BBU3900

There are three main function modules which relate to hardware installation in BBU front face:

UELP GTMU UPEU


UELP—E1/T1 lighting protection unit

Dip switch

Setting of DIP Bit Description 1 2 3 4

SW1 OFF OFF OFF OFF 120Ω E1 (Used in this project)

Dip switch of UELP (Important)


GTMU--The GSM Transmission, Timing, and Management Unit

Dip switch of GTMU (Important)


UPEU--Universal Power and Environment Interface Unit

The UPEU performs the following functions: Converting -48 V DC to +12 V DC that is applicable to the boards Providing two RS485 signals and eight dry contact alarms Providing reverse connection protection for power cable connectors

1. Will take on site photo in PNG2. Battery installation please refer to the related

document


RRU power cables and fibers will be fixed on the cable tray by cable fixing accessory


RRU Connection of S4 cell


Real connection example of S4 cell--bottom

Jumper cable need connect to ANT TR/RXA in the right side

Introduce sensor and alarm materialsAlarm cable—RJ45 Line cable:

Notes: Crossover line cable will be used at here. The pin assignment should be same with the upside showing. Alarm panel may use DDF box or something else in the same function.

Indoor Scenario


Indoor Scenario description

The differences between indoor and outdoor BTS are: 1. The equipments which under the tower are installed in the BTS

room2. RRU power Cables and fibers will go through switch room window

to RRU and antenna3. Overhead cabling will be used4. Rectifier is PS48300. BBU and RRU will power supplied by PS483005. BBU and DDF box will be installed in one separate 19” rack6. Battery will be install in special battery rack and connect to

PS48300


Indoor Scenario description

The similarities between indoor and outdoor BTS are:

1. All of the installation on the tower is same2. The alarm plan is same Dip switch for BBU and UELP is same requirement


Detail cable connection description in the room Will on site take photo to describe







Swap ScenarioSwap Scenario

Swap scenario is basic same with installation new site:

1. Fellow layout, install all of the under tower equipments whatever indoor or outdoor

2. Install RRU, RRU power cables and fibers3. Install new antenna system4. If the plan is use current site’s old antenna Open the connectors between antennas and ½” jumper cables. Use new ½” jumper cables connect the RRU to antenna

The detail plan will be made with customer on site


Key point for Swap ScenarioKey point for Swap Scenario

1. Need pay more attention to the alive network. Do not shut down, power off any running equipment without customer’s permission.

2. Need confirm whether the old antenna will be used after swap

3. Need confirm how about the old feed cables and antenna after swap

4. Need confirm the swap time schedule







ConclusionConclusion

Good quality and customer’s satisfaction is built by us. Please double confirm the fellows items before leave the site:

1. Check the site with hardware quality installation standard

2. GTMU, UELP, PMU dip switch 3. APM30 inside cable connection4. Alarm cables connection5. Antenna azimuth, down tilt angle
