BTS3900A cabinet installation& fixation

APM30

over the RFC cabinet, should be fixed and tightened by 4 bolts





RFC cabinet fixed on the basement, four bolts should be tightened well

Base is fixed using 4 bolts on concrete foundation GF sites or metal grillage for RF sites

Leave 80 cm from the base frame to the end of the concrete foundation is desirable ( if available )

BTS cabinet base frame fixed on the basement, four bolts should be tightened well


BTS base frame must be leveled

Cabinet labeling system

Rectifier

AC power cables connected in PDP should be labeled, terminated and fixed

Labels

for all power cables inside the rectifier, all cables should be terminated


All Signal, Power and Ground cables inside the cabinet should have label

Antennas and RRU installation

- Stainless steel bolts, double nuts - Double nuts needed for Antenna fixation - Use the old antenna grounding cable for the new antenna after swap

- Stainless steel bolts, Spring washer and nut.


If there is available space on the Tower , the 2 RRU should be of different types ( 3G & 4G ) for each sector .. 4G on the left and 3G on the right

If there is no available space to install 2 RRU for each sector , we can install 3 RRU’s together but they should be of the same type 3G or 4G Page 17

Antenna Mechanical Tilt The HW Tri-band antenna length is 2.6 meters, should set mechanical tilt according to the marker of L=2.6

This small triangle using to define mechanical down tilt

Record and call OMC to confirm the M-tilt value of all the sectors HUAWEI CO., LTD. HISILICONTECHNOLOGIES SEMICONDUCTOR

RRU power cable grounding

From BTS When RRU power cable through into BTS cabinet, must use 6 in 1 grounding clamp for shield layer grounding of RRU power cable !

From RRU side The shielding layer of RRU power cable need to grounding using clip in RRU


6 in 1 grounding clamp, 1clamp can fix 6pcs RRU power cable.

Page 21

Antennas and RRU ports sealing

Wrap

3 layers of waterproof tape


Wrap

3 layers of insulation 3M tape

Top

and bottom black ties

Page 22

Use out door labels for upper jumpers ( fixed with black cable ties)

-

Use out door labels for Fiber, Power and ground cables

Use the Antenna port cover for the unused ports. Upper jumpers connectors should be sealed as mentioned before Using joint bar connect each RRU

Feeders installation

Wrap 3

layers of waterproof tape


Wrap 3

layers of insulation 3M tape

Top and

bottom black tie wraps

Page 24

Cable tray Sharp Edges should be covered by rubber

Subcontractor must make the VSWR for all the RF system before the swap and provide Snap shots inside the As built document

Outdoor Labels should be installed before and after the connectors Earth Reading should be taken before and after the Swap , reading should be less than 5 ohms

Feeders and fiber and power cables arranged inside the cable try in the mentioned order and all cables should be flat over the cable tray

Old cable should be shifted Without affecting their service


Feeder Grounding Kits to be installed and connected to the nearest grounding bar Feeder Grounding Kits to be isolated in the same way as the antenna connecter

After swap , the cable tray covers must be Fixed by Steal ties
