4.1 Power Distribution Box

A power distribution box is installed inside each cabinet at the top.

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 components in 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 switches.

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

l For details about the PAMU board, see 6.12 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


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.

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.

BSC6900 UMTS




52



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)

Startup type of the subrack, generally set to OFF.

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. Set bit 8 to OFF.

4. 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 5 and that bit 8 is set to OFF. Table 5-7

describes the setting of the DIP switch in the case.

BSC6900 UMTS




64



Figure 6-2 Layout of the DIP switches on the AEUa board

(1) Sub-board (2) Bottom plate

BSC6900 UMTS




65



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 6-2, 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 6-2 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.

Description of the DIP Switches

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

of 0 to 31 E1s/T1/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 6-4 describes S2, S4, S6,

S8, and S10.

7.3 Optical Cable

The optical cable is optional in the BSC6900. It is used to connect the optical interface board tothe Optical Distribution Frame (ODF) or other NEs. The number of optical cables to be installed

depends on the site requirements.

Classification of the Optical Cable

According to the types of optical connectors at both ends of the cable, the optical cable can be

classified into the following types:

l LC/PC-LC/PC single-mode/multi-mode optical cable

l LC/PC-FC/PC single-mode/multi-mode optical cable

l LC/PC-SC/PC single-mode/multi-mode optical cable

NOTE

l In actual installation, the LC/PC optical connector at one end of the cable is connected to the optical

interface board in the BSC6900, and the connector type at the other end of the cable depends on site

requirements.

l The LC/PC-LC/PC single-mode/multi-mode optical cable connects the optical interface board to the

ODF or other NEs or connects the optical interface boards.

l In practice, two optical cables form a pair. Both ends of each cable in the pair are attached with

temporary labels. If one end of the cable is connected to the TX port, the other end should be connected

to the RX port.

CAUTION

The TX end and RX end of each optical cable must be connected correctly. Otherwise, the optical

signals cannot be received or transmitted.

CAUTION

Only the AOUa, UOIa, AOUc, POUc, and UOIc boards can be connected to an optical splitter/

combiner.The optical splitter/combiner cannot be used to solve any of the following problems:

l The active and standby optical ports on BSC6900 interface boards are operational. When the

transmission on the TX optical fiber for the active optical port is interrupted, the BSC6900

reports a Multiplex Section (MS) Remote Defect Indication (RDI) alarm on the active and

standby optical ports. An automatic switchover, however, is not triggered between the active

and standby optical ports.

l The active and standby optical ports on BSC6900 interface boards are operational. The

transmission is interrupted on the optical fiber between the optical splitter/combiner and the

TX port on the peer equipment, and the BSC6900 reports a MS RDI alarm on the active and

standby optical ports. An automatic switchover, however, is not triggered between the active

and standby optical ports.

l The active and standby optical ports on BSC6900 interface boards are operational. The

transmission is interrupted on the optical fiber between the optical splitter/combiner and the

RX port on the peer equipment, and the BSC6900 reports a Loss of Signal (LOS) alarm on

the active and standby optical ports. An automatic switchover, however, is not triggered

between the active and standby optical ports.

Location of the DIP Switch

The DIP switch is located on the lower back of the subrack. For details on the location of the

DIP switch, see 5.2 Components of the Subrack .

Appearance

Figure 9-1 shows the cover plate for the DIP switch on the subrack.

Figure 9-1 Cover plate for the DIP switch on the subrack

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 UMTS




215



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)

Startup type of the subrack, generally set to OFF.

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. Set bit 8 to OFF.

4. 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 5 and that bit 8 is set to OFF. Table 9-2

describes the setting of the DIP switch in the case.
