3. Reboot the BH.
RESULT: The set of interface web pages that is unique to a BHM is made available.
Link Speed
From the drop-down list of options, select the type of link speed for the Ethernet connection. The
default for this parameter is that all speeds are selected. The recommended setting is a single speed
selection for all APs, BHs, and SMs in the operator network.
Sync Input
Specify the type of synchronization for this BH timing master to use.
Select Sync to Received Signal (Power Port) to set this BHM to receive sync from a
connected CMMmicro or CMM4.
Select Sync to Received Signal (Timing Port) to set this BHM to receive sync from a
connected CMM2, an AP in the cluster, an SM, or a BH timing slave.
Select Generate Sync Signal where the BHM does not receive sync, and no AP or other
BHM is active within the link range.
Verify GPS Message Checksum
When enabled (Sync Input “Sync to Received Signal (Timing Port)” must be selected for this
parameter to display), the device validates GPS messaging to ensure that the radio is properly
receiving data from the GPS source. If a GPS source is not calculating and sending checksum
data properly, the BHM will still receive synchronization pulses but not GPS data (location, data,
etc.) and the Invalid Message counter will increase on the radio’s Home > GPS Status page. If an
BHM is receiving synchronization properly from a GPS unit but is not receiving GPS data,
operators may set Verify GPS Message Checksum to “Disabled” to ignore checksum failures and
to allow the BHM to process the GPS data.
Region Code
From the drop-down list, select the region in which the radio is operating.
When the appropriate region is selected in this parameter, the radio automatically implements the
applicable required Dynamic Frequency Selection (DFS) standard. For further information on
DFS, see Radar Signature Detection and Shutdown on Page 127.
Unlike selections in other parameters, your Region Code selection requires a Save Changes and a
Reboot cycle before it will force the context-sensitive GUI to display related options (for
example, Alternate Frequency Carrier 1 and 2 in the Configuration => Radio tab). Thus, a
proper configuration exercise in environments that are subject to DFS requirements has two
imperative Save Changes and Reboot cycles: one after the Region Code is set, and a second after
related options are set.
