Chapter 6: Configuration and alignment Aligning antennas Aligning antennas This section describes how to align the antennas in a PTP 650 link, use the web interface to assist with alignment, and check 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.
Chapter 6: Configuration and alignment Aligning antennas Aligning antennas Use this procedure to align linked antennas (master and slave), whether integrated or connectorized. The goal of antenna alignment is to find the center of the main beam. This is done by adjusting the antennas while monitoring the receive signal level. Preparation: Ensure that the following parameters are available: • Location of both sites (latitude and longitude). • Bearing to the other end of the link for both sites.
Chapter 6: Configuration and alignment 5 Aligning antennas When the antennas have been aligned on the center of the beam, verify that the receive level is within the predicted range (from the installation report). If this is not the case, go back to step 2. The current value of receive level can be verified by using the graphical installation method (see Graphical Install page on page 6-92) or by selecting menu option Status and monitoring the Receive Power attribute on the System Status page.
Chapter 6: Configuration and alignment Aligning antennas ODU installation tones This is the first of two methods that may be used to monitor receive signal level during antenna alignment. The ODU emits audible tones during installation to assist with alignment. The pitch of the alignment tone is proportional to the received power of the wireless signals. Adjust the alignment of the unit in both azimuth and elevation until the highest pitch tone is achieved.
Chapter 6: Configuration and alignment Aligning antennas During alignment, the installation tones should exhibit the following behavior: • Band scan: When first started up and from time to time, the Master unit will carry out a band scan to determine which channels are not in use. During this time, between 10 and 15 seconds, the Master unit will not transmit and as a consequence of this neither will the Slave unit.
Chapter 6: Configuration and alignment Aligning antennas Graphical Install page Menu option: Installation > Graphical Install (Figure 106). This is the second of two methods that may be used to monitor receive signal level during antenna alignment. Figure 106 Graphical Install page Procedure: • Check that Wireless Link Status (top left) is “Up”, “Registering”, “Searching” or “Acquiring”. • While slowly sweeping the antenna, monitor the trace of receive power over the last three minutes.
Chapter 6: Configuration and alignment Aligning antennas Disarming the units When antenna alignment is complete, use this procedure to disarm both units in the link in order to: • Turn off the audible alignment aid. • Enable adaptive modulation. • Fully enable spectrum management features (such as DSO, if configured). • Clear unwanted installation information from the various systems statistics. • Store the link range for fast link acquisition on link drop. • Enable higher data rates.
Chapter 6: Configuration and alignment Aligning antennas Comparing actual to predicted performance For at least one hour of operation after disarming, use this procedure to monitor the link to check that it is achieving predicted levels of performance. PTP LINKPlanner provides the prediction in the form of an installation report. Procedure: • Select menu option System > Statistics. The System Statistic page is displayed (Figure 108).

Chapter 8: Troubleshooting This chapter contains procedures for identifying and correcting faults in a PTP 650 link. These procedures can be performed either on a newly installed link, or on an operational link if communication is lost, or after a lightning strike. The following topics are described in this chapter: • Testing link end hardware on page 8-2 describes how to test the link end hardware, either when it fails on startup, or after a lightning strike.
Chapter 8: Troubleshooting Testing link end hardware Testing link end hardware This section describes how to test the link end hardware when it fails on startup or during operation. Before testing link end hardware, confirm that all outdoor drop cables, that is those that connect the ODU to equipment inside the building, are of the supported type, as defined in Outdoor copper Cat5e Ethernet cable on page 2-29.
Chapter 8: Troubleshooting Testing link end hardware Power LED is off Meaning: Either the PSU is not receiving power from the AC/DC outlet, or there is a wiring fault in the ODU cable. Action: Remove the ODU cable from the PSU and observe the effect on the Power LED: • If the Power LED does not illuminate, confirm that the mains power supply is working, for example, check the plug and fuse (if fitted). If the power supply is working, report a suspected PSU fault to Cambium Networks.
Chapter 8: Troubleshooting Testing link end hardware 4 Check that test point P1 on the LPU PCB corresponds to pin 1 on the RJ45. Repeat for points P2 to P8. This test is only valid if both the PSU and the ODU are disconnected. 5 Reconnect the ODU cable to the PSU. 6 Check that the PWR LED near the top right of the LPU PCB is illuminated to indicate power in the Ethernet cable. 7 If any test fails, replace or repair the cable that connects the PSU to the LPU or ODU.
Chapter 8: Troubleshooting Testing link end hardware Ethernet LED blinks irregularly Meaning: If the Ethernet LED blinks irregularly, for example two rapid blinks followed by a longer gap, this indicates that the ODU has booted in recovery mode. The causes may be: installation wiring, or a corrupt ODU software load, or sufficient time has not been allowed between a repeat power up. Action: Refer to Recovery mode on page 7-44.
