4.1 Power Distribution BoxEach cabinet must be configured with a power distribution box, which is installed at the top ofthe 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 inputvoltage 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 distribution switches.

4.1.2 Rear Panel of the Power Distribution BoxThe components on the rear panel of the power distribution box are the power input terminalblock, 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 BoxThis section describes the technical specifications for the input and output power supply of thepower distribution box.

4.1.4 Distribution of Power Switches on the Power Distribution BoxThe power distribution box of the cabinet has 20 (10 x 2) power outputs. There is a fixed relationbetween the eight outputs of the power distribution box at the top of the cabinet and the intra-cabinet components.

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, 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.

Issue 04 (2010-03-25)

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 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

8 (the most significantbit)

Reserved

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. 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.

Issue 04 (2010-03-25)

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 6-15, 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 6-15 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.

DIP switches S2, S4, S6, and S8 on the PEUa board are used to enable or disable the groundingof 0 to 31 E1s/T1s/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 6-47 describes S2, S4, S6,S8, and S10.

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


Reserved

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. 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 9-2describes 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 thiscase, 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 toand combined with the bottom plate, and so the DIP switches are hidden in between.

Table 9-3 describes the DIP switches on the EIUa board.

NOTE

l The DIP switches are set for 75-ohm coaxial cables by default.

l The setting for the DIP switches on the active board must be the same as that for the DIP switcheson the standby board.

l The RX end is not grounded either in balanced or in unbalanced mode.

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

Figure 9-3 shows the layout of the DIP switch on the PAMU board.

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




9-7

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 9-4, 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 9-4 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.

DIP switches S2, S4, S6, and S8 on the PEUa board are used to enable or disable the groundingof 0 to 31 E1s/T1s/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 9-6 describes S2, S4, S6,S8, and S10.
