3.4 Drilling
Warning:
Unauthorized drilling on the cabinet is strictly prohibited. Improper drilling may damage the
connections and cables inside the cabinet and the metal filings produced during the drilling may
cause short-circuits of the circuit boards if they fall into the cabinet.
Wear protective insulation gloves and remove the cables inside the cabinet
before drilling holes on the cabinet.
Take care of your eyes when drilling holes. As the splashing metal burrs
&scraps may hurt your eyes.
Prevent metal scraps from entering the cabinet inside.
Improper drilling will damage the electromagnetic shielding performance of
the cabinet.
Clean up the metal scraps after drilling.
3.5 Thunderstorms
Danger:
High-voltage and AC oper ations and operations on the steel towers and masts are strictly
prohibited in a stormy weather.
Thunderstorms
can
generate
powerful
electromagnetic
field
in
the
atmosphere. Therefore, equipment should be grounded properly in order to
prevent the equipment from being thunderstruck.
3.6 Static Electricity
Caution:
Static electricity generated by the human body may damage the electrostatic-sensitive parts on
the circuit boards, such as large-scale integrated circuit (IC).

Precautions
Safety Precautions
electrostatic charge carried by human body may go up to 30 kV, which will
remain on the human body for a rather long period of time. The operator’s
cont act with the sensitive component and the resultant electric discharge
will cause damage to the component.
Before contacting/touching any equipment such as holding plug-in boards,
circuit boards and IC chips, put on the anti -static wrist strap with one end
well grounded so as to prevent sensitive parts from getting damaged by
static electricity on the human body.
Before operators touch the board or module, they should release the
electrostatic charge in their body. That is, before the operator touches a
board or a module, he or she must wear the anti -static grounded wrist strap.
The connecting line between the wrist and the grounding point should
connect in series with a resistance greater than 1 M¦¸ to protect people
from being accidentally shocked. The resistance value greater than 1 M, is
rather low in terms of electrostatic voltage discharging. The anti-static wrist
strap should be checked regularly. Using other cable to replace the cable
of anti-static wrist strap is strictly prohibited.
Electrostatic -sensitive board or module should not be in contact with the
object with static electricity or the object that may easily generate static
electricity. For instance, packaging bags, delivery boxes and conveyor
belts made of insulating materials will generate st atic electricity by
themselves, and can cause electrostatic charging when in contact with
human body or the earth and might thus bring forth damages.
Electrostatic -sensitive
boards
or
modules
can
only
contact
quality
discharging materials, such as anti -static packing bags. The board in stock
or in the course of transportation should be packaged with anti -static
packing bag.
Before the measurement device is connected to boards or modules, first
discharge its static electricity, that is, the measurement device should be
grounded first.
The single board or module should not be placed near strong DC magnetic
field, for instance, near the cathode ray tube of the oscilloscope. The safety
distance should be at least 10 cm.
Damage caused by static electricity is acc umulative. If the damage is slight,
the component will not malfunction. However, as the number of damages
increase, the components may suddenly fail. The electrostatic discharging
damage to the component is of two types: obvious damage and hidden
damage. Hidden damage is not shown when the damage occurs, whereas
the component may become vulnerable and easily get damaged under the
condition of over- voltage and of high-temperature.
The correct way of wearing anti-static wrist strap is shown in Figure 1.

Caution:
Before connecting the cables, check the correctness of labels and then make the connection.
3.8 Leakage Current
Warning:
To avoid the occurrence of large leakage current, the equipment must be grounded before
connecting to the power supply.
Before connecting the AC input power supply, the operation and
maintenance personnel should first connect the protection-grounding
terminal of the equipment housing to the earth. The purpose of doing so is
to avoid electric shock on human body resulting from leakage current,
which is usually caused by the earth capacitance of the EMI wave filter at
the AC power supply input terminal of the equipment or the Y capacitance
of the primary power supply.

5.2 Definition of the Environment
The uppermost level limit of the environment that can be exposed to radio
magnetic radiation is of two kinds: one is "controlled environment" and the other
is "uncontrolled environment " with less radiation.
Controlled Environment
Controlled environment refers to a certain location where the personnel who
enter the area are aware of the potential threat of exposing themselves to the
radio frequency radiation environment. Generally, the personnel enter such
areas for the profession requirements and they get acquainted with this danger
or they just pass by the areas where possible radiation exists. The magnetic
field level of the area is higher than that of "uncontrolled environment" but no
greater than that of "controlled environment" listed in the table.
Uncontrolled Environment
"Uncontrolled environment" refers to a certain location where the personnel who
enter the area are not aware of the potential threat of exposing themselve s to
the radio frequency radiation environment, and they cannot control the
environment where they are situated. This location may include living
environment or working environment. The magnetic field level of the location
cannot
be
greater
than
the
upperm ost
level
under
the
"uncontrolled
environment" listed in the table.
5.3 Operation Codes
Warning:
When operating on the high intensity radio frequency signal equipment, bear in mind that the
high-intensity microwave is detrimental to human health.
6 Laser

III. Drilling
Drill holes on the floor at the marks of the cabinet connecting holes with a percussion
drill. The drill bit size should be v14 or v16.
Caution:
1. Generally, the selected drill bit is bigger than the expansion bolt. If the hole diameter is too small for
the F14 drill bit, enlarge the hole diameter by technical means.
2. Hold the drilling bit vertical to the floor during drilling. Hold tight the drillstock with two hands to keep it
in the right direction, as vibrations of the drill may damage the floor or produce a slanting hole.
3. The hole depth should be the length of the expansion bolt stem plus the drill bit. All holes should
share the same. Before measuring the hole depth, remove the dust inside the hole with a vacuum
cleaner, then drill again if necessary.
4. If the ground is too hard and smooth to settle the drill bit, punch out a pit with a chisel before drilling.
3.2.3 Installing Lower support
I. Installing the expansion bolt
1)
Before the installation, remove the dust inside and outside the holes with a
vacuum cleaner, and then check the hole distance. Whenever big errors occur,
the concerned hole must be re-located and re-drilled.
2)
Unfix the spring washer, nut and the big plain washer, put the bolt into the hole
and strike it with a hammer (such as nail hammer) until the bolt is completely
driven into the hole. To avoid the vibration of the bolt in the hole, put the nut on
the bolt and screw the nut until the bolt is slightly exploded in the hole.
Caution:
Take off the spring washer before installation, otherwise the washer will get invalid when the expansion
bolt is knocked. Carefully knock the bolt into the hole so as to avoid damaging the bolt thread.
II. Installing the lower support
1)
Place the insulating plate and the lower support in turn aligning with the four
expansion bolts.
2)

The heights of A600 series support assemblies I, II and, III can be adjusted steplessly
within their adjustable ranges. The heights are adjusted by moving the upper and
lower supports.
Type IV assembly is a height-fixed support. It is mainly suitable for ultra-high and
ultra-low floors. The minimum applicable floor height of this assembly is 140mm.
III. Support installation
The support is installed in the floor-bracketing mode. Namely, bracket the floor
between the cabinet and the support, then run the bolts through the anti-static floor to
fix the cabinet and the support. In this way, the cabinet can be firmly fixed and
supported.
IV. Number of supports
2N installation supports are used to install the cabinets, i. e., N cabinets should be
supported with 2N supports. Figure 3-9 is the schematic diagram of cabinet
installation on anti-static floor.

3.3.3 Locating Cabinet
I. Determine the cabinet location
The installation position of the cabinet should be determined based on the predefined
benchmark dimensions in project plane design. When doing this, try to avoid the
interference between the installation supports and the anti-static floor framework. Try
as much as possible to keep the intactness of the framework. If the interference is
unavoidable, remove the floor framework at the place where the interference occurs
during the installation. The first cabinet should be aligned with the floor edge.

II. Marking
Place the lower support of the cabinet on the ground as per the cabinet layout (make
sure it is in correct direction). Mark the positions for all connecting holes (each
cabinet has four connecting holes) of the cabinet on the floor.
III. Drilling
Remove the lower support and drill a hole through the marked place for each
connecting hole on the anti-static floor with a v20 drill bit.
3.3.4 Locating Support
I. Positioning and marking for support
Place the support below the anti-static floor. Align the connecting holes of the support
with the holes on the anti-static floor. Take the installation hole of the support as the
template. Mark positions for the expansion bolts on the concrete floor.
Caution:
The support should be installed strictly based on the blueprint shown in Figure 3-11. The connecting
holes at the outer side of the support should be aligned with the floor holes to prevent the support
extruding out of the cabinet.

II. Drilling
Use a Ö14 or Ö16 bit to drill holes at the marked places.
Caution:
1. Generally the size of the selected bit is bigger than the expansion bolt. If the hole diameter is too
small for the Ö14 drill bit, enlarge the hole diameter by technical means.
2. Hold the drilling bit vertical to the floor during drilling. Hold tight the drillstock with two hands to keep it
in the right direction, as vibrations of the drill may damage the floor and enlarge the size of the hole or
produce a slanting hole.
3. The hole depth should be the length of the expansion bolt stem plus the length of the drill bit. All bolts
should share the same depth. Before measuring the hole depth, remove the dust inside the hole with a
vacuum cleaner, and then drill again if necessary.
4. If the floor is too hard and smooth to settle the drill bit, punch a pit with a chisel to help positioning the
hole.
Marking and drilling are the fundamental steps for the hardware installation. If the
result is not accurate, it will bring trouble to the future work. Thus the quality at the
initial stage is the prerequisite of the whole project.
III. Installing expansion bolts
1)
Before fixing the expansion bolts, clean the dust inside and outside the hole with
a vacuum cleaner, then measure the distance between holes. For the hole with
intolerable error, it should be re-located and drilled again.
2)
Unfix the spring washers, nuts and plain washers; put the expansion bolts
perpendicularly into the installation holes; carefully knock the bolts with a
hammer (nail hammer) into the floor. To avoid the bolts getting loose in the hole,
install and tighten the nuts. Pull the expansion bolt until it slightly expands.
Caution:
Take off the spring washer before installation, otherwise the washer will get invalid when the expansion
bolt is knocked. Carefully knock the bolt into the hole so as to avoid damaging the bolt thread.
IV. Adjusting support height
Adjust the support to the predefined height, finely adjust the height -lock bolts on the
upper support to such an extent that they will not slip down by itself. Put the support

back to its installation position and run the expansion bolt through the installation hole
of the support.
3.3.5 Fixing Support
1)
Align the hole on the anti-static floor with the connecting holes of the support.
Screw the M12×70 bolts from the top to bottom. Meanwhile, place the plain
washer, spring washer and insulating covering (for the purpose of increasing the
contact area) as is shown in Figure 3-12.
2)
Gently knock the support to adjust the height so that the anti-static floor falls on
its original place on the framework. Make sure that the upper plane presses
against the anti-static floor. Then, screw the tightening bolts on the anti-static
floor.
3)
Make the expansion bolts cross fastened to 45Nm with a Torque wrench one by
one to reduce the stress between the bolts and the support.
4)
Tighten the height-lock bolts to 45Nm with a Torque wrench. The bolts in the
middle should be tightened first and then those on both sides. Figure 3-12 is the
diagram of bolt position.
Caution:
Fasten the three bolt sets in strict accordance with the above-mentioned procedures.

the support.
2)
Place the insulating plate, lower support on one by one, level the sections of the
subrack (both in landscape direction and longitudinal direction) with a level bar,
and see whether the level vial is in the middle. If the error is small, adjust the
levelness by striking the joint between the lower support and the support with a
rubber mallet while measuring; If the error is big, add washers between the lower
support and the insulating plate to adjust the levelness.
3)
When the levelness is adjusted, put the insulating covering, big plain washer,
spring washers 12 and bolts M12x70 into the four expansion bolts one by one.
Cross-fasten the nuts one by one; tighten the nuts to 45N& m so as to pull the
expansion bolts until they are fully expanded.
The installation process is shown in Figure 3-13.
Caution:
Install the insulating plate, insulating covering and the big plain washer as shown in Figure 3-13 to make
sure that the cabinet is insulated from earth.

3.4.2 Preparing U-bar Supports
When the allowable even load of the ground is lower than 5.5kN/m , and the cabinet
can not be installed against the wall, U-bar supports should be adopted to reduce the
load to the floor from the cabinet. The recommended material for the support is the
14b-3000 type of GB707-88 hot-rolled U-bar. The length is based on the actual
situation (The total length of the U-bar shown in the figure is 3000mm), Drill
installation holes for and fixing holes on the U-bar as shown in and Figure 3-18.
Remove all burrs and sharp edges; Finally paint the whole support with rustproof coat
and top-coat (The color of the coat should be the same with or similar to that of the
cabinet). Thus, the fabrication of U-bar support is completed.

The installation position of the cabinet should be determined based on the predefined
benchmark dimensions in project plane design.
II. Marking
Determine the installation positions of U-bar supports according to the installation
position of the cabinet. Mark several points with a tap and draw two straight
paralleling benchmark lines with a marker. The spacing between the two straight lines
is 630mm. Then determine the first hole position for the support U-bar on the two
lines according to the design requirement. Take this hole as the benchmark point to
mark the rest installation holes of the support one by one. Then re-measure the lines
to confirm the accuracy of each hole. The installation hole positions for U-bar
supports are shown in Figure 3-18.

III. Drilling
Use Ö14 or Ö16 drill bit to drill holes at the marked points on the floor.
Caution:
1. Generally, the selected drill bit is bigger than the expansion bolt. If the hole diameter is too small for
the F14 drill bit, enlarge the hole diameter by technical means.
2. Hold the drilling bit vertical to the floor during drilling. Hold tight the drillstock with two hands to keep it
in the right direction, as vibrations of the drill may damage the floor or produce a slanting hole.
3. The hole depth should be the length of the expansion bolt stem plus the drill bit. All holes should
share the same. Before measuring the hole depth, remove the dust inside the hole with a vacuum
cleaner, then drill again if necessary.
4. If the ground is too hard and smooth to settle the drill bit, punch out a pit with a chisel before drilling.
Marking and drilling hole are fundamental to the hardware installation. If the result is
not accurate, it will bring trouble for the future work. Thus the quality at the initial
stage is the prerequisite for the whole project.

4.1 Installing Boards of Baseband Subrack
The baseband subrack is located at the cabinet–uppermost part. The boards
inserted in this subrack are common boards. One connector is equipped at the rear
of a board and used to connect to the backplane. On the front of the board are two
metal handles with spanners used to pull out and plug in the board.
The installation procedures of the board are as follows:
1)
Align the board with the positions marked with corresponding board names and
push in the board gently along the guide rail until explicit resistance can be felt,
then lock the front panel.
2)
Fasten all screws one by one in position on the panel with a screwdriver, to
ensure that it is seamless between the board panel and the baseband subrack.
Caution:
1. Before installing the board, first check the cleanness of the cabinet and the subrack. Clean the
cabinet and the frame if necessary.
2. Wear antistatic wrist strap (Make sure that the plug of the antistatic wrist strap is inserted in the
socket on the sidedoor post of the cabinet) or discarge the static on the body by touching the chassis
before touching the board or the module.
3. Insert the boards strictly according to the labels on the individual nameplates. Do not insert the
boards wrong.
4. Insert the board vertically into the subrack and the boards are interconnected through the system
bus on the backplane.
5. Insert the boards with care so as to prevent the pins from getting bent on the backplane.
4.2 Installing Other Functional Modules
Refer to the following procedures for installing the fan box, power supply module,
BTRM module, BHPA module, BTRM fan module, RLDU module and the CDU
module.
1)
Align the fan box, power supply module, BTRM module, BHPA module, BTRM
fan module, RLDU module, and the CDU/DFU/DDU module respectively with
the “fan subrack”, “power supply subrack”, “RF subrack”, “RLDU/CDU subrack”
4-1
Installation Manual
Airbridge cBTS3612 CDMA Base Station
Hardware Installation
Installation of Cabinet Modules and Parts
and so on, then push them in gently along the corresponding guide rails until
explicit resistance can be felt.
2)
Fasten all screws into position on the panel one by one with a screwdriver to
ensure that it is seamless between module panel and the cabinet subrack.
Caution:
1) The transmitting and receiving indexes of the BTS will probably descend if the BTRM, CDU, DFU,
DDU, RLDU and other RF modules are not inserted correctly and the screws are not fastened.
Meanwhile, the CDU frequency is fixed and not adjustable. Its corresponding upper subrack probably
has higher carrier frequency, while the lower subrack has relatively lower carrier frequency. Decide the
slot position of the specified carrier frequency module according to the actual frequency in pratical
configuration, otherwise, it will result in such faults as low transmitting power of the BTS.
2) When DFU and DDU are used, they have no special requirement on frequencies, and are
configured from bottom up in the subracks.
Installation processes of fan box, BTRM module, BHPA module, and BTRM fan
module are shown in Figure 4-1. And the installation processes of other modules are
similar.

screws on the side door; thus, that is the whole process.
II. Installing or disassembling rear doors
For the installation or disassembly of the rear door, align rear door with positioning
pin of the lower enclosure frame at the back of the cabinet, and install or
disassemble the six captive screws on the rear door. Thus that is the whole process.
III. Installing or disassembling left-front door and right-front door
During the installation for right-front door, align the door with the positioning pin at
the right-front of the cabinet, pull the pin at the upper part of the right-front door and
align it with the pin hole, thus ending the installation. The process for disassembling
the right -front door is exactly reversed.
The process for installing or disassembling left -front door is similar to that for
