Subracks are numbered from bottom to top. BSC6910 GSM Hardware Description 3 Cabinet Item Specifications (N68E-22) Specifications (N68E-21-N) range Power The maximum power consumption of a subrack is 4000 W. consumption Currently, the cabinet power consumption is rated at 7100 W through hardware and software configurations, preventing the high density of power from affecting heat dissipation. It is recommended that the power distribution system provide a maximum of 4000 W power per subrack and 7100 W power per cabinet to facilitate capacity expansion. Heat consumption It is recommended that the air conditioning system dissipate a maximum of 4000 W heat per subrack and 7100 W heat per cabinet to facilitate capacity expansion. Heat dissipation Fans, air deflectors, and an air defense frame are installed in a BSC cabinet. Each subrack has separate air channels where air flows in from the front and flows out from the rear, ensuring good heat dissipation. An empty cabinet is configured with front and rear doors, side panels, and a set of cables. When the voltage of power supply is lower than the lower threshold for the input voltage, multiple boards may become abnormal at the same time. Therefore, check the power system if multiple boards become abnormal at the same time. 3.4 Cabinet Cable Cabinet cables consists of cabinet power cables, PGND cables, and cabinet signal cables. 3.4.1 Relationship Between the PDF and Subracks This section describes the relationship between the power outputs on the Power Distribution Frame (PDF) and the inputs of the subracks configured in a cabinet. The power outputs on the PDF connect to the power inputs on each subrack of the BSC6910. In each subrack, there are two power entry modules (PEMs). On each PEM, there are two power inputs. As shown in Figure 3-3 and Figure 3-4, PDF output area A consists of PDF outputs 1 and 2, and PDF output area B consists of PDF outputs 3 and 4.PDF output areas A and B work in active/standby mode. The BSC6910 power supply principles are as follows: Issue 08 (2014-09-12) Huawei Proprietary and Confidential 11 Copyright © Huawei Technologies Co., Ltd. BSC6910 GSM Hardware Description 3 Cabinet The PDF provides two power sources (one active and one standby) for the equipment and one PGND connection for each cabinet. PEM 00 and PEM 01 work in active/standby mode and connect to the active and standby power sources, respectively. PEM 00 and PEM 01 work concurrently in normal cases. If either of them becomes faulty, the other PEM continues to supply power to the system to ensure stable operation. Therefore, you can rectify one faulty power input when the power is properly supplied, improving the reliability and availability of the power supply system. The two power outputs of PEM 00 work in load sharing mode. The subrack that houses PEM 00 can work properly only when the two power outputs of PEM 00 are normal. The working principle of PEM 01 is the same as that of PEM 00. Figure 3-3 shows the relationship between power outputs and inputs when only one subrack is configured in a cabinet. Figure 3-3 Relationship between power outputs and inputs when only one subrack is configured Figure 3-4 shows the relationship between power outputs and inputs when three subracks are configured in a cabinet.
