For multiple pieces of equipment installed in a rack/cabinet, make a separate
ground connection from each piece of equipment to the NTBK80 grounding
block. See Figure 38.
If a piece of Data Communications Equipment installed in a rack/cabinet does
not have a ground lug, ground the rack to the NTBK80 grounding block. See
Figure 38.
When you ground the rack to the grounding block, the equipment is grounded
using the Single Point Grounding method, as shown in Figure 5 on page 34.
