2 BTS3900C Monitoring System

The BTS3900C monitoring system enables monitoring of all boards and components in the

cabinet. If any board or component is faulty, an alarm is automatically reported. The UPEU and

UEIU in the BBU or the RRU collects monitoring signals from boards and components to

achieve environment monitoring of the BTS3900C.

3 Appearance of the BTS3900C

The BTS3900C is a white cabinet, consisting of an Outdoor Mini Box (OMB) cabinet and an

RRU subrack.

4 Structure of the BTS3900C

The BTS3900C has two types of cabinets: the BTS3900C AC cabinet and BTS3900C DC

cabinet. The BTS3900C consists of the BBU, RRU, DCDU-03B (for the BTS3900C DC

cabinet), AC/DC power equipment (for the BTS3900C AC cabinet), monitoring board, and fans.

5 BTS3900C ComponentsThe BTS3900C components are the BBU, RRU, HEUA, DCDU-03B, AC/DC power equipment,

AC surge protection box, fans, and sensors.

6 BTS3900C Cables

The BTS3900C cables are the PGND cable, power cable, transmission cable, signal cable, and

RF cable.

The BTS3900C monitoring system enables monitoring of all boards and components in the

cabinet. If any board or component is faulty, an alarm is automatically reported. The UPEU and

UEIU in the BBU or the RRU collects monitoring signals from boards and components to

achieve environment monitoring of the BTS3900C.

2.1 BBU Monitoring Port

The BBU houses 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.

2.2 Monitoring Principles of the CabinetsThe BTS3900C cabinet is monitored by various boards. The boards collect alarms from sensors

and fans, andthen transmit the alarm signals to the MON port on the BBU through the RS485

serial bus. In this manner, the boards monitor the cabinet.

5BTS3900C ComponentsAbout This Chapter

The BTS3900C components are the BBU, RRU, HEUA, DCDU-03B, AC/DC power equipment,

AC surge protection box, fans, and sensors.

5.1 BBU3900

This section describes the appearance, DIPswitch, and LEDs of the BBU3900. It also describes

the configurations, functions, and ports of the boards and modules on the BBU3900.

5.2 RRU

The BTS3900C can be configured with the RRU3804, RRU3801E, RRU3806 or RRU3801C.

The RRU is described interms of the appearance, LED, and panel.

5.3 HEUA

The Heat Exchange Unit type A (HEUA) provides power for the fan assembly, monitors the

status of the fan assembly, collects the cabinet environment monitoring information and power

surge protection alarm information, and reports the collected information to the BBU.

5.4 DCDU-03B/DCDU-03C

The Direct Current Distribution Unit-03 (DCDU-03B/DCDU-03C) supplies DC power to each

component in the cabinet. The height of the DCDU-03B/DCDU-03C is 1 U. It can be classified

into the DCDU-03B and DCDU-03C according to the configured circuit breakers and application

scenarios. The two models have the same exterior and engineering specifications.

5.5 AC/DC Power Equipment

The AC/DC power equipment consists of a 4815 power system and a DC power distribution

box with two outputs. The equipment leads 220 V AC input power into the cabinet, converts the

220 V AC power into -48 V DC power through the AC/DC PSUs, and supplies -48 V DC power

to the components in the cabinet.

5.6 AC Surge Protection Box

The AC surge protection box provides surge protection for the input AC power.

5.7 BTS3900C Fans

The BTS3900C fans enable the ventilation and heat dissipation for the cabinet. The fans consist

of the inner air circulation fan and outer air circulation fan.

This section describes the appearance, DIP switch, and LEDs of the BBU3900. It also describesthe configurations, functions, and ports of the boards and modules on the BBU3900.

5.1.1 Exterior of the BBU3900

The BBU3900, which has a case structure, is 19 inches wide and 2 U high.

Context

The dimensions of the BBU3900 are 86 mm x 442 mm x 310 mm (3.39 in. x 17.4 in. x 12.2 in.)

(H x W x D), as shown in Figure 5-1.

Figure 5-1BBU3900

Procedure

Step 1 The Electronic Serial Number (ESN) is a unique identifier of a Network Element (NE). Recordthe ESN for later commissioning of the base station before installation.

l The ESN of the BBU is recorded in V200R013 and V200R014. For details operations, seesubstep Step 1.1.

l The ESN of the BBU is recorded in V200R010, V200R011, and V200R012. For detailed

operations, see substep Step 1.2.

1. Record the ESN on the BBU.

l If there is not a label on the FAN unit of the BBU, you must record the ESN and site

information that is printed on a mounting ear of the BBU. Figure 5-2shows the position

of the ESN.

l If there is a label on the FAN unit of the BBU, the ESN is printed on the label and a

mounting ear of the BBU. In this case, you must take the label and record the site

information on the side labeled Site, as shown in Figure 5-3.

The Universal Power and Environment Interface Unit (UPEU) for the BBU3900 converts -48

V DC or +24 V DC power into +12 V DC.

Panel

The UPEU is classified into three types: Universal Power and Environment Interface Unit Type

A (UPEUa), Universal Power and Environment Interface Unit Type B (UPEUb), and Universal

Power and Environment Interface Unit Type C (UPEUc). The UPEUa and UPEUc convert -48

V DC power into +12 V DC, and the UPEUb converts +24 V DC power into +12 V DC. Figure

5-15, Figure 5-16, and Figure 5-17show the panels of the UPEUa, UPEUb, and UPEUc,

respectively.

The UPEUc has a silkscreen "UPEUc" indicating its board type on it, whereas the UPEUa and UPEUb donot have such a silkscreen indicating their board types. The UPEUa and UPEUb, however, can be

distinguished by the silkscreens "-48 V" and "+24 V" on them.

Functions

The UPEU performs the following functions:

l Converts -48 V DC or +24 V DC power into +12 V DC, which is the operating voltage of

the boards.

l Provides two ports with each transmitting one RS485 signal and two ports with each

transmitting four Boolean signals. The Boolean signals can only be dry contact or Open

Collector (OC) signals.

NOTE

After the UPEUc is replaced by the UPEUa, the base station power consumption data monitored by the

network management system will change. The power consumption data does not only depend on the output

power but also on the data collection method. The UPEUc and UPEUa use different methods for power

consumption data collection. Therefore, the decrease in the power consumption shown in the network

management system after the UPEUc is replaced by the UPEUa does not necessarily reflect the actualdecrease of power consumption.
