Installation Guidelines

1. Junction Box Installation:

A. Position the junction box’s mounting bracket against the pole. Insert the two stainless

steel clamps into the bracket’s

B. Fasten the stainless steel clamp’s screws, securing the junction box onto the pole.

2. Connecting the Hybrid Trunk Cable (RRU Side) to Junction Box:

A. Open the unit’s cover by undoing the latches.

B. Unscrew and lift open the MTP® cassette.

C. Unscrew the hybrid cable port’s sealing nut, then, once free from the thread, slide it

over the hybrid trunk cable.




D. Lift open the hybrid trunk cable clamp; insert the hybrid trunk cable into the hybrid

cable port, push the cable in the box until the tip of the heat-shrink tube reaches the

printed mark. (see photo.)

E. Close the clamp and tighten screw using a flat-head screwdriver.

F. Screw the hybrid cable unit port’s sealing nut back on, tighten using a spanner.

3. Connecting the DC Power Cables to the Junction Box:

A. Route the cables (DC power cables and Optical cables) neatly clockwise around the

unit using the restraint hooks

B. Observe terminal assignments on the junction box’s back panel: Red cables to

unshaded <+>IN and Blue cables to shaded <+>IN. (see photo.)

C. Lift off the transparent terminal protective covers. Insert connectors by matching the

printed numbers on the cables with the corresponding terminals.

D. Secure connections by tightening each screw using a Phillips screwdriver, and press

the transparent protective terminal covers back over the terminals.

4. Connecting the Optical Cables to the Junction Box’s MTP® Cassette:




A. Close the MTP® cassette, tighten the screw to secure in place.

B. Carefully remove MTP® fibre connector’s dust caps.

C. Observe the fibre connector’s keyway (keyway must be on top, see photo). Make

sure the orientation is correct before attempting connection.

D. Connect MTP® fibre cables to assigned ports by matching the printed letters (A & B)

on the cables with the corresponding cassette ports. Push connectors in until they

click into place

E. Do a final check making sure there is no loose connection, and that no foreign

objects are left in the unit before closing the cover. Close the unit’s cover and tightly

fasten the latches.

5. Feeding of the 1 ¼” Hybrid Trunk Cable END 2 into the BBU room:




A. Unroll the excess hybrid trunk cable END 2 off the drum.

B. Feed through the hybrid trunk cable END 2 into the hut’s cable entry, all the way into

the BBU room.

6. Connecting the DC power cable (Detail A) to the RRU:

A. Open the RRU’s MPO cassette to access the DC power terminals.

B. Unscrew the RRU’s Jumper port gland’s sealing nut (Start with port gland labelled

“RRU1” for the first installation), Once free off the thread, slide the sealing nut over

the Hybrid jumper cable.

C. Insert the Hybrid jumper cable (END 1, Detail A) into the RRU1 port gland, all the

way in until the Hybrid jumper, cable’s heat shrink tube reaches the tip of the port

gland.

D. Tighten the port gland’s nut to secure the connection.




E. Lift open the RRU’s MPO cassette to access the DC terminal blocks. Route the DC

power cables neatly anti- clockwise around the unit using the attached restraint

hooks. Lift off the transparent protective terminal cover

F. Connect the DC power cables, observing the terminal assignments on the Junction

box’s back panel: Red cable to RRU1 in the unshaded <+>OUT and Blue cable to

RRU1 in the shaded <+>OUT. (see photo.) Repeat installation process in

chronological arrangement for every succeeding Hybrid jumper cable.

G. Secure connections by tightening each screw using a Phillips screwdriver, and press

the transparent protective terminal covers back over the terminals.

7. Connecting the Optical cable (Detail A) to the RRU:

A. Close the RRU’s MPO Cassette after connecting the DC power cables. Route the

optical cables anti-clockwise around the unit using the cable saddles, making a loop

from the connection point through the other side of the MPO cassette. (See Photo.)

B. Carefully remove dust caps. Observe matching terminal and cable numberings

before attempting connection, cassette terminal block starting with “RRU1” for the

first installation.

C. Connect the LC connectors by pushing each pair into the cassette’s terminal until

the connectors make an audible click.




D. Follow the same procedures for every succeeding Hybrid jumper installation

E. Recheck all connections of power and optical cables in terms of labels and

numbering. Arrange cables neatly in the unit.

F. Do a final check making sure there is no loose connection, and that no foreign

objects are left in the unit before, closing the cover. Close the unit’s cover and tightly

fasten the latches.

8. Connecting the Hybrid jumper tail (Detail B) to the RRU:

A. Open the unit’s connection port by unscrewing the cover using a Philipps

screwdriver.

B. Remove the rubber port sealing tabs and unscrew the unit’s clamp using a Philipps

screwdriver. Observe port labels for cable assignments. (See photo.)

C. Carefully remove LC connector’s dust caps.




D. Push the connectors all the way in until it makes an audible click, confirming

connection. Do not confuse cable-to-port labels.

E. Tighten the unit’s clamp to secure connection. Close the unit’s cover and securely

tighten the screws for effective water sealing.

F. For the DC power installation, refer to the diagram printed at the back panel of the

unit’s cover
