ADCP-75-159 • Issue 1 • August 2003 • Section 3: Host Unit InstallationPage 3-4© 2003, ADC Telecommunications, Inc.3 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. 3. Reinstall both mounting brackets so the long side of the bracket is flush with the HU frontpanel as shown in Figure 3-2. Use the screws removed in step 2 to re-attach the brackets tothe HU chassis. Figure 3-2. Installing the Mounting Brackets for 23-Inch Rack InstallationsWarning: 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. 17864-AFOR INSTALLATION IN 23-INCHRACKS, REMOVE AND REINSTALLMOUNTING BRACKETS AS SHOWN

Locate the chassis ground stud at the rear of the HU as shown in Figure 3-4. 4. Attach the ring end of the wire to the chassis ground stud (see Figure 3-4). 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. Note: Provide a minimum of 3 inches (76 mm) of clearance space on both the left andright sides of the HU for air intake and exhaust. Note: Be sure to maintain reliable grounding. Pay particular attention to ground sourceconnections.17865-A
ADCP-75-159 • Issue 1 • August 2003 • Section 3: Host Unit InstallationPage 3-6© 2003, ADC Telecommunications, Inc.Figure 3-4. Chassis Ground Stud5 COAXIAL CABLE CONNECTIONSThe RF interface between the HU and the EBTS is supported through two N-type femaleconnectors mounted on the HU rear panel. One connector provides the coaxial cable connectionfor the forward path (downlink) signal and the other connector provides the coaxial cableconnection 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 EBTS. A signal level that is greater than –20 dBm will overdrive andpossibly damage the HU receiver. Refer to Section 4, Subsection 2.3, before completing theforward path connection at the EBTS. If the Primary Interface Panel and Expansion Panel arerequired, refer to the Digivance Long Range Coverage Solution SMR Interface Panels UserManual (ADCP-75-143) for the installation procedures. The HU should be mounted as close aspossible to the EBTS to minimize cable losses. Use the following procedure to route andconnect the forward and reverse path coaxial 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 EBTS 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 3-5.5. Connect the reverse path cable to the REVERSE RF OUT connector on the HU frontpanel (see Figure 3-5). Note: Do not connect the forward path cable at the EBTS until the composite forward pathRF signal level is measured and the amount of attenuation required is determined. 17866-A

WDM Installation7 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 rear 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. 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. 18827-AREMOVE COVER PLATEFOR WDM MODULEINSTALLATIONWDM MODULE

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 3-7.Figure 3-7. Fiber Optic Cable Connections To Host Unit6. Route the patch cords from the HU to the fiber distribution panel. 7. 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. Note: To protect the optical receivers, insert a 10 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. 18828-ASC OPTICALCONNECTORPORT 1FORWARD PATHPORT 2REVERSE PATH
