GBCR (Configuration Type A)

This describes the components, cable connections, and engineering specifications of the GBCR that is configured with the GBAM.

• Components of the GBCR (Configuration Type A)
  This describes the outer components and inner components of the GBCR.
• BSC Common Power Distribution Box
  Each BSC cabinet must be configured with one power distribution box, which is installed at the top of the BSC cabinet.
• Air Defence Subrack
  The air defence subrack is installed between two service subracks. It shields hot air from affecting the service subracks and forms a straight-through air channel. The air defence subrack is 1 U high.
• KVM
  The KVM is an integrated device, which consists of a keyboard, an LCD display, and a mouse. It serves as the operating platform for the GBAM. The KVM can be configured when the GBCR is in configuration type A.
• LAN Switch
  The LAN switch is installed in the GBCR. Each BSC should be configured with one LAN switch.
• Cabling Frame
  The cabling frame provides space for collecting the Ethernet cables of the LAN switch.
• GBAM
  There are three types of GBAM used in the BSC: IBM X3650T, C5210, and HP CC3310. The GBAM is installed in the GBCR. Each BSC can be configured with one GBAM.
• Rear Cable Trough
  The rear cable trough is used to route and bind the cables for the boards that are inserted into the rear slots of the subrack. Three fiber management trays are installed at the bottom of each rear cable trough. They are used to coil optical cables.
• GBCR Cable Connections (Configuration Type A)
  The cables of the GBCR consist of the power cables, PGND cables, and signal cables.
• Technical Specifications of the GBCR (Configuration Type A)
  The technical specifications of the GBCR consist of structural specifications and electrical specifications.
