Aligning antennas
This section describes how to align the antennas for Master and Slave ODUs in the PTP
topology, and Slave ODUs in the HCMP topology, using the web interface to assist with
alignment, and checking wireless performance after alignment.
Before performing this task, check that hardware installation is complete (apart from the
network connections) at both the Master and Slave sites.
Starting up the units
Use this procedure to connect one of the units to a management PC and start up both units.
Procedure:
1
Select the unit from which this process is to be controlled; either Master or Slave. This is the
“local” unit.
2
Check that the management PC is connected to the local unit, powered up and logged on as
described in
4
Power up the remote unit.
5
Log into the local unit as described in
Logging into the web interface
Checking that the units are armed
Use this procedure to confirm that the units are in the armed state, ready for alignment.
In the armed state, the modulation mode is fixed at BPSK 0.63 Single, the TDD frame duration
is extended to allow the link to acquire at unknown range, and the transmit power is
automatically adjusted for optimum operation.
Procedure:
•
Select menu option Home. The System Summary page is displayed.
•
Check that the Install Arm State is set to Armed.
•
If the units are not armed, execute the installation wizard as described in
