3AP Chassis
The AP includes its own bracket kit for mounting the unit to a 1.5 to 6 inch diameter
pole or part of a radio mast or tower structure.
Before continuing with AP installation, first review the general guidelines and
requirements in this chapter.
This chapter includes these sections:
◆“General Installation Guidelines” on page 23
◆“How to Mount the Unit” on page 25
◆“How to Connect External Antennas” on page 27
◆“How to Align Antennas” on page 28
General Installation Guidelines
Be sure to follow the guidelines below when choosing a location.
Caution:
The planning and installation of the AP requires professional personnel
that are trained in the installation of radio transmitting equipment. The user is
responsible for compliance with local regulations concerning items such as
antenna power, use of lightning arrestors, grounding, and radio mast or tower
construction. Therefore, it is recommended to consult a professional contractor
knowledgeable in local radio regulations prior to equipment installation.
Antenna Position When planning a location for the AP, consider these guidelines:
◆When installing for an access point service, be sure to place the unit and
external antennas in a location that can cover the intended service area.
◆Be sure there are no other radio antennas within 2 m (6 ft) of the AP.
◆Place the AP away from power and telephone lines.
◆Avoid placing the AP too close to any metallic surfaces, such as roof-installed
air-conditioning equipment, tinted windows, wire fences, or water pipes.
Chapter 3
| AP Chassis
General Installation Guidelines
– 24 –
Ethernet Cabling From the intended AP location, plan a cable route from the unit outdoors to the
power injector module indoors. Consider these guidelines:
◆The total Ethernet cable length should never be longer than 100 m (328 ft).
◆Determine a building entry point for the cable.
◆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.
Radio Interference The avoidance of radio interference is an important part of wireless network
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/n channel frequencies. Always use a channel frequency that is furthest
away from another signal.
Weather Conditions When planning outdoor networks, you must take into account any extreme
weather conditions that are known to affect your location. Consider these factors:
◆Temperature — The AP is tested for normal operation in temperatures from
-10° C to 60° C. Operating in temperatures outside of this range may cause the
unit to fail.
◆Wind Velocity — The AP can operate in winds up to 44 m/s and survive higher
wind speeds up to 66 m/s. 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 — The AP includes its own built-in lightning protection. However,
you should make sure that the unit, any supporting structure, and cables are all
properly grounded. Additional protection using lightning rods, lightning
arrestors, or surge suppressors may also be employed.
◆Rain — The AP is weatherproofed against rain. Also, prolonged heavy rain has
no significant effect on the radio signal. However, it is recommended to apply
weatherproof sealing tape around all connectors for extra protection.
◆Snow and Ice — Falling snow, like rain, has no significant effect on the radio
signal. However, a build up of snow or ice on antennas may cause links to fail. In
this case, the snow or ice has to be cleared from the antennas to restore
operation of the unit.

How to Mount the Unit
– 25 –
How to Mount the Unit
The AP can be mounted in the following ways using the included mounting
bracket:
◆To a 1.5 to 6 inch diameter pole
The AP’s mounting bracket has two main parts. One part that can be secured to a
pole using two steel-band clamps, and another part that attaches directly to the AP.
The two parts link together and allow the tilt angle of the unit to be adjusted for
antenna alignment.
How to Pole Mount Perform the following steps to mount the unit to a 1.5 to 6 inch diameter pole or
tube using the mounting bracket:
1. Using the two included steel-band clamps, thread them through the slats
provided in the pole-mount part of the bracket.
2. Place the pole-mount part of the bracket against the pole and tighten the steel-
band clamps until it is secure.

How to Connect External Antennas
When deploying an AP, you need to mount external antennas and connect them to
the unit. Two antennas are required for 2.4 GHz operation and two can be used for
5 GHz operation. These antennas are not included in the AP package.
The SMC2891W-AN unit includes an integrated high-gain antenna for 5 GHz
operation. External antennas are not required for 5 GHz operation only for 2.4 GHz
operation.
Some omnidirectional external antennas attach directly to the N-type connectors
on the unit. Other antennas may include their own mounting brackets and connect
to the unit using RF coaxial cables.
Perform these steps:
1. For external antennas with mounting brackets, mount the antennas to the
same supporting structure as the AP, within 3 m (10 ft) distance, using the
brackets supplied in the antenna package.
2. Connect the antennas either directly to the AP’s N-type connectors, or use RF
coaxial cable provided in the antenna package.

3. Apply weatherproofing tape to the antenna connectors to help prevent water
entering the connectors.
Note
:
Be sure to take account of the antenna polarization direction; all antennas in
a link must be mounted with the same polarization.
How to Align Antennas
When using the SMC2891W-AN unit with its 5 GHz integrated high-gain antenna,
you will need to accurately align the antenna with another unit in the network to
ensure optimum performance. Proper antenna alignment is particularly important
for long-range point-to-point links.
◆Point-to-Point Configurations — In a point-to-point configuration the
alignment process requires two people at each end of the link. The use of cell
phones or two-way radio communication may help with coordination. To start,
you can just point the antennas at each other, using binoculars or a compass to
set the general direction. Then you can adjust the horizontal and vertical
position to find the position where the signal is strongest and secure the unit in
that position.
◆Point-to-Multipoint Configurations — In a point-to-multipoint configuration
all SMC2891W-AN units must be aligned with a central SMC2890W-AN unit that
may be using external omnidirectional or sector antennas. The alignment
process is the same as in point-to-point links, but only the SMC2891W-AN units
require the adjustment for proper alignment.
To start, you can just point the SMC2891W-AN antenna at the central
SMC2890W-AN unit, using binoculars or a compass to set the general direction.
Then you can adjust the horizontal and vertical position to find the position
where the signal is strongest and secure the unit in that position.
Note
:
The receive signal strength of the radio signal on the local and remote unit
can be viewed using the CLI or web management interfces. Refer the Management
Guide for further information.

4Power and Grounding
This chapter focuses on how to power-on the AP. The AP can be powered using the
included PoE Power Injector or by a direct connection to a PoE LAN switch.
Connecting the AP to ground is also covered.
This chapter includes these sections:
◆“Power Injector Module” on page 29
◆“How to Ground the Unit” on page 31
◆“How to Install the Power Injector” on page 32
Power Injector Module
The AP receives power through its network cable connection using power-over-
Ethernet technology. A power injector module is included in the AP package and
provides two RJ-45 Ethernet ports, one for connecting to the AP (DATA & POWER
OUT), and the other for connecting to a local LAN switch (DATA IN).
The DATA IN port uses an MDI (that is, internal straight-through) pin configuration.
You can therefore use straight-through twisted-pair cable to connect this port to
most network interconnection devices such as a switch or router that provide MDI-
X ports. However, when connecting the access point to a workstation or other
device that does not have MDI-X ports, you must use crossover twisted-pair cable.

How to Connect to the RJ-45 Port
The connection between the AP’s RJ-45 port and the PoE power injector requires
outdoor-rated Category 5E or better Ethernet cable with RJ-45 plugs on each end.
The length of the Ethernet cable should be less than 100 meters (328 ft).
Copper Cabling
Guidelines
Before connecting the Ethernet copper cable, first plan a cable route from the AP
outdoors to the PoE power injector indoors. Consider these guidelines:
◆Make sure the cable distance does not exceed 100 meters (328 ft).
◆Determine a building entry point for the cable.
◆Determine if conduits, bracing, or other structures are required for safety or
protection of the cable.
◆Be sure to ground the outdoor-rated Ethernet cable immediately before it
enters the building. See “Grounding the Ethernet Cable” on page 41.
◆For additional lightning protection, it is recommended to use a lightning
arrestor immediately before the Ethernet cable enters the building.
10/100BASE-TX Pin

1000BASE-T Cable Requirements
All Category 5 UTP cables that are used for 100BASE-TX connections should also
work for 1000BASE-T, providing that all four wire pairs are connected. However, it is
recommended that for all critical connections, or any new cable installations,
Category 5e (enhanced Category 5) or Category 6 cable should be used. The
Category 5e and 6 specifications include test parameters that are only
recommendations for Category 5. Therefore, the first step in preparing existing
Category 5 cabling for running 1000BASE-T is a simple test of the cable installation
to be sure that it complies with the IEEE 802.3-2008 standards.
Connection Procedure Follow these steps to connect Ethernet copper cable to the AP’s RJ-45 twisted-pair

Diagnosing LED Indicators
System Self-Diagnostic Test Failure
If there is a failure of the system power-on-self-test (POST), you can use a console
connection to view the POST results. The POST results may indicate a failed
component or help troubleshoot the problem. For more information on
connecting to the console port and using the CLI, refer to the Management Guide.
Note a POST failure normally indicates a serious hardware fault that cannot be
rectified or worked around. If you encounter a POST failure, you should contact
your dealer for assistance.
Power Problems
If the power indicator does not turn on when the Ethernet cable is plugged in, you
may have a problem with the power outlet, power cord, or PoE power injector.
However, if the unit powers off after running for a while, check for loose power
connections, power losses or surges at the power outlet. If you still cannot isolate
the problem, the PoE power injector may be defective.
