Frequency configuration errors
If a radio 1 frequency configuration error is discovered when the link is started, the status of radio
1 will show “0” as the operating frequency, and the link will not start.
For example, suppose the channel bandwidth is 10 MHz and the DL Frequency is 5170000.
If the channel bandwidth is subsequently changed to 40 MHz, the DL Frequency setting will become
If a radio 1 frequency configuration error is discovered when the link is started, the status of radio

For example, suppose the channel bandwidth is 10 MHz and the DL Frequency is 5170000.
If the channel bandwidth is subsequently changed to 40 MHz, the DL Frequency setting will become
out-of-bounds, since the lowest center frequency of a 40 MHz channel bandwidth is 5190000.

Likewise, the top banner of the Web UI will show the Radio1 Tx frequency “0.000”, also indicating
an unacceptable value.

4.6.6 Configuration of Radio 2 Frequencies
The M4-2000 is a dual radio system whereby radio 1 always performs initial link establishment,
and then initiates a second link using Radio 2. The primary node always uses the initial Radio 1
connection to communicate the frequencies to be used by Radio 2.
To configure the starting frequencies for Radio 2, it is only necessary to configure the DL and UL
Frequency values on the primary node. Once the Radio 1 link is established, the Radio 2
connection to communicate the frequencies to be used by Radio 2.
To configure the starting frequencies for Radio 2, it is only necessary to configure the DL and UL
Frequency values on the primary node. Once the Radio 1 link is established, the Radio 2
configuration is interpreted by the primary node and used to set up radio 2 link.
