The Altitude 4021 Series Access Point is approved under MODEL: NCAP-500.
Extreme Networks recommends the Access Point receives power and transfer data through
the same CAT-5e (or better) Ethernet cable using an Extreme Networks approved Power
Injector. The Power Injector (Part No. AP-PSBIAS-2P2-AFR) is an 802.3af PoE injector. For
more information, see “Power Injector System” on page 12.
A separate power supply (Part No. PWRS-147376-01R) is available if you do not wish to use
a Power Injector. This standard power supply just supplies power to the Access Point’s
power connector and does not converge power and Ethernet within a single cable
connection.
The Altitude 4021 Series Access Point requires adoption by a Summit WM3000 Series
Controller to receive its configurations. For information, see “Defining a Basic
Configuration” on page 23.

Hardware Installation
Installation Instructions
An Altitude 4021 Series Access Point can attach to a wall, mount under a suspended T-Bar
or mount above a ceiling. Selecting 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 an installation, perform the following:
1Verify that the contents of the box includes the intended Access Point and accessory
hardware.
2Review site survey and network analysis reports to determine the location and mounting
position for the Access Point.
3Connect a CAT-5e 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.

Chapter 2: Hardware Installation
Altitude™ 4021 Series Access Point Installation Guide
10
4Determine whether the Access Point is powered using a Power Injector system,
combining data and power to the Access Point’s GE1/PoE port, or is powered from a
conventional power adapter providing power only to the Access Point’s DC-48V
connector.
Precautions
Before installing an 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.
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.

Access Point Placement
Altitude™ 4021 Series Access Point Installation Guide
11
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, Extreme Networks recommends
conducting a site survey to define and document radio interference obstacles before
installing the Access Point.
Antenna Options
Extreme Networks supports various antennas for the single radio, external antenna dual-
band, Altitude 4021 Series Access Point. These antennas support the 2.4 GHz band, the 5
GHz band, or both. Select an antenna best suited to the intended operational environment
of your Access Point.
For example, pictured below are two popular dual-band, omni-directional antennas for
typical indoor coverage (ML-2452-APA2-01 for Black and ML-2452-APAG2A1-02 for White).

Chapter 2: Hardware Installation
Altitude™ 4021 Series Access Point Installation Guide
12
For a more exhaustive overview of the antennas supported by the Extreme Networks
Access Point family, refer to the Enterprise Wireless LAN Antenna Specification Guide and
Enterprise Wireless LAN Antenna Specification Guide Addendum documents available from
http://www.extremenetworks.com/go/documentation.
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 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.

Access Point Placement
Altitude™ 4021 Series Access Point Installation Guide
13
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).

Chapter 2: Hardware Installation
Altitude™ 4021 Series Access Point Installation Guide
14
CAUTION
To 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.
CAUTION
Ensure AC power is supplied to the Power Injector using an AC cable with an appropriate
ground connection approved for the country of operation.
NOTE
If 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.
Wall Mount Installation
To support wall mount installations, the Access Point is fastened directly to a flat wall
surface. The wall should be of gypsum board, plaster, wood or concrete in composition.
CAUTION
An Access Point should be wall mounted to concrete or plaster-wall-board (dry wall) only. Do
not wall mount the Access Point to combustible surfaces.
To install the Access Point to a wall:
1Orient the Access Point by either its width or length.
2Mark the mounting surface at the target screw insertion points.
