If the application does not require the use of a WDM system,skip this section and proceed to Section 4. At the HU, the WDM system consists of a WDM host module and a WDM host modulemounting shelf. Each host module can support two HU’s and each host module mounting shelfcan hold two host modules. A fully loaded host module mounting shelf can therefore supportfour HU’s. When multiple HU’s require connection to a WDM system, the host module mounting shelf andthe HU’s should be mounted in the equipment rack as shown in Figure 3-2. This configurationallows the pigtail leads from the two host modules to be connected directly to the optical portson any one of the four HU’s. Figure 3-2. Typical WDM and HU ConfigurationThe WDM host module mounting shelf may be mounted in either a 19-inch or 23-inch EIA orWECO equipment rack. Four #12-24 screws are provided for securing the mounting shelf to therack. Use the following procedure to install the host module mounting shelf in the equipmentrack and to mount the host modules in the host module mounting shelf: 1. The host module mounting shelf is shipped with the mounting brackets installed for 19-inch EIA rack installations. If installing the mounting shelf in a 19-inch EIA rack, proceedto step 5.

WDM Host Module Mounting Shelf and WDM Host Module Installation4 HU MOUNTING PROCEDUREThe HU may be mounted in either a 19-inch or 23-inch EIA or WECO equipment rack. BothUS standard and metric machine screws are included for rack mounting the HU. When loadingthe HU in a rack, make sure the mechanical loading of the rack is even to avoid a hazardouscondition such as a severely unbalanced rack. The rack should safety support the combinedweight of all the equipment it holds. In addition, maximum recommended ambient temperaturefor the HU is 50º C (122º F). Allow sufficient air circulation or space between units when theHU is installed in a multi-rack assembly because the operating ambient temperature of the rackenvironment might be greater than room ambient. Use the following procedure to install the HU in the equipment rack:1. The HU is shipped with the mounting brackets installed for 19-inch rack installations. Ifmounting the HU in a 19-inch rack, proceed to step 4. If mounting the HU in a 23-inchrack, proceed to step 2. 2. Remove both mounting brackets from the HU (requires TORX screwdriver with T20 bit)and save screws for reuse. Warning: Wet conditions increase the potential for receiving an electrical shock wheninstalling or using electrically powered equipment. To prevent electrical shock, never install oruse electrical equipment in a wet location or during a lightning storm. Note: To insure that all optical connectors remain dust-free during installation, leave all dustcaps and dust protectors in place until directed to remove them for connection. 16888-A WDM MODULEWDM MOUNTINGSHELF

Obtain a length of #18 AWG (1.00 mm) insulated stranded copper wire for use as achassis grounding wire. 2. Terminate one end of the wire with a ring terminal. 3. Locate the chassis ground stud at the rear of the HU as shown in Figure 3-7. Figure 3-7. Chassis Ground Stud4. Attach the ring end of the wire to the chassis ground stud (see Figure 3-7). 5. Route the free end of the chassis grounding wire to an approved (per local code orpractice) earth ground source. 6. Cut the chassis grounding wire to length and connect it to the approved ground source asrequired by local code or practice. 6 COAXIAL CABLE CONNECTIONSThe RF interface between the HU and the BTS is supported through two N-type femaleconnectors mounted on the HU front panel. One connector provides the coaxial cableconnection for the forward path (downlink) signal and the other connector provides the coaxialcable connection for the reverse path (uplink) signal. In most installations, it is usually necessary to insert some attenuation in the forward path linkbetween the HU and the BTS. A signal level that is greater than –9 dBm will overdrive andNote: Be sure to maintain reliable grounding. Pay particular attention to ground sourceconnections.16169-A
ADCP-75-158 • Issue 1 • July 2003 • Section 3: Host Unit InstallationPage 3-9© 2003, ADC Telecommunications, Inc.possibly damage the HU receiver. Refer to Section 4, Subsection 2.3, before completing theforward path connection at the BTS. If the Conditioning Panel or Duplexing Panel is required,refer to the Digivance 800 and 1900 MHz Interface Panels User Manual (ADCP-75-147) for theinstallation procedures. The HU should be mounted as close as possible to the BTS to minimizecable losses. Use the following procedure to route and connect the forward and reverse pathcoaxial cables to the HU: 1. Obtain the required lengths of high performance, flexible, low loss 50-ohm coaxialcommunications cable (RG-400 or equivalent) for all coaxial connections. 2. Route the forward and reverse path coaxial cables between the HU and the BTS interface(per system design plan) and cut to the required length. Allow sufficient slack for dressingand organizing cables at the HU and for installing an external attenuator in the forwardpath link. 3. Terminate each cable with an N-type male connector following the connector supplier’srecommendations. 4. Connect the forward path cable to the FORWARD RF IN connector on the HU frontpanel as shown in Figure 3-8.Figure 3-8. Forward and Reverse Path Coaxial Cable Connections5. Connect the reverse path cable to the REVERSE RF OUT connector on the HU frontpanel (see Figure 3-8). 6. Dress and secure cables at the HU. 7. Complete all remaining coaxial connections as specified in the system design plan. Note: Do not connect the forward path cable at the BTS until the composite forward pathRF signal level is measured and the amount of attenuation required is determined. 18655-ATYPE-N MALECONNECTORFORWARD RF INCONNECTOR(FORWARD PATH)REVERSERF OUT CONNECTOR(REVERSE PATH)
ADCP-75-158 • Issue 1 • July 2003 • Section 3: Host Unit InstallationPage 3-10© 2003, ADC Telecommunications, Inc.7 OPTICAL CONNECTIONSThe optical interface between the HU and the RU is supported by two optical ports. Each opticalport consists of an SC optical adapter which is mounted on the HU front panel. Port 1 providesthe optical fiber connection for the forward path (downlink) signal. Port 2 provides the opticalfiber connection for the reverse path (uplink) signal. The optical connections are dependent on whether or not a WDM host module (accessory) orCWDM host module (accessory) is installed. If the installation does not include either a WDM orCWDM module, proceed to Section 7.1 for the optical connections procedure. If the installationincludes a WDM module, proceed to Section 7.2 for the optical connections procedure. If theinstallation includes a CWDM module, refer to the Digivance System Coarse WavelengthDivision Multiplexer User Manual (ADCP-75-142) for the optical connection procedure. 7.1 Optical Connections Without WDM or CWDM systemUse the following procedure to connect the optical fibers when a WDM or CWDM host module isnot installed with the HU: 1. Obtain two patch cords that are of sufficient length to reach from the HU to the fiberdistribution panel. 2. Designate one of the patch cords as the forward path link and the other as the reversepath link and attach an identification label or tag next to each connector.3. Remove the dust caps from the HU optical ports and from the patch cord connectors thatwill be connected to the HU. 4. Clean each patch cord connector (follow patch cord supplier’s recommendations). 5. Insert the connector into the appropriate optical port as shown in Figure 3-9.6. Route the patch cords from the HU to the fiber distribution panel. Danger: This equipment uses a Class 1 Laser according to FDA/CDRH rules. Laser radiationcan seriously damage the retina of the eye. Do not look into the ends of any optical fiber. Do notlook directly into the optical transmitter of any unit or exposure to laser radiation may result.An optical power meter should be used to verify active fibers. A protective cap or hood MUSTbe immediately placed over any radiating transmitter or optical fiber connector to avoid thepotential of dangerous amounts of radiation exposure. This practice also prevents dirt particlesfrom entering the connector. Note: To protect the optical receivers, insert a 15 dB attenuator in each optical path. Afterthe optical power has been measured, the attenuator may be resized or removed.Note: The HU optical adapters are angled to the left. Therefore, patch cords should alwaysbe routed to the HU from the left side of the rack. Routing patch cords to the HU from theright side of the rack may exceed the bend radius limitations for the optical fiber.

At the fiber distribution panel, identify the OSP optical fiber terminations that correspondto the forward and reverse path. 8. Remove the dust caps from the from the patch cord connectors. 9. Clean each patch cord connector (follow patch cord supplier’s recommendations) and thenmate the connector with the appropriate OSP optical fiber termination. 10. Store any excess patch cord slack at the fiber distribution panel. 7.2 Optical Connections With WDM SystemUse the following procedure to connect the optical fibers when a WDM module is installed withthe HU: 1. Obtain a patch cord that is of sufficient length to reach from the WDM host module to thefiber distribution panel. 2. Remove the dust cap from Port 1 or Port 4 on the WDM module and from the patch cordconnector that will be connected to the WDM module. Note: Each WDM module can support two separate HU’s.

This process assumes that the various units have beeninstalled in accordance with the system design plan. 1.1 Tools and MaterialsThe following tools and materials are required in order to complete the procedures in thissection: • Portable spectrum analyzer or RF power meter• AC/DC voltmeter• External attenuators (if specified in system design plan)• PC-type computer with Digivance Element Management System (EMS) Version 2.0software installed• Straight-through RS-232 DB-9 interface cable (ADC part # 1192835)• Handset• Pencil or pen• Writing padContent Page
ADCP-75-158 • Issue 1 • July 2003 • Section 4: OperationPage 4-2© 2003, ADC Telecommunications, Inc.1.2 Readiness CheckBefore starting the turn-up process, inspect the complete Digivance system to verify that allcomponents of the system are ready to be powered-up. This will ensure that no units of thesystem will be damaged during turn-up and that all existing systems will continue to functionproperly. 1.2.1 Host Unit Installation ChecksComplete the following checks at the HU prior to starting the turn-up process: 1. Verify that the ON/OFF switch on the HU is in the OFF position (press O). 2. At the fuse panel, install a 3 Amp GMT fuse in the circuit that supplies DC power to the HU. 3. Using a DC voltmeter, verify that the DC voltage level at the HU power terminals isbetween ± 21 to ± 60 VDC power (nominal ± 24 or ± 48 VDC). The DC power provided tothe HU can be either polarity.4. Verify that all electrical and optical connections have been completed and that all opticalfibers, coaxial cables, and wires are properly routed and secured. 1.2.2 Remote Unit Installation ChecksComplete the following checks at the RU prior to starting the turn-up process: 1. Verify that the ON/OFF switch on the STM is in the OFF position (press O). 2. Verify that the MUTE/NORM/RESET switch on the LPA in the MUTE position. 3. At the AC breaker box, close the circuit breaker for the circuit that supplies AC power tothe RU. 4. Using an AC voltmeter, verify that the AC voltage level at the AC outlet is between 110and 120 VAC (for 120 VAC powered systems) or between 220 and 240 VAC (for 240 VACpowered systems). 5. Verify that all electrical and optical connections have been completed and that all opticalfibers, coaxial cables, and wires are properly routed and secured. 2 TURN-UP SYSTEM AND VERIFY OPERATIONThe process of turning-up the system and verifying operation involves powering up the varioussystem components, verifying that the LED indicators show normal operation, setting the sitenumber and name, adjusting the RF signal levels, and adjusting the path delay.
ADCP-75-158 • Issue 1 • July 2003 • Section 4: OperationPage 4-3© 2003, ADC Telecommunications, Inc.2.1 Turn-Up ProcedureEach Digivance system should be turned-up separately before being networked together withmultiple systems through the CAN interface. Use the following procedure to turn-up eachDigivance system: 1. Temporarily disconnect the external alarm system or notify the alarm system provider thattesting is in progress. 2. If the HU is networked together with multiple HU’s, temporarily disconnect the CAN cablesfrom the NET IN and NET OUT ports of each HU. 3. Determine if the forward path composite input signal level at the Host Unit FORWARD RF INport is appropriate for the required RF output signal level and adjust by installing an externalattenuator if necessary. Refer to Section 2.3 for the calculation and adjustment procedure. 4. Connect the EMS computer (if not already connected) to the SERVICE connector on theHU or STM front panel. If necessary, a separate laptop computer loaded with the EMSVersion 2.0 software can be temporarily connected and used to initially configure thesystem. 5. Place the ON/OFF switch on the HU in the ON position (press I). 6. Make sure the switch on the LPA is in the MUTE position and then place the ON/OFFswitch on the STM in the ON position (press I). 7. Wait 6 to 8 seconds for the HU and the RU modules to initialize and then observe the LEDindicators on the HU, STM and LPA. Refer to Section 5 for the troubleshootingprocedures if the indicators do not respond as specified. 8. Start up the EMS Version 2.0 software program. The EMS main window will open asshown in Figure 4-1. Note: The EMS software should be installed on a PC-type computerand the PC’s COM port should be configured to interface with the HU. For informationabout installing the EMS software and configuring the PC’s COM port, refer to theDigivance Element Management System Software User Manual (ADCP-75-125). Note: By default, all HU’s and RU’s are programmed with the same site number andname. This can cause problems for the EMS if multiple HU’s with the same site numberand site name are networked together through the CAN interface. It is therefore necessaryto temporarily disconnect the CAN interface cables from the HU when configuring thesystem for operation until a unique site number and name can be assigned.
