Compared with the BBU3900, the BBU3910 has enhanced backplane switching capabilities: In the BBU3900, no direct route is available between slots 0, 1, 4, and 5, and data between them must be transferred by slot 2 or 3. In the BBU3910, however, data can be directly exchanged between slots 0 through 5.
BBU3910 is almost twice that in the BBU3900. 1.2 Exterior of the BBU3900&BBU3910 The BBU3900&BBU3910 is a case measuring 19 inch wide and 2 U high. It can be installed indoors, such as an office building or residence, or be installed in a cabinet with surge protection in an outdoor place, such as a basement, balcony, corridor, or garage.
Connec Quantit Description UBBPd/ CPRI0 Data transmission ports that interconnect UBBPe female the BBU3900&BBU3910 and the RF CPRI5 modules. These ports support electrical and optical signal input and output. UBBPem CPRI0 QSFP They are data transmission ports connecting a BBU to an RMU3900A, and support CPRI1 input and output of optical signals.
Connects to an external FE/GE1 transmission device 1.3.9 UPEU The UPEU is short for universal power and environment interface unit. The BBU3900 supports UPEUa and UPEUc. The BBU3910 supports only the UPEUd. Panel Figure 1-19 shows the panel of the UPEUa.
MON1 RJ45 Receives RS485 signal input 1 1.3.11 FAN There are two fan unit types for the BBU3900: FAN and FANc. And the FANd is a fan unit for the BBU3910.. Panel Figure 1-23 shows the panel of the FAN.
1 Overview Figure 1-26 FANe panel Functions The FAN dissipates heat from the BBU3900&BBU3910. It monitors the inlet temperature, controls the rotation speed of the fans, and reports the status of the fans to the LMPT or UMPT in the BBU3900&BBU3910.
Functions as a secondary interconnection port and connects to a primary interconnection port. Has four 10GE TX/RX channels. 1.4 BBU3900&BBU3910 Board Configuration Figure 1-28 shows the typical configuration of the BBU3900&BBU3910.
