Installation Requirements

7.1.1 Component Location Requirements

7.1.2 Cable and Connector Requirements

NOTE: Faulty cabling is the cause of a vast majority of problems. All CATV cable

should be tested to TIA-570-B specifications.

Fusion components are intended to be installed in indoor locations only.

If outdoor installation is desired, such as a parking garage, the Fusion components must be installed in the appropriate environmental enclosures.

Fusion equipment operates over the following:

• CATV 75 Ohm cable with F connectors

• Single-mode fiber (SMF) or multi-mode (MMF) cable with SC/APC fiber connectors throughout the fiber network, including fiber distribution panels

These cables are widely-used, industry standards for the cable TV industry. The regulations and guidelines for Fusion cable installation are identical to those specified by the TIA/EIA 568-B standard and the TIA/EIA/570-A standards.

LGC Wireless recommends solid copper center conductor, plenum-rated CATV cable and connectors for conformity to building codes, standards, and to ensure stated performance of maximum distance and RF specifications.

CommScope 2065V cable or equivalent is required for RG-59.

CommScope 2279V cable or equivalent is required for RG-6.

CommScope 2293K cable may also be used for RG-11.

NOTE: Refer to Appendix A for more information related to 75 Ohm CATV.

LGC Wireless recommends connectors with fixed centerpins to ensure proper seating and to eliminate oxidation, which occurs with bare center conductors. Recommended connectors are as follows:

CANARE Connectors

• FP-C4F for commScope 2065V cable

• FP-C55A for CommScope 2279V cable

• FP-C71A for CommScope 2293K cable

CONFIDENTIAL

Safety Precautions

The internal power supplies have internal fuses that are not user replaceable. Consider the worst-case power consumption shown on the product labels when provisioning the equipment’s AC power source and distribution.

Verify that the Hub is grounded properly using the AC power cord third wire ground.

NOTE: Be careful with the mechanical loading of the rack mounted hub. Mount the equipment in the rack in such a way that a hazardous condition, due to uneven mechanical loading, does not result,.

7.2.2 General Safety Precautions

The following precautions apply to LGC Wireless products:

• The units have no user-serviceable parts. Faulty or failed units are fully replaceable through LGC Wireless. Please contact us at:

1-800-530-9960 (U.S. only) +1-408-952-2400 (International)

• Although modeled after an Ethernet/LAN architecture and connectivity, the units are not intended to connect to Ethernet data hubs, routers, cards, or other similar data equipment.

• When you connect the fiber optic cable, take the same precaution as if installing Ethernet network equipment. All optical fiber SC/APC connectors should be cleaned according to the cable manufacturer’s instructions.

• When you connect a radiating antenna to an RAU, firmly hand-tighten the N connector – DO NOT over-tighten the connector.

WARNING: To reduce the risk of fire or electric shock, do not expose this equipment to rain or moisture. The components are intended for indoor use only. Do not install the RAU outdoors. Do not connect an RAU to an antenna that is located outdoors where it could be subject to lightning strikes, power crosses, or wind.

• The Expansion Hub and RAU units are designed for intra-building cabling only. Outdoor routing of any cabling to these units shall not exceed 140 feet.

NOTE: Outdoor cables farther than 140 feet must be installed with proper lightning protection.

Connecting the Fiber Cables to the Main Hub

Considerations:

• Before connecting the fiber cables, confirm that their optical loss does not exceed the 3 dB optical budget.

• If you are using fiber distribution panels, confirm that the total optical loss of fiber cable, from the Main Hub through distribution panels and patch cords to the Expansion Hub, does not exceed the optical budget.

• Make sure the fiber cable’s connectors are SC/APC (angle-polished). Using any other connector type will result in degraded system performance and may damage the equipment. (You can use an SC/APC pigtail if the fiber cable’s connectors are not SC/APC. Refer to“Fusion Splicing of Fiber and Pigtail” on page 7-37. Or, you can change the fiber’s connector to SC/APC.)

NOTE: Observe all Fiber Port Safety Precautions listed in Section 7.2.3 on page 7-5.

Fusion Installation Procedures

To clean the fiber ports:

You can clean the Hub’s fiber ports using canned compressed air or isopropyl alcohol and foam tipped swabs.

Considerations:

• If using compressed air:

• The air must be free of dust, water, and oil.

• Hold the can level during use.

• If using isopropyl alcohol and foam tipped swabs:

• Use only 98% pure or more alcohol

Procedure using compressed air:

Remove the port’s dust cap.

Spray the compressed air away from the unit for a few seconds to clean out the nozzle and then blow dust particles out of each fiber port.

Procedure using isopropyl alcohol:

Remove the connector’s dust cap.

Dip a 2.5mm lint-free, foam-tipped swab in isopropyl alcohol and slowly insert the tip into the connector.

Gently twist the swab to clean the port.

Insert a dry swab into the port to dry it.

Additionally, you can use compressed air after the alcohol has completely evaporated.

To clean the fiber ends:

Be sure that the fiber cable’s SC/APC connectors are clean and free of dust and oils. You need lint-free cloths, isopropyl alcohol, and compressed air

Moisten a lint-free cloth with isopropyl alcohol.

Gently wipe the fiber end with the moistened cloth.

Using a dry lint-free cloth, gently wipe the fiber end.

Spray the compressed air away from the connector for a few seconds to clean out the nozzle and then use it to completely dry the connector.

To test the fiber cables:

Perform cable testing and record the results. Test results are required for the final As-Built Document.

To connect the fiber cables:

The fiber cable is labeled with either 1 or 2, or is color-coded. In addition to these labels, you should add a code that identifies which port on the Main Hub is being

• If fiber distribution panels are used, confirm that the total optical loss of fiber cable, from the Main Hub through distribution panels and patch cords to the Expansion Hub, does not exceed the optical budget.

• Make sure the fiber cable’s connectors are SC/APC (angle-polished).Using any other connector type will result in degraded system performance and may damage the equipment. (You can use an SC/APC pigtail if the fiber cable’s connectors are not SC/APC, refer to “Fusion Splicing of Fiber and Pigtail” on page 7-37, or replace the connectors.)

NOTE: Observe all Fiber Port Safety Precautions listed in Section 7.2.3 on page 7-5.

To connect the fiber cables:

The fiber cable is labeled with either 1 or 2, or is color-coded. For proper connection between the Main Hub ports and the Expansion Hub ports, refer to the numbering or color-coded connections you recorded when installing the Main Hub(s).

7.4.3 Installing RAUs

CAUTION: Install RAUs in indoor locations only. Do not con-

nect an antenna that is installed in an outdoor location to an RAU. For outdoor installations, a protective enclosure is required.

Installing RAUs

Mount all RAUs in the locations marked on the floor plans.

Considerations:

• Install 800 iDEN and 850/1900 MHz RAUs so that their antennas will be separated by enough space to reduce signal interference between the 800 and 850 bands. Refer to Section , “800/850 MHz Isolation Requirements,” on page 7-27 for recommended distance between antennas.

• You can place the unit, without its fastening hardware, on a flat surface, such as a shelf, desk, cabinet, or any other horizontal surface that allows stable placement with the mounting base facing down to the mounting surface. For mounting to other locations (that is, walls, ceilings, poles) the RAU must be securely mounted using the 4 slotted mounting holes provided with #6 diameter fasteners. This method of mounting must securely hold a minimum of 7 lbs. load.

• Attach the RAU securely to a stationary object (that is, a wall, pole, or ceiling tile).

• For proper ventilation:

• Keep at least

• Do not stack RAUs on top of each other.

• Always mount the RAU with the solid face (containing the mounting holes) against the mounting surface.

clearance around the RAU to ensure proper venting.

D-620610-0-20 Rev A

Installing Passive Antennas

Refer to the manufacturer’s installation instructions to install passive antennas.

Location

Passive antennas are usually installed below the ceiling. If they are installed above the ceiling, you must consider the additional loss due to the ceiling material when estimating the antenna coverage area.

800/850 MHz Isolation Requirements

When deploying any RF system, give special attention to preventing receiver blocking or desensitization by out-of-band transmitters. Typically, sharp filters in the receiver front-end will reduce the interfering transmitters to tolerable levels. In select cases, the interferers may occupy a frequency band that is directly adjacent to the receiving band and cannot be adequately rejected by filtering. The only recourse in

these situations is to provide sufficient isolation by physically separating the interfering transmitters and receivers.

iDEN occupies spectrum at both 800 MHz and 900 MHz (Tx:806–825/Rx:851–870 and Tx:896–901/Rx:935–940), while the Cellular A and B carriers share a single 850 MHz block (Tx:869–894/Rx:824–849). The combination of these frequency bands, 800/900 MHz iDEN and 850 MHz Cellular, result in uplink (BTS receive) bands that are adjacent to downlink (BTS transmit) bands. Figure 7-9 depicts these nearly contiguous bands, with arrows indicating the interfering downlink and receiving uplink bands.

Figure 7-9

800/850 MHz Spectrum

Installation of an in-building distributed antenna system (DAS) to provide coverage for both 800/900 MHz iDEN and 850 MHz Cellular must account for these downlink-to-uplink interference issues and provide adequate isolation.

LGC offers the following guidelines toward achieving the proper amount of isolation when deploying LGC Wireless Unison DAS products.

Figure 7-10

Guideline for Unison RAU Antenna Placement

800 MHz iDEN Downlink and 850 MHz Cellular Uplink

A 2 MHz frequency gap (851 – 849 MHz) separates the 800 iDEN downlink and 850 Cellular uplink frequency bands. Because of this narrow spacing, 800 iDEN downlink intermodulation products may fall within the 850 Cellular uplink band. In addition, 800 iDEN downlink signals near the lower edge of the band at 851 MHz may

D-620610-0-20 Rev A

Fusion Installation Procedures

cause the 850 Cellular uplink automatic level control (ALC) circuitry in the RAU to engage and thereby reduce uplink gain.

To prevent either of these conditions, use the following guidelines:

• In-band 800 iDEN intermodulation products < -90dBm

• Lower frequency 800 iDEN signals < –30dBm for Fusion

Given a typical DAS configuration (4 iDEN carriers, omni-directional antennas, line of sight), these guidelines translate to an antenna spacing (d1) of 6 – 9 meters.

850 MHz Cellular Downlink and 900 MHz iDEN Uplink

A 2 MHz frequency gap (896 – 894 MHz) separates the 850 Cellular downlink and 900 iDEN uplink frequency bands. Because of this narrow spacing, 850 Cellular downlink intermodulation products may fall within the 900 iDEN uplink band. In addition, 850 Cellular downlink signals near the upper edge of the band at 894 MHz may cause the 900 iDEN uplink ALC to engage and thereby reduce uplink gain.

To prevent either of these conditions, use the following guidelines:

• In-band 850 Cellular intermodulation products < -90dBm

• Upper frequency 850 Cellular signals < –30dBm for Fusion

Given a typical DAS configuration (6 CDMA carriers for Fusion, omni-directional antennas, line of sight), these guidelines translate to an antenna spacing (d2) of 8-14 meters.

Spacing between RAUs FSN-8519-1 and FSN-809019-1 should be in a range of from 8 to 14 meters.

Connecting the Antenna to the RAU

Connect a passive multi-band antenna to the N connector on the RAU using coaxial cable with the least amount of loss possible.

CAUTION: Firmly hand-tighten the N connector – DO NOT over-tighten the connector.

Connecting the CATV Cable

Considerations:

• Verify that the cable has been tested and the test results are recorded. This information is required for the As-Built Document.

• Verify that only captive centerpin 75 Ohm Type-F connectors are used on the solid copper center conductor CATV 75 Ohm cable.

• Verify that the CATV cable is labeled with:

7.4.3.2 Installing RAUs in a Multiple Operator System

When installing both iDEN and Cellular systems in parallel, either as dual-band or multiple operator systems, you must take special provision to assure that the individual RAUs do not interfere with each other.

The 850/1900 MHz and 800/900/1900 MHz RAU’s antennas must be separated by at least 8 meters (26 feet) to assure that the iDEN downlink signals do not interfere with the Cellular uplink signals.

7.4.4 Configuring the System

Before the system can operate properly, use AdminBrowser to program the Fusion Main Hub with the frequency bands that are to be distributed. The Hub must be programmed with the same frequencies as the RAU used.

NOTE: The frequency bands should automatically be set on power up and this step should not be required.

Considerations:

• The AdminBrowser software, described in the AdminBrowser User Manual (PN D-620607-0-20), must be running on a PC/laptop.

• Crossover Ethernet cable with male connectors required.

Connecting the PC to the Fusion Main Hub to Run AdminBrowser

Connect the AC power cord to the Hub.

Make sure the Hub is grounded through the ground lug on the AC power and the frame ground lug as required. The warranty does not cover damage caused when an ungrounded Hub is powered on.

Plug the power cord into an AC power outlet.

Verify that all cables are properly connected on the Hub.

Turn on the power to the Hub.

All LEDs blink through the power up sequence. At each port where an RAU is detected (drawing current), the port LEDs lights green. The Fusion is orange during system boot and should turn green after about 90 seconds if it finds no faults. This state indicates the band’s are not programmed and provides feedback on the status of the RAU connections.

The LEDs blink for 20 seconds as a visual check that they are functioning.

• Use the pull-down to specify the Uplink and Downlink gain for each band. You can set system gain within the specified range in 1 dB increments.

• Use the pull-down to set the Uplink Automatic Level Control to either “Single” or “Multiple” for each band in the system. (The default is “Multiple.”

11.

In the Input/Output Alarms area, do the following for each Alarm Sense:

• Enable each Alarm Sense by using the check box.

• Use the pull-down to set the Normal State to Closed or Opened. (The default is “Closed.”

• Assign a label to each alarm sense.

12.

When you have completed inputting the desired information, click

Install System

to configure the system.

During configuration all disconnect statuses are cleared for attached RAUs; the frequency band, gain, and system label are set; logs are cleared; the system test is performed; and finally the system tree is refreshed. The icons should be:

Indicating that the band is correctly set.

Indicating that communications are OK.

If there are problems, the icons will be different and a message is displayed in the Messages pane.

13.

Connect the Main Hub to the RF source (for example, BTS or BDA).

Do not exceed the maximum input RF power (1 Watt) to the Fusion Main Hub. Exceeding the limit could cause permanent damage to the Hub.

CAUTION:Only carriers and their approved installers or LGC-authorized installers are allowed to connect to the RF source. Serious damage to the

equipment can occur if it is over-driven.

The Fusion system should now be operational. Using a mobile phone, walk your site and test the signal strength.

14.

Make sure to change the TCP/IP setting in your laptop back to their original values.

sponding legal sanctions of the national jurisdiction involved. Ownership of LGC Wireless equipment carries no automatic right of use.

7.5 Splicing Fiber Optic Cable

The fiber cable must have SC/APC connectors for the entire run. If it does not, you can splice a pigtail, which has SC/APC connectors, to the fiber cable.

LGC offers two pigtails: one for single-mode fiber (PN 4013SCAPC-3) and one for multi-mode fiber (PN 4012SCAPC-3).

LGC Wireless recommends fusion splices because they have the lowest splice loss and return loss. Mechanical splices have higher losses and higher back reflection than fusion splices and are not recommended.

Using a fusion splicer involves fusing together two butted and cleaved ends of fiber. The fusion splicer aligns the fibers and maintains alignment during the fusion process. Fusion splices have very low loss (typically less than 0.05 dB) and very low back reflection (return loss). Fusion splices should be organized in a splice tray designed to store and protect the splices.

Splicing Fiber Optic Cable

Fusion Splicing of Fiber and Pigtail

Before you begin, make sure the fusion splicer is set to the proper mode (that is, single- or multi-mode).

To fusion splice the fiber optic cable to the SC/APC pigtail: Option A

Secure both the fiber cable and the SC/APC pigtail in a splice tray that is installed immediately adjacent to the Hub.

Prepare the fiber end by cutting back the polyethylene jacket, the kevlar or fiberglass strength members, the extruded coating, and the buffer coating in order to expose the “bare fiber” – cladding plus core.

Ensure that sufficient slack is maintained in order to be able to reach the fusion splicer.

Clean the unclad fiber core using isopropyl alcohol and lint-free wipes.

Cleave the unclad fiber to the length prescribed by the fusion splicer’s specification sheets.

Repeat steps 2 through 4 for the SC/APC pigtail.

Pass the splice sleeve onto the fiber strand.

Position both fiber ends in the fusion splicer and complete splice in accordance with the fusion splicer’s operation instructions.

Place the sleeve and fused fiber into the fusion splicer’s heater.

11.

Allow time for the splice sleeve to cure.

12.

Return fiber splice to the splice tray, store the sleeve in a splice holder within the tray, and store excess cable length in accordance with the tray manufacture’s directions.

After successfully testing the fiber, plug the SC/APC pigtail into the proper optical port on the Hub.

To fusion splice the fiber optic cable to the SC/APC pigtail: Option B

Secure both the fiber cable and the SC/APC pigtail in a splice tray portion of a fiber distribution panel.

Ensure that sufficient slack is maintained in order to be able to reach the fusion splicer.

Clean the unclad fiber core using isopropyl alcohol and lint-free wipes.

Cleave the unclad fiber to the length prescribed by the fusion splicer’s specification sheets.

Repeat steps 2 through 4 for the SC/APC pigtail.

Pass the splice sleeve onto the fiber strand.

Position both fiber ends in the fusion splicer and complete splice in accordance with the fusion splicer’s operation instructions.

Ensure that the estimated loss for the splice as measured by the fusion splicer is

0.10 dB or better.

Slide the fusion splicing sleeve over the point of the fusion splice.

10.

Place the sleeve and fused fiber into the fusion splicer’s heater.

11.

Allow time for the splice sleeve to cure.

12.

Return fiber splice to the splice tray, store the sleeve in a splice holder within the tray, and store excess cable length in accordance with the tray manufacture’s directions.

13.

After successfully testing the fiber cable, plug the SC/APC pigtail into the back side of the SC/APC bulkhead in the Fiber Distribution Panel.

Install a SC/APC patch cord between the front side of the SC/APC bulkhead and the proper optical port on the Hub.

7.7 Connecting Contact Alarms to a Fusion System

The Fusion Main Hub can generate (source) two contact alarms as well as sense three external contact alarm.

• Alarm Source (refer to Section 7.7.1 on page 7-50)

The Fusion Main Hub has two alarm contacts, fault (major) and warning (minor). These contacts are normally-closed (NC) and will open when an internal alarm is detected.

NOTE: The contact can be changed to normally-open (NO) with AdminBrowser. This is not recommended since no alarm would be sent if power to the Fusion Main Hub fails.

• Fault is activated when any faults or disconnects are detected.

• Warning is activated when any warning conditions are detected except lockout or when the end-to-end system test is not valid.

• Alarm Sense (refer to Section 7.7.2 on page 7-53)

The Fusion Main Hub can monitor 3 external alarm contacts. Each port can be configured for normally-open (NO) or normally-closed (NC) contacts. The interface expects a set of floating contacts, and an external voltage source is not required for this interface. Use AdminBrowser to monitor the port status.

Table 7-8 lists the alarm types, equipment to which the Fusion Main Hub is connected, cable(s) used, and the faults and warnings that are detected.

Maintenance

9.2 Maintenance

Keep the fiber ports clean and free of dust. No other periodic maintenance of the Fusion equipment is required.

To clean the fiber ports:

You can clean the Hub’s fiber ports using canned compressed air or isopropyl alcohol and cotton swabs.

Considerations:

• If you use compressed air:

• The air must be free of dust, water, and oil.

• Hold the can level during use.

• If using isopropyl alcohol and foam-tipped swab:

• Use only 98% pure or more alcohol.

Procedure using compressed air:

Remove the connector’s dust cap.

Spray the compressed air away from the unit for a few seconds to clean out the nozzle and then blow dust particles out of each fiber port.

Procedure using isopropyl alcohol:

Remove the connector’s dust cap.

Dip a 2.5mm lint-free, foam-tipped swab in isopropyl alcohol and slowly insert the tip into the connector.

Gently twist the swab to clean the connector.

Insert a dry swab to dry the connector.

Additionally, you can use compressed air after the alcohol has completely evaporated.

9.3 Troubleshooting

NOTE: Fusion has no user-serviceable parts. Faulty or failed units are fully

replaceable through LGC Wireless.

Sources of potential problems include:

• Faulty cabling/connector

• Malfunction of one or more Fusion components

• Antenna, base station, or repeater problem

• External RF interface

• Tripped circuit breaker

• Equipment is not grounded

• Using an Ethernet crossover cable that does not support full hardware handshaking when using AdminBrowser

NOTE: Faulty cabling is the cause of a vast majority of problems. All CATV 75 Ohm cable should be tested to TIA-570-B specifications. The RAU will be damaged if the cable connector is not installed properly.

Troubleshooting

You must use AdminBrowser for troubleshooting the system, use the LEDs only as backup or for confirmation.

If you cannot determine the cause of a problem after following the recommended procedures, call LGC Wireless customer help hot line:

1-800-530-9960 (U.S. only) +1-408-952-2400 (International)

Or, email us at lgccustomersupport@lgcwireless.com.

Please provide the following information:

• Serial number of the unit

• Description of the problem

• Using AdminBrowser 1.00, access Special Features, then the Get Service Information window. Save and email this file to LGC Wireless.

• What is the length of the CATV cable? What type is it (for example RG-6)?

• Status of the LEDs on the unit

• Was the unit power cycled?

Use AdminBrowser’s “Clear All Disconnect Status” command if you are permanently removing the RAU from service. The Expansion Hub’s port LEDs should change to Off/Off.

Red Disconnect/reconnect the CATV

cable to force power-on reset to the RAU. If the port LEDs remain Red check for the exact cause of Expansion Hub faults using AdminBrowser.

Flashing Red (60 ppm)

The RAU reports a fault condition; check for the exact cause of Expansion Hub and RAU faults using AdminBrowser.

Flashing Red (60 ppm)

The Expansion Hub reports no connection, cable shorts, or a current port trap condition.

The RAU was previously connected, but it is not currently connected; the RAU cable is disconnected.

Lost communications with the RAU. The RAU could have powered down due to over current; cable could have been damaged.
