2.3.1 Load-Bearing Capacity Requirements

Install the BTS3012AE on a stable and level cement floor. The weight capacity of the floor

must satisfy the weight requirement of the cabinet. If the BTS3012AE is installed on the

rooftop, the weight capacity of the rooftop must meet the weight requirement of the cabinet.

� If the weight capacity of the cement is more than 800 kg/m2, install the cabinet on the

cement floor. For details, see section 3.1 "Installing a Cabinet on the Cement Floor with

Sufficient Bearing Capacity (ƒ 800 kg/m2)."

� If the weight capacity of the cement is less than 800 kg/m2, install the cabinet on the

U-bar support that is on the cement floor. For details, see section 3.2 "Installing a

Cabinet on the Cement Floor with Insufficient Bearing Capacity (< 800 kg/m2)."

2.3.2 Grounding Status Requirements

Proper grounding ensures stable operation of the equipment. It is also the prerequisite for the

access network to be protected from thunder strokes or interference. Carefully check the

grounding conditions on site to ensure proper grounding.

To protect the equipment from a lightning discharge, the earth resistance of the grounding

system is recommended to be less than 10 ohms, and the equipment grounding should be in

accordance with national and local electrical codes as well.

2.4 Unpacking and Inspecting

This section describes how to unpack and inspect items from the following aspects:

� Requirements for Unpacking

� Unpacking the Wooden Case

� Inspecting Items Inside the Wooden Case

� Unpacking the Carton

� Inspecting Items Inside the Carton

2.4.1 Requirements for Unpacking

After the project kicks off, the project supervisor must check the products along with the

customer.

� The AC power cables for the BTS3012AE are purchased at the local place. The colors of the cables

must comply with the local rules and regulations. If the local rules and regulations have no special

requirements for cable colors, use the cables delivered together with the BTS.

� The default color of the delivered L wire is red and that of the N wire is black.

� The OT terminals of AC power cables are made on site.

For details, see Table 1-5 "Types and installation positions of the cables."

Table 6-4 lists the rated voltage, rated frequency, and power distribution mode in different

modes.




Table 6-4 AC power distribution mode

Note: For example, if the rated voltage is 346/200 VAC, the circuit voltage is 346 VAC and the phase voltage

is 200 VAC.

6.2.2 Installation Principles

Adhere to the following principles when installing the power cables:

� The power cables must be cut according to the measured distance between the wiring

terminals and the power interface box. Redundant length must be reserved.

� Replace the power cable of insufficient length with a new one. Do not make connectors

or solder joints.

� The power cables must be separated from other ones.

� If the power cables are laid parallel to other ones, the space between them must be at

least 30 mm.

� The power cables tied on the metal cabling rack must be insulated.

� Switches or fuses must not be added to the power cable.

� The E1 cables must be laid neatly and tied using cable ties. The space between the cable

ties must be 200 mm.

� The cable ties must be in one line and in the same direction. The ends of the cable ties

must be evenly cut.

After the power cables are led into the cabinet through the waterproof module, the slide plate in the

storage battery cabin is difficult to move out; therefore, the cable should be prepared with redundant

length.

6.2.3 Leading the 3-Phase 220 VAC Power into the BTS3012AE Cabinet

Perform the following steps:

Step 1 Remove the cover of the filtering box.

Take care not to damage the power cables connected to the socket on the cover.

Step 2 Determine the hole (in the waterproof module) through which the power cable is routed into

the cabinet.

6 Installing Cables




Step 3 Cut the cable according to the measured distance between the power interface box and the

wiring terminals N, L1, L2, and L3.

Step 4 Attach temporary labels to both ends of the cable.

The contents of the temporary labels can be the same as the formal ones or decided on site.

Step 5 Lay the cables. For details, see section 6.2.2 "Installation Principles."

Step 6 Make an OT terminal at one end of the external power cable.

Step 7 Lead the L1, L2, L3, and N wires with OT terminals into the cabinet through the waterproof

module. Secure the OT terminals to the wiring posts, as shown in Figure 6-6.

Step 8 Connect the other end of the external power cable to the power interface box.

Step 9 Remove the temporary labels and attach the formal ones.

The labels must be attached 20–50 mm away from each end.

----End




6.2.4 Leading the Single-Phase 220 VAC Power into the BTS3012AE Cabinet

Ensure that the L wire and N wire are connected correctly in single-phase mode. If not, the

lightning arrester can be burnt, which causes serious faults.

In single-phase mode, two methods are used to lead the L wire into the BTS3012AE cabinet:

� The single-phase power provided by the customer is divided into three channels in the

power interface box before led into the BTS3012AE.

For how to connect the cables, see section 6.2.3 "Leading the 3-Phase 220 VAC Power

into the BTS3012AE Cabinet."

� Install a short-circuiting copper busbar on the AC lighting arrester. Lead the single-phase

power provided by the customer directly into the BTS3012AE.

For how to connect the cables, see section 6.2.3 "Leading the 3-Phase 220 VAC Power

into the BTS3012AE Cabinet."

� 220 VAC input

To lead the 110 VAC dual-live power into the BTS3012AE cabinet, do as follows:

The external power network is single-phase or three-phase star mode.

Step 1 Remove the cover of the filtering box.

Take care not to damage the power cables connected to the socket on the cover.

Step 2 Determine the hole (in the waterproof module) through which the power cable is routed into

the cabinet.

Step 3 Cut the cable according to the measured distance between the power interface box and the

wiring terminals N, L1, and L2.

Step 4 Attach temporary labels to both ends of the cable.


Step 5 Lay the cables. For details, see section 6.2.2 "Installation Principles."

Step 6 Make an OT terminal at one end of the external power cable.

Step 7 Lead wires L1, L2, and N with OT terminals into the cabinet through the waterproof module.

Secure the OT terminals to the wiring posts, as shown in Figure 6-8.

6.3 Installing PGND Cables

6.3.1 Introduction to PGND Cables

The yellow and green PGND cables of the BTS3012AE have a cross-sectional area of 25 mm2.

Choose plastic insulation copper core cables with a cross-sectional area of at least 25 mm2

if

you prepare PGND cables yourself.

The yellow and green PGND cables of the transmission interface box and power interface box

have a cross-sectional area of 25 mm2. Choose yellow and green plastic insulation copper core

cables with a cross-sectional area of at least 25 mm2 if you prepare PGND cables yourself.


Adhere to the following principles when installing PGND cables:

6 Installing Cables




� Measure the accurate distance between the two grounding ends and reserve cables with

enough length. When laying out PGND cables, replace the cables if the reserved cables

are not long enough. Solder joint or connection is not allowed.

� The PGND cables must be separated from other ones.

� If the PGND cables are laid parallel to other ones, the space between the PGND cables

and the other cables must be at least 30 mm.

� If PGND cables need to be bound with the metal cabling rack before being laid out,

insulation measures shall be taken.

� Switches or fuses must not be added to the PGND cable.

� The connection points at both ends of the PGND cables shall be in good electrical

contact and anticorrosion measures shall be taken.

� The E1 cables must be laid neatly and tied using cable ties. The space between cable ties

must be 200 mm.


must be evenly cut.

The PGND cables after being routed into the cabinet through the waterproof module may

prevent the removal of the slide plate from the storage battery cabin. To ensure that the slide

plate can be moved in and out freely, keep property redundant length of the cables that have

6.11 Installing the Built-In Storage Battery and Its Cables

Huawei has two types of built-in storage batteries. The two types of storage batteries are similar in

appearance, but different in the distribution of positive and negative terminals. The following takes the

storage battery with the positive terminal at the left port and the negative terminal at the right part of the

battery as an example. If customers prefer to provide storage batteries themselves, storage batteries must

comply with the BTS3012AE configuration requirements.

6.11.1 Introduction to the Storage Battery Cabin

The BTS3012AE has two types of storage battery cabins: –48 V 50-AH storage battery cabin

and –48 V 150-AH storage battery cabin.




The –48 V 50-AH storage cabin of the BTS3012AE can be removed to form a 7 U space with

the reserved 2 U space. This space can be used to accommodate transmission equipment or

other equipment of the operators.

� Figure 6-28 (A) lists the full configuration of the BTS3012AE under the combination of

150 AH + 50 AH + 2 U.

� Figure 6-28 (B) lists the full configuration of the BTS3012AE under the combination of

150 AH + 7U.

After the –48 V 50 AH storage battery cabin is removed, it can not be used as the storage battery cabin

again because it cannot meet the sealing requirements. That is to say, the cabinet shown Figure 6-28 (A)

can be changed to the cabinet shown Figure 6-28 (B) while the cabinet shown Figure 6-28 (B) cannot be

changed to the cabinet Figure 6-28 (A).

7.3 Power-On Check





Take care of personal safety during the power-on check because high voltage is involved. A

fatal accident may occur if you touch the input current directly or indirectly through a wet

substance.

Before you turn the primary power supply to ON, use a multimeter to measure the resistance

between the input power and the earth and check whether they are short-circuited.

7.3.1 Cabinet Power-On Check

Before powering on the cabinet, ensure that the power cables and boards are disconnected.

The procedure for power-on check of a cabinet is as follows:

Step 1 Set all the power switches to OFF.

Step 2 Turn on the DC PDF to power on the cabinet.

Step 3 Measure the input voltage of the power distribution box on BTS3012AE cabinet. The range

allowed is –60 V to –40 V.

� If the voltage is within the range, the power-on check is complete. Continue with board

power-on check.

� If the voltage is beyond the range, go to the next step.

The rated voltage of the BTS3012AE cabinet is –48 V.

Step 4 Turn off the DC PDF to cut off the power supply to the cabinet.

Step 5 Measure the output voltage of the PDF. Check the installation and layout of power cables on

the cabinet top. Clear the faults.

Step 6 Measure the output voltage of the PDF again and take the cabinet power-on check.

If the results are normal, continue with board power-on check.

7.3.2 Board Power-On Check

Before power-on check of boards, ensure that:

� The cabinet passes the power-on check.

� All the power switches are set to OFF.

� All the cables are connected properly.

The procedure for power-on check of boards is as follows:

Step 1 Set the power switch of the FAN subrack to ON.

Step 2 Check whether the fan runs normally.

� If yes, infer that the power supply inside the cabinet is normal. Go to Step 4.

� If no, infer that the power supply inside the cabinet is not normal. Go to Step 3.

Step 3 Check whether the power cable connection of the FAN subrack is good. If no, reinstall the

cable, and then repeat Step 1.

Step 4 Set the power switch of the common subrack to ON.

Step 5 Check whether the indicators of the DTMU in the common subrack flash slowly (0.5 Hz).

� If yes, infer that the board has normal power supply. Go to Step 7.

� If no, infer that the board is not properly placed or there are other faults. Go to Step 6.

Step 6 Reinstall the boards or clear the faults. Then repeat Step 5.

For details about the status of indicators on boards, see the BTS3012AE Base Station Hardware

Description Manual.

Step 7 Set the power switch of the DTRU to ON. Check whether the indicators on the DTRU panels

flash slowly (0.5 Hz).

� If yes, infer that the DTRU has normal power supply. Go to Step 8.

� If no, infer that the DTRU is not properly placed or there are other faults. Clear the faults

and then repeat Step 7.

Step 8 Set the power switch of the DAFU subrack to ON, and check whether the indicators on the

DDPU panels flash slowly (0.5 Hz).

� If yes, the DDPU has normal power supply. The power-on check of the board is

complete.

� If the indicators are always on, infer that the DDPU is faulty. Go to Step 9.

� If the indicators are off, infer that the power supply fails. Go to Step 10.

� For states other than that mentioned previously, go to Step 11.

The DCOMs in the DAFU subrack do not need power and there are no indicators on them.

Step 9 Check the DDPU and the cable between the DDPU and the serial port on the DTRU. Reinstall

the cable and check whether the indicators on the DDPU panel flash slowly (0.5 Hz).

� If yes, infer that the DDPU has normal power supply. Board power-on check is complete.

� If no, go to Step 11.





Step 10 Check the power cables of the DDPU. Reinstall the cable and see if the indicators on the

DDPU panel flash slowly (0.5 Hz).

� If yes, infer that the DDPU has normal power supply. Board power-on check is complete.

� If no, go to Step 11.

Step 11 Contact Huawei for fault location. Clear the faults and then perform Step 8 again until the

indicators on the DDPU panels flash slowly (0.5 Hz).

7.3.3 Power-On Check of the Heat Exchanger

The procedure for the power-on check of the heat exchanger is as follows:

After inserting the PSUs into the cabinet, turn on the ACU/HX switch on the AC power

distribution box and the HEX switch on the power distribution box. Check whether the fan on

the heat exchanger rotates fast.

� If yes, the heat exchanger works normally. The power-on check of the heat exchanger is

complete.

� If no, the heat exchanger is faulty. Contact Huawei to replace the heat exchanger.

7.3.4 Power-on Check of the Batteries

The procedure for the power-on check of batteries is as follows:

Step 1 Set the multimeter on the DC scale.

Ensure that the negative pole of the multimeter is connected to the positive pole (red) of the

battery group, and the positive pole of the multimeter to the negative pole (black) of the

battery group.

Step 2 Follow the instructions listed in Table 7-4 to handle different values.

Table 7-4 Instructions to handling different values

Measured Value Handling Suggestion

Value > 0 The connection between the –48 VDC cable and the GND cable is

incorrect. Connect the two cables correctly, and then measure the

voltage of the battery again.

Value = 0 The cable connection of the batteries is incorrect, or the batteries

are faulty. Correct the connection or clear the battery faults, and

then measure the voltage of the battery again.




Measured Value Handling Suggestion

–43.2 V < Value < 0 Check whether the low voltage is caused by automatic discharge

after a long period.

If the low voltage is caused by automatic discharge after a long

period, press the ON button (located in the hole) on the PMU panel

using a proper tool. Wait until you hear a click sound. Then go to

the next step.

Otherwise, check whether the batteries are normal. If the batteries

are faulty, clear the fault, and then measure the voltage of the

battery again.

–57.6 V ≤ Value ≤

–43.2 V

The connection is correct.

Press the ON button (located in the hole) on the PMU panel using a

proper tool. Wait until you hear a click sound. Then go to the next

step.

Step 3 Turn off the AC power input switch, and check whether the BTS3012AE can work well with

reference to the board indicators.

� If yes, the batteries are functional. The power-on check of the batteries is complete.

� If no, the batteries are faulty. Go to Step 4.

Step 4 Press the button in the hole labeled OFF on the PMU panel to power off the battery. After the

fault is cleared, power on the BTS3012AE again until the BTS works well.

If all the power-on checks have been passed, the power supply system of the BTS is

functional.
