System Overview Tsunami MP.11 5012-SUR Installation and Management

Basic Configuration Information

To view or change basic system information, click the Configure button on the left side of the Web interface window, then

click the System tab. See System Parameters for detailed information about the fields and selections in this window.

NOTE: System Name by default contains the actual model number. The following screenshot is for information only.

Country and Related Settings

The unit’s Configure System window provides a selectable Country field that automatically provides the allowed

bandwidth and frequencies for the selected country.

Units sold in the United States are pre-configured to scan and display only the outdoor frequencies permitted by the FCC.

No other Country can be configured. Units sold outside of the United States support the selection of a Country by the

professional installer.

NOTE: Non-US installers should not add an antenna system until the Country is selected, the unit is rebooted, and the

proper power level is configured. The output power level of the final channel selected by DFS scan can be found

in the Event Log.

The Dynamic Frequency Selection (DFS) feature is enabled automatically when you choose a country with a regulatory

domain that requires it. The Transmit Power Control (TPC) feature is always available.

Click the Configure > System; then select the appropriate country for your regulatory domain from the Country drop-

down box.

Continue configuring settings as desired; then click Commands > Reboot and click on the Reboot button to save and

activate the settings. Alternatively, if you want to save the configuration settings to the flash memory but not activate the

settings, use the save config CLI command.

Dynamic Frequency Selection (DFS)

The Tsunami MP.11 5012-SUR supports Dynamic Frequency Selection (DFS) for European Telecommunications

Standard Institute (ETSI) domains per EN 301-893 regulations. The ETSI requires that 802.11a devices use DFS to

prevent interference with radar systems and other devices that already occupy the 5 GHz band.

During boot-up, the unit scans the available frequency and selects a channel that is quiet and free of radar interference. If

the unit subsequently detects radar interference on its channel, it rescans to find a better channel. Upon finding a new

channel, the unit waits 60 seconds to detect radar interference; if it finds no interference, it switches to the new channel.

If you are using a 5012-SUR unit in Europe or other applicable countries, keep in mind the following:
