This chapter describes the configuration principles of the boards and modules in the cabinet.
3.1.1 Module Configurations in the Cabinet
The BTS3900 cabinet uses a modular design. The main components of the cabinet are the
BBU3900, RFU, DCDU-01, and fan box. The power equipment (DC/DC) and power equipment
(AC/DC) are optional components of the cabinet.
3.1.2 Board Configuration of the BBU3900
This describes the board configuration of the BBU3900.
3.1.1 Module Configurations in the Cabinet
The BTS3900 cabinet uses a modular design. The main components of the cabinet are the
BBU3900, RFU, DCDU-01, and fan box. The power equipment (DC/DC) and power equipment
(AC/DC) are optional components of the cabinet.
There are three types of BTS3900 cabinets, namely, the BTS3900 (-48 V DC) cabinet, BTS3900

positioned on the right. If restricted by the actual situation in the equipment room, the
primary cabinet can be positioned on the right.
l The BTS3900 (-48 V DC) cabinet, BTS3900 (+24 V DC) cabinet, and BTS3900 (AC)
cabinet support side-by-side installation mode.NOTE
l The primary cabinet is the cabinet that is configured with the BBU.
l The secondary cabinet is the cabinet that is not configured with the BBU.

3.4.2 External Monitoring Port
The monitoring ports are configured on the BBU, EMU, and EMUA for monitoring external
signals of the base station.
The BBU is configured with the UPEU and UEIU for monitoring. Each board has two Boolean
input ports and two RS485 input ports, and each Boolean input port receives four Boolean inputs.
Figure 3-17shows the slot assignment for the UPEU and UEIU.

When two UPEUs are configured in the BBU, the other UPEU is configured in Slot18. The pin assignments
for the wires connected to the monitoring ports on this UPEU are the same as those for the wires connected
to the monitoring ports on the UEIU.
The EMU and EMUA are used for environment monitoring indoors and outdoors respectively.
The EMU and EMUA enable the monitoring of analog values and Boolean signals with the portfor monitoring analog inputs, port for detecting the Boolean inputs, and port for controlling the
external Boolean outputs.
l When the base station is deployed indoors, the EMU is configured for monitoring the analog
values and Boolean signals. For details about the monitoring ports on the EMU, see
HUAWEI QCKG1EMU User Guide.
l When the base station is deployed outdoors, the EMUA is configured for monitoring the
analog values and Boolean signals. For details about the monitoring ports on the EMUA,

NOTE
l If backup power is required for the BBU, two UPEUs are configured instead of UPEU+UEIU.
l If the BTS3900 is configured with three cabinets, a UEIU is configured for monitoring the RS485
signals. Therefore, another UEIU is not required for monitoring the dry contact alarms.l The analog values can be monitored only by the EMU.
l The EMU with sensors can be configured according to site requirements.
