If there are devices that cannot meet the requirements, it is advised for the customer to
make improvements or reinstall the devices meeting the specified requirements.
1.4 Unpacking
This section describes the requirements and procedures of unpacking wooden cases
and cartons.
1.4.1 Unpacking Requirements
After the project begins, the project supervisor must check the products together with
the customer.
Check the following points:
Huawei Technologies Proprietary
1-4
Installation Manual – BTS3606 Cabinet Installation
Airbridge BTS3606&3606A CDMA Base Station Chapter 1 Installation Preparations
The total number of products is consistent with the packing list attached to the
z
packing case.
z The arrival place is the installation site.
z The packing case is in good condition.
z The cabinet is placed upside down.
If the outer package is damaged or soaked; or the equipment is soaked and becomes
rusty, stop unpacking and find the cause. Feed back the situation to the local Huawei
Representative Office.
Note:
To protect the equipment and find out the cause, move the unpacked equipment indoor
for proper storage, and take a photo for the storage site, rusty or corroded equipment,
packing cases, and packaging materials. Keep these photos and store the unpacked
packing cases and packaging materials.
If the outer package is in good condition, follow the procedure below to unpack and
check the equipment:
1) Unpack the case labeled "contains Packing List”, and take out the Packing List.
Check the case according to the Packing List.
2) If shortage and miscarriage occur, fill in the Cargo Shortage and Miscarriage
Report.
3) If cargo damage occurs, fill in the Cargo Replacement Application Form.
4) Sign the Packing List together with the customer.
Caution:
When transporting and moving equipment, components, or parts, avoid them from
colliding with doors, walls, or shelves.
Never touch the uncoated surface of equipment, parts, or components with sweat
soaked or dirty gloves.

1.4.2 Unpacking Wooden Case
Caution:
Do not put the wooden case upside down. Otherwise, the equipment will suffer severe
damages.
Wooden cases are generally used to p ack heavy objects like racks, batteries, and so on.
A rack is usually packed with wooden boards, steel edges, tongues and foamed angle
wraps.
It is recommended to move the packing case into or near the equipment room (if
possible) to avoid damage to the cabinet during the transportation. The unpacking
procedure is as follows:
1) Insert one end of the ejector lever into a hole of the tongue on the cover of the
wooden case.
2) Turn the ejector lever to straighten the tongue, as shown in Figure 1-1. You can
also use a screwdriver or a hammer to handle the tongue.

Figure 1-3 Removing all left wooden boards
5) Unpack other cases in the same way.
When handling the cabinet, hold on the solid places such as the upper cable rack or
bone frame. Do not use too much force on places with poor rigidity, such as cable
supports, cable fixing beams, to avoid any damage to the cabinet or any accident.
Remove the lining board of the rack at the place where the cabinet is to be installed.
Otherwise, boards and signal cables may be damaged in the conveyance.
1.4.3 Unpacking Carton
Cartons are usually used to pack cables, circuit boards and terminal devices. During
transportation, these circuit boards are usually put in anti-static bags. When unpacking
the circuit boards, you need to take anti-static measures to avoid any dama ge to these
boards.
Meanwhile, pay attention to the temperature and humidity of the environment. To keep
the anti-static bag dry, you need to put desiccant in the bags so that it can absorb
moisture in the bags. After transporting the equipment to a place with higher
temperature and humidity, do not unpack it immediately until 30 minutes later.
Otherwise, moisture will condense on the surface of the eq uipment, causing damage to
it.
To open a carton, do as follows:
1) Check the types and quantity of boards inside the carton according to labels.
Huawei Technologies Proprietary

Installation Manual – BTS3606 Cabinet Installation
Airbridge BTS3606&3606A CDMA Base Station Chapter 1 Installation Preparations
2) Cut the straps using diagonal pliers.
3) Cut the tapes along the seams of the carton cover using a knife. To avoid
damaging equipment inside, do not apply too much force.
4) Open the carton and take out the foam materials.
5) View the labels of boards, and check whether the number of boards is consistent
with what is specified on the label of the carton. Then, take out the boards.
6) Check the number and type of boards against the Packing List, and then accept
them.

Note:
The antistatic floor height refers to the distance between the upper surface of the
antistatic floor and the cement floor.
The heights of A600 series support assemblies I, II, and III can be adjusted steplessly
within their adjustable ranges. You can adjust the heights by moving the upper and
lower supports.
Type IV assembly is a height-fixed support. It is suitable for ultra-high or ultra-low
antistatic floors. But the floor cannot be lower than 140 mm (5.5 in.).
III. Installation Method
Install the support in the floor-bracketing mode. That is, bracket the floor between the
cabinet and the support, and then run the bolts through the antistatic floor to fix the
cabinet and the support. In this way, the cabinet can be firmly fixed and supported.
IV. Quantity
Two supports are needed for each cabinet.
2.2 U-bar Support
I. Outline
The U-bar support is a big base made on the site. The recommended material for the
support is the 14b-3000 type of GB707-88 hot-rolled U-bar.
Figure 2-4 shows the outline of the U-bar support.

II. Assemblies
None.
III. Installation Method
You need to prepare the U-bar support on the site. For the specific method, see
section 2.6 “Installing Assemblies on Cement Floor with Poor Bearing Ca pacity”.
IV. Length
Determine the length of the U-bar support as needed.
2.3 Cabinet Layout Principle
The principle of cabinet layout is as follows:
The space between the cabinet back and the wall must be greater than 0.6m (24
z
in.).
The cabinet side can be installed against the wall.
z
The path with the width no less than 0.8m (32 in.) must be reserved in front of
z
the cabinet.
The cabinet must be positioned as close as possible to the feeder window to
z
reduce the length of the feeder cable.
It is recommended to lay three BTS cabinets in a row, as shown in Figure 2-5, one as
the main cabinet, the rest as auxiliaries.

To position the cabinet, proceed as follows:
1) Determine the installation position of the cabinet according to the positioning
dimensions specified in the project design and construction bluepri nt.
2) Place the lower support on the floor according to the cabinet layout.
3) Mark the positions of four connecting holes of the cabinet (Each cabinet has four
connecting holes).

II. Drilling Holes and Installing Expansion Bolts
Caution:
z The depth of the hole must range from 52 mm (2 in.) to 60 mm (2.4 in.) (the length
of the expansion tube plus that of the drill bit). Otherwise, the expansion bolt
cannot be fastened.
All holes must have the same depth. Before measuring the hole depth, remove the
z
dust inside the hole to measure the net depth.
If the floor is too hard and smooth to settle the drill bit, punch a pit with a chisel to
z
help positioning the hole.
Make sure that the expansion tube is completely buried in the ground lest.
z
Feed the guiding rib on the nut into the guiding slot of the tube first. Otherwise, the
z
expansion bolt can not be properly installed and secured.
To drill a hole and install the expansion bolt, proceed as follows:
1) Use the M12 expansion bolt and φ16 bit.
2) Hold the drill stock firmly with two hands, and keep the drill bit vertical to the
ground to drill a hole.
3) Clean the dust with a vacuum cleaner when drilling.
4) Take off the M12×70 bolt, spring washer, plain washer, and insulating washer,
as shown in Figure 2-7.

5) Feed the tube and the nut into the hole vertically and make sure that the guiding
rib on the nut meets the guiding slot of the tube, as shown in Figure 2-8.
6) Hammer the tube until it is completely buried in the ground.

III. Fixing the Lower Support
To fix the lower support, proceed as follows:
1) Place the insulating plate and the lower support in turn aligning with the four
expansion bolts.
