5 D OCUMENT OVERVIEW This guide instructs you in how to replace the following FlexWave modules in a Host Unit II, NEBS Level 3 Host Unit, or Host Expansion Unit (HEU) chassis: SeRF II Module System Module, which can be one of the following Host Units: Host System III Module or Host System II Module HEUS: Remote System II Module DC Power Supply Module DART Modules (Classic DARTs, Single- and Dual-SuperDARTs, Host-to-Host DARTs) Fan Module. This document provides module replacement information for the Host Unit II, NEBS Level 3 Host Unit, and the Host Expansion Unit. The term Host Unit refers to both of the Host Unit chassis types; should there be any differences in how the module replacement is handled between the two Host Units and/or an HEU, those differences will be clearly identified. There are two types of procedures in this book: Universal procedures are those procedures, such as logging in to a FlexWave EMS session, whose steps are the same regardless of the module being replaced. These steps are provided once in this guide, and then are referenced when appropriate to complete the procedure in each module replacement process. The replacement instructions vary according to unit and module type. Refer to the section that corresponds to the module type that is being replaced: "Replacing the SeRF II Module on page 8 "Replacing the Host or Remote System Module on page 22 "Replacing the DC Power Module on page 32 "Replacing a DART Module on page 36 "Replacing a Fan Module on page 39. There are several FlexWave Element Management System (EMS) Software Releases active at customer sites. This guide describes the FlexWave Software Release 9.0.x. If the Host Unit or HEU that you are working on is running an earlier FlexWave Software Release, refer to the corresponding FlexWave EMS user manual for comparable information.

7 Safely Working with FlexWave Hardware S AFELY WORKING WITH FLEXW AVE HARDWARE The following sections provide important information that you should read and know before working with any FlexWave hardware. Observe all cautions and warnings listed in this section. SAFETY PRECAUTIONS FOR THE HOST UNIT II, NEBS LEVEL 3 HOST UNIT, AND HEU Host Units and HEUs are restricted access equipment and only qualified service personnel should service and operate this equipment using appropriate tools. The NEBS Level 3 Host Unit is not suitable for installation as part of a Common Bonding Network (CBN) or an Isolated Bonding Network (IBN). The intra-building port(s) of the equipment or subassembly is suitable for connection to intra-building or unexposed wiring or cabling only. The intra-building port(s) of the equipment or subassembly MUST NOT be metallically connected to interfaces that connect to the OSP or its wiring. These interfaces are designed for use as intra-building interfaces only (Type 2 or Type 4 ports as described in GR-1089) and require isolation from the exposed OSP cabling. The addition of Primary Protectors is not sufficient protection in order to connect these interfaces metallically to OSP wiring. The maximum ambient operating temperature for the Host Unit is 50º C (122º F). Wet conditions increase the potential for receiving an electrical shock when installing or using electrically powered equipment. To prevent electrical shock, never install or use electrical equipment in a wet location or during a lightning storm. When loading the Host Unit or HEU in an equipment rack, make sure the mechanical loading of the rack is even to avoid a hazardous condition such as an unbalanced rack. The equipment rack in which the Host Unit or HEU is installed should safely support the combined weight of all the equipment it holds. SAFETY PRECAUTIONS FOR OPTICAL FIBER This equipment uses a Class 1 Laser according to FDA/CDRH rules. Laser radiation can seriously damage the retina of the eye. Do not look into the ends of any optical fiber. Do not look directly into the optical transceiver of any digital unit or exposure to laser radiation may result. Use an optical power meter to verify active fibers. To avoid the potential of dangerous amounts of radiation exposure, immediately place a protective cap or hood over any radiating transceiver or optical fiber connector. This practice also prevents dirt particles from entering the adapter or connector. You must clean the SFP optical ports at the Host Unit and at the Remote Unit, and clean the tip of the fiberpatch cords. Failure to clean the ports and cord tips may result in an optical RX or TX alarm state. Improper handling can damage fiber optic cables. Always allow sufficient fiber length to permit routing of patch cords and pigtails without severe bends. Do not bend fiber optic cable more sharply than the minimum recommended bend radius specified by the cable manufacturer. Do not apply more pulling force to the cable than specified. October 2017 CommScope, Inc. Page 3

8 Safely Working with FlexWave Hardware GUARD AGAINST DAMAGE FROM ELECTRO-STATIC DISCHARGE Electro-Static Discharge (ESD) can damage electronic components. To prevent ESD damage, always wear an ESD wrist strap when working on the Host Unit and when handling any of its components. Connect the ground wire on the ESD wrist strap to an earth ground source before touching the Host Unit or any of its components. Wear the wrist strap the entire time that you work with the Host Unit and its components. Place modules in anti-static packing material when transporting or storing them. COMPLIANCE 1 Notice: For installations, which have to comply with FCC RF exposure requirements, the antenna selection and installation must be completed in a way to ensure compliance with those FCC requirements. Depending on the RF frequency, rated output power, antenna gain, and the loss between the repeater and antenna, the minimum distance D to be maintained between the antenna location and human beings is calculated according to this formula: D [ cm] = where P [ mw ] 4 π PD[ mw / cm 2 ] P (mw) is the radiated power at the antenna, i.e. the max. rated repeater output power in addition to the antenna gain minus the loss between the repeater and the antenna. PD (mw/cm²) is the allowed Power Density limit acc. to 47 CFR (B) for general population / uncontrolled exposures which is f (MHz) / 1500 for frequencies from 300MHz to 1500MHz 1 for frequencies from 1500MHz to 100,000MHz RF exposure compliance may need to be addressed at the time of licensing, as required by the responsible FCC Bureau(s), including antenna co-location requirements of (b)(3). 2 Notice: For installations which have to comply with European EN50385 exposure compliance requirements, the following Power Density limits/guidelines (mw/cm²) according to ICNIRP are valid: 0.2 for frequencies from 10 MHz to 400 MHz F (MHz) / 2000 for frequencies from 400 MHz to 2 GHz 1 for frequencies from 2 GHz to 300 GHz 3 Notice: Installation of this equipment is in full responsibility of the installer, who has also the responsibility, that cables and couplers are calculated into the maximum gain of the antennas, so that this value, which is filed in the FCC Grant and can be requested from the FCC data base, is not exceeded.

SERF II MODULE REPLACEMENT PART 9: RESTORE THE SYSTEM CONFIGURATION A System Restore can only occur if a previous system configuration has been backed up as described in "SeRF II Module Replacement Part 1: Backup the Current System Configuration on page 8. A system restore requires a reboot of the Host Unit, as the system configuration is stored on the Host Unit. Rebooting the Host Unit therefore results in a loss of RF for the Host Unit and connected Remote Units until the Host Unit comes back up. Duration of lost RF is dependent on the number of Remote Units connected to the Host. Duration = 4 minutes x number of connected Remote Units. A system restore can only be performed by a user logged in as admin or by a user with Network Manager rights. A user assigned only Network User rights will not see the Restore option in the System Configuration menu. A System Restore can only occur if a previous system configuration has been backed up as described in "SeRF II Module Replacement Part 1: Backup the Current System Configuration on page 8. You typically perform a System Restore on a system that is running the same EMS software release that was active when the backup file was created. That is, if the system backup occurred on an system, and the system is now running 9.0, Restore will not function as expected. October 2017 CommScope, Inc. Page 17

22 Replacing the SeRF II Module There is one exception to this: a backup file made on a system immediately before an upgrade can be used to restore the system after the upgrade. For example, you can use an backup file to restore a system when it is running after an upgrade from to However, the backup file will not work if it was used to restore the system after it is upgraded beyond Refer to the current Release Notes for information on issues related to a backup/restore mismatch. The topics that relate to restoring a system backup have been divided into the following two topics: "System Restore Rules on page 18 "Perform a System Restore on page 19. System Restore Rules The System Restore page allows for a restoration of a backed up system configuration, as follows: The Restore function assumes that the same or comparable replacement hardware components are in place as when the Backup operation occurred. If hardware component changes have occurred, alarms that point to the differences will arise. The Restore function assumes that hardware components are in the same locations. That is, you can't move a DART from Slot 2 to Slot 4 between a system backup and restore. This is also true for fiber-optic connections: SFPs must be in the same locations between a system backup and restore. If a Host or Remote Unit or Host or Remote Unit components have been added (that is, was not part of the original system hardware setup), then the newly added Host or Remote Unit or the Host or Remote Unit component(s) will not be restored since it was not present during the system configuration backup. Care must be taken to ensure that a backup file is not restored onto a system where the hardware has been changed. For instance, do not swap an RF DART with a CDIU, then restore a backup file that was created on the original system in which RF DARTs were present and not the CDIUs. Spectrum systems only All of the DART configuration settings will be restored on the DRU, but the RAU and IFEU configuration settings are not affected. For example, the DRU Forward Gain, Forward Delay, Reverse Delay, and Remote Unit Name are restored. RAU Reverse Attenuation and Forward Attenuation, and the IFEU Name are unaffected by a restore; that is, if these settings were changed after a system backup, they do not revert to previous settings after a system restore. In a Multi-Host system, perform a System Restore on only one Host Unit at a time. Wait until the initial Host Unit returns with all Remote Units discovered and the System Busy message (System is busy Please wait.) has stopped being displayed before starting a System Restore on the next Host Unit. In a Multi-Host system, any Host Unit can perform a backup and restore on its system, which includes the Remote Units that are connected to it. General configurations are restored completely. RF configurations are restored for those RF Modules that belong to the Host Unit performing the restore. Since each Host Unit is free to do its own general configuration it is also free to restore the Remote Unit RF Module to previous settings. Since the admin can clear the configuration of all connected Remote DARTs (or the entire Remote Unit itself), this user can also restore the system back to any setting, such as taking a Remote Unit out of a Multi-Host setup and place it under the management of a single Host Unit. This can be achieved in the following two-step process: 1 Clear the Remote Unit configurations for the RF Modules not previously owned by this Host Unit. 2 Restore the Remote Unit configurations to a previous configuration when the Host Unit owned all the Remote Unit RF modules.

R EPLACING A FAN MODULE Continuous airflow to cool the Host Unit II and HEU chassis is provided by the Fan Module that is mounted on the left side of the chassis. The cooling fans blow cool air into the chassis, and heated air is exhausted through the vent openings on the right side of the chassis. The NEBS Level 3 Host Unit Chassis has fans that are mounted to the back of the chassis. The fans pull air through the air filters on the front of the chassis and exhaust the heated air out the back. This constant movement of air requires that the Fan Module be placed on a maintenance/replacement schedule: If a Host Unit or HEU is installed in a controlled environment, such as a base station or office environment, its Fan Module should meet the 40,000-hour fan life. If a Host Unit or HEU is installed in a dusty environment or an environment where there is a large range in ambient temperature (~0 C to 50 C), its Fan Module will require more maintenance and may not meet the forty-thousand-hour fan life. You should also check the Fan Module should either of these alarms occur: Fan Fault (fwuhstsyscardfanfault) Temperature High (fwuhstovertempfault). Regardless of the environment in which the Host Unit or HEU is installed, at the minimum, check the Fan Module on an annual basis. Verify the following: intake and exhaust vents are clear of obstructions and/or debris ambient temperature is less than 50C. It takes 8 steps divided into 2 sections to replace the Fan Module follow the steps in the order presented.

50 Universal Procedures The default FlexWave EMS page opens, which comprises the elements listed below. The System Tree will be populated with the devices that the EMS discovers, but no device will be selected. In the EMS Frame View, the default page displays what is shown when the Host Unit is selected in the System Tree. Host Unit Configuration View in the EMS Frame View HEUS IN THE EMS The following sections provide information on working with HEUs in the FlexWave EMS. Identifying an HEU in the System Tree In the System Tree, an HEU is identified as a DRU. Since a DRU is only found in a Spectrum system, within a FlexWave Prism system, a DRU icon can only indicate the presence of a Prism Host Expansion Unit (HEU). Page 46 October 2017 CommScope, Inc.

51 Universal Procedures Identifying an HEU in the EMS Pages In the EMS pages, such as the ones shown in Figure 4 and Figure 5 on page 47, an HEU can be identified as an HEU, an HEU Remote, or as a Remote. Figure 4. HEU Unit Identified in the Unit Information Page Figure 5. HEU Unit Identified in the Manage Alarms Page October 2017 CommScope, Inc. Page 47

52 Universal Procedures CHECK FOR ALARMS There are three methods to check for alarms on the Host Unit or on an HEU: "Access the EMS View Current Alarms Page on page 49 "View the Status of the Host Unit on page 51 "Temperature Table for Host Units on page 54. The EMS uses color codes and letters to indicate the level of the alarm or event in table cells, as described in Table 4. Table 4. Alarm Indications in the EMS GUI Alarm Type Color Code Letter (1) Comments No alarm Green A device is installed, and there is no active major or minor alarm. Informational Blue These are informational alarms that provide information on a successful user action, such as a change in a forward or reverse delay setting. Minor Yellow m A minor alarm is active. (2) Major Red M A major alarm is active. Disabled Gray D The alarm has been Disabled; see Enable and Disable Alarms in the FlexWave Software Release 9.0 System Setup and Provisioning Guide. No device Gray A device has not been installed. For example, Figure 6 shows the Module Status table in the Unit Information > View Status page, which shows that neither a DART nor a CDIU has not been installed in slots 3, 5, or 7. 1 If no letter is listed, the color code is the only alarm identifier. 2 If a major and a minor alarm are active for the same component, the major-alarm indicator is shown.

54 Universal Procedures Click on a row in the View Current Alarms table to open another web page as shown in Figure 7, which provides extended information on the alarm, including troubleshooting information. If necessary, follow the remedy provided. (For further information, see Extended Alarm Information in the FlexWave Software Release 9.0 System Setup and Provisioning Guide. Figure 7. Extended Alarm Information via the Get Information > Current Alarms Table Identifying Alarms that Correspond to an HEU With the exceptions noted below, generic alarms that correspond to Remote Units also apply to the HEU. The Temperature High alarm for Remote Units is generated when the ambient temperature for an HEU SeRF Module goes over 50 C. The DRU Temperature Low alarm is generated when the ambient temperature for an HEU SeRF Module goes below -5 C. HEUs do not support the Uplink Inactivity Fault. HEUs do not have LPAs, LNAs and PDs. Consequently, there will be no Remote Unit alarms related to Linear Power Amplifier (LPA), LNA and PD modules for HEUs. For further information on alarms, refer to the FlexWave Prism and Spectrum Element Management System Alarm Reference. Page 50 October 2017 CommScope, Inc.

56 Universal Procedures Module Status Table for Host Units The Module Status table shows which slots are occupied and whether a slot contains a DART or a CDIU. For DARTs, columns 1 through 8 correspond to the slot in which the DART resides (Column 1 = Slot 1, and so forth). CDIUs, however, will have two columns with the same slot name, one for Path A and one for Path B. In the graphic below, the CDIU is installed in slot 1, so it is represented in the GUI as being installed in Slot 1 with a column for Path A and another column for Path B. If a column has no background color, that slot is unoccupied. The DART alarms shown in the Module Status table are also applicable to CDIUs. The Module Status table has the following elements: DART Fault Summary of DART Downconverter 1 Synthesizer Unlocked, Downconverter 2 Synthesizer Unlocked, Upconverter Synthesizer Unlocked, DC Supply Fault alarms, and DART FPGA status. DART Over Drive Red indicates that the RF signal received from the BTS/BDA is too strong. Fault threshold is +19 dbm. DART Under Drive DART forward RF input signal is below its normal operating limit. The DART Under Drive threshold is equal to [Fully Loaded Max Composite Input Power 21 dbm], based on the Fully Loaded Max Composite power setting (System Configuration > Provision System > Forward RF > Forward Link Budget (RF Slots)). Host Module Missing Fault Host Unit is missing a DART Module or CDIU. DART Hardware Mismatch Host DART does not support the selected passband. Fault occurs when a Host DART is replaced with another DART of the incorrect type. Page 52 October 2017 CommScope, Inc.

57 Universal Procedures Optical Status Table for Host Units The Optical Status table (shown below) shows the current usage and alarm status of the optical ports on the Host Unit plus the current values of some key operating parameters. The Host Unit has eight optical ports, but the Optical Status table only shows physically present SFPs. Each port in the table (where SFP 1 is column 1, SFP 2 is column 2, and so forth) represents one set of FWD and REV paths between a Host Unit and Remote Unit. The Optical Status table has the following elements: Optical RX High BER high bit error rate (BER) detected by fiber optic receiver. Fault threshold is Threshold cannot be changed. Optical RX No Light no signal detected by optical receiver. Optical Transmitter Fault SFP optical transmitter failed. Optical Over Drive SFP optical receive input power above specification. The fault threshold cannot be changed, and is 1dBm for IR -9dBm for LR. Optical Under Drive SFP optical receive input power below specification. The fault threshold cannot be changed, and is -18dBm for IR -27dBm for LR. Module Missing Fault one of the Host Unit SFPs is missing. Note that the Module Missing Fault only activates if there is an active link on that SFP. (If you pull an SFP from the Host Unit that has not been linked, the EMS does not activate a Module Missing Fault, it just removes the SFP from its database. October 2017 CommScope, Inc. Page 53

58 Universal Procedures Host Status Table The Host Status table (shown at the right) shows the current overall status of the Host Unit. Host Major Contact Alarm Output Active Major Contact Alarm Output active. Host Minor Contact Alarm Output Active Minor Contact Alarm Output active. Remote Major Contact Alarm Output Active major alarm is present on any Remote Unit connected to the Host Unit. Red indicates Normally Open/Normally Closed (NO/NC) major alarm contacts are in an alarm position. These connections are typically wired to a local alarm alert system. Remote Minor Contact Alarm Output Active minor alarm is present on any Remote Unit connected to the Host Unit. Yellow indicates that Normally Open/ Normally Closed (NO/NC) minor alarm contacts are in an alarm position. These connections are typically wired to a local alarm alert system. SeRF Fault state of the SeRF. Red indicates that either the SeRF clock source is unacceptable or the SeRF card FPGA is not programmed. Fan Fault state of the Host Unit chassis fan. Red indicates that the Host Unit chassis fan is spinning too slowly. Temperature High red indicates that the current temperature of the Host Unit interior is above its operating limits. Fault threshold is 62 C. Host Temperature Low yellow indicates that the current temperature of the Host Unit interior is below its operating limits. Fault threshold is 0 C. Clock Priority Level Conflict more than one Host Unit in a Multi-Host setup has the same Clock Priority Level, all Host Units in conflict raise the Master Clock Priority Level Conflict alarm. However, the Clock Priority Level Conflict alarm is a transient alarm; it will be cleared within 30 seconds, as the EMS automatically changes the Clock Priority Level on one or both of the Host Units so that the two Host Units have different clock priority values. If it is intended that a specific Host Unit should provide the master clock, the new priority values should be checked and adjusted manually if necessary (see "Set the System Reference Clock and Clock Priority on page 54). Clock Configuration Invalid the system is currently configured to use the internal 10 MHz clock reference, but the CDIU requires an external reference, resulting in no RF for the CDIU bands. Temperature Table for Host Units The Temperature table gives the current temperature of the Host Unit chassis interior (as detected by the Host Unit) in degrees Centigrade and Fahrenheit.
