Chapter 1Product Description

IntroductionThis manual provides information and procedures for installation, operation, and maintenance of the OS-1991Multi-Carrier Power Amplifier (MCPA) Outdoor Booster System.

Scope of ManualThis manual is intended for use by service technicians familiar with similar types of equipment. It containsservice information required for the equipment described and is current as of the printing date. Changes whichoccur after the printing date may be incorporated by a complete manual revision or alternatively as additions.The manual is organized into the following chapters:

General DescriptionThe outdoor system (OS), shown in Figures 1-1 through 1-4, is a three-way combined, single-sector system.The system operates in a maximum of 65 MHz transmit frequency band (1930 to 1995 MHz) and a maximuminstantaneous bandwidth of 65 MHz. The system uses an uplink frequency range of 1850 to 1915 MHz.

The OS has a sturdy aluminum IP55 rated cabinet with front and rear locking hinged doors equipped withintrusion alarms. The door latches are 1/4 turn and require a 10 mm hex socket wrench or nut driver to openand close. The doors can be secured with a padlock with a 1/2 inch maximum shank diameter. The front andrear doors both contain a removable, washable air filter.

Bolt inserts located on the cabinet side, top, and bottom panels are for mounting the OS to a secure fixedlocation. RF connections are located on the interface bulkhead plate at the bottom rear of the cabinet. Externalpower and alarm cables are routed through access holes located adjacent to the bulkhead. Cabinet ground isalso located next to the interface bulkhead.

The OS system provides three forms of alarm reporting; Form-C contact closure, ethernet (web page), andwireless modem. Intrusion is reported via Form-C only.

Major features of the OS cabinet include the following:

MCPAThe MCPA module, shown in Figure 1-5, is a 1900 MHz RF amplifier. The MCPAs operational features includea front panel RF OFF/ON/RESET switch and a multicolored LED indicator to display system status. The MCPARF outputs are combined by an external 3:1 combiner. MCPA faults are reported via the UCM.

OS-1991 General Description

RF Conditioning Unit (RFCU)The RF Conditioning Unit (RFCU) combines up to six separate BTS feeds; two duplexed and four simplexed.The RFCU combines, attenuates, and conditions the RF signals. If a critical system failure occurs, the RFCUplaces the system into bypass mode.

Universal Control Module (UCM)The Universal Control Module (UCM), shown in Figure 1-7, provides control and monitoring of the OSoperation. Front panel membrane key switches provide the capability to navigate through a menu-drivendisplay program. Refer to Chapter 3 for a complete description of the UCMs features.

ModemThe wireless modem, shown in Figure 1-8, receives fault data from the UCM after it has been converted fromRS485 serial data into Point to Point Protocol (PPP) data packets to support a type 2 SNMP (System NetworkManagement Protocol) format. The modem transmits the SNMP data (inform messages) to a remote locationwhere it is read by the SNMP manager application.

In a multi-sector site, only one OS cabinet (sector one) requires a modem. The OS cabinets for the othersectors are connected to the sector one OS cabinet by a RS485 interface. Refer to Figure 1-9 for a blockdiagram of the OS to remote location communication. When multiple OS boosters are daisy-chained together,each booster must be programmed via the UCM to a unique address. Up to a total of four boosters can besupported by one modem. The modem module also includes an Etnernet interface. Use this interface to viewstatus and configure the MODEM and system parameters from a web page.

Power SystemThe power system shown in Figure 1-10, contains up to four +27 VDC plug-in 1300 watt rectifier modules.Therectifier modules converts the system AC input power to supply +27 VDC to each MCPA and the UCM.Performance of the power system is monitored and reported via the UCM. Power system faults are mapped toForm-C and wireless modem alarms.

The two Rx channels provide DC power via Bias-Ts to external TMA modules. Each channel is programmablevia the UCM. The UCM monitors and reports DC current. Loss of current or excessive current generates a faultand disables the channel. All fault modes are continuously monitored for fault auto recovery. TMA power isprovided independent of the bypass status.

FansThe system is cooled by two variable speed DC fans that provide air flow through the booster cabinet. One fanis located on the front door and one on the rear door. The fans draw filtered ambient air through the front panelvents and sends heated air out the rear of the cabinet.

The variable speed fans are dependant on the MCPA, rectifier, UCM temperature sensors, and door intrusionstatus. Fan operation is disabled for the fans of any open door. Pulling out the door intrusion switch plungeremulates a door closure and activates the fan operation.

The variable speed fans maintain adequate cooling by operating at the slowest possible speed. Alltemperature sensors are monitored by the UCM and the hottest device controls the fan speed. Fan speedincrements or decrements by one step per one minute minimum.

Form-C AlarmsThe Form-C method includes four alarm levels detailing alarm severity as follows:

Form-C alarm reporting is disabled while the modem I/O is active.

❑ Minor - System requires maintenance.❑ Major - System operating but not at optimum performance.❑ Critical - System disabled and bypass active due to a loss of Tx or Rx.❑ Intrusion - Status of the front and rear door closure. System operation not affected.

General Description OS-1991

External AlarmsThe OS booster is capable of monitoring and reporting external Form-C alarms as listed in Table 1-1. Fourchannels are provided and each channel is programmed via the UCM for NO or NC faults. The four channelsare mapped to Form-C alarm outputs and the wireless modem for specific applications. The mapping is hardcoded.

(1) Could be critical and bypass if all MCPAs exhibit a fault. If critical, a BYPASS MODEM command is also required.

(2) Could be critical and bypass if both external alarm 1 and external alarm 3 exhibit faults. If critical, a BYPASS MODEM command is also required. (3) Could be critical and bypass if both Rx channels are faulted. If critical, a BYPASS MODEM command is also required.

• Review this chapter prior to equipment installation.• Review any government and local codes applicable to this installation.• Read the instructions in Chapter 3 before operating the equipment.

Site SurveyPowerwave recommends that a site survey be performed prior to equipment ordering or installation to reduceor eliminate installation and turn-on delays. Note power plant capacity, cooling, RF/AC cabling/breakerrequirements, clearances for proper cooling airflow and maintenance access. System dimensions and weightsare listed in Chapter 5, Table 5-2.

Unpacking and InspectionPerform the steps in Table 2-1 to unpack and inspect the Outdoor System (OS).

If the equipment is damaged, a claim should be filed with the carrier when the extent of any damage isassessed. Contact the factory for a return material authorization (RMA). Refer to Chapter 4.

NOTE: This system must be populated only with G3L-1929-160-001 or G3L-1929-120-001 amplifiers. Installing other amplifiers will void the warranty.

Electrical Service RecommendationsThe base station AC supply to each OS should have a single phase UL listed AC circuit breaker rated at least30 amps. The AC supply also requires UL listed external surge protection rated 2500 Vpk or less for 150 to 300VAC mains installed in accordance with Article 285 of ANSI/NFPA or applicable local codes.

Table 2-2 lists the OS AC and DC current loads.

Table 2-1. Unpacking and Inspection Instructions

Step Action

1 Open the containers and carefully remove the cabinet, MCPAs and modem

2 Visually inspect the outdoor system for shipping damage. Check for evidence of water damage, bent or warped chassis, loose screws or nuts, or extraneous packing material in connectors. Inspect the equipment in the presence of the delivery person if possible

OS-1991 Installation Instructions

.

Installation InstructionsCAUTION: After commissioning, ensure that all power cable and control cables are properly sealed to preventmoisture and contaminants from entering the cabinet.

The outdoor system is designed for installation in an exterior location. The outdoor system must be installed ina designated location that permits access to the lower rear of the cabinet for connection of AC power, RF, andalarm cables. In hot climate environments, shading of the outdoor system is recommended to reduce externalheating of the cabinet.

Verify sufficient space is available in front of the cabinet to remove and replace the MCPA and rectifiermodules and allow free movement of ambient air through the front panel air intake and rear panel exhaustvents. The front door must swing open at a 135 degree angle to allow removal of the MCPAs. Cabinets musthave at least 11 inches clearance from the mounting surface if mounted on the left side (facing unit) to allow fordoor swing. Recommended minimum clearances for the front of the cabinet is 36 inches and 20 inches for therear of the cabinet. Refer to Tables 2-3 and 2-4 respectively for the materials and tools required for a typicaloutdoor system installation. Refer to Chapter 5 for system dimensions and typical mounting examples.

* Specific requirements depending on application.

Modem Install the modem in the bay to the left of the UCM as shown in Figure 2-3. Tighten the thumbscrews to securethe modem. If the system consists of more than one cabinet, additional cabinets may be daisy-chained to thefirst sector by connecting the respective RS485 cable from the other cabinet(s) to the modem connectionshown in Figure 2-4. Wiring examples are shown in Figure 2-5. The modem connector accommodates 28-16AWG wire. Via the UCM, each booster wired on the modem bus must have a unique address.

The modem can be installed in any booster system. The only criteria is that any booster on the modem busneeds a unique bus address. The address does not have to be associated with a sector.

Form-C AlarmsThe Form-C alarm connections are made at the terminal block located at the rear of the UCM. The contactsaccept a 28 - 16 AWG wire. The alarm cable connection is shown in Figure 2-4 and the alarm wiring and relayconditions are listed in Table 2-8.

The Form-C alarm interface should be utilized in conjunction with the modem alarm reporting in the event of amodem failure. Under normal modem applications, the Form-C interface is forced to a no alarm stateunconditionally. If the UCM cannot maintain communication with the modem, a major alarm is asserted and theForm-C alarms are activated to report alarm states.

The minor, major, critical/bypass, and intrusion alarms are defined as follows:

Minor (Alarm0) Any cabinet fan fault.

Major (Alarm1) MCPAs are faulted but one is still active, RX0 or RX1 is faulted but not both, any rectifier fault, an external alarm other than “External Alarm1 AND External Alarm3,” or no communication with the modem.

Connect the Form-C alarms as instructed in Table 2-7.

Critical/Bypass (Alarm2)

All vacant MCPA channels and/or inserted MCPAs are disabled, all active RX channels are faulted, “External Alarm1 AND External Alarm3” faults, the +5V external supply for the RFCU has faulted, or the displayed gain is less than zero resulting in a bypass. A fault causing a critical alarm shuts down the system and requires trou-bleshooting before the system can be brought on-line. Bypass - any time there is a critical fault reported on the Form-C terminal, the booster is in bypass mode.

Intrusion (Alarm3) Front and/or rear cabinet door is open.

Table 2-7 Form-C Alarms Connection Procedure

Step Action

1 To install the appropriate wiring and ease the wiring installation, disconnect the terminal block from the booster.

2 Strip wiring insulation approximately 7 mm (0.3 in).

3 Use a slotted screwdriver with a maximum width of 0.100 inches to back out terminal screws enough to allow wire insertion.

4 Insert stripped wire into terminal and tighten set screw a maximum of 2-inch pounds.

TMA Configuration - UCM

See Figure 3-4

NOTE: These configurations enable DC voltage at antenna ports and enable RX fault monitoring. Each Rx channel sources +12 V at 500 mA maximum. Any current less than 40mA will generate a LO CURRENT fault. Any current greater than 150mA will generate a HI Current fault. Any current greater than 500 mA will disable the DC source for that channel and generate a HI CURRENT fault.A HI CURRENT condition attempts to auto-recover every five minutes by enabling the DC to Rx channel. If fault condition is cured, alarm clears and source remains on. If fault is present, there is no change in sta-tus.

CAUTION: This parameter sources +12 V at 500 mA maximum to antenna ports. Caution should be used if antenna ports are connected to test equipment with 0 VDC tolerance.To prevent a short circuit and alarm situation, all antenna port connections must be complete prior to enabling TMA DC supplies.

IntroductionThis chapter provides periodic maintenance and removal and replacement procedures for the OS-1991Outdoor MCPA System.

Periodic MaintenanceSuggested periodic maintenance requirements are listed in Table 4-1.

WARNING: Wear proper eye protection to avoid eye injury when using compressed air.

CAUTION: Use only dry compressed air when cleaning the OS. Do not use pressure washers.To ensure proper cooling and prevent MCPA over temperature shutdown, one of the two booster doors must be closed and secure at all times.

NOTE: Do not break the seals on equipment under warranty or the warranty will be null and void. Do not return equipment for warranty or repair service until proper shipping instructions are received from the fac-tory.

Cleaning Air Inlets/Outlets/FilterThe air inlets and outlets should be cleaned during periodic site maintenance. If the equipment is operated in aheavy industrial or severe dust environment, the inlets and outlets should be cleaned as necessary. Coolingefficiency can be reduced if dust and dirt are allowed to accumulate. Remove the panel and, using eithercompressed air or a brush with soft bristles, loosen and remove accumulated dust and dirt from the air inletand outlet panels. Replace the panel when cleaned.

The air filter, located in the front panel, also must be removed and cleaned using compressed air. Refer toParagraph Air Filter Cleaning for filter cleaning and replacement instructions.

Table 4-1 Periodic Maintenance

Task Interval Action

Cleaning:

Filter 12 months Inspect and clean air filter.

Air Vents During periodic site maintenance

Inspect and clean inlet and outlet air vents. If equipment is operated in a dusty or industrial environment, inlets and outlets should be inspected more often.

Inspection:

Cables and Connectors

During periodic site maintenance

Inspect signal and power cables for frayed insulation. Check RF connectors to ensure tightness.

044-05307 Rev A 4-1

OS-1991 Troubleshooting

TroubleshootingNote the status of the alarms on the front panels of the rectifier assembly, the MCPA and the UCM. Check faultdisplays on the UCM using the check sequences in Figures 3-2 through 3-4, or by using the web page with theEthernet connection. Contact your field representative or factory if troubleshooting does not resolve theproblem.

The UCM main status menu details the status of the booster. The main menu displays one of the following:

The SYSTEM OK display is normal. If alarms are present, the main menu displays the most severe status.Using the Down and UP keys display the list of faults starting from the most recent. The last display is thealarm history. Using the Right key displays past faults in the order of occurrence, storing up to 10 events. Thelast event is an option to clear the alarm history buffer. Refer to Chapter 3.

Prior to troubleshooting, verify the following:

Rectifier FaultIf a rectifier module is faulted, but no replacement is available, the fault can be masked via the UCM to clearthe related alarm. If rectifier fault reporting is disabled, installing a new rectifier module automatically enablesreporting after two minutes of installation.

Disable the rectifier fault reporting as follows: Refer to Figure 3-5

.

Fan FaultIf a fan is faulted and no replacement is available, the fault can be masked via the UCM. Masking the faultstops the UCM from reporting a minor alarm. If fan fault reporting is disabled, installing a new fan automaticallyenables reporting after two minutes of operation. The UCM display informs which fan is faulted as follows:

❑ SYSTEM OK - No faults or alarms❑ MINOR❑ MAJOR❑ CRITICAL/BYPASS❑ SLEEP MODE - Only applicable to constant gain mode.

❑ Outdoor system receiving specified power from base station.❑ All RF connections are connected properly and are not loose or damaged.❑ All appropriate subassemblies are present inside cabinet.
