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.
The channels that are available for assignment to an IAP will differ,
depending on the country of operation. If Country is set to United States
in the Global Settings (IAP) window, then 21 channels are available to
802.11an radios.
4. The Bond column 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 39.
• Channel number — If a channel number appears, then this channel is
already bonded to the listed channel.
• Off — Do not bond his channel to another channel.
• On — Bond this channel to an adjacent channel. The bonded channel
is selected automatically by the Array based on the Channel (Step 3).
The choice of banded channel is static — fixed once the selection is
made.

As mandated by FCC/IC law, Arrays continually scan for signatures of
radar. If such a signature is detected, the Array will switch operation from
conflicting 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 off
because there were no available channels not affected 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/IC regulations.
