Ensemble Communications Inc.5-2Operator’s Guide to the Fiberless SystemUnpacking and Inventory•Unpack the base station chassis and its components on a flat, clean surface at the installation site. WARNINGKeep all interface cards in their antistatic bags in the shipping box until you are ready to install them.•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. •Inspect all components to determine that they are not dam-aged. If a component appears to be damaged or is missing, con-tact your shipper and Ensemble Customer Service immediately.•Save all packing materials.System Components •Fiberless 16-slot base station chassis (CH16000)•Fan tray assembly•1 or 2 Control Interface Cards (CIC1000)•1 or 2 Network Interface Cards (NIC1440)•1 or more Modem Interface Cards (MIC1025)•Blank card panels to fill empty slots•19-inch (48-cm) and 23-inch (58-cm) rack mount bracketsNote Interface cards are shipped in separate boxes and must be installed on site.Note Ensemble does not provide power supplies. See page 10 for recommended power source information.
Ensemble Communications Inc.Installing the Base Station Indoor Equipment5-3Chassis 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, sep-arated 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.Power and Grounding SystemThe base station chassis is normally shipped with the A bus ground stud internally connected to chassis ground and the B bus ground stud internally connected to digital ground. A removable metal jumper bridges chassis and digital ground is on the backplane. CautionIf you have already seated the interface cards, unseat all of them before making power connections.CautionMake sure all circuit breakers are off prior to making any con-nections.The following describes the connection procedure. Figure 5-1 shows the power connectors in the power terminal block.Figure 5-1. Base Station Power Connections (Chassis Rear View)
Ensemble Communications Inc.5-4Operator’s Guide to the Fiberless SystemPower ConnectionProcedureNote 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. Remove the plastic protective covering from the power termi-nal blocks.2. Connect the -48 VDC conductors for each of the buses (A and B) to separate dedicated 50-amp circuit breakers. 3. Connect the return conductors to the appropriate return buses on the PDF. 4. After all power connections have been made and with all inter-face cards unseated in the chassis, turn on the circuit breakers. 5. Using a digital voltmeter (DVM), verify that proper polarity and voltage are present on both buses at the base station power block.6. Install fan tray and verify that fans are on.7. After all connections have been verified, return the circuit breakers to the off position.8. Install the provided plastic protective cover over the power and ground terminal block..

Failure to exercise ESD precautions can damage the interface cards.CautionBefore initially inserting interface cards, ensure the circuit breakers supplying both the A and B power buses are turned off.CautionPopulate any empty slots with the supplied blank cards so air-flow is properly directed among the cards. Install cards in slots as listed in Table 5-1. Slots and cards are keyed to prevent installing them in the wrong slot.1. Position and slide the interface card into the slot until it is seated (See Figure 5-2).Figure 5-2. Base Station Card Positioning2. Press down on the card lever until it snaps shut. 3. Then tighten the screws at the top and bottom of the card4. Repeat this process for each interface card to be installed.Note When seated, a mechanical latch locks the interface cards lock into place.

Verify that Status LED on each card illuminates and begins flashing yellow.Figure 5-3 shows the cards in their appropriate slots.Figure 5-3.

Ensemble Communications Inc.5-8Operator’s Guide to the Fiberless SystemControl I/O CardThe 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.Table 5-2: Control I/O Panel ComponentsName Identifier FunctionSLOT1 CNSL ASLOT2 CNSL BExternal management and controlExternal I/O control Ext I/O CTRL External diagnostic equipmentBITS clock reference port BITS Clock input from the Building Inte-grated Timing Supply (BITS)Primary FMS portSecondary FMS portFMS A - SLOT 1FMS B - SLOT 2Interface with FMS and central officeCraft port ACraft port BCRAFT A - SLOT 1CRAFT B - SLOT 2Interface of out-of-band network management and for development, maintenance, testing, and configura-tionDS-3 NIC A Tx/Rx portsDS-3 NIC B Tx/Rx portsSLOT 8 Tx/RxSLOT 9 Tx/RxInterface with central office, network, and FMSChassis bus extender OUTChassis bus extender INSHELF-TO-SHELFCOMM DIGITAL —TX/RXInterconnection for extension chassisGPS input port GPS RX — 10 MHzGPS RX PPSGPS transceiver 10 MHz inputGPS transceiver PPS inputTable 5-3: Control I/O PortsNumber of Ports Type Function2 DB9 female RS-232 Console access to the CICs2 RJ-45 jack 10BaseT FEMS access2 RJ-45 jack 10BaseT Local craft access1 DB9 male BITS Building Integrated Timing Source (BITS) input1 DB9 male serial External I/O control4 BNC timing Intershelf synchronization2 RJ11 jack serial Intershelf data communication2 BNC GPS GPS timing input (PPS and 10 MHz)
