About This Document

This chapter lists the tools and instruments that must be obtained before the installation. It also specifies the skills that the onsite personnel must have. 4 Unpacking Check Unpack and check the delivered equipment to ensure that all the materials are included and intact. 5 Obtaining the ESN The electronic serial number (ESN) is a unique identifier of a NE. Record the ESN of the base station before the installation for future commissioning. 6 Installation Process Before the BTS3900 cabinets are delivered, boards inside the cabinets have been installed. You only need to install the cabinet and cables onsite. Some optional components may also need to be installed based on onsite requirements. 7 Checking Installed Modules and Cables Modules and cables in the cabinet have been installed before delivery. You need to check whether the modules and cables are installed securely. 8 Installing a Base A BTS3900 cabinet can be installed on a base. The base can be installed either on a concrete floor or ESD floor according to the equipment room conditions and customer's requirements. 9 Installing the Cabinet A BTS3900 cabinet can be installed alone, side by side with another BTS3900 cabinet, or stacked on another BTS3900 cabinet. This section describes the procedure for installing the BTS3900 (Ver.D) cabinets in the preceding modes. The procedures for installing the BTS3900(Ver.B), BTS3900(Ver.C), and BTS3900(Ver.D) cabinets are the same. 10 Installing a PGND Cable and an Equipotential Cable A PGND cable connects a PGND screw in a cabinet and a PGND bar to ensure proper grounding of the cabinet. An equipotential cable connects PGND screws on different cabinets to ensure the equipotential bonding between the cabinets. 11 Installing Optional Modules and Their Cables This chapter describes procedures for installing the optional modules and their cables onsite. 12 Installing Cables Before cabinets are delivered, the boards and cables inside the cabinets have been installed. You must install the external cables and cables for optional components onsite. 13 Installation Checklist After the cabinets and devices are installed, you need to check the installation items, installation environment, and cable-related items. 14 Powering On a Base Station This section describes how to power on a base station and handle a failure in the power supply to the components in a cabinet.
