Installing the BBU3900
Determine whether to reversely install the mounting ear according to the space
available at the installation site and the installation mode of the equipment in the
cabinet.
Remove the screws and mounting ears on both sides of the BBU3900.
Reinstall the mounting ears.
Hold the BBU3900 with your hands
and align the holes for mounting
ears with the cabinet installation
holes.
Slide the BBU3900 into the cabinet
slowly along the guide rails.Fix the BBU3900 in the cabinet by
using four panel screws.
a Installing the BBU3900 in the 19-Inch Cabinet

To provide -48 V DC power supply for the site, you need to install the DCDU-03C. TheDCDU-03C converts one -48 V DC power input to multiple 48 V DC power outputs for thebase station. The APM200 needs to be installed only when there is only 220 V AC powersupply at the site. The APM200 converts 220 V AC power input to multiple -48 V DC poweroutputs for the base station. Ensure that the power distribution equipment such as the APM200 and DCDU-03C has an
independent power switch to control the power-on and power-off of each BBU and RRU. When the 2T2R is used, the remaining N-type connectors are protected by waterproof caps.

The PGND cable of the BBU isyellow-green or green. The sectional
area of the PGND cable is 6 mm2
(10AWG).The PGND cable is
connected to the BBU through a OT
terminal or a two-hole OT terminal
(M4) and to the grounding bar
through an OT terminal. The PGND
cable of the BBU should be created
at the site.

e Installing the GPS Clock Signal Cable
When the BBU3900 is configured with a USCU, the GPS clock signal cable is connected to
the GPS port on the USCU. When the BBU3900 is not configured with a USCU, the GPS
clock signal cable is connected to the GPS port on the BMPT.
ProtectSurge
When the BBU is installed in a 19-inch cabinet, ground the surge protector. The
grounding cable should not be longer than 300 mm, and the cross-sectional area of thegrounding cable is 6 mm2. The grounding cable is terminated with OT terminals on both
ends.

RF jumper
Before installing the RF jumper,
measure the VSWR of the antenna
system. For details, see "Measuring
the VSWR of the Antenna System"
on P21.
You need take
insulation and
waterproof
measures only for
the RF jumpers
connected to an
outdoor RRU.
Connection Relation between the 4T4R RRU and Four-port Antenna
Identify the RF ports with their silkscreens,
and connect the jumpers according to the
connection relation shown in the figure
above.

Installing the Outdoor Cable Transfer Box
Measuring the VSWR of the Antenna System
When the distance between the RRU and the DCDU-03C orAPM200 ranges from 60 m to 180 m, install an outdoor cabletransfer box at the RRU.
The length of the cable which between the outdoor cabletransfer box and the RRU is 3 m to 5 m.
Measure the VSWR of the antenna system using theBroadband Site Master.
Measure the VSWR in the position where the antennasystem is connected to the RF port of the RRU.
Never connect an antenna system with a VSWR of1.5 or higher to the RRU.
