2.3 Usage Scenarios of the APM30 and APM30H (Ver.A)In outdoor scenarios, multiple cabinets and different configurations of cabinets can be used fora DBS3900 to meet various requirements for power backup, transmission, and capacity.

Cabinet Configuration PrinciplesNOTEIn this section, the APM is APM30 or APM30H (Ver.A), and the TMC is TMC or TMC11H(Ver.A).

l A single DBS3900 can be configured with a maximum of 12 RRUs. If there are more than12 RRUs, they must be configured in different base stations.

l A single APM or TMC can provide power to a maximum of six RRUs.



29

l A single APM supports only one TMC and a maximum of one integrated battery backupsystem with TEC (IBBS200T). TEC is short for thermoelectric cooling unit.

l A maximum of six power cables and twelve 2-wire fiber optic cables can be led out froma single APM.

l A single DCDU supplies power to a maximum of six RRUs.l The APM or TMC can be installed on the floor or stacked on the battery cabinet.l A backup battery cabinet (BBC) or IBBS200T can be stacked with a cabinet of the same

type or be stacked under a TMC.l If an extension cabinet such as a battery cabinet or transmission cabinet is required during

an initial site deployment, the extension cabinet is placed on the left, and the basic cabinetis placed on the right. If both an extension battery cabinet and an extension transmissioncabinet are required, the battery cabinet is placed on the left of the basic cabinet and thetransmission cabinet is placed onto the battery cabinet or on the left of the battery cabinet.

l Clearance must be reserved during an initial site deployment for future capacity expansion.In a capacity expansion scenario, the original cabinets are not relocated and new cabinetsare added only to the right of the original cabinets unless they are required to be installedto the left of the original cabinets in exactly the reverse order of the original cabinets.

Requirements of Customer Equipment SpecificationsCustomer equipment to be installed in a Huawei cabinet must satisfy the following requirements:l Dimension requirements (as shown in Figure 2-6):

– The customer equipment must be 19-inch wide, which is the width of the standardequipment.

– The maximum depth of the customer equipment is 310 mm if the equipment supportsnatural ventilation or has air vents on the right and left; the maximum depth of thecustomer equipment is 280 mm if the equipment has air vents in the front and back.

– A maximum cabling pace in front of the panel is 70 mm.l Requirement for air vents:

– If the customer equipment has built-in fans, the fans must have air vents on the rightand left or on the front and back so that wind blows from left to right or from front toback.

– If the customer equipment support natural ventilation, a minimum of 1 U slot must bereserved above and below the slot respectively for dissipation.

l Requirement for temperature– In areas where the highest temperature is or is below 40°C, the customer must be able

to function properly at –10°C temperature or even lower temperature and at 55°C oreven higher temperature.

3.4 Power Distribution Scheme of the APM30 or APM30H(Ver.A)

This section describes the power distribution schemes for a DBS3900 configured with an APM30or APM30H (Ver.A) in the 110 V AC, 220 V AC, and -48 V DC power supply scenarios. APMis short for advanced power module, and APM30H is short for advanced power module with aheat-exchanger cooler.



58

Power Distribution Schemes in the 110 V AC and 220 V AC Power Supply Scenarios

In a 110 V AC or 220 V AC power supply scenario, a power distribution unit (PDU) in theAPM30 or APM30H (Ver.A) converts AC power to DC power and then distributes the power.

The PDU supplies two AC power inputs and ten DC power inputs.

Figure 3-1and Figure 3-2 show the power distribution schemes for the APM30 in the 220 VAC and 110 V AC power supply scenarios. Table 3-15 lists the specifications of the circuitbreakers and fuses in the DBS3900 in the scenarios.

NOTEIn a scenario with a 220 V AC three-phase power supply, the three AC power inputs do not need to beconnected in series using a short-circuiting strip. The power distribution principles for this scenario are thesame as those for the 220 V AC single-phase power supply scenario.

In a scenario with 110 V AC or 220 V AC power supply, the embedded power supply system(EPS) and embedded power subrack unit (EPU) in the cabinet converts AC power to DC powerand distributes the DC power.

The EPS or EPU supplies two AC power outputs:

l One provides AC power for the service outlet unit (SOU).

l One is connected to the junction box on the left of the cabinet, and divided into four ACpower outputs, which are then provided for the heater or heating film.

A power supply unit (PSU) converts the AC power to DC power, which is then supplied to thestorage battery cabinet, transmission cabinet, baseband unit (BBU), remote radio unit (RRU),and other equipment in the DBS3900.

NOTE

When the 220 V AC three-phase power supply is used, the three AC power inputs do not need to beconnected in series using a short-circuiting bar. The power distribution principles for this scenario are thesame as those for the 220 V AC single-phase power supply scenario.

4 DBS3900 Monitoring System

About This Chapter

The DBS3900 monitoring system enables monitoring of all boards and components in thecabinet. If any board or component is faulty, an alarm is automatically reported. The UPEU andUEIU in the BBU or the RRU collects monitoring signals from boards and components toachieve environment monitoring of the DBS3900.

4.1 BBU Monitoring PortThe BBU houses the UPEU and UEIU for monitoring. Each board has two Boolean input portsand two RS485 input ports, and each Boolean input port receives four Boolean inputs.

4.2 Monitoring Schemes of the APM30 or APM30H (Ver.A)The advanced power module (APM30) cabinet and the APM30H (Ver.A) cabinet are monitoredby various boards. The boards manage the cabinet by collecting alarms from components suchas sensors and fans and by using the RS485 serial bus to transmit the alarm signals to the MONport on the baseband unit (BBU). APM30H is short for advanced power module with a heat-exchanger cooler.

4.3 Monitoring Scheme of the APM30H (Ver.B) or APM30H (Ver.C)The APM30H (Ver.B) cabinet and the APM30H (Ver.C) cabinet are monitored by variousboards. The boards manage the cabinets by collecting alarms from components such as sensorsand fans and then using the RS485 serial bus to transmit alarm signals to MON ports on thebaseband unit (BBU).

4.4 Monitoring Schemes for the OMB, IMB03, and IFS06The outdoor mini box (OMB), indoor mini box (IMB03), and the indoor floor installation support(IFS06) are monitored by different boards. The boards or modules report the alarms fromcomponents such as sensors and fans to the baseband unit (BBU).

4.5 Customized Alarm InputWhen an alarm is generated by the customized equipment, the alarm must be reported to theBBU.

5.2.8 UPEUA universal power and environment interface unit (UPEU) for the BBU3900 converts –48 VDC or +24 V DC power into +12 V DC power.

PanelUPEUs fall into three types: universal power and environment interface unit type A (UPEUa),universal power and environment interface unit type B (UPEUb), and universal power andenvironment interface unit type C (UPEUc). The UPEUa and UPEUc convert –48 V DC powerinto +12 V DC power, and the UPEUb converts +24 V DC power into +12 V DC power. Figure5-24, Figure 5-25, and Figure 5-26 show the panels of the UPEUa, UPEUb, and UPEUcrespectively.

NOTEThe UPEUa can be distinguished from the UPEUb by observing the silkscreen on the panel. The silkscreenon the UPEUa is –48V and the silkscreen on the UPEUb is +24V. The UPEUa can also be distinguishedfrom the UPEUc because a UPEUc label is on the UPEUc.



122

FunctionThe UPEU performs the following functions:l Converts –48 V DC or +24 V DC power into +12 V DC power, which is the only operating

voltage of the BBU.l Provides ports for two RS485 signal inputs and eight Boolean signal inputs. The Boolean

signal inputs can be dry contact type or open collector (OC) type.

In a GSM+LTE base station, the route backup transmission mode has the followingcharacteristics:

l IP transmission is applied. The GTMU and LMPT are connected to the transport networkthrough the primary channel.

l The GTMU and the LMPT are interconnected through FE ports on their panels.

l If the primary channel is faulty, the secondary channel takes over. After the primary channelis restored, the route is switched back to the primary one.



190

l The bandwidth required by LTE services is larger than the processing capability of theGSM standard transport network. Therefore, when the secondary channel is used, theQuality of Service (QoS) of only high-priority data flows can be guaranteed.

In a GSM+LTE base station, the following limitations on the route backup transmission modeapply:l The route backup function is not applicable when the base station uses the IP over E1

transmission.l The route backup transmission mode is not applicable on the ports on the UTRPs for GSM

and LTE transmission. It is applicable only on the ports on the GTMU and LMPT panels.l In route backup transmission mode, the FE ports of one type on the GTMU and LMPT
