Document No. D-L2500-001 L-2500 Users Manual 06/15/05 Version Draft 2 10 SECTION 2 Installation Procedures 2.1 Introduction This Users Manual provides basic instructions on the assembly, alignment and verification of Loea RF systems. It also outlines recommended tools and processes to use to working with Loea technology. Reading this section in detail is highly recommended prior to starting any work on site. Only Loea Trained and Certified installers should perform installation services on a Loea RF product. Please note that every area of the country has its own codes of safety and construction. Installations like this must comply with these codes. It is the users responsibility to understand what codes apply and to ensure that the installation conforms to these codes. 2.2 Standard Minimum Toolkit Loea sells standard toolkits to its trained and certified installers. Should an installer wish to acquire tools independently, the following list is the minimum recommended set: i) Digital Multimeter ii) Lineman's Tool iii) Two-way Radio iv) Spotlight Lantern v) Signal Mirror, 3x5” vi) Diagonal Cutter, Large vii) 3 in 1 screw driver viii) Wire strippers ix) Channel Locks x) 3/8” Nylon Rope, 100’ xi) Ratchet, ½” Drive xii) Deep well socket, 1-1/8” xiii) Deep well socket, 15/16” xiv) Deep well socket, ¾” xv) Deep well socket, 9/16” xvi) Long Hex Key, 5/8” xvii) Hex Ball driver, 3/16” xviii) Hex Ball driver, 5/32” xix) Adjustable wrench, 8” xx) Adjustable wrench, 12” xxi) Combination wrench, 15/16” xxii) Combination wrench, ¾” xxiii) Combination wrench, 9/16” xxiv) Thin Pattern wrench, 1-3/4” xxv) Thin Pattern wrench, 1-1/8” 2.3 Pre-installation requirements Before the installation of a Loea link, certain steps must be taken to ensure that the installation will be successful. A. Site Survey: During a site survey a trained and certified Loea installer can assess the environment of the installation, ensure that the physical conditions of the site are appropriate, indicate where building connections need to be available and ensure that Line of Sight (LOS) exists between the two end points.
Document No. D-L2500-001 L-2500 Users Manual 06/15/05 Version Draft 2 11 B. FCC Part 101 License: Loea’s band of operation is protected by FCC rules. Therefore, each path must be submitted for approval to a path coordinator. Loea’s Services unit can do this for the user or the user can file independently. a) Loea to obtain License: Indicate to the individual performing the site survey. He will collect GPS information and file for a site license immediately. Loea holds a Nation-wide approval from the FCC & NTIA to deploy in this band. b) User to obtain License: If the user wishes to hold his own license, a nationwide approval must first be gained from the FCC. This is a relatively simple process that is done online and takes about 30 days. Please contact Loea directly for assistance with this. Once the nationwide license is obtained, then the GPS information can be submitted to one of the path coordinators approved for this band. Path approval is generally completed in just a few days. C. Installation of Mast and Demarcation: A mast of 4in O.D. must be installed at a position on the roof and specific height as specified in the Site Survey. Non-compliance will violate the FCC license. To facilitate connection to the buildings network, fiber for communications, 115V AC conditioned power and optional Ethernet for monitoring are required in a demarcation box per the specifications in this manual and specifically as defined in the Site Survey. D. Bench Test: Loea recommends that at a minimum, the transceivers are tested on site prior to installation. To do this separate the transceivers by a minimum of 5 feet, point them towards each other and verify AGC levels and BER performance as described in sections 2.6, 2.7 and 2.8. If possible, a complete end to end test is recommended with switching and/or encryption devices used as well. While the Loea transceiver is generally a plug and play device, it is advisable to do this to avoid timely de-bugging in the field. E. System Verification and Operational Test (SVOT): Upon physical installation completion, a snap shot of the transceiver should be taken to verify that the transceiver is fully functional and that the environmental conditions are recorded. This will assist Loea customer service and help desk personnel assess problems should a link fail to operate. See Appendix B for a copy of these forms. 2.4 Construction of Mast and Steering System 2.4.1 Assemble azimuth and elevation control arms Requires: two MRP-2003 Azimuth arms (5), one MRP-2005/1 Gross adjustment nut (2), one MRP-2005/2 Fine adjustment nut (4), one MRP-2007 Elevation adjustment nut (6), two RH threaded ball joint ends (3), one LH threaded ball joint end (1), ¾”-10 Threaded rod (7), and one ¾” jam nut (8). Thread the Left Hand threaded ball joint (1) halfway into the Gross adjustment nut (2). Thread one Right Hand threaded ball joint (3) equally into the Fine adjustment nut (4). Thread each adjustment nut about halfway into an Azimuth arm (5).
Document No. D-L2500-001 L-2500 Users Manual 06/15/05 Version Draft 2 12 Thread the jam nut (8) and the course end (6a) of the Elevation adjustment nut (6) onto the one end of the ¾”-10 threaded rod (7) far enough to reach the hollow. Thread the ball joint (3) equally into the fine end of the adjustment nut (6b). 2.4.2 Assemble Antenna mount plate and control arms Requires: one MRP-2006 Mount plate (9), one MRP-2008 pillow block (10), four ½” Hardware Assemblies (11) consisting of [½”- 13 x 1-3/4” bolt, hex nut, lock washer, flat washer], and three ¼”-20 socket head cap screws (12). Position the Mount plate (9) so the offset tab is on the lower right while assembled. Locate the three ¼”-20 threaded holes on the tab and fasten the pillow block (10) to the plate with the socket head cap screws (12). The application of Lock-Tite™ or an equivalent compound during this step is recommended.
Document No. D-L2500-001 L-2500 Users Manual 06/15/05 Version Draft 2 13 Position each Azimuth arm with adjustment controls up, on the backside of the plate capturing the ½” through holes of the upper and lower tabs on each side of the Mount plate. Fasten the arms to the plate using the ½” Hardware Assemblies (11). 2.4.3 Assemble Antenna mount plate and Pole plate Requires: one MRP-2002 Pole plate (13), one MRP-2010 Elevation Lock nut (14), one ball joint bearing (15), three ¾”-10 socket head cap screws (16), and one ¾” jam nut (8). Position the Pole plate (13) so that the bearing block for the Elevation control arm is on the lower left while assembled. Securely brace the pole plate and gently tap the ball joint bearing (15) into the block with a bearing drift or large socket. Orient the two plates so that the ball joint ends of the Azimuth control arms line up with the ¾” tapped holes on each end of the pole plate cross beam. Next, fasten the ball joint ends to the cross beam of the pole plate by inserting the ¾” socket head screws (16) through the ball joint and thread into the tapped ends. Tighten until snug, do not over tighten or torque the ball joint screws. Thread the jam nut (8) halfway up the free end of the elevation (threaded rod) arm. Slide the free end through the ball joint bearing (15) of the pole plate. Rotate the antenna mount plate so the ball joint end attached to other end of the Elevation arm lines up with the ¾” tapped hole in the adjacent side of the pillow block. Secure the Elevation arm to the pillow block in the same manner as the Azimuth arms. Thread the Elevation lock nut (14) onto the free end of the Elevation arm. Adjust the Elevation lock nut and the ¾” jam nut (8) as needed to minimize movement of the antenna mount plate during final assembly.
Document No. D-L2500-001 L-2500 Users Manual 06/15/05 Version Draft 2 14 2.4.4 Attach assembly to Mast, attach antenna Requires: two U-Bolt Assemblies (17) consisting of [one 4.5” diameter, ½”-13 U-bolts, two hex nuts, two lock washers], four 3/8”-16 bolts and flat washers (18), and Antenna (19) Lifting the steering assembly from the front, press the pole plate against the mast using the parallel runners on the backside to steady the assembly while the two U-bolt assemblies (17) are installed. Once the steering system is shifted into the desired position the plate’s runners will bind to the mast as the U-bolts are tightened so as to prevent the mount from inadvertently slipping. Once the steering assembly is secured to the mast, locate the four 3/8” through holes correlating with the four threaded holes located on the backside of the antenna. Position the antenna (19) onto the mount plate in relation to the most accessible placement of the optical alignment scope. Secure the antenna to the mount using the 3/8” bolts and flat washers (18). Although the steering system can accommodate course adjustments, the mount may need to shift beyond the range of the Azimuth arms. The U-bolts can always be loosened enough to permit a slightly greater rotation to correct such alignment issues.
Document No. D-L2500-001 L-2500 Users Manual 06/15/05 Version Draft 2 15 2.4.5 Attach transceiver to mounting and steering system Requires: four 1/4”-20 bolts, and lock washers (20) Once the steering assembly with antenna is secured to the mast per 2.4.4 above, lift the transceiver and pass it through opening ‘A’ in the steering assembly aligning the four 3/8” through holes on the transceiver (21) with the four threaded holes (22) located on the Mount plate. NOTE: Ensure the transceiver housing is positioned such that the cooling fins on the housing are vertical with respect to the mounting base. For sites requiring vertical polarization rotate the housing so that the cooling fins are horizontal with respect to the mounting base. Secure the transceiver to the Mount plate using the 1/4”-20 bolts, and lock washers (20) as shown below. Configuration shown is for horizontal polarization. 2.5 Alignment Techniques The alignment process for a Loea link is performed manually. The Loea mounting and steering system has vertical (V) and horizontal (H) tuning bars along with a scope mounted on the side of the antenna for fine alignment. General coarse alignment is achieved by first using the scope to obtain visual alignment of the system. The U-bolts (U) are loosened slightly to enable rotation of the transceiver and antenna around the pole. If the links are separated beyond the magnification of the scope, the use of a reflecting device can be helpful during this coarse visual alignment. A
Document No. D-L2500-001 L-2500 Users Manual 06/15/05 Version Draft 2 16 _________________________________________________ Once coarse visual alignment is complete, use the AGC reading (section 2.6) to tune in the radio link. This is best done by sweeping the dishes over the area of a small rectangle, tuning one dish at a time using the fine adjustment tuning bars (V) and (H) until each transceiver has the appropriate AGC reading. NOTE: Make sure that at each end of the link the transceiver is not ‘peaked’ on its side-lobe. Observing the AGC voltage and making sure there are two smaller voltage peaks on either side of the main peak can avoid this. Do this when sweeping across a small triangle in the direction of the opposite end. H V U Peak gain Side-lobes ScopeVisual alignment
Document No. D-L2500-001 L-2500 Users Manual 06/15/05 Version Draft 2 17 2.6 Interfacing to AGC The AGC voltage is a measure of received signal strength, typically used to assess alignment. To measure the AGC voltage, remove the service compartment cover (G) of the Loea transceiver. In the service compartment is a BNC connector (J) with two receptacles for Digital Multi-meter probe tips. Also in the service compartment is a chart (H) indicating the appropriate and acceptable range of AGC for your transceiver. By fine-tuning the alignment, try to get the AGC voltage within a few dB’s of the path loss specified in your final proposal by Loea. This is a good measure that your link is properly aligned. 2.7 Verification of BER Verification of Bit Error Rate (BER) is achieved by using a fiber optic line tester to validate the Loea Wireless Fiber link. Typical Fiber line testers can verify the protocol (Gigabit, Ethernet, IP or OC-12 SONET), bandwidth, optical signal quality in addition to BER ensuring a true fiber optic replacement. 2.8 Final Site Verification See document “SVOT” in appendix “XX”

The Demarcation Box allows costs and setup to be predictable and controlled from the Demarcation Box to the Data Link. The Demarcation Box will be pre-installed no more than 15’ from the transceivers and shall provide, as a minimum, the following connections: • 98-132 VAC, 60 Hz • Fiber-optic connection, dual SC Additional Demarcation connections that may simplify the link installation and operation are: • RJ-45 - CAT5 10/100baseT Ethernet connection to the transceiver’s system monitoring port. • RS-232 - Serial interface to the transceivers on-board CPU 3.1.1 Enclosure Mounting Options • Holes and cutouts can be provided in enclosures and panels. • All six sides of an enclosure can have holes and cutouts. • Some areas on the enclosure (e.g. close to a corner) cannot have holes and cutouts. • If a hole or cutout interferes with an existing grounding stud, the grounding stud will be moved to the closest possible location. • All holes and cutouts must be filled with a component or accessory with the same NEMA/UL rating as the enclosure in order to maintain the overall NEMA/UL integrity of the enclosure. EMC integrity can be maintained by installing EMC shielded components.

Document No. D-L2500-001 L-2500 Users Manual 06/15/05 Version Draft 2 19 3.2 Basic Information on Loea Interface The Loea transceiver operates at the Physical Layer (Layer 1) of the OSI network stack. The transceiver is protocol agnostic and to the view of the IT professional or systems integrator, Loea’s Virtual Fiber transceiver will look and feel just like traditional Fiber optic cable. Loea’s transceiver is also 100% self-contained and will consume no space in the IT locker rack system. The transceiver has two mandatory, one optional and one service connection as follows: 1.) Optical Signal interface (A): For Ethernet standard, Loea will use Multimode 852nm Fiber and for the OC-X standard, Loea will use Single-mode 1310nm fiber. Optical connections are made by passing the incoming fiber optic cable through the cable entry gland (F) and making the connection to the signal interface (A). 2.) AC Power interface (B): The Loea transceiver in standard configuration requires a nominal 115V AC connection with transient conditioning via an Un-interruptible Power Supply (UPS). The typical UPS to be used with the transceiver has an operational AC input range of 98 - 132VAC and provides battery back up to offer operation in the event of power loss. The system only requires 30W and will operate from a battery backup for some time. A Loea engineer can recommend a solution based upon customer requirements. The AC power connection to the transceiver is made by passing the incoming AC power cable (D) from the UPS through the cable entry gland (F) and then making the connection to the AC receptacle (B). 3.) Optional connection for Link monitoring (C): Because the transceiver can be viewed as a network element, there is a standard RJ-45 (C) connection for a SSL (Secure) and SNMP.v1 connection option for NOC (or Loea’s LOC) interface. SNMP.v3 is under development and expected later in 2004. Other options here include Cellular and dial up options. 4.) Serial interface (E): A local RS-232 interface is available for local troubleshooting and status information retrieval.
Document No. D-L2500-001 L-2500 Users Manual 06/15/05 Version Draft 2 20 Note: The transceivers on board computers allow customers access to link status only. The hooks are out of band and transceiver performance cannot be remotely altered. Because the Loea system is Layer 1 and protocol agnostic, it will interoperate with most commercial off the shelf (COTS) switches, routers and encryption devices. The systems weather availability is also beneficial from the IT professional perspective in that a Loea RF system operates at ultra high BER (10-12) until the rare event of a link becoming weather disabled, will look like a cut fiber. Additionally, Loea links re-clock each bit before hand-off to COTS devices. This provides a sharp signal edge with little jitter.
