FCC Part 15 Rules Compliance This Device complies with Part 15 of the FCC Rules. Operation is subject to the following conditions:

This device may not cause harmful interference This device must accept any interference received, including interference that may cause undesired operation. The FiberLeap Access unit has no user accessible controls and may not be modified or altered in any way. Changes or modifications to the equipment could void the users warranty. FCC RF Exposure Compliance The Federal Communications Commission (FCC), with its action in General Docket 93-62, November 7, 1997, has adopted a safety standard for human exposure to Radio Frequency (RF) electromagnetic energy emitted by FCC regulated equip-

ment. Telaxis subscribes to the same safety standard for the use of its products. Proper operation of this equipment will result in user exposure far below the Occu-

pational Safety and Health Act (OSHA) and Federal Communications Commission limits. FCC ID# P57-AU2006 Safety Notice This unit has been tested for RF emission levels and found not to exceed the FCC RF exposure requirements for occupational and general public exposure. Even though the RF levels external to the unit are not hazardous to humans, Telaxis believes it is prudent to minimize all exposure to RF emissions and therefore recommends the installation be such that the RF beam emitted by the antenna be positioned over the heads of any personnel working in the vicinity. WARNING DO NOT position FiberLeap Access Unit LOS (Line of Site) in such a manner that the antenna beam is directed towards areas where maintenance personnel might be working while the unit is operating. Service Precautions Failure to follow these installation instructions could damage the equipment and/or improper operation may result. FiberLeap is designed and sold for installation and maintenance by trained, qualified professionals. For service, the unit must be returned to Telaxis CUSTOMER ASSISTANCE CENTER. Telaxis P/N 50315 745 REV. ED1 2 1 Overview Application Figure 1 FiberLeap Link Overview The FiberLeap product is designed to extend the reach of fiber optic networks through wireless connections where installation barriers and high cost make installing additional fiber connections less desirable. Telaxis has developed this product to enable direct fiber optic connection and transmission of fiber optic signals over a wireless link without the use of conventional modems. These fiber extension links function, and can be managed and serviced, as if they were a length of fiber optic cable.

Mast Mount Installation Instructions 3 Getting Started Before initiating the actual installation of the Access Unit, certain other activties should already have been accomplished. These include:

1. A Site Enginering Study This study would have been initiated by a site survey to determine all the physical and environmental constraints of the installation. The engineering study ensures that the performance of the data link can be met and specifies the details of the installation, i.e. the location of the Inter-

face Panel, the mount/mast for the Access Unit and its location, identification of the power source, length of the System Cable, length of the wireless link, far end Access Unit location, etc. 2. Installation of the Rooftop Mast for the Access Unit A suitable mast, 2.5 to 4.0 O.D., of sufficient height to meet the Access Unit mounting height requirement specified in the engineering study must have been installed. This mast must be braced or ballasted to survive high winds and grounded to the rooftop lightning protection system in accordance with NEC or local regula-

tions. 3. Installation of the System Cable This installation must have been completed in conformance with building requirements and governing codes by trained and licensed installers. Telaxis P/N 50315 745 REV. ED1 5 Getting Started (cont.) 4. Installation of the Interface Panel The Interface Panel should be either rack or wall mounted in a suitable location in the Equipment Room to allow easy connection to the ADM and the dc power source. 5. Review of Installation Details The installer should review the engineering study to assure an understanding of all the installation requirements. This includes the Access Unit type ( A or B), mounting height, LOS (Line-Of-Site) direction to the far end of the link, antenna polarization (Horizontal or Vertical) and ADM data source identification.

Carry the unit by the handle provided Avoid impact or shock to the unit, especially to the antenna radome When handling/moving the unit, always have protective caps on conectors (2) 1. Position the Access Unit to the Mount, orienting the Access Unit for Horizontal

(handle horizontal) or Vertical polarization (or handle vertical), as specified in the System Engineering Analysis. IMPORTANT:

Polarization of the near end and far end Access Units must be the same. The System Engineering Analysis designates Horizontal or Veritcal polarization. Each link is comprised of two Access Units, one type A and one type B, as designated by the last digit of its model number (example AU2006-A is type A). Install the type A and type B Access Units in the near end or far end, as specified in the System Engineering Analysis. 2. Attach using 3 M10 x 35 Flat Head bolts thru the 3 holes provided in the Mount. Apply LocktiteTM to threads of bolts. Use the 5mm Allen key provided to torque bolts to 22 N-m (16.2 lb-ft).

ED1 13 5 Make Final LOS Adjustment to FiberLeap Access Unit The purpose of this step is to adjust the LOS (Line of Sight) of the Access Unit to maximize the signal level. During this step, the second FiberLeap Access Unit at the far end of the link must also be installed and powered ON. A continuous TX data signal must also be present at the far end link. For purposes of Final LOS alignment and signal optimization, a BERT (Bit Error Rate Tester) or an ADM with BERT capability may be used to feed a SONET test pattern into the OC DATA, TX input connector of the FiberLeap Interface Panel at the far end. Refer to Figure 7 unless otherwise noted. 1. Connect a dc voltmeter to the BNC connector on the rear of the Access Unit using a BNC-to-test lead adapter. The voltmeter should read a dc voltage of between 0.5 to 5.0 volts (see Figure 10). 2. Slacken the 2 azimuth clamp bolts on the Mount 1/2 turn. Using the Azimuth Adjustment Bolt, adjust the azimuth LOS until the reading on the voltmeter is at a maximum. It is advised that, in order to ensure the true maximum, you should adjust through the maximum (peak voltage) until the voltage clearly begins to drop and then adjust back until the maximum is attained again (see Figure 11). 3. Tighten the 2 Azimuth clamp bolts on the Mount while observing the voltmeter reading to ensure the azimuth alignment does not change while tightening. Tighten bolts to 22 N-m (16.2 lb-ft). 4. Slacken the 4 Elevation clamp bolts on the Mount 1/2 turn. Using the Elevation Adjustment Bolt, adjust the elevation LOS until the reading on the voltmeter is at a maximum. It is advised that, in order to ensure the true maximum, you should adjust through the maximum until the voltage clearly begins to drop and then adjust back until the maximum is attained again. 5. Tighten the 4 Elevation clamp bolts on the Mount while observing the voltmeter reading to ensure the elevation alignment does not change. Tighten Nuts to 22 N-m (16.2 lb-ft). 6. Repeat steps 1 through 5 (above) to guarantee optimum alignment for maximum signal strength.

-2 0 2 AZ, EL Position (degrees) 6 Test the Link Prior to placing link in service for network traffic, the link should be tested for BER using standard procedures for fiber optic cables. The Installation Record (see page 17) and Warranty Registration should be completed with pertinent installation information. Telaxis P/N 50315 745 REV. ED1 15 5 Operation Operation of a FiberLeap link is quite simple. There are no user controls or adjustments possible except for the ON/OFF switches on the Interface Panels at each end of the link, and aiming the LOS (alignment) of the Access Units. Once turned ON, the units are fully operational. If SONET data is being supplied by the network to the OC TX connector at the Interface Panel, the Access Unit will transmit that data to the link far end Access Unit. Absence of a valid SONET signal will mute the transmitter. In the event of network alarms, refer to the FiberLeap Troubleshooting Guide. Please note that any attempt to open or modify a FiberLeap Access Unit will void the warranty. 6 Inspection and Maintenance Routine Inspection of the FiberLeap Access Unit and exterior portions of the Cables should be performed at least once per year to check for loose hardware, damage, corrosion or other disturbance to the installed hardware. Any damage, corrosion or conditions not conforming to the original installation should be corrected immediately. Replacement of an Access Unit, Interface Panel or Cable, or any realignment of either of the two FiberLeap Access Units requires a retest for BER (see pages 14-15). Telaxis P/N 50315 745 REV.
