5-2 Operator’s Guide to the Fiberless System Unpacking and Inventory • Unpack the base station chassis and its components on a flat, clean surface at the installation site. WARNING Keep all interface cards in their antistatic bags in the shipping box until you are ready to install them. System Components Ensemble Communications Inc. • Check the quantity of items received against the packing list and a copy of the purchase order to ensure that you have received your complete order.
Installing the Base Station Indoor Equipment 5-3 Chassis Installation • Mount the bottom of the first base station chassis assembly approximately 5.25 inches (13.3 cm) above the bottom of the rack or cabinet. • Install additional base station chassis, one above the other, separated by a single RU (1.75 inch/4.4 cm) blank panel between them. • Secure the base station chassis and blank panels with the machine screws provided by the rack or cabinet manufacturer.
5-4 Operator’s Guide to the Fiberless System Power Connection Procedure Note For power runs up to 50 feet, use #8 gauge (AWG) wire. For longer runs, select the proper wire size to avoid excessive voltage drop. Make connections to the base station using crimp type lugs. Use the provided #10 screw to route the -48 VDC power and return conductors to the Power Distribution Frame (PDF) on the power and ground barrier strip for each conductor. 1.
Installing the Base Station Indoor Equipment 5-5 Interface Card Installation WARNING Wear a grounded wrist strap when handling the interface cards. Failure to exercise ESD precautions can damage the interface cards. Caution Before initially inserting interface cards, ensure the circuit breakers supplying both the A and B power buses are turned off. Caution Populate any empty slots with the supplied blank cards so airflow is properly directed among the cards.
5-6 Operator’s Guide to the Fiberless System 5. Turn on chassis A and B bus circuit breakers. 6. Verify that the fan tray LED is green and that fans are on. 7. Verify that Status LED on each card illuminates and begins flashing yellow. Table 5-1: Interface Card Slots Slot Interface Card 1 and 2 CIC 1000 (Control Interface Card) 8 and 9 NIC1340 (DS-3 Network Interface Card) 3-7 and 10-14 MIC1025 (single Modem Interface Card) Figure 5-3 shows the cards in their appropriate slots.
Installing the Base Station Indoor Equipment 5-7 IF Cable Connectors Following the system design plan, connect the cables from each ODU to a specific base station chassis ODU connector. • Connect IF cables to MIC IF ports. • Connect IF cables for redundant ODUs to IF RIC ports. Figure 5-4 shows the connectors on the back of the base station. Control I/O Panel MIC IF Connector Panel (MICs to ODUs) IF RIC Backhaul (DS-3) RIC Power Buses Figure 5-4.
5-8 Operator’s Guide to the Fiberless System Control I/O Card The control I/O card provides local management connectivity for network management, building integrated timing supply (BITS), global positioning system (GPS), and intershelf interfaces. It is installed in a vertical slot along the right edge of the rear of the chassis. The control I/O panel components are listed in Table 5-2, and the I/O ports are listed in Table 5-3.
Installing the Base Station Indoor Equipment 5-9 Backhaul Connection • Connect a 75 Ohm BNC RG-59 cable from the appropriate transmit port (Tx) to the router’s DS-3 receive port. • Connect another RG-59 cable from the appropriate base station receiver port (Rx) to the router’s DS-3 transmit port.
