CHAPTER

Introduction
The Altitude™ 4021 Series Access Point, component of Extreme Networks®Wireless
Mobility System, links wireless 802.11a/b/g/n devices to the Summit®WM3000 Series
Controller, enabling the growth of your wireless network with a cost-effective alternative to
standard Access Points. The Altitude 4021 Series is an enterprise class 802.11n Access Point,
installed in minutes anywhere a CAT-5e (or better) cable is located.
An Altitude 4021 Series Access Point operates in dependent mode only, and requires
adoption and management by a Extreme Networks Summit WM3000 Series Controller to
receive its configuration.
An Altitude 4021 Series Access Point ships with a single dual-band radio supporting the
802.11a/b/g/n radio bands. For more information on available SKUs, refer to the following

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.

●Verify any device connected to this unit is properly wired and grounded.
●Verify there is adequate ventilation around the device, and ambient temperatures meet
equipment operation specifications.
Site Preparation
●Consult your site survey and network analysis to determine specific equipment
placement, power drops etc.
●Assign installation responsibility to the appropriate personnel.
●Identify and document where all installed components are located.
●Ensure adequate, dust-free ventilation to all installed equipment.
●Prepare Ethernet port connections.
●Verify cabling is within the maximum 100 meter allowable length.

●Wall mount slots
●Clips for suspended T-Bar mounting
●DC power connector
An Altitude 4021 Series Access Point has one RJ-45 connector supporting an 10/100/1000
Ethernet port connection and requires 802.3af compliant power from an external source.
The Access Point contains runtime firmware which enables the unit to boot after either a
power up or a watchdog reset. The runtime firmware on the Access Point can be updated
via the Ethernet interface.

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.

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.
