TM GE60 Installation Manual 580-00505, rev 0.4 8 of 30 PRELIMINARY 2 Site Planning 2.1 General Before the start of an installation a survey should be conducted of the proposed area of the site(s). The survey personnel should be fully familiar with the details required to install the GE60 radio system. 2.2 Equipment Checklist The survey team will need the following equipment: • Binoculars • GPS Navigation Device • Tape Measure • Site Survey Report Form 2.3 Line of Sight (LOS) The GE60 Wireless Gigabit Ethernet link requires Line-of-Sight for proper operation. Fortunately, the links are relatively short and obstructions in the path can easily be identified. Binoculars can ease viewing in poor light conditions. The planning should include an investigation into future building plans that could block the LOS path, and other long-term incremental obstructions such as trees. Intermittent obstructions such as aircraft at a nearby airport should also be considered. The minimum required clearance from obstacles is 60% of the first Fresnel zone. Fresnel zones are a series of concentric ellipsoid areas surrounding the straight-line path between two antennas. The first Fresnel zone is the area containing every point of which the distance from the transmitter to any reflection point on the area and on to the receiver is half a wavelength longer than the path of the direct signal. The radius of the Fresnel zone is greatest at midpoint in the signal path. )1(005.0)(ρρ−∗∗∗= DmetersaranceMinimumCle where, D = Path distance in meters ρ = Distance from antenna as a percentage of path distance

This measurement can be performed using the Latitude and Longitude readings from a Global Positioning System (GPS) device, which is placed near the proposed locations of the antennas, or using a range finder device. Table 2-2 below lists the maximum link distance with respect to desired availability and ITU rain zone (ITU-R Recommendation PN.837).

TM GE60 Installation Manual 580-00505, rev 0.4 11 of 30 PRELIMINARY 2.5 Antenna Location The optimum location for the antennas must be determined. The ideal location should provide for ease of erecting and mounting the antenna, as well as unimpeded Line-Of-Site (LOS) to the other site. The following factors should be taken into account: • Type of mounting—wall or pole • Length of cable runs • Grounding connection points • Obstructions • Accessibility 2.6 Cabling The installation site should be inspected to determine the run paths for the fiber cable and power cable from the radio equipment to the termination point. Locations for roof penetration should be identified. The routing and securing of all cables should conform to all applicable codes and requirements. Depending on the likelihood of damage due to foot traffic or equipment movement, cabling conduit may be required. The maximum cable run length as specified for the equipment being installed must not be exceeded. Our radio requires an “LC” type connector on the multi-mode fiber to properly connect the fiber to the radio. Single-mode fiber is not a current option supported by the radio. The type of fiber connector (typically either LC or “SC”) required on the other end of the fiber that connects to the applicable Gigabit Ethernet switch, router, or bridge will depend upon the interface on your applicable networking equipment. The GE60 radio includes a 100-240 VAC power adaptor that converts the AC voltage from the standard electrical outlet in the wall to DC voltage. Our radio requires a minimum of 13.5 VDC (24.0 VDC maximum) up the power cable to the radio to function properly. When planning the cable run from indoor mounted AC power adaptor to the radio unit, it is critical to select the cable AWG to ensure adequate voltage at the radio.

Indicates that serious damage to the equipment can result if the user does not comply with the given instruction. A WARNING statement will describe the potential hazard, its possible consequences, and the steps to perform to avoid serious equipment damage. Proper grounding of the outdoor equipment reduces electromagnetic interference, provides lightning protection, and protects against electrical discharge. The source and connection points for the building-to-earth ground in the vicinity of the antenna location should be determined. A 5’ (1.5m) copper cable is provided with each radio for a ground cable to allow the radio to be grounded to the applicable pole or to the mount in the event a pole is not used for the installation. The pole or mount, as applicable, will need to be connected to the building ground. In addition to grounding the equipment, local building codes may require the DC electrical cable to be protected from lightning strikes. In the event your local city or county requires such a device you may use a Polyphaser circuit protector model # IS-PSP-24, manufactured by Polyphaser Corporation (or equivalent model from another manufacturer). The Polyphaser device is available from the following companies: TESSCO MD & NV 800-472-7373 Talley Communication CA 800-949-7099 Hutton Communication TX 877-648-8866 Primus IL 800-435-1636 TEDI FL 800-729-8334 2.8 Environmental The structure to which the equipment will be mounted should be adequate to bear all wind and other weather conditions. The environmental conditions at the location must conform to the operating environment specified for the equipment.

Install 4 mounting bolts in the wall at the desired location using the template provided (see Figure 3-4 below). The bolts (normally ⅜-16) should extend 0.8 to 3.0 inches (2cm to 7.5cm) from the wall and be strong enough to secure the radio to the wall under foreseeable environmental conditions. The environmental conditions may include, but not limited to, wind, rain, ice, etc. Depending on the wall material the mount is being attached to, a different size bolt may be appropriate. In this case, bolts up to ¾ inch in diameter may be used. 2. Secure the mount to the bolts using the appropriate sized nuts, lock washers, and flat washers for the bolts used to mount the bracket. Figure 3-1: Mount in ‘Wall Mount’ Configuration
TM GE60 Installation Manual 580-00505, rev 0.4 17 of 30 PRELIMINARY 3. Attach the radio yoke to the mount, with brass shim in-between, using 2 each of the supplied ⅜-16 x ¾ bolts, ⅜ lock washers, and ⅜ flat washers. Tighten the bolts just enough that the yoke can move back and forth without binding. Pole Mounting The optional pole mount kit can be used to secure the mount a pole with diameters of 2.0 to 4.5 inches (5cm to 11cm). 1. Attach two of the pole clamps to the mounting bracket using 4 each ⅜-16 x ¾ bolts, ⅜ lock washers, and ⅜ flat washers. Attach the threaded rods to the pole clamps using 8 ⅜-16 nuts and 4 each ⅜ lock washers and ⅜ flat washers. Refer to Figure 3-2. 2.

TM GE60 Installation Manual 580-00505, rev 0.4 20 of 30 PRELIMINARY 3.6 Radio Installation 1. Remove the up/down adjustment bolts from the radio. Place the radio in the yoke—the two up/down pivot bolts should rest in the U’s cut in the yoke. Note that when the radio comes from the factory, the mounting plates are in the “vertical polarization” position, that is, the diamond marking on the radio (see insert below) on the front of the radio housing is to the right when viewed from the front. For “horizontal polarization,” the mounting plates should be moved so that the diamond is at the top when viewed from the front. Polarization Diamond orientations: Horizontal (Left) and Vertical (Right) See Figure 3.7 for further explanation and visual image of Horizontal vs Vertical polarization. CAUTION! Indicates that equipment damage, process failure, and/or loss of data can result if the user does not comply with the following given instruction. A CAUTION statement will describe the potential hazard, its possible consequences, and the steps to perform to avoid equipment damage, process failure, and/or loss of data. It is critically important during installation to ensure the radios on each side of the link are in the same polarization (i.e., Horizontal-Horizontal or Vertical-Vertical). A link that has a radio on one side of the link set in the Horizontal polarization and the other side of the link set in the Vertical polarization will not operate properly. Further, it is also critically important that a “High-Band” radio is paired with a “Low-Band” radio to ensure the system will operate properly. Prior to installation check each radio to verify one is a High-Band and the other is a Low-Band version. The label on the side of the radio will indicate whether it is a High-Band or Low-Band version.

Tighten the up/down pivot bolts enough such that the finger cam is behind the tab at the front of the yoke. Turn the finger cam clockwise until tight. With the cam tightened, the pivot bolt is prevented from any front/back movement. Figure 3-6: Detail of Up/Down Pivot & Adjustment Bolts and Finger Cam
TM GE60 Installation Manual 580-00505, rev 0.4 22 of 30 PRELIMINARY 3.7 Cable Installation Fiber Cabling 1. Install a duplex multi-mode fiber from the radio to the network termination equipment (switch or router with 1000Base-SX port). The connectors on the radio end of fiber require LC connectors; the connectors on the switch/router end should mate to the network equipment. 2. Connect fibers at the network equipment. Power Cabling 1. Select indoor location, with easy cable routing to the radio, for the AC power adaptor. Normally it is convenient, but not required, to place the adaptor near the network termination equipment. 2. Select the appropriate wire gauge based on the estimated cable length required—AC adaptor location to radio, see Table 2-4. 3. Install the DC power cable and attach to the AC adaptor using the supplied terminal block. Do not plug-in the AC adaptor at this time. Figure 3-7: Front view of fiber and power cable installed (Note: Radio is shown in the Horizontal polarization as the “diamond” is on the top)

Both the cables have been looped around the inside of the enclosure to minimize tension on the cables when connected to the radio. Ground Cabling 1. Attach the lug of the copper ground cable provided with the radio to one of the two #8 holes at the bottom of the radio using a #8-32 bolt, #8 lock washer and #8 flat washers. 2. Connect other end of the ground cable to a nearby grounding location.
TM GE60 Installation Manual 580-00505, rev 0.4 24 of 30 PRELIMINARY 3.8 Visual Alignment 1. Tighten mounting bolts just enough to allow radio to pivot up/down and right/left with minimal effort. 2. Tilt the radio so that it is roughly point towards the other end of the link. 3. Insert the Visual Alignment Tool (VAT) into one of the 4 holes in the front (antenna) face of the RADIO. The VAT is used to precisely orient (align) the radio in the correct direction. Select the hole that allows the most convenient viewing of the other end of link. The best viewing is achieved with your eye ~13 inches (~33cm) from the VAT mirror. The radio is aimed at the point tangent to the top of the red indicator when all three indicators (green/red/green) are in a line with equal gaps between the indicators. Figure 3-9: View of VAT installed in the right hand side-mounting hole 4. Tilt the radio up/down and right/left so that radio at the other end of the link is positioned at the top of the red indicator. See example below.

Tighten the left/right adjustment bolt enough to prevent accidental movement of the radio. This is the bolt on the mount bracket, closest to the wall or pole. Verify the radio has not moved in left/right direction. As this bolt is tightened up/down movement of the radio may occur due to the seating the mounting bracken and radio yoke seat together. 6. Re-adjust the radio up/down, as necessary, due to the tightening of the mounting bracket. Tighten the lower bolts (below the up/down pivot bolts) on the radio yoke, being careful not disturb the up/down pointing of the radio. Once the lower bolts are tight, tighten the up/down pivot bolts. 7. Connect DC power to the radio, check that the Power LED is lit. If the Power LED is not lit, use voltmeter to verify correct voltage and polarity at radio. 8. Connect Tx & Rx fibers to the radio and check that the Fiber LED is lit. If the Fiber LED is not lit, swap the position of the Tx & Rx fibers and recheck. (NOTE: In the event a fiber loopback cable is used on one of the radios in order to test the link, the Fiber LED will not light until the link is aligned and operating) 9. Repeat steps 1 through 8 on other side of link.
TM GE60 Installation Manual 580-00505, rev 0.4 26 of 30 PRELIMINARY 10. Remove the plastic cover on the back of the radio that is secured with a cap bolt. Look to see that the “Link Up” LED is lit. This LED is lit when the two radios are aligned and passing data to one another. The link may still need be optimized via additional movement of the radio up and down and left and right; however, there is no need to proceed to the “Fine Alignment” or “BER voltage” steps detailed below unless this LED is lit. 11. If desired, perform optional Fine Alignment (Section 3.9) on both sides of the link. 12. Check the BER voltage. 3.3VDC indicates error free link. Note--alignment must be completed on both sides of the link and “Link Up” LED must be lit solid green before valid voltage readings can be made. Figure 3-10: Proper placement of voltmeter cables to check Pre-FEC BER Note: Black cable is connected to ground and red cable is connected to Pre-FEC BER pin 12. Securely tighten all mounting bolts.
TM GE60 Installation Manual 580-00505, rev 0.4 27 of 30 PRELIMINARY 3.9 Fine Alignment -- Optional The fine alignment procedure uses Receive Signal Strength Indication (RSSI) voltage generated by the radio’s receiver. Since this voltage reacts to the power of the received signal, it is not influenced by the machining/manufacturing tolerances seen with mechanical parts. While procedure can yield an improvement of up to 2 dB in Link Budget when performed on both sides of the link, only those links with path lengths near the maximum length will see any benefits. 1. Attach voltmeter to the RSSI voltage pins. Note the RSSI voltage. The voltage may be fluctuating; in this case, note the maximum value seen. Figure 3-11: Proper placement of voltmeter cables to check RSSI Note: Black cable is connected to ground and red cable is connected to RSSI pin 2. Using care not to disturb the pointing of the radio, loosen the bolts tightened in steps 5 & 6 of the Visual Alignment procedure (Section 3.8) so that the radio may be tilted up/down and left/right.
TM GE60 Installation Manual 580-00505, rev 0.4 28 of 30 PRELIMINARY 3. Tilt the radio left and right until the maximum reading is achieved on the voltmeter. Tighten the left/right adjustment bolt to prevent movement in this axis. 4. Tilt the radio up and down until the maximum reading is achieved on the voltmeter. Tighten the up/down adjustment bolts to prevent movement further movement.
TM GE60 Installation Manual 580-00505, rev 0.4 29 of 30 PRELIMINARY 4 Operation The GE60 has been designed such that it requires no user configuration. During normal operation, the following conditions should exist at the radio: 1 The power LED should be lit—solid green; 2 The fiber LED should be lit—solid green; 3 The Link Up LED should be lit—solid green; and 4 The Pre-FEC BER voltage should be 3.3v, although occasional dips in voltage are acceptable. Figure 4-1: Link Up, Fiber and Pwr (Power) LED’s indicating link is up and operating The GE60 radio itself does not require periodic maintenance. However, each end of the link should be periodically inspected for visible damage or excessive accumulation of dirt.
