The power distribution box is installed in the middle of the cabinet. It transfers and distributes power to the TEC or fan, CCU, and storage batteries.

NOTE

l (1) When a CCU is configured, the ELU is installed in the position illustrated by "6." When no CCU is configured, the ELU is installed in the position illustrated by "5." l (2) When the IBBS700T cabinet is used with an APM30H (Ver.D) cabinet, no CCU is required. When the IBBS700T cabinet is used with a BTS3900AL (Ver.A) or TP48600A-H17B1 cabinet, a CCU is required. l (3) The storage batteries provide current of 300 Ah, 450 Ah, or 600 Ah for a single cabinet and provide current of 150 Ah or 300 Ah for each one in a cabinet combination. l A battery temperature sensor is configured in the cabinet by default. For details about the position of the battery temperature sensor in the cabinet, see Temperature Sensor.

2.2 BTS3900A (Ver.D) Configured with RFUs but Without RRUs When only RFUs are configured, a BTS3900A supports different cabinet configurations in 110 V AC, 220 V AC, or -48 V DC power supply scenarios.

Cabinet Configuration Principles Maximum configuration principles for a single site l

A BTS3900A site can be configured with a maximum of 12 RFUs.

l

A BTS3900A site can be configured with a maximum of two cabinet combinations (one cabinet combination consists of one APM30H and one RFC). The two cabinet combinations must be installed side by side with a clearance of 40 mm (1.57 in.) between them.

l

When a site is configured with more than six RFUs and only one IBBS200D or IBBS200T, the IBBS200D or IBBS200T must be configured with at least two battery packs consisting of 92 Ah storage batteries to avoid overcurrent of a single battery pack during the discharging.

Principles for stacking and combining cabinets Issue 01 (2014-04-30)


18


2 Overview

l

An IBBS200D or IBBS200T can be stacked only with an IBBS200D, IBBS200T, or TMC11H. When the IBBS200D or IBBS200T is stacked with the TMC11H, the TMC11H is stacked on the IBBS200D or IBBS200T.

l

An RFC can be stacked only below the APM30H or TMC11H.

l

If auxiliary cabinets, such as the battery cabinet IBBS200D/IBBS200T or transmission cabinet TMC11H, are required during an initial site construction, the auxiliary cabinets are positioned on the left side of basic cabinets. If both the battery cabinet and transmission cabinet are required, the battery cabinet is positioned on the left side of the basic cabinet, and the transmission cabinet is stacked on the battery cabinet or positioned on the left side of the battery cabinet.

l

During an initial site construction, space must be reserved for capacity expansion. Unless otherwise stated, the original cabinets remain in the original positions and new cabinets are added to the right side of original cabinets during capacity expansion. In a special scenario, new cabinets can be added to the left side of original cabinets.

l

A cabinet combination of one APM30H and one RFC is configured with one BBU by default. This cabinet combination can be configured with a maximum of two BBUs, and the power consumption of all BBU boards cannot exceed 1000 W. This principle applies to a new or expansion scenario.

Cabinet Configurations of a Single- or Dual-Mode BTS3900A A single- or dual-mode base station is configured with only one BBU, which is installed in the APM30H or TMC11H. When seven to twelve RFUs are configured, two RFCs are required. When a site is supplied with 110 or 220 V AC power and does not require backup power, the cabinet configurations of a single- or dual-mode base station with different requirements of space for customer equipment and carrier configurations are shown in the following figure.

2.3 BTS3900A (Ver.D) Configured with RFUs and RRUs When RFUs and RRUs are configured, a BTS3900A supports different cabinet configurations in 110 V AC, 220 V AC, or -48 V DC power supply scenarios.

Cabinet Configuration Principles l

A single BTS3900A can be configured with a maximum of six RFUs and nine RRUs. Therefore, deploy more than one site if the RFUs and RRUs to be configured exceed the maximum configuration.

l

When a BTS3900A is configured with RFUs and RRUs, the maximum configuration of RRUs is six RRUs of 2x60 W and three RRUs of 2x40 W.

Cabinet Configurations of a Single- or Dual-Mode BTS3900A A single- or dual-mode base station is configured with only one BBU, which is installed in the APM30H or TMC11H. When a site is supplied with 110 or 220 V AC power and does not require backup power, the cabinet configurations of a single- or dual-mode base station with different requirements of space for customer equipment and carrier configurations are shown in the following figure.

2.4 Installation Clearance Requirements The installation of the BTS3900A is classified into three scenarios: a single cabinet is installed alone, two cabinets are installed side by side, and two cabinets are stacked. When two cabinets are installed side by side, the clearance between them must range from 40 mm (1.57 in.) to 150 mm (5.91 in.). If a noise reduction module (NRM) is required, the minimum clearance between two cabinets is 300 mm (11.81 in.). The following figure shows the clearance requirements for the APM30H, TMC11H, RFC, and IBBS200D/IBBS200T configured at a BTS3900A site. NOTE

The three cabinets in the following figure may be an RFC, a TMC11H, and an IBBS200D. The installation clearances for an IBBS200T are the same as the installation clearances shown in the preceding figure, but its planform is different from any of the three cabinets in the preceding figure.
