For Additional InformationTo order any of the following publications, contact your Stratex Networks Sales or Help
Desk representative at the numbers listed above.
R&TTE Directive 99/5/EC
For information regarding the R&TTE Directive and intended use table, refer to
Appendix C.
Health and SafetyBecause Stratex Networks is extremely concerned about the safety of its radio equipment
during both deployment and operation, it adheres to the following common safety
practices. These practices ensure that the equipment meets relevant US national safety
standards as well as European standards, as outlined in IEC Publication 60950.
Stray Radio Frequency (RF) Radiation The radio equipments RF assemblies are
constructed to a very high mechanical standard. Protection from RF Burns The equipment does not generate RF fields in enough
intensity to cause RF burns, however potential hazards include looking into or stand-
ing in front of the active antenna aperture while the equipment is operating. Looking
into the waveguide antenna port of the ODU is also very dangerous to the eyes when
the transmitter is on.
Hazardous Materials No hazardous materials are used in the construction of theequipment and, therefore, no special handling/disposal procedures need to be fol-
lowed.
Surface Temperatures While surfaces of the equipment do become warm duringoperation due to normal heat dissipation, the temperatures reached are not high enough
to be hazardous.
Flammability The equipment is designed and constructed to minimize the risk ofsmoke and fumes under fire conditions.
Lifting Equipment Care should be taken when hoisting or lifting the ODU duringinstallation or maintenance.

Verifying the System Configuration
After unpacking the equipment, check that the basic components for your particular
system configuration have been included in the shipment. See the Possible Configurations
section on page 84for examples of both non-protected and protected configurations. To
check your specific configuration, see the next section, Checking Equipment Part Number
Labels.
Once the XP4 Plus is installed and powered up, also check that the configuration settings
are correct, including the ODU frequency band, T-R spacing, capacity, and IDU
configuration. See Chapter 4, Configuring the XP4 Plus for more information on
checking the configuration settings.
Basic Components
The number of XP4 Plus components you receive from Stratex Networks depends on
whether you have ordered a non-protected or a protected system. A protected systemincludes an additional radio that serves as a backup for the first radio if data transmission
is interrupted for any reason. The following tables list the parts included for one complete
link for both non-protected and protected systems of various capacities.
* Cables and connectors can be ordered through Stratex Networks, but are shipped sepa-
rately from other components.

Installing the Cable
This section assumes that pre-planning of the link has occurred (path budgeting and
survey) to ensure good line-of-sight between the two link ends and cable run estimations.
For more information on pre-planning, see the Stratex Networks Standard Practices
Guide.
Installation Guidelines
Below are some guidelines to follow when installing coaxial cable:
When installing the cable between the IDU and ODU, avoid excessive bending. Runthe cable where it is reasonably well protected and will not rub against sharp edges or
overly abrasive surfaces. We recommend that you use one cable tie every meter.
Use the crimp tool and die specifically designed for the connectors and cable beingused (see Table 1-15). Use of generic crimp tools may result in sub-standard physical
connections that deteriorate the quality of the electrical transmission. Leave a U-bend, (also known as a drip loop) in the cable where it attaches to the
ODU. This prevents water from running down the cable onto the ODU connection
point and allows slack for re-positioning the antenna if necessary.
When connecting the terminated indoor/outdoor cable to the ODU and IDU, the N-type connectors should be tightened by hand. Using a tool such as pliers to tighten the
N-type connectors could result in damage to the connectors, the equipment, or both.
Cable and Connector Specifications
A 50-ohm coaxial cable is used to connect the IDU to the ODU. Only one cable is
required to connect the IDU to the ODU. Both ends of the cable must be terminated with
compatible N-type male connectors. For more information, see Terminating the IDU/ODU Coaxial Cableon page 1-14. The N-type connectors are not supplied with the radio
equipment unless requested by the customer because the type of connector required
depends on the type of cable used for each installation.
The number of N-type connectors required varies according to the radio configuration and
whether lightning arrestors are used (see Table 1-14). Connectors must be crimpable.
The length of cable needed also depends on the type of cable used and the power supply
voltage as shown in Table 1-15.

Terminating the IDU/ODU Coaxial Cable
The following instructions apply to a Belden 9913, a Belden 9273, or an LMR400 RG-8-
type cable.
To terminate the coaxial cable:
1 Cut the end of the cable evenly. Strip the cable to the dimensions shown below (refer to
the Strip Dimension row in Table 1-15 for the specific dimensions for each cable.) All
cuts should be sharp and square. Do not nick the braid, dielectric, or center conductor.
Notes: If you are using strain relief or heat shrink tubing, slide it onto the
cable now. Because the center conductor will be crimped, it is not
necessary to tin the contact.
2 Slide the ferrule over the cable.
3 Flare the end of the cable braid slightly to prepare for contact insertion. (Do not comb
out braid!) Slide the contact over the center conductor until it butts against the cable
dielectric. The center conductor should be visible through the inspection hole in the
contact.
4 Crimp the contact in place. Use the die set cavity specifications included in Table 1-15
for the contact (refer to the Hex Crimp Data row/Cavity for Contact).

5 Insert the cable assembly into the body assembly. Push cable assembly forward until
the contact snaps into place within the dielectric.
6 Slide the ferrule over the braid until it butts against the back of the connector. Crimp the
ferrule with a crimp tool using the die set cavity specifications included in Table 1-15
(refer to the Hex Crimp Data row/Cavity for Ferrule). Trim any extra braid.
Weatherproofing the Cable
The cable connection to the ODU should be weatherproofed using the cable-connector
weatherproof sleeve provided in the ODU Installation Kit or weatherproof tape provided
in an alternative installation kit. The two methods for weatherproofing are described
below.
Using a Weatherproof Sleeve
The ODU installation kit includes a short cardboard spacer, a weatherproof sleeve on a
cardboard tube, and a cable tie (see Figure 1-5).

Using Weatherproof Tape
An alternative ODU installation kit includes 30 inches of Scotch 70 weatherproof tape,
which is a high-temperature splicing tape composed of self-fusing inorganic silicone
rubber with an easy stripping liner.
To weatherproof the cable connector using weatherproof tape:
1 Attach the coaxial cable to the ODUs N-connector fitting.
2 Using mild tension, remove the backing from the weatherproof tape and wrap the entire
N-connector termination, from the ODU N-connector threads to one inch past the cable
connector.
3 Using mild tension and without stretching the tape, wrap the entire N-connector
termination with an additional layer of half-lapped tape from the ODU N-connector
threads to one inch past the cables N-connector. Before fusion takes place, press the

Grounding
Proper grounding of equipment and structures is essential to prevent electrical damage to
the XP4 Plus system. This manual assumes that the installation site grounding is as shown
in Figure 1-7.
Warning: Grounding of all equipment at a radio site is required. Without
proper grounding, voltage potentials between components of
the system can cause electrical damage when interconnecting
cables are installed.
It is recommended that the ODU be installed with lightning protection, including lightning
arrestors. Also, to avoid surge current caused by lightning circulating to the equipment
earth system, connect the equipment earth system (true ground) to the lightning rod
ground. For more information, see theStratex NetworksStandard Practices Guide.
Note: Ground wires and hardware are not provided in the installation kit,
however grounding kits can be ordered separately.

Grounding the IDU
The IDU frame is grounded through mounting hardware to either a 19- or 23-inch
equipment rack. The equipment rack must be connected to station or earth ground (seeFigure 1-7.) A #6 ground wire connects from the copper bus bar located at the top of the
equipment rack to the station ground bar. The ground bar should be installed as close to
the entrance of the building as possible (see Figure 1-9).
Figure 1-8. Frame Grounding the IDUTo ground the IDU:
1 Ensure that each surface of the IDU, IDU L-bracket, and equipment rack is clean and
free of rust or corrosion.
If the equipment rack is painted, remove the paint around the racks mounting screw.
2 Secure the IDU to the rack with mounting hardware.
3 Terminate a length of #6 wire to the station ground bar, as well as to any cross-connect
panels or other termination equipment.
4 Terminate the other end of the #6 wire with a 12x10x32 ground lug and secure to the
copper bus bar located at the top of the rack (see Figure 1-8) using a 10-32 rack screw.
5 Terminate a length of #14 green PVC insulated stranded copper wire with a 12x8x32ground lug and attach to the grounding stud located on the IDU L-bracket.
6 Terminate the other end of the #14 green PVC insulated stranded copper wire with a
12x10x32 ground lug and secure to the copper bus bar located at the top of the
equipment rack using a 10-32 rack screw.

Grounding the ODU
A suitable #12 ground wire must connect the ODU ground lug (Figure 1-10)to an
appropriate ground point on the antenna mounting or tower. This connection is site-dependent. The surface of all ground wire contact points must be clean to ensure a low-
resistance connection.
Figure 1-10. Frame Grounding the ODU
To ground the ODU:
1 Locate an attachment point for the ground such as a pole, tower bar structure or terminal
strip. The Universal round Member Adapter should be installed on the tower structure.
2 Remove any oxidation, zinc coating paint, or dirt from a surface over one-half inch
(13 mm) area surrounding the ground point.
3 Apply a coating of conductive grease to the wire and surrounding ground point to
ensure good electrical contact.
4 Terminate a length of #12 (3.3 mm2) wire with an M6 or 1/4x20 ground lug to the area
that was prepared on the pole, tower bar structure, or terminal strip.
5 Terminate the other end of the #12 (3.3 mm2) wire to one of the ODU grounding studs.
To connect the ground wire to the ODU, refer to the instructions on page 125.Note: After tightening the connection, remove any excess conductive
