Procedure for Manually Configuring IAPs

1. In the Enabled column, check the box for a corresponding IAP to enable

the IAP, or uncheck the box if you want to disable the IAP.

2. In the Band column for 802.11abg(n) radios, select the wireless band for

this IAP from the choices available in the pull-down menu, either 2.4GHz

or 5 GHz. If the mode displayed is Auto, the mode has been set by the

auto-channel feature based on the Channel selected. Note that IAP

abg(n)2 has an additional option—monitor mode. IAP abg(n)2 should

normally be set to monitor mode to enable Spectrum Analyzer and Radio

Assurance (loopback testing) features.

3. In the Channel column, select the channel you want this IAP to use from

the channels available in the pull-down list. The list shows the channels

available for the IAP selected (depending on which band the IAP is

using). Channels that are shown in color indicate conditions that you

need to keep in mind:

• RED—Usage is not recommended, for example, because of overlap

with neighboring radios.

• YELLOW—The channel has less than optimum separation (some

degree of overlap with neighboring radios).

• GRAY—The channel is already in use.

Select Auto to have the Array dynamically select a channel automatically,

based on changes in the Wi-Fi environment. See “Allocating Channels”

on page 54. After you click Apply, this window and the IAPs window

will show the channel that was assigned, rather than Auto.

The XN16, XS16, and XS-3900 allow up to 12 IAPs to operate as 5 GHz —

802.11a(n) radios concurrently. Do not set Mode to 5 GHz for more than 12

IAPs. If you need additional 5 GHz radios, please contact Xirrus Customer

Support. See “Contact Information” on page 417.
