INSTALL THE RF MODULE(S)

ThefollowingsectionsguideyouthroughtheinstallationofanRFModuleintoaRemoteUnitchassis.Theprocess

toinstallthefourdifferenttypesofRFModulesisbasicallythesame;however,differencesarenotedandshould

befollowed.

NOTE: In the following steps, the RF cables and connectors are referred to as MOD N TX0/RX0 and as MOD N

TX1/RX1 where N equals A, B, C, or D.

NOTE: When installing RF Modules, populate the RF Modules from highest frequency band to lowest within the

Remote Unit chassis. Likewise, for power output, populate from the bottom bay to the top; higher

output to lower output. That is, for a deployment with 2100 40W, 1900 40W, 850 20W and 700 20W

MIMO, install the RF Modules as follows:

• 2100 40W RF Module in Bay A

• 1900 40W RF Module in Bay B

• 850 20W RF Module in Bay C

• 700 20W MIMO RF Module in Bay D.

SAFETY PRECAUTIONS

CAUTION! This is restricted access equipment and only qualified service personnel should service and operate this

equipment using appropriate tools.

CAUTION! 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.

CAUTION! Always allow sufficient fiber length to permit routing of patch cords and pigtails without severe bends.

Fiber optic patch cords or pigtails may be permanently damaged if bent or curved to a radius of less than

2 inches (5.1 cm).

CAUTION! Exterior surfaces of the Prism Remote Unit may be hot. Use caution during servicing.

CAUTION! Service personnel must confirm that the perimeter gasket and door-to-door gaskets are in place when

closing the Remote Unit doors after servicing.

CAUTION! This equipment uses a Class 1 Laser per 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. An optical power meter should be used to

verify active fibers. A protective cap or hood MUST be immediately placed over any radiating

transceiver or optical fiber connector to avoid the potential of dangerous amounts of radiation

exposure. This practice also prevents dirt particles from entering the adapter or connector.

CAUTION! This system is an RF Transmitter and continuously emits RF energy. Maintain 3 foot (91.4 cm) minimum

clearance from the antenna while the system is operating. Wherever possible, shut down the RAN

before servicing the antenna.

Install the RF Module(s) INSTALL THE RF MODULE(S) The following sections guide you through the installation of an RF Module into a Remote Unit chassis. The process to install the four different types of RF Modules is basically the same; however, differences are noted and should be followed. NOTE: In the following steps, the RF cables and connectors are referred to as MOD N TX0/RX0 and as MOD N TX1/RX1 where N equals A, B, C, or D.

Install the RF Module(s) GUARD AGAINST DAMAGE FROM ELECTRO-STATIC DISCHARGE CAUTION! Electro-Static Discharge (ESD) can damage electronic components. To prevent ESD damage, always wear an ESD wrist strap when working with a Prism Remote Unit or when handling any of its components— including the RF Modules. Connect the ground wire on the ESD wrist strap to an earth ground source before touching the Prism Remote Unit or any of its components.

Install the RF Module(s) REMOVE RELEASE LINERS FROM THE RF MODULE NOTE: Release Liners are present on front and back of new modules. 1 Open the Remote Unit enclosure. 2 Remove release liners, if present, from the thermal pads on the RF Module prior to installing the module into the Remote Unit chassis. CAUTION! The thermal pads are very sensitive to mishandling—do not nick, scratch, or ding them.
PAGE 4
Install the RF Module(s) For HDM RF Modules, the thermal pads are located as listed below and as shown in Figure 20. • one pad for each Rx and Tx board • one large pad over the DPM • one for each Power Amplifier (PA), which is on the bottom of the HDM RF Module.

Install the RF Module(s) DUAL-BAY MODULES ONLY—REMOVE THE MODULE BAY SHELF FOR DUAL-BAY RF MODULES ONLY. If you are installing a Dual-Bay RF Module, you must remove a module bay shelf from the PRU chassis to accommodate the module’s size. (For further information, see Table 16 on page 27.) Remove the shelf as appropriate for the RF Module: • When installing in the A and B Bays, remove the Module B Bay Shelf. • When installing in the C and D Bays, remove Module D Bay Shelf.

Install the RF Module(s) POWER ON THE RF MODULE(S) AND THE PRISM REMOTE UNIT 1 If necessary, power up the Remote Unit by turning its AC or DC power switch to On. 2 Ensure that the external Status LED on the bottom of the Remote Unit goes off.
PAGE 28
Install the RF Module(s) 3 Follow the rules listed below to toggle the Power switch that corresponds to each RF Module to its ON position. • For Dual-Band Dual-Bay RF Modules, use the Power switch for the lower module. For example, to power up a Dual-Bay RF Module in combined bays C+D in a Quad-Bay chassis, turn ON DC Power switch for Mod C; leave the DC Power switch for Mod D OFF. • A Legacy Dual-Bay 40W RF Module uses the Power Supplies in both bays.

Install the RF Module(s) CLOSE THE REMOTE UNIT DOOR AND SOLAR SHIELD 1 Do not slam the door to close it—gently swing the door shut and press it firmly closed. 2 Slowly close each door latch in a smooth fluid motion—do not allow the door latches to snap closed. For best results, starting with the top latch and working down to the bottom latch, use a flat-head screwdriver to close each latch as shown below. 3 Do not slam the Solar Shield to close it—gently swing it shut and press it firmly closed.

Fan Module Maintenance FAN MODULE MAINTENANCE Continuous airflow to cool the PRU is provided by the Fan Module that is mounted on the top of the PRU chassis. The cooling fans pull the heated air up from the chassis. The heated air is then exhausted through the vent openings at the top of the chassis. This constant movement of air requires that the Fan Module be placed on a maintenance schedule. ANNUAL FAN CHECKUP CAUTION! A mechanical hazard exists due to rotating fan blades.
PAGE 36
Fan Module Maintenance Use the following procedure to remove and replace the PRU Fan Module: 1 Read all instructions and procedures of this section prior to beginning work to replace Fan Module. 2 Order a Prism Remote Unit Fan Replacement Kit, catalog number FWP-RUFAN001. 3 Notify the NOC or alarm monitoring system operator that the Fan Module is being replaced, which will generate fan and power alarms for the affected PRU. 4 Power down the PRU and wait until the fans spin down to a stop.
PAGE 37
Fan Module Maintenance 9 Remove the old Fan Module from the PRU: a The Fan Module has two keyhole rivets that extend through their designated slots into the sheet metal frame. To disengage the Fan Module keyhole rivets, slide the Fan Module forward approximately 1/4-inch. b Lift the Fan Module straight up to remove it from the PRU chassis.
