Huawei BBU5900 Introduction

Hello everyone！   In this post, I will introduce the BBU5900 in detail to facilitate your understanding of the product.   BBU5900 exterior   Figure 1 BBU5900 exterior   BBU Working Principle   A BBU consists of the following subsystems: baseband subsystem, power and mechanical subsystem, transmission subsystem, interconnection subsystem, main control subsystem, monitoring subsystem, and clock subsystem. Each subsystem consists of different modules, as listed in the following table.   Table 1 Components of the BBU Subsystem Module Baseband subsystem Baseband processing unit (BBP) Power and mechanical subsystem Backplane, fan unit (FAN), and power and environment interface unit (PEU) Transmission subsystem Main processing and transmission unit (MPT) Interconnection subsystem MPT Main control subsystem MPT Monitoring subsystem PEU and environment interface unit (EIU) Clock subsystem MPT and satellite card and clock unit (SCU)   The following figure shows the working principle of a BBU. Figure 2 Working principle of a BBU   BBU Function A BBU performs the following functions: Provides ports for connecting to the transmission equipment, RF modules, USB devices, external reference clock, and LMT or MAE to transmit signals, perform automatic base station software upgrade, receive reference clock signals, and support BBU maintenance on the LMT or MAE. Manages the entire base station system. The management involves uplink and downlink data processing, signaling processing, resource management, and operation and maintenance.   BBU5900 Matching Boards   Table 2 lists the boards that can be used in the BBU5900. Matching Boards Main control board UMPTb1, UMPTb2, UMPTb3, UMPTb9, UMPTe1, UMPTe2, UMPTe3, UMPTg1, UMPTg2, UMPTg3, UMPTga1, UMPTga2, UMPTga3 Baseband processing board UBBPd1, UBBPd2, UBBPd3, UBBPd4, UBBPd5, UBBPd6, UBBPd9, UBBPe1, UBBPe2, UBBPe3, UBBPe4, UBBPe5, UBBPe6, UBBPe18, UBBPg1, UBBPg1a, UBBPg2, UBBPg2a, UBBPg3b, UBBPg3, UBBPg4, UBBPei, UBBPem, UBBPex2, UBBPf1, UBBPf3, UBBPfw1 Satellite-card board USCUb18, USCUb16, USCUb14, USCUb11 Fan module FANf Power module UPEUe Environment monitoring unit UEIUb   BBU5900 Equipment specifications   Table 3 BBU5900 Equipment specifications Equipment specifications Power input type –48 V DC Operating voltage –38.4 V DC to –57 V DC Dimensions (H x W x D) 86 mm x 442 mm x 310 mm (3.39 in. x 17.40 in. x 12.20 in.)

Therefore, capacity specifications are not described in this section. The difference between the BBU3900 and the BBU3910 is that the BBU3910 supports more boards, because the BBU3910 is released later than the BBU3900.   That's all, welcome to read!
