Power consumption The cabinet power consumption equals the sum of powerconsumption of all subracks in the cabinet.It is recommended that the power distribution systemprovide a maximum of 5100 W power per cabinet tofacilitate capacity expansion.

Heat consumption The heat generated by a cabinet equals the total heatgenerated by all subracks in the cabinet.To facilitate capacity expansion in future, the airconditioning system installed onsite must be able todissipate a maximum of 4100 W heat from each cabinet.

Heat dissipation A fan and air defense frames are installed in a BSC cabinet.Air flows in from the bottom of the cabinet and flows outfrom the top of the cabinet, ensuring good heat dissipation.

WARNINGWhen the voltage of power supply is lower than the lower threshold of the input voltage scope,multiple boards will become abnormal at the same time.Therefore, check the power system if multiple boards are abnormal at the same time.

NOTE

The SFP+ high-speed cable has two length specifications: 3 m (9.84 ft.) and 10 m (32.80 ft.). The SCUb boardsinside the same cabinet are connected using the SFP+ high-speed cable. When the cabling distance between twosubracks in different cabinets is longer than 10 m (32.80 ft.), the SCUb boards in the two subracks need to beconnected using a multi-mode optical cable.

3.5.5 Connections of Signal Cables for the TCRThe signal cables for the TCR are the active/standby 75-ohm coaxial cable, active/standby 120-ohm twisted pair cable, optical cable, straight-through cable, SFP+ high-speed cable, inter-TNUacable, Y-shaped clock cable, and monitoring signal cable for the power distribution box.

For details on signal cables, see 7 Cables. Figure 3-12 shows the connections of the signal cablesfor the TCR.

NOTE

l The types of interface boards, installation positions of cables, and number of cables shown in Figure3-12 are taken as examples. The actual configurations depend on the site planning.

l Among the multiple TCSs configured in the BSC6900 cabinet, one TCS is responsible for forwardingthe OM signals from other TCSs, and this TCS is referred to as the main TCS. In Figure 3-12, thelowest TCS serves as the main subrack. In practice, any TCS can serve as the main subrack, and theSCUb board in the main TCS is connected to the SCUb boards in other TCSs in star topology.

5.1 Classification of SubracksBased on functions, subracks are classified into the main processing subrack (MPS), extendedprocessing subrack (EPS), and transcoder subrack (TCS).

MPSAs the main processing subrack, the MPS is configured in the MPR. Only one MPS is configuredin the BSC6900. The MPS processes the basic services of the BSC6900, performs operation andmaintenance, and provides clock signals for the system.

EPSAs the extended processing subrack, the EPS is configured in the MPR or EPR. It processes thebasic services of the BSC6900.

TCSAs the transcoder subrack, the TCS is configured in the MPR, EPR, or TCR in BM/TC separatedconfiguration mode. It performs transcoding, rate adaptation, and sub-multiplexing.

5.2 Components of the SubrackThe main components of the subrack are the fan box, slots, front cable trough, and backplane.

Structure of the SubrackIn compliance with the IEC60297 standard, each subrack is 19 inches in width and 12 U inheight. Figure 5-1 shows the construction of the subrack with the front and rear views of thecomponent layouts of the subrack.

74

Color Status Description

Red ON for 1s and OFF for 1s The fan box is registered and hasone of the following problems:l One-way power supply to

the subrackl Communication failurel Fans ceasing to run or

running at too low a speedl Fan box in an excessively

high temperature ortemperature sensor failure

ON for 0.25s and OFF for 0.25s The fan box is not registered andhas one of the followingproblems:l One-way power supply to

the subrackl Fans ceasing to run or

running at a too low speedl Fan box in an excessively

high temperature ortemperature sensor failure

NOTE

When the fan box is registered, the communication between the fan box and the SCUa/SCUb board in thesame subrack is established. When the fan box is not registered, the communication between the fan boxand the SCUa/SCUb board in the same subrack is not established.

Technical Specifications of the Fan Box (Configured with the PFCU Board)The technical specifications of the fan box refer to the space height, voltage, maximum power,detectable temperature range, and requirement for fan speed adjustment.

Table 5-3 lists the technical specifications of the fan box.

Table 5-3 Technical specifications of the fan box (configured with the PFCU board)

Item Specification

Space height 1.5 U (1 U = 44.45 mm)


Maximum power 150 W

Detectable temperature range -5°C to 55°C

Requirement for fan speed adjustment The speed of the fans can be adjusted from55% to 100% of the full speed.



75

NOTE

When the BSC6900 is powered on, when a subrack is reset, or when the BSC6900 is upgraded, the fansin the subrack run at full speed for a short period. This is the normal condition during system startup.

5.3 Slots in the SubrackThe backplane is positioned in the center of the subrack, and the boards are installed on the frontand rear sides of the backplane. Each slot provides a different switching bandwidth. Check thebandwidth of the slot before installing a board. A board must be installed in a slot with enoughbandwidth.

Structure of the SubrackFigure 5-3 shows the structure of the subrack.

Figure 5-3 Structure of the subrack

(1) Front slot (2) Backplane (3) Rear slot

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 XPUa board, then slot 01 must be configuredwith the XPUa board and slot 01 cannot be configured with the XPUb 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 XPUa boards, slot 02 and slot 03 can be configured withXPUb 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 DPUc board, slot 09 can be configured with the DPUf board.




76

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 5-4 shows the cover plate for the DIP switch on the subrack.

Figure 5-4 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 5-4 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



77

Bit Description

8 (the most significantbit)

Startup type of the subrack, the default value is OFF.NOTEl For the inventory sites upgrading from BSC6000 to BSC6900, keep

the former settings.

l For the new sites in BSC6900, the bit is conservative and is fixed toOFF.

CAUTIONl You must set the DIP switch before powering on the subrack. The setting after the power-

on is invalid.

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 5-5 describes the setting of the DIP switch in the case.

5.5 Configuration of the SubrackThe BSC6900 subrack configuration includes the typical configuration of the MPS, EPS, andTCS in different subrack configuration modes.

Principles for installing boards are as follows:

l The SCUa and SCUb boards must be installed in slots 6 and 7.

l The GCUa and GCUb boards must be installed in slots 12 and 13 in the MPS.

l The TNUa board must be installed in slot 4 or 5.

l The OMUa and OMUb boards can be installed in slots 0 to 3, slots 20 to 23, or slots 24 to27 in the MPS at the bottom of the MPR. For existing BSC6900s, the OMUa and OMUbboards can be installed in slots 20 to 23. For new BSC6900s, the OMUa and OMUbboards can be installed in slots 24 to 27.

l The OMUc board can be installed in slots 0 to 3, slots 20 to 23, or slots 24 to 27 in the MPSat the bottom of the MPR. Slots 24 and 25 are recommended.

l The XPUa/XPUb/DPUa/DPUc/DPUd/DPUf/DPUg board is preferentially installed in thefront slots of a subrack. These boards are installed in the rear slots of the subrack only whenthe slots in the front are occupied.

l Interface boards must be installed in the rear slots of a subrack to facilitate cable routing.

l Interface boards FG2c, GOUc, and UOIc are preferentially installed in slots 16 to 23,because these boards have a high processing capability. These boards can be installed inslots 14, 15, and 24 to 27 when slots 16 to 23 are occupied.

5.5.1 Configuration of the MPSThe boards installed in the MPS depend on the subrack configuration mode used by theBSC6900.

The boards that can be installed in the MPS are the OMUc, SCUb, GCUa, GCGa, TNUa, XPUa/XPUb, DPUf, DPUg, EIUa, FG2a/FG2c/FG2d, GOUa/GOUc/GOUd, POUc, OIUa, and PEUa.

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

Figure 6-23 shows the layout of the DIP switches on the PEUa board.



161

Figure 6-23 Layout of the DIP switches on the PEUa board




162

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 6-23, 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 therefore you can set S10 along the side. The direction of the arrow in Figure 6-23 is toturn 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 bitsof 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 betweenthe physical setting of S10 on the PEUa 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 6-68 describes the DIPswitches on the PEUa board.

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 SFP+ high-speed cable has two length specifications: 3 m (9.84 ft.) and 10 m (32.80 ft.). The SCUbboards inside the same cabinet are connected using the SFP+ high-speed cable. When the cablingdistance between two subracks in different cabinets is longer than 10 m (32.80 ft.), the SCUb boardsin the two subracks need to be connected using a multi-mode optical cable.

l The LC/PC-LC/PC single-mode/multi-mode optical cable connects the optical interface board to theODF or other NEs, or interconnects 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.

CAUTIONThe TX end and RX end of each optical splitter/combiner must be correctly connected.Otherwise, optical signals cannot be received or transmitted.

AppearanceFigure 7-10 shows the optical splitter/combiner.

Figure 7-10 Optical splitter/combiner

ClassificationThe 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 ScenarioWhen 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.



207

CAUTIONOnly the POUc board 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.

The RJ45 connector at the other endof the cable is connected to the J2 port on a high-capacity power distribution box or the COM1port on a common power distribution box.

NOTE

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.

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 EIUa BoardThe EIUa board provides five DIP switches, namely, S1, S3, S4, S5, and S6.

9.3 DIP Switch on the MDMC BoardThe MDMC board provides an S2 DIP switch.

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.

BSC6900 GSMHardware Description 9 DIP Switches on Components


256


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.



257

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, the default value is OFF.NOTEl For the inventory sites upgrading from BSC6000 to BSC6900, keep

the former settings.

l For the new sites in BSC6900, the bit is conservative and is fixed toOFF.

CAUTIONl You must set the DIP switch before powering on the subrack. The setting after the power-

on is invalid.

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.

9.2 DIP Switches on the EIUa BoardThe EIUa board provides five DIP switches, namely, S1, S3, S4, S5, and S6.

Figure 9-2 shows the layout of the DIP switches on the EIUa board.



259

Figure 9-2 Layout of the DIP switches on the EIUa board


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.

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 MDMC BoardThe MDMC board provides an S2 DIP switch.

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

Figure 9-3 DIP switch on the MDMC board

With four bits, the DIP switch S4 is used to set the address of the MDMC board.

To set the address, first remove the MDMC board and then set S2 as described in Table 9-5.

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

Figure 9-5 shows the layout of the DIP switches on the PEUa board.



263

Figure 9-5 Layout of the DIP switches on the PEUa board




264

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 9-5, 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 therefore you can set S10 along the side. The direction of the arrow in Figure 9-5 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 PEUa 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 9-7 describes the DIPswitches on the PEUa board.
