Installation Manual

R20 1X UBS Macro B T S Hardw are Installation Full installation sequence
5. Mount the UBS Macro BTS carrier strip assembly to the rack at the predetermined height.
First, measure and install 2 hanger screws in the rack rails; one screw on each left and
right side at the proper height. Second, four people lift the UBS Macro BTS carrier strip
assembly via the carrier strip handles and hang the assembly on the 2 hanger screws in
the rack rails. Install 2 screws in the keyholes at the bottom of each carrier strip. Third,
completely fasten the UBS assembly/carrier strips using 22 more screws; 11 screws on
each left and right side. Completely tighten these 22 crews. Then completely tighten the 4
screws in the keyholes.
6. ** Install the additional equipment required to expand the UBS Macro BTS low -capacity
starter/expansion frame to the mid -capacity frame configuration. If the initial UBS Macro
BTS installation is for a low -capacity frame configuration, skip this task and go to T ask
7. P erform this task only if the initial UBS Macro BTS installation is for a mid -capacity
frame configuration.
7. ** F or -48 V DC or 220 V AC UBS only , connect the +27 V DC power output cable from
the rear of the PSM shelf to the +27 V DC power input cable on the rear of the PDU .
Connect the 50 -conductor cable (supplied with PSM shelf) between the PSM shelf front
panel ALARM/CONTROL connector and S SI PSM connector .
8. Route the customer supplied TX/RX main and RX diversity antenna cables to the front of
the Integrated Duplexer RX Filters (IDRFs) at the top of the frame. Connect each antenna
cable to the corresponding IDRF connector .
9. Connect customer supplied 0.25 W , 50 -Ohm, SMA -type terminators to unused directional
coupler port connectors on the front of the IDRFs.
10. ** Install optional RGPS cable (AA). Connect the 15 -pin D -connector to the RGPS connector
on the front of the S SI. Route the loose end of the cable to the RGPS lightning arrester and
connect the wires there. Skip this task if the optional RGPS head is not required.
11. ** Install T1/E1 balanced span I/O cable (W). Connect the 37 -pin D -connector to the SP AN
connector on the front of the S SI. Route the loose end of the cable to the site span line
interconnect equipment and connect the wires.
12. ** Install E1 unbalanced span I/O coaxial cables (customer supplied). Route 75 -Ohm
coaxial cables, with BNC connectors, from the site span line interconnect equipment to the
S SI. Connect each cable to the corresponding BNC connector on the S SI E1 daughter card.
13. ** Install Customer Alarm Input/Output (IP/OP) cables (X). Connect the 37 -pin D -connector
to the corresponding CUSTOMER IP 1 -12 OP 1 -4 connector and CUSTOMER IP 13 -24 OP
5 -8 connector on the front of the S SI. Route the loose end of the cables to the customer
IP/OP interconnect equipment and connect the wires.
14. ** Ensure that all circuit breakers are open on the PDU . F or +27 V DC UBS only: attach an
Orange 2 -contact DC connector to Red and Black wires. Connect this Orange connector
to the +27 V DC input power cable on the rear of the PDU . Route the loose ends of the
wires to the site +27 V DC source and connect the wires.
15. ** Ensure that all circuit breakers are open on the PDU . F or -48 V DC UBS only: attach a
Blue 2 -contact DC connector to Blue and Black wires. Connect this Blue connector to the
Blue DC INP UT connector on the rear of the -48 V DC PSM shelf . Route the loose ends of
the wires to the site -48 V DC source and connect the wires.
16. ** Ensure that all circuit breakers are open on the PDU . F or 220 V AC UBS only: attach
customer supplied wiring and conduit for 220 V AC lines. Connect wires and required
insertion bridges to the AC INP UT terminal block on the rear of the AC PSM shelf . Route
the loose ends of the wires to the site 220 V AC source and connect the wires.
