2.2 Preparing Installation Tools

Type

Tools

Screwdriver, adjustable spanner, vice, safety belt, hard hat, power

The following tools may be required while installing a MSR4000:

Table 2-1 Installation Tools List

board (220 VAC or as required by local regulation), POE power

General tools

injector, crimping pliers, electric sol deri ng iron, welding wire, PVC
insulation tape, adhesive insulation tape, strap, insulation tools

2.3 Examining the Installation Site

1. For sites that are providing mesh connections to other units, installation location
should be selected to provide line-of-sight (LOS) with clearanc e of obstacles of at
least 60% of the first Fresnel zone.

2. If the area is not LOS secured, non LOS area could be covered as well, but the
distance of coverage and area of coverage are dec reased; mor e sit es are neede d to
provide coverage for same area than as compared to the LOS scenario.

3. Interference must be considered in site selection. New site should avoid known
interference, unless the interference is controllable.

4. Keep the MSR4000 away from plac es that are susc eptible to hig h temperatur e, dust,
harmful gas, inflammable, explosive, electromagnetic interference (high power radar,
radio station and transformer), unstable voltage, heavy vibration, or loud noise. In
engineering design, the site shoul d be selected according to the network planning
and technical requirements of communications equipment, as well as the
considerations such as climate, hydrology, geolo gy, earthquake, electric power, and
transportation.

MSR4000 Installation Guide 15

3 Weatherproofing Connections

Weatherproofing your antenna and/or cable connections on your outdoor router is essential
to reliability and longevity of your product. This process prevents water from entering the
router or the antennas through the connectors.

A good weatherproofing job consists of three wrappings:

1. Electrical tape

2. Butyl rubber

3. Electrical tape

The first wrapping of tape should be at least two lay ers, followed by a single wrap of butyl
rubber, and four-layer wrap of electrical tape. This provides good protection from water, heat,
and other potential hazards that could damage you r AP or antennas.

Additionally, wrap your connections such that water is always directed down and away from
connections.

3.1 Required Items and Tools

• 3/4” (19 mm) Vinyl Electrical Tape (waterproofing type)

• Butyl Rubber Tape

• Knife or Box Cutter

3.2 Types of Connections

The following sections provide guidance on weat herproofing directly connected antennas
(Figure 3-1) and cable connections (Figure 3-2). The same materials are needed for
weatherproofing both types of connections but the procedure is slightly different. For
weatherproofing directly connected antennas, see the Weatherproofing Antennas Connected

Directly to the MSR4000 section. For weatherproofing cable connections, see the
Weatherproofing Cable Connections section.

16 MSR4000 Installation Guide

Figure 3-1 Antennas Connected Directly to the MSR4000

Figure 3-2 Cable connections

MSR4000 Installation Guide 17

3.3 Important Points to Remember

• Do not cover the weep holes on the antennas. Doing so can restrict the releas e of
condensation from the antennas.

• Proper weatherproofing is not a fast process. Set aside ample time to complete the
steps outlined below.

• When wrapping, make each layer of tape as flat as possible. Wrinkles and folds in
the tape create places for water and moisture to gather.

3.4 Weatherproofing Antennas Connected Directly to the MSR4000

First Wrapping of Tape

Note

The following instructions assume that you have installed a lightning arrestor between
your router and the antennas.

1. Before wrapping the antennas, locate the weep hol es (Figure 3-1). Weep holes allow
condensation that has built up inside the antenn a to escape.

2. Prepare the antenna connector and the light ning arrestor by cleaning and drying it.

3. Cut a 4” (100 mm) strip of electrical tape from t he roll. Pre-cutting the tape into strips
makes it easier to maneuver the tape around the antennas and other components of the
router’s case.

4. Beginning at the antenna connector on t he router and stopping three-quarters of the
length of the antenna connector, tightly wrap the connec tion with a layer of the 3/4”
(19mm) electrical tape. Overlap the tape to a half-width.

5. Repeat steps 3 and 4 until the wrapping extends all the way to the router’s case.

18 MSR4000 Installation Guide

Figure 3-3 First Wrapping of Tape

Wrapping of Butyl Rubber

1. Cut a 3/4” (19 mm) strip of butyl rubber.

2. Wrap the strip of rubber around the taped connector (F i gure 3-4).

3. Join the two ends by pushing them together until t here i s no longer a seam (Figure 3-5).

MSR4000 Installation Guide 19

Figure 3-4 Butyl Rubber Placement

Figure 3-5 Butyl Rubber Wrap

20 MSR4000 Installation Guide

Second Wrapping of Tape

1. Cut a 4” (100 mm) strip of electrical tape from the roll.

2. Where you begin wrapping depends on the orientation of the antenna. Water should
flow in the opposite direction of the wrapping to prevent water from entering the
connector between the layers of tape. Therefor e, if the antenna is facing up, you should
begin wrapping at the router end of the connect or. This will ensure that your fourth and
final layer will be layered correctly. Conversely, if your antenna is facing down, you
should begin wrapping on the antenna end of the connec tor.

3. After completing the fourth layer of tape, check your work to ensure there are no places
where water can collect. If there are, you must smooth out those areas with additional
layers of tape or remove the weatherproofing and begi n again.

Figure 3-6 Completed Wrapping (Antenna on Top of the Router)

4. Repeat this process for all connectors.

MSR4000 Installation Guide 21

3.5 Weatherproofing Cable Connections

First Wrapping of Tape

1. Prepare the antenna connector by cleaning and drying it.

2. Cut a 4” (100 mm) strip of electrical tape from t he roll. Pre-cutting the tape into strips
makes it easier to maneuver the tape around the connectors and other components but
is not required.

3. Beginning at the top of the connector, t ight l y wrap the connection with a layer of the 3/4”
(19mm) electrical tape. Overlap the tape to a half-width.

4. Repeat steps 3 and 4 until the wrapping extends all the way to the cable’s insulation.

Figure 3-7 First Wrapping of Tape

Wrapping of Butyl Rubber

1. Cut a piece of butyl rubber large enough to wrap around the connector and extended
past the first layer of tape.

2. Wrap the strip of rubber around the taped connector (F i gure 3-8).

3. Join the two ends by pushing them together until t here i s no longer a seam (Figure 3-9).

22 MSR4000 Installation Guide

Figure 3-8 Butyl Rubber Placement

Figure 3-9 Butyl Rubber Wrap

Second Wrapping of Tape

1. Cut a 4” (100 mm) strip of electrical tape from the roll.

2. Using 3/4” (19mm) electrical tape, begi n wrapping at the connector and create four
layers.

3. After completing the fourth layer of tape, check your work to ensure there are no places
where water can collect. If there are, you must smooth out those areas with additional
layers of tape or remove the weatherproofing and begi n again.

Note
One directional dual-polarization antenna needs two RF cables to connect to two
corresponding antenna interfaces on MSR4000. For example, if the antenna needs to
connect to Radio 0 on MSR4000, the RF cables from antenna needs to connect to Antenna
1 (Radio 0) interface and Antenna 2 (Radio 0) interf ace in Figure 4-13.

4.5 Connecting the Ethernet Cable

To ensure that MSR4000 maintains Ethernet connectivity and Power over Ethernet (PoE),
you must use the weatherproof connector kit and install it using the steps below.

Note

 Failure to use the weatherproof connector kit can lead to connectivity and PoE issues.

Figure 4-14 Weatherproof Connector Kit

1. Hold the clamp ring (4) vertic ally, with the wide end facing up, and pl ace the locknut (3)
over it.

2. Drop the waterproof connector sock et (2) into the locknut/clamp ring items (3, 4), wit h
the RJ45 connector opening facing up, and screw the socket into the threads on the
clamp ring.

3. Place the sealing nut (7) over an Ethernet cable (without a connector attached to the
end).

4. Place the seal bolt (6) over the Ethernet cable.

5. Strip off about 55mm (2 inches) of the outer Et hernet c able sheath t o expose the ground
wire and other pair wires.

6. Insert all pair wires into the two shield rings (5).

7. Make the ground wire attach to the narrow end of the inner ring and pl ace the outer ring
over the narrow end of the inner ring.

8. Insert the Ethernet cable i nto the narrow end of the clamp ring and pass it through the
opening end of waterproof connector socket.

9. Using a crimping tool, attach t he included shielded RJ45 connector.

10. Slide the shield rings up the E thernet c able and i n sert it into t he narrow e nd of the clamp
ring.

11. Pull the Ethernet cable so the shielded RJ45 connector fits into the RJ45 shaped

opening in the wide end of the weatherproof connector socket.

Note

For outdoor use, the RJ45 must be installed with a waterpro ofing gasket.

12. Slide the sealing bolt over the narrow end of the clamp ring and hand tighten it.

13. Thread the sealing nut onto the sealing bolt.

14. Insert the Ethernet cable connector into the Ethernet interface and hand-tighten the

Note

• The Ethernet c abl e and power cable need proper drip loops. Drip loops prevent
water from entering the router through the connectors.

• It is recommended to fix the Ethernet cable near the MSR2000 side to the wall or the
pole. This is to ensure that the weight of the cable does not affect the RJ45 connector.

4.6 Connecting the Power Cable (MSR4KAC)

The MSR4KAC version needs an outdoor rated power cable to connect to a compatible AC
power source.

Note
The MSR4000 does not ship with any power cables; these are available as accessories
and should be ordered separately.

• AC power source spec i fications (at MSR4000 interface): 100-240Vac, 100W

4.6.1 Powering the MSR4KAC

The MSR2KAC comes with two power cord variants and a kit is also offered to allow
customers to assemble their own cables if the s tandard offerings do not meet deployment
needs.
The following table summarizes the powering accessories available for the MSR2KAC:

The difference between the NA and INTL AC cable part is the color coding of the conductors.
.

• The North American cable uses Black (Hot), White (Neutral), and Green (Ground).

• The INTL part follows the international schema of Brown (Hot), Blue (Neutral) and

Yellow/Green (Ground)

4.6.2 Best practices for Outdoor Connection to AC Mains

• With virtually all infrastructure equipment that is i nstalled outdoors connection to AC
mains should be accomplished with an outdoor rat ed ju nction box.

Note
The connection to the AC mains must be implemented by a qualified resource in a
manner that is consistent with the electric al code in force in the jurisdiction of
deployment. In many countries a licensed elect rician must perform this operation. In
Japan, this would require an electrician cert ified by the Ministry of Economy, Trade, and
Industry.

• In the event that a plug i s wired onto the cable assembly, the electric ian must follow

4.6.3 Using the CKIT-AC-M

The assembly instructions for the CKIT-AC-M are shipped along wit h the part. All instructions
must be followed to ensure proper assembly of the connector onto the cable.

The specifications for third-party cables used with the CKIT are as follows:
