2Hardware Installation
2.1 Installation Instructions
The Access Point can attach to a wall, mount under a suspended T-Bar or mount above a ceiling. Select a mounting
option based on the physical environment of the coverage area. Do not mount the Access Point in a location that
has not been approved in a site survey.
To prepare for the installation, perform the following:
1.Verify the contents of the box includes the intended Access Point and accessory hardware.
2.Review site survey and network analysis reports to determine the location and mounting position for the
Access Point.
3.Connect a CAT-5 or better Ethernet cable to a PoE compatible device and run the cable to the installation
site. Ensure there is sufficient cable slack to perform the installation steps.
4.Determine whether the Access Point is powered using a Power Injector system, combining data and
power to the Access Point’s GE1/PoE port or will be powered from a conventional power adapter
providing power only to the Access Point’s DC-48V connector.
2.2 Precautions
Before installing the Access Point:
•Verify the intended deployment location is not prone to moisture or dust.
•Verify the environment has a continuous temperature range between 0° C to 40° C.
Installation Guide9
2.3 Access Point Placement
For optimal performance, install the Access Point away from transformers, heavy-duty motors, fluorescent lights,
microwave ovens, refrigerators and other industrial equipment. Signal loss can occur when metal, concrete, walls
or floors block transmission. Install the Access Point in an open area or add Access Points as needed to improve
coverage.
Antenna coverage is analogous to lighting. Users might find an area lit from far away to be not bright enough. An
area lit sharply might minimize coverage and create dark areas. Uniform antenna placement in an area (like even
placement of a light bulb) provides even, efficient coverage.
Place the Access Point using the following guidelines:
•Install the Access Point at an ideal height of 10 feet from the ground.
•Orient the Access Point antennas vertically for best reception.
•Point the Access Point antennas downward if attaching to the ceiling (external antenna models only).
To maximize the Access Point’s radio coverage area, conduct a site survey to define and document radio
interference obstacles before installing the Access Point.
2.3.1 Antenna Options
Two antenna suites are supported for the single radio, dual-band AP-6521 Series Access Point. One antenna suite
supporting the 2.4 GHz band, and another antenna suite supporting the 5 GHz band. Select an antenna best suited

Installation Guide11
2.3.2 Power Injector System
The Access Point can receive power via an Ethernet cable connected to the GE1/PoE port.
When users purchase a WLAN solution, they often need to place Access Points in obscure locations. In the past, a
dedicated power source was required for each Access Point in addition to the Ethernet infrastructure. This often
required an electrical contractor to install power drops at each Access Point location. The Power Injector merges
power and Ethernet into one cable, reducing the burden of installation and allowing optimal Access Point
placement in respect to the intended coverage area.
The Power Injector (Part No. AP-PSBIAS-2P2-AFR) is an 802.3af PoE injector. The Access Point can only use a Power
Injector when connecting to the Access Point’s GE1/PoE port. The Power Injector is separately ordered and not
shipped with the Access Point. A separate Power Injector is required for each Access Point comprising the network.
The Power Injector has no On/Off power switch. The Injector receives power and is ready for device connection and
operation as soon as AC power is applied. Refer to the Installation Guide shipped with the Power Injector for a
description of the device’s LEDs.The Power Injector can be installed free standing, on an even horizontal surface or
wall mounted using the Power Injector’s wall mounting key holes.

The following guidelines should be adhered to before cabling the Power Injector to an Ethernet source and an
Access Point:
•Do not block or cover airflow to the Power Injector.
•Keep the Power Injector away from excessive heat, humidity, vibration and dust.
•The Power Injector isn’t a repeater, and does not amplify the Ethernet signal. For optimal performance,
ensure the Power Injector is placed as close as possible to the Ethernet switch. This allows the Access
Point to be deployed away from power drops.
•Ensure the cable length from the Ethernet source (host) to the Power Injector and Access Point does not
exceed 100 meters (333 ft).
CAUTIONTo avoid problematic performance and restarts, disable POE from a
wired controller port connected to an Access Point if mid-span power
sourcing equipment (PSE) is used between the two, regardless of the
manufacturer.
CAUTIONEnsure AC power is supplied to the Power Injector using an AC cable
with an appropriate ground connection approved for the country of
operation.
NOTEIf not using the Power Injector to power the Access Point, the only other
approved power solution is the standard power supply (Part Number
PWRS-147376-01R). The standard power supply does not converge data
and power in one cable, and requires a separate data Ethernet
connection in addition to a power connection. This product is intended to
be supplied by a listed power adapter marked “Class 2” or “L.P.S” (or
“Limited Power Source”) and rated from 48Vdc, 0.27A minimum.
