must be tied to the individual using them. Workers below must wear safety helmets.
Lightning Activity Warning
Make sure not to connect or disconnect cables during periods of lightning
activity.
A surge protective device should be installed to prevent potential damage from very
high surges, for instance, the peak surges caused by lightning.
Explosive Device Proximity Warning
Do not operate wireless network devices close to explosive merchandise or
in explosive environments if devices are not certified for operation in such an
environment, for example, in the vicinity of a gas station.
Antenna Placement Warning
Do not install any antenna near overhead power lines or other electric light,

Please always remember to protect your MSR4000 system by installation of

4 MSR4000 Installation Guide
grounding lines. The ground connection must be complete before connecting power
to the MSR4000 enclosure. The requirement of grounding is to make sure the
resistance must be less than 5 ohm between the ground termination point to
grounding tier.
Power Installation Warning
The installation of the power switch must be performed by a trained
professional technician.
The power switch is not supplied with the MSR4000. The power cord must be
assembled by a professional installer, and the final assembly must comply with
related requirements.
Solar Irradiation and High Temperature Protection
Pay attention to level of sunlight, which can increase the working
temperature of MSR4000 to higher than specifications allow.
A solar shield is provided in the Aruba standard package and should be installed to
protect any outdoor MSR4000. The Aruba Warrantee policy does not cover those
outdoor products for which Solar shields are not installed. Please contact Aruba
technical support engineers for detailed information.
RF Device Protection
Before powering up the MSR4000, the RF port must be connected to an
antenna or a valid load (not included in the standard accessories for MSR4000).
Otherwise, the RF module may be burned out. Aruba will not take any responsibility
for such damage. For RF module with power less than 100mW, in test environment,
it is allowed worked without load but should be within 30 minutes.

MSR4000 Installation Guide 5
Protection on unused RF module
The unused RF interface must be closed via configuration command and its
protective cap must be wrapped up by waterproof PVC tape to prevent from falling
off. Otherwise, the RF module may be damaged. Aruba will not take any
responsibility for such damage.

these materials to repack and return the unit to the supplier if needed.
2.2 Preparing Installation Tools
When installing MSR4000, you may need the following tools. You shall select the tools
according to the actual situation.

MSR4000 Installation Guide 15
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. The site should be located within at least a 60% range of the 1st fresnel zone without
obstacles to provide LOS transmission, increase coverage capacity, and minimize
the number of necessary sites.
2. If no LOS secured, area in 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 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 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 (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

MSR4000 Installation Guide 17
"Weatherproofing Directly Connected Antennas" section. For weatherproofing

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.

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).
