you will be entering license keys and performing upgrades on many Arrays, the
effort will be streamlined by using the Xirrus Management System (XMS).
Procedure for Configuring System Tools
These tools are broken down into the following sections:
 System
 Configuration
 Diagnostics
 Web Page Redirect

Some tools, such as Network Tools and Diagnostics, are only available if the
Array’s license includes the Xirrus Advanced RF Analysis Manager
(RAM). If a tool is unavailable (grayed out), then your license does not
support the feature. See “About Licensing and Upgrades” on page 361.
