3.2 BTS3900A Cabinet ConfigurationsMultiple cabinets can be combined and installed for the BTS3900A to meet the requirements ofdifferent RFU configurations, backup power capacity, and transmission space. In addition,different configurations of cabinets can be used for the BTS3900A in the 110 V AC/220 V ACpower supply scenario and -48 V DC power supply scenario.

Cabinet Configuration Principlesl A single BTS3900A can be configured with a maximum of 12 RFUs. That is, more than

12 RFUs must be configured in different BTS3900As.l A single BTS3900A can be configured with a maximum of two RFCs, and the RFCs must

be installed side by side with a default distance of 40 mm.l A single APM30H can be used with a maximum of one RFC and with a maximum of two

IBBS200Ds/IBBS200Ts.l The RFC can be stacked only under the APM30H/TMC11H.

l The IBBS200D/IBBS200T can be stacked only with the IBBS200D/IBBS200T orTMC11H. When the IBBS200D/IBBS200T is stacked with the TMC11H, the TMC11H isstacked on the IBBS200D/IBBS200T.

l If auxiliary cabinets such as the IBBS200D/IBBS200T or TMC11H are required during aninitial site construction, the auxiliary is positioned on the left, and the primary cabinet ispositioned on the right. If both the IBBS200D/IBBS200T and the TMC11H are required,the IBBS200D/IBBS200T is positioned on the left of the primary cabinet, and the TMC11His stacked on the IBBS200D/IBBS200T or positioned on the left of the IBBS200D/IBBS200T.

l Space must be reserved during an initial site deployment 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.

110 V AC/220 V AC Power Supply ScenarioIf 6 to 12 RFUs must be configured for a new site, two APM30Hs must be configured.

Figure 3-9 shows the configurations of the cabinets with different TRX configurations if backuppower is not required.

3.3.2 BTS3900A Power DistributionThis section describes the power distribution schemes used for the BTS3900A cabinets in the110 V AC, 220 V AC, and -48 V DC power supply scenarios.

Power Distribution Scheme in the 110 V AC or 220 V AC Power Supply ScenarioWhen the BTS3900A is supplied with 220 V AC or 110 V AC power, the AC power is convertedto DC power and distributed by the Embedded Power Supply System (EPS) in the APM30H.

After going through the EPS, an AC power input is divided into 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.

The AC power input is converted by PSUs into DC power, which is supplied to the batterycabinet, RFC, TMC11H, and other base station equipment.

Figure 3-14 and Figure 3-15 show the power distribution schemes in the 220 V AC and 110 VAC power supply scenarios. Table 3-13 lists the specifications for the circuit breakers and fusesin the base station in the 220 V AC and 110 V AC power supply scenarios.

NOTE

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

As shown in Figure 3-14 and Figure 3-15, three DC power outputs from the APM30H areprovided to RFC1, RFC2, and TMC11H separately when the BTS3900A uses AC power supply.The RFC provides power supply for the RFUs, fan box, and other components in the cabinetthrough the DCDU-01. The TMC11H provides power supply for the transmission equipment,fan box, and other components in the cabinet through the DCDU-03.

Figure 3-16 shows the power distribution scheme for the RFC and TMC11H. Table 3-14 liststhe specifications for the circuit breakers in the RFC and TMC11H.

Power Distribution Scheme in the –48 V DC Power Supply Scenario

When the BTS3900A uses -48 V DC power supply, the external power supply is connected tothe RFC, forwarded to the DCDU-01, and provided to the RFUs and fan box in the cabinet. Inaddition, the DCDU-01 can provide a DC power of 25 A with a maximum power of 800 W tothe TMC11H. The DCDU-03 in the TMC11H then provides DC power to the BBU and fan.
