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 pack 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 damage 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 equipment, 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.

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.

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

4.5 Installing Optical Fibers

When the BTS3606 connects to the ODU3601C, you need to install the optical fibers.

4.5.1 Distribution Principle of Optical Fibers

Observe the following principles when distributing and binding optical fibers:

z Do not bend an optical fiber to a right angle upon distribution. Make it round with

a diameter of no less than 8 cm. Optical fiber pairs must be bound in order.

z The optical fibers between cabinets can be distributed through the cabling rack,

or directly on the top of the cabinet for the consideration of a nice appearance.

z Keep the redundant optical fibers in the fiber management tray. Do not twist and

mix fibers; otherwise, it is difficult to identify them.

z Optical fibers must be distributed according to specific conditions and bound

properly. Those fixed onto the beam must be bound with the interval of 150 mm.

z Corrugated plastic tubes must be added to protect the fibers when they are led

out of the cabling rack.

4.5.2 Installing Optical Fibers to ODU3601C

When BTS3606 is connected with ODU3601C, optical fibers are led out from CCPMs

to the MTRM of ODU3601C.
