Use the followingprocedure to unpack and inspect the HU and any accessories:1. Open the shipping cartons and carefully unpack each component from the protectivepacking material.2. Check each component for broken or missing parts. If there are damages, contact ADC(see section 6at the end of this manual) for an RMA (Return Material Authorization) andto reorder if replacement is required.2 OSP FIBER CABLE INSTALLATION GUIDELINESThe outside plant (OSP) fiber optic cables should be routed between the HU and RU andterminated before the equipment is installed. Adiagram of atypical OSP cable routing is shownin Figure 3-1.At the HU, the OSP cable should be terminated at afiber distribution panel andspliced to pigtails. Jumper patch cords may then be used to link the HU optical ports to the OSPcable terminations. Whenever possible, aguideway such as the FiberGuide system should beprovided to protect the fiber optic patch cords from damage and to prevent excessive bending.The procedures for connecting the OSP cable optical fibers to the HU is provided in Section 7.
ADCP-75-134 • Issue A • April 2002 • Section 3: Host Unit InstallationPage 3-3©2002, ADC Telecommunications, Inc.Figure 3-1. Typical OSP Cable RoutingAt the RU, the OSP fiber optic cable should be spliced to aconnectorized outdoor-rated cable(consisting of individual jacketed pigtails) which is routed into the RU cabinet. The individualpigtails can then be connected directly to the STM optical ports. Aconnector is provided on thebottom of the RU cabinet to seal the cable entry point and provide strain relief. The procedurefor routing the fiber cable into the RU cabinet and for connecting the pigtail leads to the STM isprovided in the Digivance LRCS Single Band SMR Remote Unit Installation Instructions(ADCP-75-135).When all splices and terminations are completed, test each fiber for optical loss as described inSection 5 of this document. The optical loss budget for 9/125, single-mode, dark fiber is 17 dB(typical). The power level of the received optical signal should not exceed –7 dBm to avoidoverdriving the optical receiver. If necessary, use an in-line optical attenuator to adjust the signallevel.HOST UNITFIBER DISTRIBUTION PANELXXSTMREMOTE SITEHOST SITEPATCHCORDSPLICEPIGTAILSPLICEENCLOSUREINDOOR/OUTDOORCABLE WITH PIGTAIL LEADSOUTSIDE PLANTCABLEREMOTE UNITCABINET16889-A

If the application does not require the use of aWDM, skip this section and proceed to Section 4.The version of the WDM that is used with the HU consists of one or two WDM modules and aWDM mounting shelf. Each WDM module can support two HU’s and each WDM mountingshelf can hold two WDM modules. Afully loaded WDM mounting shelf can therefore supportfour HU’s.When multiple HU’s require connection to aWDM, the WDM mounting shelf and the HU’sshould be mounted in the equipment rack as shown in Figure 3-2.This configuration allows thepigtail leads from the two WDM modules to be connected directly to the optical ports on anyone of the four HU’s.Figure 3-2. Typical WDM and HU ConfigurationThe WDM mounting shelf may be mounted in either a19-inch or 23-inch EIA or WECOequipment rack. Four #12-24 screws are provided for securing the mounting shelf to the rack.Use the following procedure to install the WDM mounting shelf in the equipment rack and tomount the WDM modules in the WDM mounting shelf:1. The WDM mounting shelf is shipped with the mounting brackets installed for 19-inch EIArack installations. If installing the mounting shelf in a19-inch EIA rack, proceed to step 5.If installing the mounting shelf in a19-inch WECO rack, a23-inch EIA rack, or a23-inchWECO rack, proceed to step 2.WDM MOUNTINGSHELF(WITHOUT MODULES)16886-APOWERWORXFUSE PANELHOST UNITS

WDM Mounting Shelf and WDM Module Installation4 HU MOUNTING PROCEDUREThe HU may be mounted in either a19-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 arack, make sure the mechanical loading of the rack is even to avoid ahazardouscondition such as aseverely 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 amulti-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 a19-inch rack, proceed to step 4. If mounting the HU in a23-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 awet location or during alightning 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 alength of #18 AWG (1.00 mm) insulated stranded copper wire for use as achassisgrounding wire.2. Terminate one end of the wire with aring 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 EBTS is supported through either two (non-diversity)or three (diversity) type Nfemale connectors mounted on the HU front panel. On non-diversityunits, one connector provides the coaxial cable connection for the forward path (downlink)signal and the other connector provides the coaxial cable connection for the reverse path(uplink) signal. On diversity units, athird connector provides the coaxial cable connection forthe diversity reverse path (uplink) signal.Note: Be sure to maintain reliable grounding. Pay particular attention to ground sourceconnections.16169-A
ADCP-75-134 • Issue A • April 2002 • Section 3: Host Unit InstallationPage 3-9©2002, ADC Telecommunications, Inc.In SMR installations, it is usually necessary to install an external attenuator in the forward pathlink between the HU and the EBTS. The procedure for determining the value of the externalattenuator is provided in SECTION 4: OPERATION. The HU should be mounted as close aspossible to the EBTS to minimize cable losses. Use the following procedure to route theforward and reverse path coaxial cables and connect them 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 and the diversity reverse path cable (ifthe HU supports diversity) between the HU and the EBTS interface (per system designplan) and cut to the required length. Allow sufficient slack for dressing and organizingcables at the HU and for installing an external attenuator in the forward path link.3. Terminate each cable with atype Nmale 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. If the HU supports diversity, connect the diversity reverse path cable to the REVERSE 2RF OUT connector on the HU front panel (see Figure 3-8).7. Dress and secure cables at the HU.8. Complete all remaining coaxial connections at the EBTS interface as specified in thesystem design plan.16887-ATYPE-N MALECONNECTORFORWARD RF INCONNECTOR(FORWARD PATH)REVERSERF OUT CONNECTOR(REVERSE PATH)REVERSE 2RF OUT CONNECTOR(DIVERSITY REVERSE PATH)
ADCP-75-134 • Issue A • April 2002 • Section 3: Host Unit InstallationPage 3-10©2002, ADC Telecommunications, Inc.7 OPTICAL CONNECTIONSThe optical interface between the HU and the RU is supported by either two (non-diversity) orthree (diversity) optical ports. Each optical port consists of an SC optical adapter which ismounted on the HU front panel. Port 1provides the optical fiber connection for the forward path(downlink) signal. Port 2provides the optical fiber connection for the reverse path (uplink)signal. Port 3provides the optical fiber connection for the diversity reverse path (uplink) signal.The optical connections are dependent on whether or not aWDM (optional accessory) isinstalled. If the installation does not include aWDM, proceed to Section 6.1 for the opticalconnections procedure. If the installation does include aWDM, proceed to Section 6.2 for theoptical connections procedure.7.1 Optical Connections Without WDMUse the following procedure to connect the optical fibers when aWDM is not installed with theHU:1. Obtain two (non-diversity) or three (diversity) patch cords that are of sufficient length toreach from the HU to the fiber distribution 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 the connector. For diversitysystems, designate and label or tag athird patch cord as the diversity reverse path link.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 connector supplier’s recommendations) and theninsert the connector into the appropriate optical port as shown in Figure 3-9 and asspecified by the following:Port 1 - Forward path patch cordPort 2 - Reverse path patch cordPort 3 - Diversity reverse path patch cord5. Route the patch cords from the HU to the fiber distribution panel.Danger: This equipment uses aClass 1Laser 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. Aprotective 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: 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.
