4.1 Power Distribution BoxA 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 grouphas four -48 V outputs and four RTN outputs. The power distribution box also detects the statusof input voltage and the output power, and generates audible and visual alarms when faults occur.

4.1.1 Front Panel of the Power Distribution BoxThe components on the front panel of the power distribution box are the panel of the PowerAllocation Monitoring Unit (PAMU) and the power switches.

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

Figure 4-1 Front panel of the power distribution box

(1) Panel of the PAMU board (2) RUN LED (3) ALM LED(4) Mute switch (5) Power switches (6) Labels for power switches

NOTE

l For details about the PAMU board, see 6.14 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, theRUN and ALM LEDs turn off. Then, the RUN and ALM LEDs display the operating status of thepower 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 whenit is faulty.

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

NOTE

l Each subrack provides a total of 28 slots. The 14 slots on the front side of the backplane are numberedfrom 00 to 13, and those on the rear side from 14 to 27.

l Two neighboring slots, such as slot 00 and slot 01 or slot 02 and slot 03, can be configured as a pairof active/standby slots. A pair of active and standby boards must be installed in a pair of active andstandby slots. For example, if slot 00 is configured with the SPUa board, then slot 01 must be configuredwith the SPUa board and slot 01 cannot be configured with the SPUb board.

l Different types of boards can be installed in all slots other than active/standby slots. For example, ifslot 00 and slot 01 are configured with SPUa boards, slot 02 and slot 03 can be configured withSPUb boards.

l If the boards are in resource pool mode, then they can be installed in active/standby slots. For example,if slot 08 is configured with the DPUb board, slot 09 can be configured with the DPUe board.

Description about the DIP SwitchThe 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 5-4 describes the bits.

Table 5-4 Description about the bits

Bit Description

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



45

Bit Description

8 (the most significantbit)

Startup type of the subrack, generally set to OFF

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

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.

58

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

(1) Sub-board (2) Bottom plate



59

NOTE

l All DIP switches are on the front panel of the sub-board. The front panel is combined with the bottomplate, 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 twosquare 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 turninwards. To set the bits of S2, S4, S6, or S8 to ON, turn them inwards. To set the bits of S2, S4, S6, orS8 to OFF, turn them outwards. To set the bits of S10 to ON, turn them outwards. To set the bits ofS10 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 betweenthe physical setting of S10 on the AEUa board and the setting of S10 by command, take the setting bycommand as the criterion. By default, the working mode of S10 is set to E1. You can also run the SETE1T1 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 forbalanced and unbalanced modes parameter to No and set the working mode of S10 to E1, you mustalso manually set the bits of S10 to set the working mode of S10 to E1 balanced mode or E1 unbalancedmode.

l If signals are transmitted in E1 unbalanced mode, the signals are transmitted through the 75-ohm coaxialcable and the TX end of the cable is grounded, that is, the corresponding DIP bit is set to ON. If signalsare transmitted in E1(T1) balanced mode, the signals are transmitted through the 120-ohm twisted paircable 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 groundingof 0 to 31 E1s/T1/J1s at the TX end. DIP switch S10 is used to set the working mode to E1balanced mode, E1 unbalanced mode, T1 mode, or J1 mode. Table 6-4 describes S2, S4, S6,S8, and S10.

Figure 7-10 Optical splitter/combiner

Classification

The optical splitter/combiner can be classified into the following types according to the modein which optical signals are transmitted:

l Single-mode optical splitter/combiner: The optical fiber of the single-mode optical splitter/combinter is yellow.

l Multi-mode optical splitter/combiner: The optical fiber of the multi-mode optical splitter/combiner is orange.

Application Scenario

When optical interface boards work in active/standby mode and optical transmission deviceswork in independent mode, optical splitters/combiners can be used to improve the redundancyperformance of optical interface boards.



183

CAUTIONOnly 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 thetransmission on the TX optical fiber for the active optical port is interrupted, the BSC6900reports a Multiplex Section (MS) Remote Defect Indication (RDI) alarm on the active andstandby optical ports. An automatic switchover, however, is not triggered between the activeand standby optical ports.

l The active and standby optical ports on BSC6900 interface boards are operational. Thetransmission is interrupted on the optical fiber between the optical splitter/combiner and theTX port on the peer equipment, and the BSC6900 reports a MS RDI alarm on the active andstandby optical ports. An automatic switchover, however, is not triggered between the activeand standby optical ports.

l The active and standby optical ports on BSC6900 interface boards are operational. Thetransmission is interrupted on the optical fiber between the optical splitter/combiner and theRX port on the peer equipment, and the BSC6900 reports a Loss of Signal (LOS) alarm onthe active and standby optical ports. An automatic switchover, however, is not triggeredbetween the active and standby optical ports.

One environment monitoring device is delivered with one RS485 signal cable (10 m) and one RS232 signalcable (2 m). Choose one signal cable based on the actual requirements. The RS485 signal cable isrecommended. Use the Ethernet cable as a substitute if the length of the delivered signal cable is notsufficient.

7.19 SFP+ High-Speed CableThe SFP+ high-speed cable connects the SCUb boards in different subracks.

Appearance

Figure 7-35 shows the SFP+ high-speed cable.

Figure 7-35 SFP+ high-speed cable

InstallationThe two connectors at the two ends of the SFP+ high-speed cable are connected to the 10GEthernet ports on the SCUb boards that are located in different subracks.

Length of SFP+ high-speed cableThe lengths of SFP+ high-speed cable can be three or five meters.

When two cabinets are configured in the BSC6900 and a SCUb board is configured for eachsubrack, the two cabinets must be installed side by side, because the length of SFP+ high-speedcable is limited.

9 DIP Switches on Components

About This Chapter

This chapter describes the DIP switches on the boards and subracks of the BSC6900.


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

9.3 DIP Switches on the AOUa BoardThe AOUa board provides two DIP switches, both of which are labeled S1. The two DIP switchesare used to set the mode of the two STM-1/OC-3 optical ports.

9.4 DIP Switch on the PAMU BoardThe PAMU provides an SW1 DIP switch.

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

9.6 DIP Switch on the PFCU BoardThe PFCU board has one DIP switch, which is named SW1 and consists of four bits. The DIPswitch is used to set the address of the PFCU board. When the PFCU board is configured in afan box of the service subrack, the address of the PFCU board is set to 1. When the PFCU boardis configured in the independent fan subrack, the address of the PFCU board is set to 4.

9.7 DIP Switches on the POUa BoardThe POUa board provides two DIP switches, both of which are labeled S1. The two DIP switchesare used to set the mode of the two STM-1/OC-3 optical ports.

Location of the DIP SwitchThe DIP switch is located on the lower back of the subrack. For details on the location of theDIP switch, see 5.2 Components of the Subrack.

AppearanceFigure 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 SwitchThe 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 9-1 describes the bits.



231

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 theleast 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


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 oddnumber. 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.

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.

Table 9-2 describes the setting of the DIP switch in the case.

NOTE



l You can also run the SET E1T1 command on the LMT to set S10. If there is any inconsistency betweenthe physical setting of S10 on the AEUa board and the setting of S10 by command, take the setting bycommand as the criterion. By default, the working mode of S10 is set to E1. You can also run the SETE1T1 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 forbalanced and unbalanced modes parameter to No and set the working mode of S10 to E1, you mustalso manually set the bits of S10 to set the working mode of S10 to E1 balanced mode or E1 unbalancedmode.



DIP switches S2, S4, S6, and S8 on the AEUa board are used to enable or disable the groundingof 0 to 31 E1s/T1/J1s at the TX end. DIP switch S10 is used to set the working mode to E1balanced mode, E1 unbalanced mode, T1 mode, or J1 mode. Table 9-3 describes S2, S4, S6,S8, and S10.
