Issue 03 (2010-01-20)


2 BBU3900 Equipment

The FAN is the fan unit of the BBU3900. The FAN controls the fan speed, detects the temperature of the fan board, and dissipates the heat in the BBU. 2.2.6 UPEU This describes the Universal Power and Environment Interface Unit (UPEU) board. It is a mandatory board of the BBU3900 that converts -48 V or +24 V DC to +12 V DC. 2.2.7 UEIU This describes the Universal Environment Interface Unit (UEIU) of the BBU3900. The UEIU transmits monitoring and alarm signals from the external devices to the main control and transmission unit. 2.2.8 UTRP This describes the Universal Transmission Processing unit (UTRP) board. As the transmission extension board of the BBU3900, the UTRP provides eight E1s/T1s, one unchannelized STM-1/ OC-3 port, four electrical ports, or two optical ports. 2.2.9 USCU This describes the Universal Satellite card and Clock Unit (USCU). 2.2.10 UBRI The Universal Baseband Radio Interface Board (UBRI) provides extended CPRI optical or electrical ports to implement convergence, distribution, and multi-mode transmission on the CPRI. 2.2.11 Optical-to-Electrical Conversion Module The optical-to-electrical conversion module is optional, which converts the SFP optical port into the RJ-45 port.

2.2.1 Board Configuration of the BBU3900 This describes the board configuration principles of the BBU3900 GSM, BBU3900 GU, and BBU3900 UMTS.

3.3 BBU Power Cable This describes the power cable. Either -48 V power cable or +24 V power cable can be used, depending on the power input.

Structure When the BBU is installed in a cabinet with a certain type of power supply, the type of the BBU power cable depends on the type of the cabinet. When the power supply is DCDU or PDU, the BBU power cable has a 3V3 connector at one end and bare wires at the other end. Based on the connector of the power distribution device, appropriate terminals are added to the bare end on site. Figure 3-2 shows the power cable by taking OT terminals at the bare end as an example. Figure 3-2 BBU power cable - 1

NOTE

There are two -48 V power cables with one in blue and the other in black. The +24 V power cables have the same structure to the -48 V power cables, but they differ in color. The +24 V power cable are in red and black.

When the power supple is EPS, the BBU power cable has a 3V3 connector at one end and easy power receptacle (pressfit type) connector at the other end. Figure 3-3 shows the structure of the power cable.

Auxiliary Devices of the BBU3900

About This Chapter This describes the auxiliary devices of the BBU3900. The devices consist of the EMUA and SLPU. 4.1 EMUA The Environment Monitoring Unit (EMUA) monitors the internal environment of the cabinet and reports related alarms. 4.2 DCDU-03 The Direct Current Distribution Unit-03 (DCDU-03) supplies DC power to each component in the cabinet. The height of the DCDU-03 is 1 U. It can be classified into the DCDU-03B and DCDU-03C according to the configured MCBs and application scenarios. The two models have the same exterior, engineering specifications, and ports. 4.3 SLPU The signal lightning protection unit (SLPU), which can be optionally configured with the UFLP, UELP, or USLP2, provides the signal surge protection.

4.1 EMUA The Environment Monitoring Unit (EMUA) monitors the internal environment of the cabinet and reports related alarms. The EMUA is connected to the main equipment through alarm cables, monitoring the environment information of the equipment room and cabinet. The EMUA monitors the following items: l

Environment such as the temperature and humidity, water damage, and smoke

l

Intrusion status through the infrared equipment and door status sensor

l

Power distribution

For details about the structure and functions of the EMUA, see the EMUA User Guide.

4.2 DCDU-03 The Direct Current Distribution Unit-03 (DCDU-03) supplies DC power to each component in the cabinet. The height of the DCDU-03 is 1 U. It can be classified into the DCDU-03B and DCDU-03C according to the configured MCBs and application scenarios. The two models have the same exterior, engineering specifications, and ports.

Exterior Figure 4-1 shows the DCDU-03. Figure 4-1 DCDU-03

Functions The DCDU-03 provides nine -48 V DC outputs and different MCB configurations to meet the power distribution requirements of the scenarios of distributed and separated base stations. Table 4-1 describes the DC power distribution functions of the DCDU-03.
