NOTE: If the BH timing slave does not register with the BH timing master, ensure
that both modules are configured to the same color code in the Configuration
page of each.
22. Resume slight movements of the module
23. When the best achievable values are simultaneously displayed on the Status
page, lock the module into position.
NOTE: If any of these values is not achieved, the BH timing slave may be
operational but manifest occasional problems.

19.12 UPGRADING A BH LINK TO BH20
To replace a pair of 10-Mbps BHs with 20-Mbps BHs, you can minimize downtime by
temporarily using the 10-Mbps capability in the faster modules. However, both
interference and differences in receiver sensitivity can make alignment and link
maintenance more difficult than in the previous 10-Mbps link. The effects of these factors
are greater at greater link distances, particularly at 5 miles or more.
Especially in shorter spans, these factors may not be prohibitive. For these cases, set the
first replacement module to 10-Mbps and establish the link to the 10-Mbps BH on the far
end. Similarly, set the second replacement module to 10-Mbps and re-establish the link.
With both of the faster modules in place and with an operational link having been
achieved, reset their modulation rates to 20 Mbps.
19.13 VERIFYING A BH LINK
To verify the performance of the BH link after the BHs have been installed, perform the
following steps.
Procedure 36: Verifying performance for a BH link
1. Access the web-based interface for the BHM (by opening http://<ip-address
>,
where <ip-address> is the address of the individual module).
2. Verify that the Antenna Status field displays the value OK.
3. Access the Status Page of the BHS.
4. Verify that the BHS is still registered to the BHM.
5. Access the AP Eval Data page of the BHS.
6. Verify that the BH timing master is shown in the Sector ID field.
