3.5.2 Connections of Power Cables and PGND Cables in the Cabinet

The power cables in the cabinet are used to connect the power distribution box to the subrack

and independent fan subrack, thus ensuring stable power supply to the subrack and independent

fan subrack. The PGND cables are used to connect the cabinet to the grounding bar in the

equipment room, thus protecting the cabinet from electrostatic discharge.

Figure 3-5 shows the connections of the power cables and PGND cables in the BSC6900 cabinet.

BSC6900 GSM

Hardware Description 4 Components of the Cabinet



4-1



4.1 Power Distribution Box

Each cabinet must be configured with a power distribution box, which is installed at the top of the cabinet.

The power distribution box provides lightning protection and power surge protection for the four

-48 V inputs and supplies two groups of power to the parts of the cabinet. Each group has four

-48 V outputs and four RTN outputs. The power distribution box also detects the status of input

voltage and the output power, and generates audible and visual alarms when faults occur.

4.1.1 Front Panel of the Power Distribution Box

The components on the front panel of the power distribution box are the panel of the power

allocation monitoring unit (PAMU) and the power distribution switches.

4.1.2 Rear Panel of the Power Distribution Box

The components on the rear panel of the power distribution box are the power input terminal block, power output terminal block, port used to connect the power distribution box to a subrack,

and a 2-hole grounding screw.

4.1.3 Technical Specifications of the Power Distribution Box

This section describes the technical specifications for the input and output power supply of the

power distribution box.

4.1.4 Distribution of Power Switches on the Power Distribution Box

The power distribution box of the cabinet has 20 (10 x 2) power outputs. There is a fixed relation

between the eight outputs of the power distribution box at the top of the cabinet and the intra-

cabinet components.

4.1.1 Front Panel of the Power Distribution Box

The components on the front panel of the power distribution box are the panel of the power

allocation monitoring unit (PAMU) and the power distribution switches.

Figure 4-1 shows the front panel of the power distribution box.

Issue 03 (2009-12-05)



NOTE

l For details about the PAMU board, see 6.11 PAMU Board.

l When the power distribution box is reset, the RUN and ALM LEDs turn on at the same time,

indicating that the PAMU board is performing self-check. As soon as the self-check is complete, the

RUN and ALM LEDs turn off. Then, the RUN and ALM LEDs display the operating status of the power distribution box.

The mute switch is set to determine whether an audible alarm is generated.

l If you set the mute switch to I, the power distribution box generates an audible alarm when

it is faulty.

l If you set the mute switch to O, the power distribution box does not generate any audible

alarm when it is faulty.

The front panel of the power distribution box has two LEDs: RUN and ALM.

Table 4-1 describes the LEDs on the front panel of the power distribution box.

Table 4-1 LEDs on the front panel of the power distribution box

LED Color Status Description

RUN Green ON for 1s and OFF for

1s

The PAMU board is functional and

communicates with the SCUa board

properly.

ON for 0.25s and OFFfor 0.25s

The PAMU board is faulty or it does notcommunicate with the SCUa board

properly.

OFF There is no power supply to the PAMU

board or the power distribution box

does not work properly.

ALM Red OFF There is no alarm related to the power

distribution box.

ON The power distribution box is faulty.

During the self-check of the PAMU

board, however, the ALM LED is alsoON. This indicates that the ALM LED

is functional.

4.1.2 Rear Panel of the Power Distribution Box

The components on the rear panel of the power distribution box are the power input terminal

block, power output terminal block, port used to connect the power distribution box to a subrack,

and a 2-hole grounding screw.

Figure 5-5 Cover plate for the DIP switch on the subrack

Description about the DIP Switch

The DIP switch on the subrack has eight bits numbered in ascending order from 1 to 8. Thehigher the bit is, the more significant it is. Table 5-6 describes the bits.

5 Subracks

BSC6900 GSM




Issue 03 (2009-12-05)



Table 5-6 Description about the bits

Bit Description

1-5 Bits 1 to 5 are used for setting the subrack number. Bit 1 is the

least significant bit. If the bit is set to ON, it indicates 0. If the bitis set to OFF, it indicates 1.

6 Odd parity check bit

7 Reserved, undefined, generally set to ON

8 (the most significant

bit)

Reserved

Principle of the DIP Switch Setting

As the DIP switch uses odd parity check, the number of 1s in the eight bits must be an odd

number. The method for setting the bits is as follows:

1. Set bit 1 to bit 5 as required.

2. Set bit 7 to ON.

3. Check the number of 1s in the seven bits of the DIP switch. Note that the setting of bit 8

remains unchanged.

l If the number of 1s is even, set bit 6 to OFF.

l If the number of 1s is odd, set bit 6 to ON.

Assume that the subracks are numbered from 0 to 2 and that bit 8 is set to OFF. Table 5-7describes the setting of the DIP switch in the case.

NOTE

l All DIP switches are on the front panel of the sub-board. The front panel is combined with the bottom

plate, so the DIP switches are not exposed.

l DIP switches S2, S4, S6, S8, and S10 are set from the side. As shown in Figure 6-15, there are two

square holes between DIP switches, one between S2 and S4, and the other between S8 and S6. Throughthe two holes, you can set S2, S4, S8, and S6. DIP switch S10 is located in the right corner of the sub-

board, and thus you can set S10 along the side.The direction of the arrow in Figure 6-15 is to turn

inwards. To set the bits of S2, S4, S6, or S8 to ON, turn them inwards. To set the bits of S2, S4, S6, or

S8 to OFF, turn them outwards. To set the bits of S10 to ON, turn them outwards. To set the bits of

S10 to OFF, turn them inwards.

l You can also run the SET E1T1 command on the LMT to set S10. If there is any inconsistency between

the physical setting of S10 on the AEUa board and the setting of S10 by command, take the setting by

command as the criterion. By default, the working mode of S10 is set to E1. You can also run the SET

E1T1 command on the LMT to change the working mode of S10 from E1 mode to E1 balanced mode,

E1 unbalanced mode, or T1 mode. When you run the SET E1T1 command to set the support for

balanced and unbalanced modes parameter to No and set the working mode of S10 to E1, you must

also manually set the bits of S10 to set the working mode of S10 to E1 balanced mode or E1 unbalanced

mode.l If signals are transmitted in E1 unbalanced mode, the signals are transmitted through the 75-ohm coaxial

cable and the TX end of the cable is grounded, that is, the corresponding DIP bit is set to ON. If signals

are transmitted in E1(T1) balanced mode, the signals are transmitted through the 120-ohm twisted pair

cable and the TX end of the cable is not grounded, that is, the corresponding DIP bit is set to OFF.

DIP switches S2, S4, S6, and S8 on the PEUa board are used to enable or disable the grounding

of 0 to 31 E1s/T1s/J1s at the TX end. DIP switch S10 is used to set the working mode to E1

balanced mode, E1 unbalanced mode, T1 mode, or J1 mode. Table 6-47 describes S2, S4, S6,

S8, and S10.

The line clock signal cable is optional. Two to four line clock signal cables can be installed to

transmit the line clock signals which are received from the interface board of the EPS to the

GCUa board.

NOTE

When the interface board providing line clock signals is located in the MPS, the line clock signals are sent

to the GCUa board through the backplane of the subrack. In this case, the line clock signal cable is not

required.

Description about the DIP Switch

The DIP switch on the su brack has eight bits numbered in ascending order from 1 to 8. The

higher the bit is, the more significant it is. Table 9-1 describes the bits.


BSC6900 GSM




Issue 03 (2009-12-05)



Table 9-1 Description about the bits

Bit Description

1-5 Bits 1 to 5 are used for setting the subrack number. Bit 1 is the

least significant bit. If the bit is set to ON, it indicates 0. If the bitis set to OFF, it indicates 1.

6 Odd parity check bit

7 Reserved, undefined, generally set to ON


bit)

Reserved

Principle of the DIP Switch Setting As the DIP switch uses odd parity check, the number of 1s in the eight bits must be an odd

number. The method for setting the bits is as follows:

1. Set bit 1 to bit 5 as required.

2. Set bit 7 to ON.

3. Check the number of 1s in the seven bits of the DIP switch. Note that the setting of bit 8

remains unchanged.

l If the number of 1s is even, set bit 6 to OFF.

l If the number of 1s is odd, set bit 6 to ON.

Assume that the subracks are numbered from 0 to 2 and that bit 8 is set to OFF. Table 9-2

describes the setting of the DIP switch in the case.

NOTE

l When the 75-ohm coaxial cable is used, the signal transmission uses the E1 unbalanced mode. In this

case, the TX end is grounded, that is, the corresponding bit of the DIP switch is set to ON.

l When the 120-ohm twisted pair cable is used, the signal transmission uses the E1(T1) balanced mode.

In this case, the TX end is not grounded, that is, the corresponding bit of the DIP switch is set to OFF.

l All DIP switches of the EIUa board are on the front panel of the sub-board. The front panel is faced to

and combined with the bottom plate, and so the DIP switches are hidden in between.

NOTE

In the BSC6900, the DIP switch on the PAMU board must be set as described in Table 9-5.

9.4 DIP Switches on the PEUa BoardThe PEUa board provides five DIP switches, namely, S2, S4, S6, S8, and S10.

Figure 9-4 shows the layout of the DIP switches on the PEUa board.

Figure 9-4 Layout of the DIP switches on the PEUa board


BSC6900 GSM




9-7



NOTE

l All DIP switches are on the front panel of the sub-board. The front panel is combined with the bottom

plate, so the DIP switches are not exposed.

l DIP switches S2, S4, S6, S8, and S10 are set from the side. As shown in Figure 9-4, there are two

square holes between DIP switches, one between S2 and S4, and the other between S8 and S6. Throughthe two holes, you can set S2, S4, S8, and S6. DIP switch S10 is located in the right corner of the sub-

board, and thus you can set S10 along the side.The direction of the arrow in Figure 9-4 is to turn

inwards. To set the bits of S2, S4, S6, or S8 to ON, turn them inwards. To set the bits of S2, S4, S6, or

S8 to OFF, turn them outwards. To set the bits of S10 to ON, turn them outwards. To set the bits of

S10 to OFF, turn them inwards.

l You can also run the SET E1T1 command on the LMT to set S10. If there is any inconsistency between

the physical setting of S10 on the AEUa board and the setting of S10 by command, take the setting by

command as the criterion. By default, the working mode of S10 is set to E1. You can also run the SET

E1T1 command on the LMT to change the working mode of S10 from E1 mode to E1 balanced mode,

E1 unbalanced mode, or T1 mode. When you run the SET E1T1 command to set the support for

balanced and unbalanced modes parameter to No and set the working mode of S10 to E1, you must

also manually set the bits of S10 to set the working mode of S10 to E1 balanced mode or E1 unbalanced

mode.l If signals are transmitted in E1 unbalanced mode, the signals are transmitted through the 75-ohm coaxial

cable and the TX end of the cable is grounded, that is, the corresponding DIP bit is set to ON. If signals

are transmitted in E1(T1) balanced mode, the signals are transmitted through the 120-ohm twisted pair

cable and the TX end of the cable is not grounded, that is, the corresponding DIP bit is set to OFF.

DIP switches S2, S4, S6, and S8 on the PEUa board are used to enable or disable the grounding

of 0 to 31 E1s/T1s/J1s at the TX end. DIP switch S10 is used to set the working mode to E1

balanced mode, E1 unbalanced mode, T1 mode, or J1 mode. Table 9-6 describes S2, S4, S6,

S8, and S10.
