Regulatory Inf ormation

Exposure to Radio Frequency Radiation.

Interference Statement.

Canada - Industry Canada (IC).

The radiated output pow e r of the IEEE 802.11 RoamAbo ut PC Card is far below the FCC radio freque nc y exposure limits. Nevertheless, the RoamAbout PC Card shall be used in such a manner that the potential for human contact during normal operation is minimized. When using this device in combination with RoamAbout Outdoor Antenna produc t s, a certain separation distance between antenna and nearby persons has to be kept to ensure RF exposur e compliance . Refer to the Regu latory State ments as identi fied in the docume ntation tha t comes with those products for additi ona l in form ation.

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 Rul es. The se l im it s are d esi gned to pr ovid e r ea sonab l e pr otec ti on again st har mfu l inte rfe re nce in a residential installation.

This equipment gene rat es, uses, and can radiate ra dio f requency energy. If not insta ll ed and used in accordanc e with the instructi ons, it may cause harmf ul inte rfe rence to radi o commu nic atio ns. Ho wever, ther e is n o guar ant ee that interference will not occur in a particular installation.

If this equipment does cause harm ful interference to radio or televi sio n reception, which can be det erm i ne d 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:

• Reorient or relocate the r eceiving antenna.

• Increase the distance between the eq uipment and the receiver .

• Connect the equipment to an outlet on a circuit different from that to which the receiver is connected.

• Consult the deal er or an experienced radio or TV technician for help. Enterasys Networks is not respon sib le for any radio or television interferenc e caused by unauthorized

modification of the devices included in this kit, or the substitution or attachment of connecting cables and equipment other then spe ci fied by Enterasys Networks. The co rrection of interference ca used by such unauthorized modificat io n, subs ti tu ti on or a tt ac hm e nt will be the responsibility of the user.

For country-specific approvals, please consult the Radio Certification Information document included in this kit. Visit the RoamAbout Wireless web site for updated country approvals.

This Class B digital apparatus meets all requirements of the Canadian Interference-Causing Equipment Regulations.

RoamAbout 802.11b PC Card

This document provides the system requirements, installation procedure, and technical specifications for the RoamAbout 802.11b PC Card.

Before installing the PC Card, please review the Regulatory information included in the RoamAbout Radio Certification and Regulatory Information document included with the PC Card.

NOTE: The RoamAbout World Card (CSICD) does not support outdoor antennas (Yagi or omni). For outdoor solutions, use the appropriate PC Card for your country (CSIBD or CSILD). Contact your Enterasys Representative.

System Require m ents

When you install the RoamAbout PC Card, you must also install its driver. You can also download the RoamAbout drivers and documentation from the RoamAbout wireless web site: www.enterasys.com/wireless

Check the RoamAbout wireless web site frequently for driver updates. If you download a driver from the web, refer to that driver ’s release notes and readme file fo r the instr uctions to extract and install the driver. The RoamAbout PC Card Drivers CD-ROM contains the driver and installation information for the following operating systems.

• The RoamAbout NDIS3 Miniport driver supports Windows 95.

• The RoamAbout NSID4 Miniport driver supports Windows NT V4.0 or later. If you

are using Windows NT V4.0, you also need Service Pack 4 or later.

• The RoamAbout NDIS5 driver supports Windows 98, 2000, Millennium, and XP.

The Windows 2000 driver included with the operating system does not support encryption. You must update the driver with the RoamAbout Windows 2000 driver included on the RoamAbout CD-ROM.

Refer to the RoamAbout wireless web site for additional driv er s to support operating systems such as Linux, Apple, Windows CE, and DOS.

PC Card Installation

To install the PC card, perform the following steps:

1. Insert the PC Card in the PC Card slot, if available.

2. If the system does not have a PC C ard slot but h as an available ISA bus slot, install the

optional ISA adapter card. If the system does not have an ISA slot, install the optional PCI adapter. The installation instructions are in the ISA adapter kit and the PCI adapter kit.

Refer to the driver operating system directory readme on the CD-ROM to install the appropriate driver. Or, if you downloaded the driver, refer to the directory where you downloaded the files.

Radio Ranges

Signal strength can be affected by closeness to metal surfaces and solid high-density materials. The ranges listed in Table 3 provide a general guideline and may vary according to the actual physical environment where the product is used.

• In open environments, there are no physical obstructions between antennas.

• In semi-open environments, work space is divided by shoulder-height, hollow wall

elements; antennas are at desktop level.

Supported Frequency Sub-Bands

The RoamAbout PC Card supports a number of factory-programmed channels. The number of available frequencies is subject to local radio regulations as defined by local authorities.

In RoamAbout infrastructure environments, the RoamAbou t PC Card auto matically starts operation at the frequency channel that is used by the RoamAbout AP. This frequency is controlled by the LAN administrator who sets the RoamAbout AP configuration. The frequency range for the RoamAbout 8 02.11b PC Card is 240 0 - 2500 MH z. Table 4 shows the factory-set default values for the 802.11b PC Card, which are printed in bold.
