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.
•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 brackets
Note 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.

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, 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 System
The 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.
Caution
If you have already seated the interface cards, unseat all of
them before making power connections.
Caution
Make 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.

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. 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.

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 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 Positioning
2. Press down on the card lever until it snaps shut.
3. Then tighten the screws at the top and bottom of the card
4. Repeat this process for each interface card to be installed.
Note When seated, a mechanical latch locks the interface cards lock into
place.

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.
Figure 5-3 shows the cards in their appropriate slots.

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 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.
