Note
MeshOS 4.5 provides you the option to turn off the LEDs in the MSR2000 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 MSR2000 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 Radio status R0 and R1. 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 4.5 User Guide and the Aruba MeshOS 4.5
Command Reference Guide.

2.2 Preparing Installation Tools
The following tools may be required while installing a MSR2000.
Table 2-1 Installation tools
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. The site should be located within at least a 60% range of the 1st fresnel zone without obstacles to
provide line of sight (LOS) transmission, increase coverage capacity, and minimize the number of
necessary sites.
2. If no LOS secured, area in non-line-of-sight (NLOS) 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 in 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 MSR2000 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.

MSR2000 Installation Guide 16
3 Weatherproofing Connections
Weatherproofing your antenna and/or cable connections on your outdoor AP is essential to reliability and
longevity of your product. This process prevents water from entering the AP 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 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
•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
"Weatherproofing Directly Connected Antennas" section. For weatherproofing cable connections, see
"Weatherproofing Cable Connections" section.

MSR2000 Installation Guide 18
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 the 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 Directly Connected Antennas
First Wrapping of Tape
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 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 AP’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 AP’s case.
Figure 3-3 First Wrapping of Tape

MSR2000 Installation Guide 19
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).
