Wireless Array
Configuring the Wireless Array 299
2. Data Rate Presets: The Wireless Array can optimize your 802.11a data
rates automatically, based on range or throughput. Click Optimize Range
to optimize data rates based on range, or click Optimize Throughput to
optimize data rates based on throughput. The Restore Defaults button
will take you back to the factory default rate settings.
3. 802.11a IAP Control: Click Enable 802.11a IAPs to enable all 802.11an
IAPs for this Array, or click Disable 802.11a IAPs to disable all 802.11an
IAPs.
4. Channel Configuration: Click Auto Configure to instruct the Array to
determine the best channel allocation settings for each 802.11an IAP and
select the channel automatically, based on changes in the environment.
This is the recommended method for 802.11a channel allocation (see “RF
Spectrum Management” on page 324).
Click Factory Defaults if you wish to instruct the Array to return all IAPs
to their factory preset channels. As of release 6.3, Arrays no longer all use
the same factory preset values for channel assignments. Instead, if the
Array has been deployed for a while and already has data from the
spectrum analyzer and Xirrus Roaming Protocol about channel usage on
neighboring Arrays, it performs a quick auto channel using that
information (without doing a full RF scan) to make an intelligent choice
of channel assignments. If the Array has been rebooted and has no saved
configuration or is just being deployed for the first time, it has no prior
data about its RF environment. In this case, it will pick a set of compatible
channel assignments at random.
The following options may be selected for auto configuration:

On the XR-500 and XR-1000 Series Arrays, the Factory Defaults button
will not restore iap1 to monitor mode. You will need to restore this setting
manually. Also, you may need to set Timeshare Mode again - see “RF
Monitor” on page 321.
