The day-contact input and output cable uses a balanced twisted-pair cable, connecting the ZXSDR BS8900A and the external monitoring system. This cable inputs dry-contact signals from external devices or outputs dry-contact signals of this device. If the ZXSDR BS8900A is connected to external monitoring devices through dry-contact cables, an LPU subrack must be installed. The external dry-contact signals must go through the LPU first, and then to the BBU. Furthermore, RS232 and RS485 monitoring cables are also connected to the LPU. The external dry-contact signals, RS232 monitoring signals, and RS485 monitoring signals are transmitted to the BBU through the LPU and the SA cable between the LPU and BBU. Note: The RS232 cable and RS485 cable of the ZXSDR BS8900A are connected to the power subrack and fan subrack of the baseband cabinet. No RS232/RS485 interface is left for external devices. The SA monitoring cable between the LPU and BBU is installed before delivery. Prerequisite The ESD wrist strap must be worn. Relevant monitoring equipment is installed. Context If the ZXSDR BS8900A does not need dry-contact/FE lightning protection, that is; external dry-contact cables are not connected and the S1 interface is not an electrical interface, no LPU subrack is required. The RS232 and RS485 monitoring cables are directly connected to the corresponding interface of the SA board. For an overview of the SA monitoring cable, see Figure 7-38. 7-54 SJ-20150203110107-011|2016-03-23 (R1.1) ZTE Proprietary and Confidential Chapter 7 Cable Installation Figure 7-38 SA Monitoring Cable 1. End A is for connection to the SA board. 2. End B1 is for connection to an E1/T1 cable (this interface is not used for LTE) 3. End B2 is for connection to an RS232 cable. 4. End B3 is for connection to a dry-contact cable. 5. End B4 is for connection to the grounding point of the BBU. 6. End B5 is for connection to an RS485 cable. Steps 1. Paste labels in accordance with the terminals and wire sequence of the dry contact cable. 2. Route the dry contact cable from the external monitoring device to the right cable trough of the RC8910A cabinet through the base, thread the cable through the waterproof module at the right bottom of the BC8910A cabinet into the BC8910A cabinet, and then to the MON_IN/OUT_GO port of the LPU. For the routing of the external MON cable, see Figure 7-39. 7-55 SJ-20150203110107-011|2016-03-23 (R1.1) ZTE Proprietary and Confidential ZXSDR BS8900A Hardware Installation Figure 7-39 External MON Cable Routing 3.
