BBU Hardware Structure
The typical power consumption of the BBU is 50 W.
The BBU is a small box with all the external ports on the front panel.
The BBU3900 boards consist of the BSBC, GTMU, UELP, UPEU and UBFA.
HUAWEI TECHNOLOGIES Co., Ltd. HUAWEI Confidential Page 12
BBU Board--BSBC
The BSBC is the backplane of the BBU. The BSBC provides eight
board slots, two power slots, and one fan slot. The universal BBU sub-rack backplane type C (2U) (BSBC) provides
backplane interfaces for communication between boards and supplies
power for boards. The GTMU is located in slots 5 and 6, slot 7 for a main control board
that supports 3G, and other ports are as common slots.

BBU Board--GTMU
The GSM transmission, timing, and management unit for BBU
(GTMU)
controls and manages the entire BTS. It provides interfaces related to
the reference clock, power supply, OM, and external alarm collection. The GTMU performs the following functions:Controls, maintains, and operates the BTS.Supports fault management, configuration management, performance management, and security management.Supports the monitoring of the fan module and power supply module.Distributes and manages BTS3900 clock signals.Provides clock input for testing.Provides port for terminal maintenance.Supports four E1 inputs.Provides CPRI ports for communication with the RF modules .
HUAWEI TECHNOLOGIES Co., Ltd. HUAWEI Confidential Page 14
BBU Module--UBFA
The universal BBU fan unit type A (2U) (UBFA) communicates with
the
GTMU to regulate the temperature, adjust the fan speed, and report
alarms. The UBFA module is hot swappable.

1s ON, 1s OFF The module is running properly.
Red ON The module is reporting an alarm.
HUAWEI TECHNOLOGIES Co., Ltd. HUAWEI Confidential Page 15
BBU Module--UPEU
The universal power and environment interface unit (UPEU)
supports the –48V/ +24V DC power input, supplies power to the
boards, modules, and fan in the BBU, and provides access to
multiple environment monitoring signals. The UPEU performs the following functions:
Converting -48V or +24V DC to +12V DC that is applicable to the boards.Providing two RS485 signals and eight dry contact alarms.Providing reverse connection protection for power cable connectors.

BBU Board—UELPThe universal E1/T1 lightning protection unit (UELP) provides lightning
protection for four E1/T1 signals.
Port Type Cable Description
INSIDE DB25 male connector
E1 transfer cable of the BBU
Transfers the four E1/T1 signals between the UELP and the GTMU
OUTSIDE DB26 male connector
E1/T1 cables of the BBU
Provides the input and output of the four E1/T1 signals between the BBU and the BSC
The UELP has one DIP switch, which is used to set the impedance on the
E1/T1 port. There are four DIP bits on the DIP switch. DIP Switch DIP Status Description

BBU Cable connection
The BBU3900 cables are classified into the PGND cable, -48VDC
power cable, E1/T1 cable, E1 transfer cable, environment monitoring
signal cable, CPRI signal cable between the BBU and the RRU, and
BBU monitoring signal cable. The cable connection relations of the BBU are as follows:

no output, and fan faults), alarms related to module protection (such
as over-temperature protection, and input over-voltage/under-voltage
protection), and power failure alarm.
Monitors the charging and discharging of the batteries.
The PSU (DC/DC) has the following functions:Converts the +24 V DC power into the -48 V DC power.
Monitors alarms related to module faults (such as output over-voltage,
no output, and fan faults), alarms related to module protection (such

and in the fan box. It can adjust the rotation speed of the fans to
implement ventilation and dissipation for the cabinet.The fan box performs the following functions:
Provides forced ventilation and dissipation for the cabinet.Supports two modes of adjusting the rotation speed of the fans:
adjustment based on the temperature and adjustment controlled by the
central processing unit.Detects the temperature.Communicates with the central processing unit to report alarms and the
adjusted rotation speed of the fans based on the temperature to the
central processing unit.Stops the rotation of the fans when the ambient temperature is low.
