NOTE

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, 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.

Figure 5-5 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 5-6 describes the bits.




Issue 03 (2010-07-30)

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 03 (2010-07-30)

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

(1) Sub-board (2) Bottom plate



6-9

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.

Classification of the Optical Cable

According to the types of optical connectors at both ends of the cable, the optical cable can beclassified 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 opticalinterface board in the BSC6900, and the connector type at the other end of the cable depends on siterequirements.

l The LC/PC-LC/PC single-mode/multi-mode optical cable connects the optical interface board to theODF 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 withtemporary labels. If one end of the cable is connected to the TX port, the other end should be connectedto the RX port.

CAUTIONThe TX end and RX end of each optical cable must be connected correctly. Otherwise, the opticalsignals cannot be received or transmitted.

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

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. 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 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.
