Note
Starting with MeshOS 4.5, you can turn off the LEDs in the MSR4000 devices using the
WMI and the 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.

2.2 Preparing Installation Tools
The following tools may be required while installing a MSR4000:
Table 2-1 Installation Tools List
Type
Tools
General tools
Screwdriver, adjustable spanner, vice, safety belt, hard hat, power
board (220 VAC or as required by local regulation), POE power
injector, crimping pliers, electric soldering 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 clearance 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 decreased; more sites are needed 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 places that are susceptible to high temperature, 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 should be selected according to the network planning
and technical requirements of communications equipment, as well as the
considerations such as climate, hydrology, geology, earthquake, electric power, and
transportation.

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 layers, 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 your 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 weatherproofing 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.

18 MSR4000 Installation Guide
3.3 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 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 holes (Figure 3-1). Weep holes allow
condensation that has built up inside the antenna to escape.
2. Prepare the antenna connector and the lightning arrestor 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 it easier to maneuver the tape around the antennas and other components of the
router’s case.
4. Beginning at the antenna connector on the router and stopping three-quarters of the
length of the antenna connector, 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.

MSR4000 Installation Guide 19
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 (Figure 3-4).
3. Join the two ends by pushing them together until there is no longer a seam (Figure 3-5).
