5.2 BSC Common Power Distribution Box

Each BSC cabinet must be configured with one power distribution box, which is installed at the


The BSC common power distribution box provides lightning protection and overcur rent

protection for two -48 V inputs, which are then divided into two groups to supply power to the

functional modules in the BSC. (Each group has three -48 V outputs and thr ee RTN outputs.)The power distribution box also detects the input voltage and the output power, and generates

audible and visual alarms when faults occur.

l Figure 5-26 and Figure 5-27 show the connections of signal cables between a GMPS and a GEPS. If

there are more than one GEPS, you need to connect each GEPS to the GMPS directly. The connection

method is the same as the method of connecting the first GEPS to the GMPS.

l The types of interface boards, installation positions of cables, and number of cables shown in Figure

5-26 andFigure 5-27 are examples. The actual types of interface boards, installation positions of cables,

and number of cables depend on the site plan.

Meaning of the DIP Bits

The DIP bits are numbered in ascending order from bit 1 to bit 8. ON represents digit 0 and OFF

represents digit 1. Table 8-6 provides the definitions of the bits.

Table 8-6 Definitions of the DIP bits

DIP Bit Meaning

1 (the least significant bit) Subrack number setting bit

2 Subrack number setting bit




6 Odd parity check bit

7 Reserved, undefined, generally set to 0 (ON)

8 (the most significant

bit)

l For the GMPS, the bit should be set to 1 (OFF).

l For the GEPS and GTCS, the bit should be set to 0 (ON).

Bit 8 (the most significant bit) is used to set the startup mode of the GSCU in the subrack. Thedefinitions of this bit are as follows:

l If this bit is set to 0 (the status of the DIP bit is ON), the GSCU is set to Not Start

Automatically. The startup of the GSCU depends on the GOMU. In other words, when the

GSCU is started, it loads data from the GOMU.

l If this bit is set to 1 (the status of the DIP bit is OFF), the GSCU is set to Start Automatically.

When the GSCU is started, it checks whether the Flash file is valid. If the Flash file is valid,

the GSCU loads data from the Flash. If the Flash file is invalid, the GSCU loads data from

the GOMU.

Setting Scheme

As the DIP switches use odd parity check, the number of 1s in the eight DIP bits must be an odd

number. The setting should adhere to the following principles:

1. Set DIP bits 1 through 5 and DIP bit 8.

2. Set DIP bit 7 to 0.

3. Count the number of 1s that have been set.

l If the number of 1s is even, set DIP bit 6 to 1.

l If the number of 1s is odd, set DIP bit 6 to 0.

Assume that the subracks are numbered from 0 to 3. For the setting of the DIP switches in this

case, refer to Table 8-7. Subrack 0 should be the GMPS. Subracks 1 to 3 may be the GEPS or the GTCS.

bit)

l For the GMPS, the bit should be set to 1 (OFF).

l For the GEPS and GTCS, the bit should be set to 0 (ON).

Bit 8 (the most significant bit) is used to set the startup mode of the GSCU in the subrack. Thedefinitions of this bit are as follows:
