Chapter 6: Installation Installing external antennas for a connectorized ODU Page 6-22 Figure 42 Lower bracket attached to AP antenna Figure 43 Completed AP and antenna assembly Attaching and weatherproofing a N-type antenna connector The following procedure should be used to weatherproof the N type connectors fitted to the connectorized ODU (AP/SM/BH) and antenna. This procedure must be followed to ensure that there is no moisture ingress at the radio ports. Failure to properly seal N-type antenna connectors can result in poor link performance or complete loss of radio communication. Note Cambium recommends to assemble the antenna, attach the ODU and cabling, and to seal the RF connections before installing the unit at the deployment site. Note N type connectors should be tightened using a torque wrench, set to 15 lb in or 1.7 Nm. If a torque wrench is not available, N type connectors may be finger tightened.
Chapter 6: Installation Installing external antennas for a connectorized ODU Page 6-23 To weatherproof an N type connector, proceed as follows: 1 Ensure the connection is tight. A torque wrench should be used if available. 2 Wrap the connection with a layer of 19 mm (0.75 inch) PVC tape, starting 25 mm (1 inch) below the connector body. Overlap the tape to half-width and extend the wrapping to the body of the AP. Avoid making creases or wrinkles: 3 Smooth tape edges: 4 Cut a 125mm (5 inches) length of rubber tape (Scotch 3M Professional Grade: D.C.J. No. 06147 or equivalent): 5 Expand the width of the tape by stretching it so that it will wrap completely around the connector and cable:
Chapter 6: Installation Installing external antennas for a connectorized ODU Page 6-24 6 Press the tape edges together so that there are no gaps. The tape should extend 25mm (1inch) beyond the PVC tape: 7 Wrap a layer of 50 mm (2 inch) PVC tape from bottom to top, starting from 25 mm (1 inch) below the edge of the self-amalgamating tape, overlapping at half width. 8 Repeat with a further four layers of 19 mm (0.75 inch) PVC tape, always overlapping at half width. Wrap the layers in alternate directions: Second layer: top to bottom. Third layer: bottom to top. Fourth layer: top to bottom. Fifth layer: bottom to top. The bottom edge of each layer should be 25 mm (1 inch) below the previous layer. 9 Completed weatherproof connection: Note A video of this procedure can be found at: https://www.youtube.com/watch?v=a-twPfCVq4A
Chapter 6: Installation Installing external antennas for a connectorized ODU Page 6-25 Attaching the AP and antenna to the mount point 1 Attach the upper bracket of the antenna to the mount point by closing the rear strap around the pole and tightening the (2) serrated flange nuts using a 13mm spanner wrench. These must be tightened evenly on the pol to avoid jumping/stripping threads. Figure 44 Attaching the AP antenna upper bracket to the pole 2 Attach the lower bracket of the antenna to the mount point by closing the rear strap around the pole and tightening the (2) serrated flange nuts using a 13mm spanner wrench. These must be tightened evenly on the pole to avoid jumping/stripping threads. Figure 45 Attaching the AP antenna lower bracket to the pole 3 Use a local map, compass, and/or GPS device as needed to determine the direction that one or more APs require to each cover the 90° sector.
Chapter 6: Installation Installing external antennas for a connectorized ODU Page 6-26 4 Choose the best mounting location for your particular application. Note Use the embedded spectrum analyzer or a commercial analyzer to evaluate the frequencies present in various locations. OFDM APs need not be mounted next to each other. They can be distributed throughout a given site. However, the 90° offset must be maintained. If you want to collocate these APs with PMP 100 Series APs of the 5.4-GHz frequency band range, plan to allow at least 25 MHz of separation between their center channels. 5 Secure a ground strap to the ground lug on the back of the AP. 6 Secure the ground strap to the pole, tower, or other trusted ground. 7 The bracket of the standard antenna has provision for measured down tilt. The recommended practice is to use one of the many radio analysis and mapping tools or on-line tools to calculate down tilt based on antenna height above the service area. The proper angle of tilt can be calculated as a factor of both the difference in elevation and the distance that the link spans. Even in this case, a plumb line and a protractor can be helpful to ensure the proper tilt. This tilt is typically minimal. The number of degrees to offset (from vertical) the mounting hardware leg of the support tube is equal to the angle of elevation from the lower module to the higher module (<B in the example provided in Figure 46Error! Reference source not found.).

Chapter 6: Installation Installating CMM4 Page 6-40 Installating CMM4 The Cluster Management Module 4 (CMM4) provides power, sync, and network connectivity for up to eight APs, backhauls, and Ethernet terrestrial feeds in a variety of configurations. The CMM4 provides • Sync over Power over Ethernet and integrated surge suppression on the controller board for up to 8 APs or BHs. Both a custom 30 VDC power scheme and a custom 56 VDC power scheme are available. Neither is the same as the later IEEE Standard 802.3af, and neither is compatible with it. • Managed switching using a hardened EtherWAN switch (1090CKHH models). The CMM4 ships with a 14-port EtherWAN switch and is also available without a switch. The CMM4 originally shipped with a 9-port EtherWAN switch. • Surge suppression on the controller board for the incoming 30V DC and 56V DC power lines and GPS coax cable. • Auto-negotiation on the Ethernet ports. Ports will auto-negotiate to match inputs that are either 100Base-T or 10Base-T, and either full duplex or half duplex, when the connected device is set to auto-negotiate. Alternatively, these parameters are settable. • An always-on NTP (Network Time Protocol) server that can provide date and time to any radio that can reach the CMM’s management IP address. • CNUT can be used to upgrade th CMM-4 software. PMP/PTP 450i can use the CMM4’s EtherWan switch for their network connectivity. Note The 56V of a CMM4 needs to go through the adapter cable (part number N000045L001A) as shown in Figure 13 on page 2-24. The CMM4 56V power adapter cable can be prepared by swapping pins 5 and 7.
