Compliance

FCC - Class B

This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with instructions, may cause harmful interference to radio communications. However, there is no guarantee that the interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures:

z Reorient the receiving antenna z Increase the separation between the equipment and receiver z Connect the equipment into an outlet on a circuit different from that to which the receiver is connected z Consult the dealer or an experienced radio/TV technician for help

FCC Caution: To assure continued compliance, use only shielded interface cables when connecting to computer or peripheral devices. Any changes or modifications not expressly approved by the party responsible for compliance could void the user’s authority to operate this equipment.

This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) This device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation.

CAUTION STATEMENT: FCC RF Radiation Exposure Statement

This equipment complies with FCC RF radiation exposure limits set forth for an uncontrolled environment. This equipment should be installed and operated with a minimum distance of 20 centimeters (8 inches) between the radiator and your body. This transmitter must not be co-located or operating in conjunction with any other antenna or transmitter.

Radio Frequency Interference Requirements

This device is restricted to indoor use due to its operation in the 5.15 to 5.25 GHz frequency range. The FCC requires this product to be used indoors to reduce the potential for harmful interference to co-channel Mobile Satellite systems.

CHAPTER 1

Introduction

The Aruba 52 is part of a comprehensive wireless network solution. The device works in conjunction with the Aruba 5000 WLAN Switch and can act as a wireless access point or air monitor.

As a wireless access point, the Aruba 52 provides transparent, secure, high-speed data communications between wireless network devices (fixed, portable, or mobile computers with IEEE 802.11a, 802.11b, or 802.11g wireless adapters) and the wired LAN.

As a wireless air monitor, a uniquely Aruba feature, the Aruba 52 enhances wireless networks by collecting statistics, monitoring traffic, detecting intrusions, enforcing security policies, balancing wireless traffic load, self-healing coverage gaps, and more.

Product Features

z Wireless dual-band transceiver z Dual, omnidirectional antennas for reception diversity z Protocol-independent networking functionality z 802.11a – up to 54 Mbps data rate per channel: offers a high data rate and reliable wireless

connectivity

z 802.11b – up to 11 Mbps data rate per channel: provides an alternative to wired LANs that

can dramatically cut costs

z 802.11g – up to 54 Mbps data rate per channel: backwards compatible with 802.11b z Compatible with IEEE 802.3af Power Over Ethernet (POE) z Seamless connectivity to wired LANs augment existing networks quickly and easily z Can be centrally managed, configured, and upgraded through the Aruba WLAN Switch

to take advantage of network changes and security improvements

Introduction 1

Chapter 1

7/29/03 FINAL DRAFT—CONFIDENTIAL

Ethernet Compatibility

The Aruba 52 attaches to 10/100 Mbps Ethernet (FE) LAN segments that utilize 10Base-T/100Base-TX (twisted-pair) wiring. The device appears as an Ethernet node and performs a routing function by moving packets between the wired LAN and remote workstations on the wireless infrastructure.

Radio Characteristics

For IEEE 802.11a operation, the Aruba 52 uses a radio modulation technique known as Orthogonal Frequency Division Multiplexing (OFDM), and a shared collision domain (CSMA/CA). It operates in the 5GHz Unlicensed National Information Infrastructure (UNII) band. Data is transmitted over a half-duplex radio channel operating at up to 54 Megabits per second (Mbps).

For IEEE 802.11b operation, the Aruba 52 uses the IEEE 802.11 High-Rate Direct Sequence (HRDS) specification, and a shared collision domain (CSMA/CA). It operates in the 2.4GHz Industrial/Scientific/Medical (ISM) band. The ISM band is available worldwide for unlicensed use. Data is transmitted at speeds of up to 11 Mbps.

For IEEE 802.11g operation, the Aruba 52 uses ODFM and a shared collision domain (CSMA/CA). It operates in the 2.4GHz Industrial/Scientific/Medical (ISM) band. The ISM band is available worldwide for unlicensed use. Data is transmitted at speeds of up to 54 Mbps.

Power Over Ethernet

The Aruba 52 supports the IEEE 802.3af standard for Power Over Ethernet (POE). With this feature, the Aruba 52 can accept electrical power from a compatible POE-capable device to which it is connected, directly over the FE cable. POE eliminates the need to provide separate power outlets in environments that are difficult or undesirable to wire for electricity.

The Aruba 52 supports POE only when the FE port is connected to an IEEE 802.3af compliant device (such as the Aruba 5000 WS-5032 Line Card).

Dual, omnidirectional Antennas for Wireless Communications (on sides)

The antennas swivel and should be oriented vertically (straight up and down) away from the chassis for best performance.

Air Vents (on sides)

These vents promote proper air circulation for cooling the device. Do not allow these vents to be obstructed by mounting equipment, network cables, or any other material.
