2 Matched DBS3900 Cabinets

About This Chapter

The DBS3900 consists of the BBU3900 and different types of RRUs. The RRUs can be installedremotely so that the DBS3900 can be used in various scenarios outdoors. To meet thecomplicated and various environments outdoors, Huawei provides multiple cabinets withdifferent functions for the distributed base station. The cabinets are the APM series cabinets(such as APM30, APM30H (Ver. A), and APM30H (Ver. B)), TMC series cabinets (such asTMC, TMC11H (Ver.A), and TMC11H (Ver. B)), and battery cabinets (such as the BBC,IBBS200D, and IBBS200T). Figure 2-1 shows the exteriors of the cabinets.

Figure 2-1 Exteriors of the cabinets

The APM series cabinets are the power cabinets used for Huawei radio communication productsoutdoors. The APM series cabinets provide AC and DC power distribution functions fordistributed base stations and separate base stations used outdoors and also provide space forcustomer equipment.

The APM30 is different from the APM30H (Ver. A) in heat dissipation and monitoring modes.The APM30 uses the breathable film and fans for heat dissipation, and the APM30H (Ver. A)uses the core of the heat exchanger and inner and outer air circulation fans for heat dissipation.The APM30 is configured with the APMI and AFMU for environment and power monitoring,and the APM30H (Ver. A) is configured with the HEUA for fan monitoring and alarm reporting.

The APM30H (Ver. A) is different from the APM30H (Ver. B) in monitoring and powerdistribution modes. The APM30H (Ver. A) is configured with the HEUA for fan monitoringand alarm reporting, and the APM30H (Ver. B) is configured with the CMUA as the central

monitoring unit. The APM30H (Ver. A) is configured with the PDU as the power distributionunit, and the APM30H (Ver. B) is configured with the EPS subrack as the power distributionunit. In addition, the APM30H (Ver.B) is configured with the Electronic Labeling Unit (ELU)for automatic cabinet type reporting.

The TMC series cabinets are the transmission cabinets used for Huawei radio communicationproducts outdoors. The TMC series cabinets provide DC power distribution functions fordistributed base stations and separate base stations and also provide space for customerequipment.

The TMC is different from the TMC11H (Ver. A) in heat dissipation and monitoring modes,and the TMC11H (Ver. A) is different from the TMC11H (Ver.B) in monitoring mode. TheTMC uses the breathable film and fans for heat dissipation, and the TMC11H (Ver. A) uses thecore of the heat exchanger and inner and outer air circulation fans for heat dissipation.

The BBC, IBBS200D, and IBBS200T are the battery cabinets used for Huawei radiocommunication products outdoors. The cabinets provide space for batteries, which provide long-duration backup power for the distributed base station and separate base station. The IBBS200Dis different from the IBBS200T in the configurations of the modules in the cabinets. For details,see 2.1 Module Configurations in the DBS3900 Cabinets.

APMNOTEFor details about the functions of the DBS3900 cabinets, see the APM30 User Guide, APM30H UserGuide, APM30H&TMC11H&IBBS200D/T User Guide.

The APM series cabinets are divided into the APM30, APM30H (Ver. A), and APM30H (Ver.B) based on different versions. Figure 2-2 shows the module configurations in the APM seriescabinets.

3 Configurations of the Matched Cabinets

When the DBS3900 is installed outdoors, multiple matched cabinets must be configured to meetthe backup power, transmission, and capacity requirements. Different types of cabinet can becombined to form the DBS3900, providing multiple outdoor solutions.

Cabinet Configuration PrinciplesNOTEIn the following description, the APM is the APM30, APM30H (Ver. A), and APM30H (Ver.B). The TMCfalls into the categories of the TMC, TMC11H (Ver. A), and TMC11H (Ver. B).

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.

l A single APM30/APM30H (Ver. A) can be configured with only a single TMC/TMC11H(Ver. A) and a maximum of one IBBS200T.

l A single APM30H (Ver. B) can be configured with only a single TMC11H (Ver. B) and amaximum of two IBBS200Ds/IBBS200Ts.

l A maximum of six power cables and twelve 2-core optical cables can be led out from asingle 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 The BBC/IBBS200D/IBBS200T can be stacked on each other or placed under a TMC.When the BBC/IBBS200D/IBBS200T is stacked with the TMC, the BBC/IBBS200D/IBBS200T is stacked on the TMC.

l If auxiliary cabinets such as the battery cabinet or TMC are required during an initial siteconstruction, the auxiliary cabinet is positioned on the left, and the primary cabinet ispositioned on the right. If both the battery cabinet and the TMC are required, the batterycabinet is positioned on the left of the primary cabinet, and the TMC is stacked on thebattery cabinet or positioned on the left of the battery cabinet.

l Space must be reserved during an initial site construction for future capacity expansion. Inthe capacity expansion scenario, the original cabinets are not relocated while new cabinetsare added only from left to right. In a special scenario, new cabinets can be added fromright to left.
