Components of the GBSR

This describes the inner components and outer components of the GBSR.

The outer components of the GBSR consist of the rack, side doors, front door, and rear door. The inner components of the GBSR consist of the power distribution box, subracks, air defence subracks, and rear cable troughs.

Table 1 describes the inner components of the GBSR.

**Table 1** Inner components of the GBSR
Component	Description	Refer to...
Power distribution box	Based on the power consumption of the GBSR, one BSC common power distribution box or one BSC high-power distribution box is configured.	BSC Common Power Distribution Box and BSC High-Power Distribution Box
Subrack	One to three GEPSs (GTCSs) are configured.	BSC Subracks
Air defence subrack	When the cabinet is configured with two subracks, one air defence subrack should be configured. When the cabinet is configured with three subracks, two air defence subracks should be configured.	Air Defence Subrack
Rear cable trough	Each subrack should be configured with one rear cable trough.	Rear Cable Trough

NOTE:

If the GBCR is in configuration type A, the GBSR should be configured with the BSC common power distribution box.
If the GBCR is in configuration type B, the GBSR can be configured with the BSC common power distribution box or the BSC high-power distribution box.
