Connections of Power Cables and PGND Cables in the GBCR (Configuration Type A)

The power cables of the GBCR are used to connect the PDF to the PDB. This ensures a stable power supply for the GBCR. The PGND cables are used to connect the cabinet to the PDF or to the grounding bar in the equipment room. This protects the cabinet from electrostatic discharge.

Figure 1 shows the GBCR configured with the IBM X3650T GBAM.
Figure 2 shows the GBCR configured with the C5210/HP CC3310 GBAM.
