Matched DBS3900 Cabinets
About This Chapter The DBS3900 consists of the BBU3900 and different types of RRUs. The RRUs can be installed remotely so that the DBS3900 can be used in various scenarios outdoors. To meet the complicated and various environments outdoors, Huawei provides multiple cabinets with different 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 as TMC, 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 products outdoors. The APM series cabinets provide AC and DC power distribution functions for distributed base stations and separate base stations used outdoors and also provide space for customer 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.

3 Configurations of the Matched Cabinets
Configurations of the Matched Cabinets When the DBS3900 is installed outdoors, multiple matched cabinets must be configured to meet the backup power, transmission, and capacity requirements. Different types of cabinet can be combined to form the DBS3900, providing multiple outdoor solutions.
Cabinet Configuration Principles NOTE
In the following description, the APM is the APM30, APM30H (Ver. A), and APM30H (Ver.B). The TMC falls 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 than 12 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 a maximum of two IBBS200Ds/IBBS200Ts.
l
A maximum of six power cables and twelve 2-core optical cables can be led out from a 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
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 site construction, the auxiliary cabinet is positioned on the left, and the primary cabinet is positioned on the right. If both the battery cabinet and the TMC are required, the battery cabinet is positioned on the left of the primary cabinet, and the TMC is stacked on the battery cabinet or positioned on the left of the battery cabinet.
l
Space must be reserved during an initial site construction for future capacity expansion. In the capacity expansion scenario, the original cabinets are not relocated while new cabinets are added only from left to right. In a special scenario, new cabinets can be added from right to left.

Matched DBS3900 Cabinets
About This Chapter The DBS3900 consists of the BBU3900 and different types of RRUs. The RRUs can be installed remotely so that the DBS3900 can be used in various scenarios outdoors. To meet the complicated and various environments outdoors, Huawei provides multiple cabinets with different 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 as TMC, 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.

The APM series cabinets are the power cabinets used for Huawei radio communication products outdoors. The APM series cabinets provide AC and DC power distribution functions for distributed base stations and separate base stations used outdoors and also provide space for customer 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 power distribution modes. The APM30H (Ver. A) is configured with the HEUA for fan monitoring and alarm reporting, and the APM30H (Ver. B) is configured with the CMUA as the central 2-2

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 communication products outdoors. The TMC series cabinets provide DC power distribution functions for distributed base stations and separate base stations and also provide space for customer equipment. 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. The TMC uses the breathable film and fans for heat dissipation, and the TMC11H (Ver. A) uses the core of the heat exchanger and inner and outer air circulation fans for heat dissipation. The TMC is configured with the APMI and AFMU as the monitoring unit, the TMC11H (Ver.A) is configured with the HEUA as the monitoring unit, and the TMC11H (Ver. B) is configured with the CMUA and HPMI as the monitoring unit. In addition, the TMC11H (Ver. B) is configured with the ELU for automatic cabinet type reporting. The BBC, IBBS200D, and IBBS200T are the battery cabinets used for Huawei radio communication products outdoors. The cabinets provide space for batteries, which provide longduration backup power for the distributed base station and separate base station. The IBBS200D is different from the IBBS200T in the configurations of the modules in the cabinets. For details, see 2.1 Module Configurations in the DBS3900 Cabinets.

3 Configurations of the Matched Cabinets
Configurations of the Matched Cabinets When the DBS3900 is installed outdoors, multiple matched cabinets must be configured to meet the backup power, transmission, and capacity requirements. Different types of cabinet can be combined to form the DBS3900, providing multiple outdoor solutions.
Cabinet Configuration Principles NOTE
In the following description, the APM is the APM30, APM30H (Ver. A), and APM30H (Ver.B). The TMC falls 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 than 12 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 a maximum of two IBBS200Ds/IBBS200Ts.
l
A maximum of six power cables and twelve 2-core optical cables can be led out from a 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
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.
