Antenna Interface

The MSR4000 requires the use of detachable outdoor-rated antennas. Select the correct antenna type to support the required frequency band and the desired coverage pattern.

The MSR4000 is equipped with eight female N-type antenna interfaces; four on the top of the AP and four on the bottom. The interfaces are grouped into diversity pairs, marked R0 (Radio 0), R1 (Radio 1), R2 (Radio 2) and R3 (Radio 3).

USB Console Interface

A USB serial console port is provided for connection to a terminal, allowing direct local management. Use the included USB console cable to connect to the AP. You can download the necessary driver for USB-

UART adapter from support.arubanetworks.com

under the Tools & Resources tab.

Ethernet Interface

The MSR4000 is equipped with a 10/100/1000Base-T Gigabit Ethernet port for wired network connectivity.

On the MSR4KP, this port also supports IEEE 802.3at Power over Ethernet (PoE), accepting 48 VDC as a standards-defined powered device (PD) from a power sourcing equipment (PSE) device, such as a PoE midspan injector. Inversely, the MSR4KAC can act as a PSE device to provide IEEE802.3af PoE power to devices connected to the Ethernet port.

Grounding Point

Always remember to protect your MSR4000 by installing grounding lines. The ground connection must be complete before connecting power to the MSR4000 enclosure. Ensure that the resistance is less than 5 ohm between the ground termination point and the grounding tier and the cross section of the grounding cable should be no less than 6 square mm.

MSR4KP LED Status Indicators

The MSR4000 include visual indicators for power, link, and radio status.

Starting with MeshOS 4.5, you can turn off the LEDs in the MSR4000 devices using the WMI and CLI. The LEDs are enabled by default. This option may be used to disable the LED lights in a MSR4000 device that is mounted in an elevated place on the city streets or residential areas, to avoid unwanted attention or disturbance. This feature turns off only the LED lights that indicate the software status, for example the RF. The LEDs that indicate the hardware status, for example Power, P/S, POE, and ETH, cannot be turned off using this feature. For additional details, refer to the Aruba MeshOS User Guide and the Aruba MeshOS Command Reference Guide .

Outdoor Planning and Deployment Considerations

Prior to deploying an outdoor wireless network, the environment must be evaluated to plan for a successful

Aruba WLAN deployment. Successfully evaluating the environment enables the proper selection of Aruba routers and antennas and assists in the determination of their placement for optimal RF coverage. This process is considered WLAN or RF planning and Aruba’s system engineers can assist in the outdoor planning process.

For WLAN systems being installed outdoors in the USA, the following requirements must be met.

1. Systems must be professionally installed by a qualified engineer familiar with WLAN, including Aruba trained partners and resellers.

2. Operation in the 5600-5650-MHz band is prohibited.

3. When within 35 km distance of a TDWR, the center frequency of the WLAN must be separated from the

TDWR center frequency by 30 MHz.

a. If the radar is operating from 5600-5610 MHz, disable the use of channel 116 (5580 MHz).

b. If the radar is operating from 5630-5650 MHz, disable the use of channel 132 (5660 MHz).

For TWDR locations in the US please refer to www.wispa.org/tdwr-locations-and-frequencies .

Scale Requirements

The potentially immense scale of outdoor deployments requires consideration of factors that may not be as important in a typical indoor deployment:







Range (distance): Range or distance between APs must be taken into account during the planning phase.

Available AP mounting locations are often far less flexible in an outdoor environment. Regardless of these outdoor restrictions, the desired goal is to achieve results similar to an indoor deployment: a

“dense” RF deployment that supports advanced Aruba features, such as efficient client roaming, and failover.

Elevation: Proper consideration and planning for elevation differences between routers (router to router) and AP to Client can be critical to success. To plan for these differences in elevation, it is important to understand the 3D coverage pattern provided by the antennas that will be deployed in the environment.

Non-Fixed Considerations: The RF environment might change on a day to day basis. Keep non-fixed items, such as shipping containers, vehicles, and future building construction, in mind when planning for an outdoor deployment.

Identifying Known RF Scatterers/Reflectors/Interferences Sources

Identifying known RF scatterers/reflectors/interference sources while out in the field during the installation phase is critical. Even though outdoor environments consist of fewer RF scatterers/reflectors/interference sources compared to indoor environments, ensure that these sources are identified and taken into consideration when installing and mounting a router to its fixed outdoor location.

Line of Sight (Radio Path Planning)

A wireless bridge or mesh link requires a “radio line of sight” between the two antennas for optimum performance. The concept of radio line of sight involves the area along a link through which the bulk of the radio signal power travels. This area is known as the first Fresnel Zone of the radio link. For a radio link, no object (including the ground) must intrude within 60% of the first Fresnel Zone.

Figure 6 illustrates the concept of a good radio line of sight.

Figure 6 Line of Sight

Radio Line of Sight

Visual Line of Sight

If there are obstacles in the radio path, there may still be a radio link but the quality and strength of the signal will be affected. Calculating the maximum clearance from objects on a path is important as it directly affects the decision on antenna placement and height. It is especially critical for long-distance links, where the radio signal could easily be lost.





When planning the radio path for a wireless bridge or mesh link, consider these factors:

Avoid any partial line of sight between the antennas

Be cautious of trees or other foliage that may be near the path, or may grow and obstruct the path.





Be sure there is enough clearance from buildings and that no building construction may eventually block the path.

For very long distance links, the curvature of the earth (20 cm per km) may need to be considered in the calculation of relative heights.


10





Check the topology of the land between the antennas using topographical maps, aerial photos, or even satellite image data (software packages are available that may include this information for your area)

Avoid a path that may incur temporary blockage due to the movement of cars, trains, or aircraft.

Antenna Height

A reliable wireless bridge or mesh link is usually best achieved by mounting the antennas at each end high enough for a clear radio line of sight between them. The minimum height required depends on the distance of the link, obstacles that may be in the path, topology of the terrain, and the curvature of the earth (for links over 3 miles).

For long-distance links, the router may have to be mounted on masts or poles that are tall enough to attain the minimum required clearance. Use the following table to estimate the required minimum clearance above the ground or path obstruction (for 5 GHz bridge links).

To avoid any obstruction along the path, the height of the object must be added to the minimum clearance required for a clear radio line of sight. Consider the following simple example, illustrated in Figure 7 .

A wireless bridge or mesh link is deployed to connect building A to building B, which is located three miles

(4.8 km) away. Mid-way between the two buildings is a small tree-covered hill. From the above table it can be seen that for a three-mile link, the object clearance required at the mid-point is 5.3 m (17.4 ft). The tree tops on the hill are at an elevation of 17 m (56 ft), so the antennas at each end of the link need to be at least

22.3 m (73 ft) high. Building A is six stories high, or 20 m (66 ft), so a 2.3 m (7.5 ft) mast or pole must be constructed on its roof to achieve the required antenna height. Building B is only three stories high, or 9 m

(30 ft), but is located at an elevation that is 12 m (39 ft) higher than building A. To mount an antenna at the required height on building B, a mast or pole of 1.3 m (4.3 ft) is needed.

!

Never construct a radio mast, pole, or tower near overhead power lines.

Local regulations may limit or prevent construction of a high radio mast or tower. If your wireless bridge or mesh link requires a high radio mast or tower, consult a professional contractor for advice.

Antenna Position and Orientation

Once the required antenna height has been determined, other factors affecting the precise position of the wireless bridge or mesh link must be considered:





Be sure there are no other radio antennas within 2 m (6 ft) of the wireless bridge or mesh link. These include other WiFi radio antennas.

Place the wireless bridge or mesh link away from power and telephone lines.





Avoid placing the wireless bridge or mesh link too close to any metallic reflective surfaces, such as roofinstalled air-conditioning equipment, tinted windows, wire fences, or water pipes. Ensure that there is at least 5 feet clearance from such objects.

The wireless bridge or mesh link antennas at both ends of the link must be positioned with the same polarization direction, either horizontal or vertical. Proper alignment helps to maximize throughput.

Radio Interference

The avoidance of radio interference is an important part of wireless link planning. Interference is caused by other radio transmissions using the same or an adjacent channel frequency. You should first scan your proposed site using a spectrum analyzer to determine if there are any strong radio signals using the 802.11a/ b/g channel frequencies. Always use a channel frequency that is furthest away from another signal.


12

!

If radio interference is still a problem with your wireless bridge or mesh link, changing the antenna direction may improve the situation.

Weather Conditions

When planning wireless bridge or mesh links, you must take into account any extreme weather conditions that are known to affect your location. Consider these factors:

 Temperature: The wireless bridge or mesh link is tested for normal operation in temperatures from -30ºC to 55ºC. Operating in temperatures outside of this range may cause the unit to fail.





Wind Velocity: The wireless bridge or mesh link can operate in winds up to 165 miles per hour. You must consider the known maximum wind velocity and direction at the site and be sure that any supporting structure, such as a pole, mast, or tower, is built to withstand this force.

Lightning: To protect against lightning induced surges, the MSR2000 requires lightning protection on the radio interface ports.

An Aruba Lightning Arrestor, AP-LAR-1, must be installed on each antenna port for protection against lightning induced surges. Failure to use an AP-LAR-1 can void the warranty of an Aruba outdoor AP model and renders the

AP susceptible to failure from lightning induced surges





Rain: The wireless bridge or mesh link is weatherproofed against rain. However, it is recommended to apply weatherproof sealing tape around the Ethernet port and antenna connectors for extra protection.

If moisture enters a connector, it may cause a degradation in performance or even a complete failure of the link.

Snow and Ice: Falling snow, like rain, has no significant effect on the radio signal. However, a buildup of snow or ice on antennas may cause the link to fail. In this case, the snow or ice has to be cleared from the antennas to restore operation of the link.

Ethernet Cabling

When a suitable antenna location has been determined, you must plan a cable route from the wireless bridge or mesh link outdoors to a suitable power and/or network source.









Consider these points:

The Ethernet cable length should never be longer than 90 m (295 ft).

Determine a building entry point for the cable (if applicable).

Determine if conduits, bracing, or other structures are required for safety or protection of the cable.

For lightning protection at the power injector end of the cable, consider using a lightning arrestor immediately before the cable enters the building

Grounding

It is important that the wireless bridge or mesh link, cables, and any supporting structures are properly grounded. Each MSR4000 access point includes a grounding screw for attaching a ground wire. Be sure that grounding is available and that it meets local and national electrical codes. Ground the access point first using the external ground stud on the unit before making any other connection.

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 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 layers, followed by a single wrap of butyl rubber, and fourlayer wrap of electrical tape. This provides good protection from water, heat, and other potential hazards that could damage your router or antennas.

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

Types of Connections

The following sections provide guidance on weatherproofing directly connected antennas ( Figure 8 ) and cable connections ( Figure 9 ). The same materials are needed for weatherproofing both types of connections but the procedure is slightly different. For weatherproofing directly connected antennas, see

Important Points to Remember

 Do not cover the weep holes on the antennas. Doing so can restrict the release 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 the each layer of tape as flat as possible. Wrinkles and folds in the tape create places for water and moisture to gather.


Weatherproofing Directly Connected Antennas

First Wrapping of Tape

1. Before wrapping the antennas, locate the weep holes ( Figure 6 ). Weep holes allow condensation that has built up inside the antenna to escape.

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

3. Cut a 4” (100 mm) strip of electrical tape from the roll. Pre-cutting the tape into strips makes in easier to maneuver the tape around the antennas and other components of the router’s case.

4. Beginning just below the weep holes, tightly wrap the connection 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.

Figure 10 First Wrapping of Tape

Pieces of tape as needed

Wrap tape from just above knurled section to base of antenna mount

Leave weep holes uncovered


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 ( Figure 11 )

3. Join the two ends by pushing them together until there is no longer a seam ( Figure 12 ).

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.

Therefore, if the antenna is facing up, you should begin wrapping at the router end of the connector. 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 connector.

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 begin again.

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 the roll. Pre-cutting the tape into strips makes in easier to maneuver the tape around the connectors and other components but is not required.

3. Beginning at the top of the connector, tightly 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.

1. Peel the cover of one end of the grounding cable (green or yellow and green grounding cable with 6 mm cross-section area) and place the bare grounding cable into the copper lug, and press firmly with the crimping pliers.

2. Fasten the copper lug to the grounding hole on the MSR4000 with the M4 x12 bolt and external-tooth washer.

Connecting the RF Cable

The RF cable is used to connect the antenna and the MSR4000.

You must install the lightning arrester between the antenna and the MSR4000


Figure 29 Connecting the RF Cable

RF Cable with N Type Connector

Lightning Arrester

Antenna Interface on MSR4000

1. Screw one end of the lightning arrester onto the antenna interface.

2. Connect the RF cable to the other end of the lightning arrester.

3. Waterproof the antenna connection with PVC insulation tape, adhesive insulation tape, and strap.

4. Place the included metal weatherproof caps over any unused antenna interfaces by turning them clockwise until hand tight.

One directional dual-polarization antenna needs two RF cables to connect to the two corresponding antenna interfaces on MSR4000. For example, if the antenna needs to connect to Radio 1 on MSR4000, the RF cables from antenna need to connect to the two antenna interfaces (Radio1) as shown in Figure 30

!

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

The Ethernet cable 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 MSR4000 side to the wall or the pole. This is to ensure that the weight of the cable does not affect the RJ45 connector.

Connecting the Power Cable (MSR4KAC)

!

Installation and service of Aruba Networks products should be performed by Professional Installers.

The MSR4KAC versions need an outdoor rated power cable to connect to a compatible AC power source.

The MSR4000 does not ship with any power cables; these are available as accessories and should be ordered separately. In addition to completed power cables, Aruba also offers an outdoor rated AC connector kit that can be used to connect a compatible power cable to the MSR4000.

 AC power source specifications (at MSR4000 interface): 100-240Vac, 100W

Powering the MSR2KAC

The MSR4KAC has two power cord variants and a kit is also offered to allow customers to assemble their own cable if the standard offerings do not meet deployment needs.

The following table summarizes the powering accessories available for the applicable SKUs for the

MSR4KAC units:

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).

Best Practices for Outdoor Connection to AC Mains

 With virtually all infrastructure equipment that is installed outdoors connection to AC mains should be accomplished with an outdoor rated junction box.

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

 In the event that a plug is wired onto the cable assembly, the electrician must follow all instructions provided while attaching a plug to the cable assemblies. The connections must be consistent with the local electrical code. The use of plugs with infrastructure equipment is suitable only for temporary installations where the nuisance tripping of the GFI plugs is considered tolerable.

Using the CKIT-AC-M

The assembly instructions for the CKIT-AC-M is shipped along with the parts. 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 solution are as follows:

 AC power cable specifications (when using AC connector kit and custom cable): minimum voltage/ current rating 250V/1A, diameter 6-12mm, rated for outdoor use
