When using Link
Test with MIR,
need to set both
ends
To see the effects of MIR capping, you can run a link test with MIR enabled.
To get meaningful results, set Link Test with MIR to Enabled on the
Tools => Link Capacity Test tab in both the SM and the AP. When it is
enabled on only one end, results are misleading.
After you run perform a link test with MIR capping enabled, consider
immediately changing Link Test with MIR to Disabled in both the SM and
the AP, to avoid mistakenly capping only one end of the link test.

Click Spectrum
Analyzer Enable
button twice
After you click the Enable button in the Tools => Spectrum Analyzer tab, the
resulting display may omit bars for some frequencies, especially in
frequency bands that have a large number of center channels, such as
the 5.4-GHz band. If you clicking Enable again, the display includes the
entire spectrum bar graph.
TIP: In the Configuration => General tab, set the Webpage Auto Update
parameter to a few seconds, to have the Spectrum Analyzer automatically
fully displayed and refreshed. You can later reset the Webpage Auto
Update time back to 0, to disable refresh.

Session Status

In some instances, depending on network activity and network design, the
interface presents a blank screen to a user who logs in to an SM through the

browser window.

5590 through
5660 may
interfere with
weather radar, not
allowed in Europe,
Canada, and
Australia
Canopy center channel frequencies of 5590 MHz through 5660 MHz may
interfere with, or be interfered by, weather radar in several Regions,
including Europe, the US, Canada, and Australia. In Europe, Canada, and
Australia, to be in regulatory compliance, operators must not transmit on
these frequencies. Setting the Region Code to Europe, Canada or
Australia notches out these frequencies and ensures compliance.
Operators who perform a site survey in the United States should use the
built-in Spectrum Analyzer or a stand-alone spectrum analyzer to check for
activity on these channels and select other channels as appropriate.

When connecting
to a hub, use only
half duplex
Ethernet settings
Ethernet connections set to 10 Base T Full Duplex or
100 Base T Full Duplex will not connect to an SM through a hub, due to the
way a hub works. Use half duplex settings when using a hub.
5.2 OPERATION BASED ON REGION CODE AND FREQUENCY BAND
There are no changes to Region Code operation in Release 9.4.2. For reference, Table 8 shows
operation based on Region Code, by frequency band and module type.
