BSC Power Cable

The BSC power cables are classified into external power cables and internal power cables. The power cables are mandatory, which consist of -48 V power cables and RTN power cables.

The BSC external power cables need to be installed on site. They are used to lead the power from the power distribution frame (PDF) to the power distribution box in the BSC. The BSC internal power cables are installed before delivery. They are used to lead the power from the power distribution box to each board and module in the BSC.

Table 1 lists the BSC external power cables.

**Table 1** List of the BSC external power cables
Name	Color	Cross-Sectional Area (Unit: mm²)	Connector Type/Installation Position (Power Distribution Box)	Connector Type/Installation Position (PDF)	Quantity
External -48 V power cable	Blue	25/35	Cord end terminal/-48 V input of the BSC6000 cabinet	OT terminal/-48 V output of the PDF	2 per cabinet
External RTN power cable	Black	25/35	Cord end terminal/-48 V input of the BSC6000 cabinet	OT terminal/-48 V output of the PDF	2 per cabinet

Table 2 lists the BSC internal power cables.

**Table 2** List of the BSC internal power cables
Name	Color	Cross-Sectional Area (Unit: mm²)	Connector Type/Installation Position (Power Distribution Box)	Connector Type/Installation Position (Subrack)	Quantity
Internal -48 V power cable	Blue	8	Cord end terminal/-48 V input terminal	OT terminal/-48 V output terminal	2 per subrack
Internal RTN power cable	Black	8	Cord end terminal/-48 V input terminal	OT terminal/-48 V output terminal	2 per subrack

The BSC external power cable and the BSC internal power cable have the same appearance, as shown in Figure 1.
