Macro Base Station Installation Procedures (NPM-2500) General Site Requirements Each site has unique requirements and characteristics. Consult your SOMA Networks technical representative for information about specific site requirements. See the Network Deployment Planning Guide for a comprehensive description of generic site requirements. Restricted Access The base station is intended for installation in restricted access locations only.
Chapter 2: Site Preparation Antenna Mounting Locations The base station uses two antennas (main and diversity) per sector. Consult your SOMA Networks technical representative for information about the size, weight, and installation requirements of the antennas. Cabling Requirements Ensure that your site has the necessary cable racking to accommodate the base station and that your site has external cable access ports for RF antenna cabling.

Chapter 3 PRE-I NSTALLATION REQUIREMENTS AND PROCEDURES Chapter 3 This chapter lists the tools and equipment required for installing and testing the base station. It also provides procedures for unpacking the racks and configuring individual cards and shelves. Contents Antistatic Precautions ................................................................................................................................... 20 Equipment, Tools, and Supplies Checklists .......................................
Macro Base Station Installation Procedures (NPM-2500) Antistatic Precautions W A R N I N G : Components in the base station are highly sensitive to electrostatic discharges (ESD). Follow the procedures described below to prevent unseen damage from occurring. To prevent damage to components from static electricity: Do not handle circuit boards unless you are using the appropriate antistatic protection, such as wrist straps, boot straps, boots, or a conductive mat.
Chapter 3: Pre-Installation Requirements and Procedures Equipment, Tools, and Supplies Checklists Tools The following tools are recommended for a typical base station installation: Allen key set Platform stepladder (6-foot) (optional) Cable ties Scissors Electrical tape Socket sets (Imperial and metric) Extension cord (optional) Tape measures (linen and metal) Heat gun (with heat shrink roll) (optional) Thomas and Betts (T&B) crimper Label maker Torque wrenche
Macro Base Station Installation Procedures (NPM-2500) N O T E : Ensure that your test equipment is correctly calibrated according to the methods and schedule specified by the manufacturer. The calibration date should be indicated on each piece of test equipment. Software Table 3.2 shows the software recommended to be installed on your laptop or workstation.
Chapter 3: Pre-Installation Requirements and Procedures Unpack and Inspect the Equipment Once you received your base station equipment, use the following procedure to ensure you have all the necessary parts. To unpack and inspect the base station equipment 1 Transport the shipping boxes to the installation area using a dolly or pallet jack. 2 Inspect the exterior packaging for any noticeable damage that may have occurred during shipment. 3 Unpack the equipment.

Chapter 4 INSTALLATION PROCEDURES Chapter 4 This chapter provides procedures on installing the NPM-2500. Contents Attach the Base Station Components ........................................................................................................... Install the Radio Modules .............................................................................................................................. Connect the Power Supply ..........................................................................
Macro Base Station Installation Procedures (NPM-2500) Attach the Base Station Components The following base station components are designed to be rack-mounted on a standard 19-inch telecommunications rack: NPM-2500 chassis Radio module shelf PDP The components typically use four M5 screws (two on each side) to attach to the rack. The recommended torque for each screw is 3 N•m (27 inch-pounds). The edge router for the site is typically installed on the same rack as the base station equipment.
Chapter 4: Installation Procedures Install the Radio Modules Two radio modules are used per sector, main and diversity. EXT/ LNA SER DES UAR T ANT F U S E EXT/LNA LO OUT LO IN POWER SUPPLY SERDES UART ANT Figure 4.1 Radio Module Insertion To install the radio modules 1 Remove the radio module from its protective bag. 2 Orient the radio module properly. 3 Slide the radio module into the first available radio module slot.
Macro Base Station Installation Procedures (NPM-2500) Connect the Power Supply Refer to the MOPs before scheduling or beginning any work involving the site’s main power. Before proceeding with this procedure, ensure that all the necessary site cable layout, runaway, and grid work has been completed. W A R N I N G : Ensure that the necessary requirements and procedures have been reviewed prior to the start of any power-related activity. Refer to your power cut-over MOP for procedures specific to your site.
Chapter 4: Installation Procedures Configure Jumpers on Sector Controller A Concurrent 310 card is used for the sector controller. It may be necessary to modify the jumper settings, as the base station uses a configuration of these cards that differs from the manufacturer’s original settings. N O T E : If the card is pre-installed in the chassis, then it has already been configured and this procedure is not required. Jumper Settings Table 4.
