• 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 67. After you click Apply , this window and the IAPs window
will show the channel that wa s assigned, rather than Auto.
The channels that are available for assignment to an IAP will dier,
depending on the country of operation. If Country is set to United States
in the Global Settings (IAP) window, then 24 channels are available to
802.11a(n) radios.
4. The Bond column only appears for XR and XN Array models. It works
together with the channel bonding options selected on the Global Settings
.11n page. Also see the discussion of 802.11n bonding in “Channel
Bonding” on page 76 .

As mandated by FCC law, Arrays continually scan for signatures of military
radar. If such a signature is detected, the Array will switch operation from
conicting channels to new ones. The Array will switch back to the original
channel after 30 minutes if the channel is clear. If a radio was turned o
because there were no available channels not aected by radar, the Array will
now bring that radio back up after 30 minutes if that channel is clear. The 30
minute time frame complies with FCC reg
ulations.
